Battery to Battery Chargers

The Victron Bluetooth enabled Smart DC DC Chargers are fully programmable three stage chargers. Available in isolated and non-isolated models these take a charge from one battery and deliver it to another. The battery being charged can be a different chemistry, or even a different voltage. A remote on-off switch can be wired in to an engine ignition so the charger only works when the engine is running. They are also programmable based on voltage so they only run if the source battery is fully charged or is being charged.

If you are using this as a battery to battery charger then normally both batteries will be sharing the same negative so there is no need to purchase the isolated model. These devices can also be used for power conditioning and in that case the isolated model provides better insulation from electrical noise.

Programming is done on your phone or tablet using the Victron Connect App available for free from the Google or Apple app stores. You can try it out in demo mode before you purchase. These units can be ganged together for more output. MPPT Solar Charge Controllers may also be used as battery to battery chargers where the source battery is at a higher voltage then the destination battery.
