Battery to battery charger kits

Battery to battery charger kits allow you to install a battery to battery charger (sometimes referred to as a B2B charger or DC-DC charger) as part of your campervan electrical system. A B2B charger recharges your leisure battery via your vehicle’s alternator as you drive. The current rating of the charger signifies how quickly the charger will recharge your leisure batteries (e.g. a 30A charger will recharge your battery by 30A per hour).

All of our battery to battery charger kits include everything you need to fully connect the charger to your system. So, as well as the DC-DC charger, it all contains all cables, lugs, fuses and fuse holders. Simply select the size charger you need, and then choose any variables such as cable lengths and smart functionality.

Not only that, but all of our kits come with a free sub-system wiring diagram and installation guide. This explains exactly how to connect all the components, as well as how to correctly configure the settings. So, you can be confident in installing your system yourself.

What does a battery to battery charger kit typically include?

Our kits include every single component you need to fully install the subsystem within your campervan electrical system. So, as well as the main component, all cable, lugs, fuses, etc. are included.

There are some variables to choose from on our kits. For example, if you will connect to busbars or a Lynx Distributor – this will affect the required fuses for your system. So there may be some variation versus what you see below. However, this should give you a good idea of what’s included in each kit. The below shows an example of what’s included in the 30A non-isolated B2B kit with certain variables selected.
