What's happening at 12 Volt Planet

Latest news for Oct 2017

This month we're discussing your options when it comes to selecting and wiring a fusebox and talking about the differences between parallel and series connections when wiring batteries together. Enjoy!

Which Fusebox?

Fitting a fusebox between your leisure battery and your 12V circuits is an essential bit of safety equipment when building a 12V system but it can be confusing when faced with various fusebox options.  Here we'll explain the main types available together with their advantages and disadvantages:

1. Fusebox with individual power supplies for each circuit

These fuseboxes only distribute power on the +ve side of the circuit and each circuit must be fed with an individual +ve supply cable. These are inexpensive but multiple cables can make installation time-consuming and complex if you have lots of circuits.

The -ve connections for each circuit cannot go through the box so need to be taken back to a suitable common -ve connection point or directly to the battery -ve terminal.

2. Fusebox with common power supply for all circuits

These fuseboxes tidy up the input wiring by having all circuits connected via an internal busbar (essentially a metal plate), so only one +ve power supply cable is required. These make installation cleaner and quicker but they tend to be slightly more expensive than boxes with individual power supplies for each circuit.

Again, the -ve side of each circuit cannot go through the box so need to be dealt with externally.

3. Fusebox with common power supply for all circuits, plus negative connections

These boxes go one stage further and have an internal busbar for the -ve side of each circuit as well as for the +ve. This means that you only need to wire one +ve cable and one -ve cable into the box, keeping the inputs really neat and tidy.

The -ve connections for each circuit can then be taken to the negative busbar in the box, so all your connections are in one place. In this example we've used twin-core cable for each circuit which makes the installation even more tidy.


Although more expensive, fuseboxes with busbars for both +ve and -ve sides of the circuits (example no. 3 above) are the option we recommend for most installations. They keep the number of connections to a minimum, make fault finding easy (no -ve connections hidden behind carpeted linings that are difficult to access) and, when combined with twin core cable, can result in very neat wiring installations. These are available in 6-way and 12-way versions.

Battery Wiring - Parallel or Series

One topic that causes a bit of confusion is the concept of wiring batteries together so we thought we'd take a couple of minutes to provide a brief overview.


If you want to increase your battery storage capacity by wiring two or more batteries together then you need to wire them in parallel. This means joining +ve to +ve and -ve to -ve. For two 12V batteries of the same size this will double your capacity in Ah but keep the voltage the same.


If you want to increase your battery voltage by wiring two or more batteries together then you need to wire them in series. This means joining the +ve of one battery to the -ve of the other.  For two 12V batteries of the same size this will double your voltage but keep the capacity in Ah the same.

Supporting TCB in Mongol Rally 2017

Monday, 27 March 2017  |  Craig

We are proud to support the Taking Care of Business Team (TCB for short) in this years 2017 Mongol Rally. The team will try and cross 25 countries clocking up 20,000 miles in the process with no help or support!

TCB, short for Taking Care of Business, is a team of the Mongol Rally 2017, comprising two couples; Geoff and Chloe, and Dom and Carla, from Mansfield Woodhouse and Warsop respectively. The gang decided that they would undertake the voyage to Mongolia (and back) during the latter months of 2016 and began planning. 

They spent several weeks trying to decide which model of car would best suit their needs. They settled upon the Morris Minor 1000s, and went about buying two of them, which have been named Georgina & Elaine.

The team then began preparing for the rally (work which continues to this day), deciding on which charities to support, working on the cars, route and logistics planning, fundraising, visas and more.

The charities they decided on (in addition to Coolearth, the official charity of the rally) were UNICEF, Mind and Cancer Research UK. The route that they have chosen for the outbound journey is known as 'the southern route' in Mongol Rally lore, and will see them traverse over twenty countries, and includes the infamous Pamir Highway in eastern and central Asia. They are travelling 'the northern route' on the return journey which sends them along almost the entire length of Russia.

To help them with there cars we have supplied them with the following parts for use during the rally as well as advice. 

7 Core Thin Wall Cable:

Crimp Terminal Kit:

High Power LED Work Lamp:

Twin USB Power Sockets:

The rally begins on 16th July 2017 & the entire trip is expected to last around two months, with the team trying to raise donations and sponsors for their causes before, during and after the rally.

