Battery master and AGM/LA batteries (1 Viewer)

[SteveandSueJ]

Just changed MH. Veh battery is LA and Hab Is AGM. Going to fit my Battery Master but wondering as AGM charges and is full at higher voltages, is it safe for BM to trickle charge the LA battery which is full at a lesser voltage than AGM? Is the BM intelligent enough to stop charging the LA battery when full? May not have phrased it correctly but you guys know what I mean..!!!!! Appreciate your thoughts.... thx.

The battery master is unidirectional and operates on the basis of a voltage differential; if the starter battery drops below the differential delta a charge current will flow from the leisure battery.

The BM is a dumb device but physics means that no current will flow when the voltages equalises so your starter battery will not overcharge.

The simple answer is yes it will be fine, you’ll never really fully charge the engine battery anyway because of the quiescent drain on it

But when a battery is charged (full) you can’t force ‘more into it’ with the set up you described

Excellent guys, thank you...
