Victron Orion 12V 18A Smart Isolated DC-DC B2B Split Charge Kit.

These Battery to Battery (B2B) charging kits are designed to charge your vehicle's leisure battery whilst driving and are appropriate for vehicles with Smart alternators, usually Euro 5 / Euro 6 compliant alternators. 

This Kit consists of:

Victron Orion Smart 18amp Isolated Battery to Battery Charger (ORI121222120)
16mm Heavy Duty Flexible Battery Cable (2m of black as standard and variable red up to 7m depending on installation location)
2 x Victron Midi Fuse Holders
2 x Victron 60amp Midi Fuses
8 x 16mm M8 Battery Lugs


Fully programmable

- Battery charge algorithm (configurable) or fixed output.

- Smart alternator compatibility: engine running detection mechanism.

Adaptive 3-stage charge algorithm: bulk – absorption – float

- For lead acid batteries it is important that during shallow discharges the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery is completely recharged.


Remote on-off

A remote on/off switch or relay contact can be connected to a two-pole connector. Alternatively, the H terminal (right) of the two-pole connector can be switched to battery plus, or the L terminal (left) of the two-pole connector can be switched to battery minus (or the chassis of a vehicle, for example).

All models are short circuit proof and can be paralleled to increase output current

An unlimited number of units can be connected in parallel.

High temperature protected