We wish Geoff, Chloe, Dom & Carla the best of luck on this epic adventure and we hope you will join us in helping them raise as much money as possible for their chosen charities. We will follow their adventure throughout and keep you informed of their progress

Latest news for November 2016

This month we've added an LED Brightness Guide and Technical FAQ Section to our Knowledge Centre. We've also reduced shipping charges for Highlands & Islands destinations - great news for our customers in those more remote areas!

LED Brightness Guide

One of the questions we are often asked about our range of LED lights is 'How bright are they?'.  This is difficult to answer as LED lights cannot be directly compared with traditional incandescent light bulbs because they draw much less power for an equivalent light output. Most of us have a rough idea of how bright a 60W incandescent bulb is but we would probably have no idea how bright a 5W LED light would be. The brightness of LED lights is quoted in Effective Lumens and we have created a quick guide so you can compare traditional lighting wattages with Effective Lumens when deciding which LED lights are right for you.

Find out more: LED Lighting Brightness Guide

Frequently Asked Technical Questions

We often get asked the same sort of questions in relation to various 12V topics and we thought it was about time to pull together all the answers into a handy reference guide. So we've created a 12 Volt FAQs section in our Knowledge Centre and hopefully all your technical questions will be answered!

Highlands & Islands Shipping Costs Reducing

We are pleased to announce that from 1st December we will be bringing our shipping charges for Highlands and Islands destinations in line with the rest of the Mainland UK. So regardless of whether you live in London or Jersey you'll benefit from the same low, flat rate charge of £2.95 for standard shipping on all orders up to £100 and receive FREE shipping for all orders over £100.

See our Delivery & Returns section from 1st December for full details.



We Sponsor Team Mammoth Steppe In Their 10,000 Mile Charity Rally To Mongolia

Thursday, 5 June 2014  |  Paul

We're pleased to announce our sponsorship of Team Mammoth Steppe in their 2014 Mongolia Charity Rally entry. The Team are aiming to drive 10,000 miles un-aided from Birmingham to Mongolia through 3 deserts and 5 mountain ranges in a trusty LDV 4x4 van!

 At the end of their 5 week journey the team will donate the van to the Go-Help charity for use in Mongolia as there is around a 20% shortfall in the required number of ambulances in the country, and much of the terrain is rough and inaccessible without a 4x4.

In addition to supplying a vehicle to the Mongolian emergency services, any additional fund-raising will be donated to the Prince's Trust charity which supports young people in their transition from school to the workplace.

You can find out all about the team and their story at  which includes links for making a donation. To make it even easier for you we've included one here...JUSTGIVING.

We've supplied one of our popular split charge kits for the van to keep their auxiliary battery in top condition. These kits also ensure that the batteries are separated so the starter battery will never accidentally be drained and the team will always be able to start their vehicle.

We wish Alastair, George, James & Paddy the very best of luck in their adventure and we're going to be keeping a keen eye on their progress with the live progress tracking page provided on their website.



Our Top 5 Best Selling Marine Products Reviewed

Friday, 23 May 2014  |  Paul

We thought it would be interesting for you to know what others in the boating world are buying and have found useful in their projects, so here's a a run-down of our top 5 best selling marine products this year

5   Battery Isolation & Changeover Switches

The first in our Top 5 are these chunky marine battery switches. If you want to isolate the power to work on the circuit or need to disconnect in an emergency then these are essential. They are available either as a simple 2 position isolation (ON/OFF) type or as a 4 position changeover and isolation (1 ON / 2 ON / 1+2 ON / 1+2 OFF) type allowing you to switch between battery banks. These feel really solid in use, have a nice positive action and both types are rated at 300A continuous.


4    Waterproof Bulkhead Adaptors

These adaptors are designed to take un-split convoluted sleeving through bulkheads whilst maintaining a water tight connection. They are waterproof to IP67, can operate up to 120ºC continuously and are resistant to oils and fuels, making them ideal for routing wiring harnesses through the engine compartment or other harsh environments. We also stock a T configuration adaptor for convoluted sleeving, again water-proof to IP67.

If you combine these waterproof harness systems with our range of UK-made  tinned copper cable you'l have a system that will be superbly protected from the rigours of a marine environment and will give you many years of trouble-free service.



