Splitters allow several battery packs to be recharged at the same time from a given power source (often the alternator) (as many packs as they have outputs) while isolating them
Two types of distributors are available:
- Lossless splitters (pro split system): This new generation of splitters is microprocessor controlled. In addition to distributing the alternator power with excellent efficiency (the voltage drop is 0.01V at full power), they offer other advanced features such as priority to the battery which must meet a high demand (such as when using the windlass), protection of the batteries in the event of a generator failure. This system is compatible with the external alternator regulator such as the pdar, the advantage being that it does not generate a power loss unlike the old model. The range extends from 60 to 180A and is available in two or three outputs.
- Conventional diode splitters with voltage drop: They perfectly isolate the battery banks but have the disadvantage of generating a voltage drop (due to the diode) that does not allow the batteries to be recharged at the appropriate threshold, unless the distributor is associated with an external alternator regulator such as the pdar. This system also leads to a loss of power. The range extends from 70A to 160A and is available in two or three output versions.
It should be noted, however, that regardless of the distribution system used, it does not replace an external alternator regulator such as the pdar or an alternator charger that allows an efficient charge cycle (IUoU) to be applied to service batteries.
