The Sterling 'Pro Batt Ultra' 12V/12V 30A BB1230 Battery-To-Battery charger offers fast, multi-stage charging of auxiliary batteries in automotive, marine and recreational vehicle applications. Simple to install and configure, it provides a much deeper and faster re-charge than connecting directly to the alternator and is essential if you intend to re-charge a second battery in a modern vehicle where the introduction of 'smart' alternators has rendered traditional voltage sensitive relays (VSRs) redundant (please see download section below for more info).
Smart alternators are ECU controlled and their voltage output varies continuously throughout a journey. Often the voltage is too low to provide any charge to the batteries via a VSR and at other times the voltage is very high (with regenerative braking systems) which can damage sealed, AGM & Gel batteries.
Sterling Battery-To-Battery chargers take the variable voltage output from the alternator and boost or reduce it to maintain a stable voltage output according to a multi-stage charging profile, providing a safe, controlled and fast charge for your auxiliary battery. Another benefit is that current flow is limited by the charger's current rating, eliminating potentially damaging high in-rush currents to deeply discharged batteries and allowing the use of smaller connecting cable compared with VSR split charge systems (which need to handle the max. alternator output). Importantly, once the engine is turned off the charger automatically isolates the starter and leisure batteries from each other to prevent accidental discharge.
Compatible with the following manufacturer's technologies plus many other Euro 5/6 + vehicles that use smart alternators & regenerative braking.

Further info
We recommend this 30A charger for use in the majority of campervan and motorhome applications that have a leisure battery (or bank of batteries) up to around 300Ah in capacity. For larger battery banks and/or faster charge rates, consider the 60A model.

Easy to fit works like it should iv now had 2 of these been very good with no issues
Seems like a good product. Everything works straight out of the box just like the comprehensive instructions suggest.
Let me start by saying that this seems to be a perfectly good charger. It does its job, and it runs quietly and (so far at least) reliably. I would have given it 5 stars, but...The UI and the manual! The first impression of the manual is that it's one of those which has been translated from a foreign language by a non-native English speaker, but on further study I don't think that's right. It's just been written by someone who brain-dumpswithout reading it back and has a slightly odd writing style. It consistently uses the word "shall" when it means "will" (the two are not synonyms) and "alternatively" when it means "alternately". The biggest problem though is that it relies very much on you knowing what the author was thinking when he or she wrote it. The information isn't provided in any kind of structured way but just as a stream of the writer's consciousness. So much crucial information is left out that a lot of guesswork is involved in learning how to drive the unit.The front panel user interface is of the same style - loads and loads of LEDs with cryptic annotations. Much work is required to discover what it's trying to tell you. Some of the LEDs aren't explained at all - cryptically labelled, but not explained.Both manual and front panel have a really cramped appearance - as if someone was desperately trying to fit too much information into too little space. The manual needs a good editor to pull it apart, quiz the developers to fill in the lacunae, rearrange it in a waythat explains the principles of the device, then polish it to a readable form.The unit would be much better with a small LCD display on the front to replace almost all the LEDs, and two to four navigation buttons.To its credit, it does work satisfactorily just straight out of the box. Wire it up, turn it on and it works. The default settings are satisfactory for most installations, and if you're happy to treat it as an impenetrable black box then it's fine. I prefer to have a bit more understanding of what's going on though, and that's where it falls down. To get 5 stars the unit would need either a well-designed UI or a decent manual - currently it has neither.I would offer to write them a decent manual, provided I could have access to someone who could answer all the questions which the current one leaves unanswered.
Very good service my questions were answered very well however I found the instructions a bit sketchy to follow so I went on YouTube and watched the video and found that a lot easier to follow it’s only been 3 days since I have used my vehicle and it started with no problem Good piece of kit I would recommend
Fantastic product easy to install
As title says a really good quality product which was delivered the next day and via the very user friendly website.
Awesome product. I was struggling to keep my batteries over 12.3 volts (about 60%) with my normal vsr/alternator. After installing this product it really supercharged my batteries 30 mins to an hour for almost fully charged now. It even charges whilst just sitting with the engine on no need to drive around to charge up.
Great delivery , product as expected
I didn't know much about these and have had someone else fit. Seems to work perfectly but the service was excellent. Really took the time to explain things and delivery was quick. Thanks!
Looks a nice piece of kit, not fitted yet,(will update at that point.) Delivery and service top notch.
