Victron BCD 402 2 Batteries 40A (Diode Battery Combiner)

Diode Battery Combiners are used to guarantee continuous DC power to mission-critical
equipment, such as an electronic engine control system. With a diode battery combiner two
or more DC power sources can be used in parallel to supply the mission-critical load. Failure
of one source will not interrupt power to the critical load.
The Argo Battery Combiners feature a low voltage drop thanks to the use of Schottky diodes:
at low current, the voltage drop is approximately 0,3 V and at the rated output approximately
0,45 V.
Warning : hot surface, mount the Argo Diode Battery Combiner on a non-flammable surface
only!