3    12-Way Fusebox With Power Buses

This fusebox has always been popular with car enthusiasts but is now gaining popularity for fitting on-board boats as well. It's a really nice piece of kit, solidly put together and with 12 circuits it should suit most small to medium sized electrical installations. There are 2 common +ve buses allowing you to have 2 independently powered banks of 6 circuits, and a common ground bus. The large, clear cover on this fusebox means it's ideal for use with with our LED 'glow' fuses that light up red when they blow to provide a clear visual indication of the fault - no more fumbling in the dark to identify the culprit!


2    Waterproof 12V Power Sockets

If you want access to 12V power for portable equipment in the cockpit or elsewhere on deck then the usual answer is to fit a 12V cigar lighter socket. These are ideal for the job but those designed for automotive use are not generally sealed and so are prone to water ingress and corrode as a result. We introduced a range of sockets this year to solve this issue which have a tight fitting, ribbed rubber cab that fits into the socket, combined with a gasket behind the socket surround to seal against the mounting face. This makes them waterproof when not in use and their corrosion-resistant construction ensures that any moisture that does get in during use won't corrode the terminals. They're made from impact resistant plastic and available in a range of styles to suit most applications.


1    Power Distribution Posts & Busbars

These stainless steel power posts and busbars are proving an extremely popular solution for on-board power distribution. They're tough, simple to fit and allow multiple connections, providing you with the flexibility to route power where you need it.  The 10-way and 4-way ones are the most popular and are available with covers to protect them from accidental shorting. Our recently introduced  4-way dual busbar version has also been selling well and provides multiple +ve and -ve connection in a single, compact block. 




12 Volt Planet Sponsors The Fire Fighters Race Team

Wednesday, 18 December 2013  |  Paul

The Fire Fighters Charity (formerly known as the Fire Services National Benevolent Fund) is the UK's leading provider of services that enhance the quality of life for serving and retired fire fighters, fire personnel and their families. They offer support for people in the fire and rescue community when they are in need and over the years have helped hundreds of thousands of individuals by providing world-class treatment and support services. It costs £9m/year to keep the charity running and, with no government funding, they are reliant on the generosity and enthusiasm of their supporters.

The Fire Fighters Race Team was an idea spawned by Dave Franks, a serving fire fighter and the Team Principle, which was to take a 1978 Mini saloon, strip it down and re-build it into a full-blown racing machine which will be used to raise awareness of the Fire Fighters Charity. The car will be exhibited at various fundraising activities, shows, hill climbs & sprints and will be entered in the 2014 South East Motor Sports Enthusiasts Club (SEMSECrace series.


Dave and his small but dedicated and hard working team are making great progress with the build and are now well on the way to getting the car prepared for the track with the body and chassis having recently been painted and vinyl wrapped. Part of the next stage of build will be to get the electrics installed and 12 Volt Planet are extremely proud to have been able to contribute in a small way by providing the wiring components and accessories needed.

You can find out all about the Fire Fighters Race Team including the latest build progress reports on their website:

Dave and the team will also be exhibiting the Mini at Autosport International 2014 at the NEC in Birmingham from 9-12 January, the World's greatest indoor motorpsort extravaganza with over 1 million sq ft of exhibitors and displays. So if you are planning to attend please visit their stand, say hello and show your support.

12 Volt Planet goes to TRAX 2013 Performance Car Show

Monday, 9 September 2013  |  Paul

We have to admit to having a weakness for all things 4-wheeled at 12 Volt Planet so when we were invited to TRAX 2013 at Silverstone we thought we'd head over to see what it was all about.

Trax is just one of a number of annual auto-shows organised by Future Publishing but is touted as the ultimate performance car event, and if you like your cars low, loud, modified and fast then this is most definitely the place for you. Being a multi-marque show there were representations from owners clubs of all the major manufacturers resulting in 100's of cars on display ranging from the subtly modified daily driver right through to the stripped-out track day rocket, with everything imaginable in between.

Drivers had the chance to experience the Silverstone circuit for themselves with track-time sessions and there were various motorsport events throughout the day, including drift demos and racing from some of the BTCC drivers . The good old British weather did put a bit of a dampener on proceedings in the afternoon but overall it was a great show with a huge turnout. If it sounds like your thing then we recommend checking it out in 2014.
