The Votronic StandBy Charger enables simultaneous trickle charging of your starter battery whilst your leisure / auxiliary battery is being charged from a mains charger, solar panel or generator. This is ideal if the charging source connected to your leisure battery has only one output, but you want to be able to provide a maintenance charge to your starter battery to keep it topped up.  Ideal for over-wintering campervans, motorhomes or boats.

Activation of the unit is automatic and it only operates when it senses a charging voltage at the leisure battery, keeping the batteries electrically separated otherwise. The amount of current diverted from the charging source will vary depending on the charging conditions but it is limited to 3A maximum. The starter battery cannot be over-charged because the charging voltage is reduced by 0.6V before reaching the starter battery.

Fitting is very easy and does not require any re-configuration of existing electrical systems. The unit simply needs small gauge cable and suitable fuses to be fitted between its terminals and the positive terminals of the two batteries. 

Suitable for use with lead-acid batteries only (not for use with lithium technology) where both batteries have a nominal system voltage of 12V.

Designed and manufactured in Germany with a 3-year manufacturer's warranty.

Title says it all. You can pay loads for dc to dc charging, and in some cases that might be perfectly justified. For my setup - Vivaro campervan used at weekends through the season - what I needed was a simple way to have my leisure battery (charged by 200w solar roof panel) take care of my starter battery as well. We all know the dreadful sound of a diesel trying to spin over from a flat battery following a few weeks of not being run! As far as I can tell this little box is doing just that.

I used the split charge +ve feed wire from my starter battery, popped this little box in on the starter battery side of that feed (NOT the relay controled side) and ran a new wire to my solar-charged leisure battery. Van has started first time ever since... just two wires to consider!

Make sure you read the instructions and all will be well (don't forget to fit the supplied inline fuse for safety.)

This is the best bit of kit that I have bought for the price. Wired it in and it instantly started working. Now when I have it on electric hook-up it keeps both batteries charged up. Very pleased with it especially for the price.

I had installed a solar system for my leisure batteries but as we've not got out much this year, my starter battery went flat - this little gizmo allows the energy from the solar to also trickle charge the starter battery. 12Vplanet were ace - delivery was before expected date - all good, added to my favourite vendors and would recommend.

This is the second one I have bought for our campervans. They appear to work well, keeping the starter battery charged. Obviously it all depends on the size of each battery and if the inbuilt charger is switched on. So, in summery as long as the charger is on then the starter battery will receive a TRICKLE charge.

This allows the Solar panel to charge the Leisure battery and a lesser amount of charge is diverted to the Starter battery.
Very useful to maintain starter battery, with the vehicle alarm and tracker systems draining down the Starter battery. Good product, great idea.
