Battery to battery chargers vs voltage sensing relays
We have a whole blog post that discusses the differences between battery-to-battery and voltage-sensing relays. Your van is probably fitted with a smart alternator if newer than 2015. If so, you must choose a battery-to-battery charger like the Victron 12/12 30A DC-DC Charger to charge your leisure batteries.
VSRs are also not compatible with lithium batteries. So if you plan on using a lithium setup, we recommend choosing the Victron 12/12 30A DC-DC Charger to charge your lithium leisure batteries.
You can charge 12V lead acid, AGM and lithium batteries with the Victron battery to battery Charger. You can connect multiple units in parallel to increase power output and the 30A model will deliver up to 360W of power.
Isolated or non-isolated charger?
We always recommend using an isolated charger in campervan or other builds. The isolation may not always be necessary, but it provides an extra layer of protection for both your van’s circuits and your appliances.
Pair your device with the VictronConnect App and monitor your charging history and settings. The app provides the added benefit of easily checking both your start battery and leisure battery voltages.
