Hey Guys,
Question Part.1 - I have two solar king 100ah lithiums in parallel - I have recently bought an Orion 12/12/30amp DC-DC charger and was wondering if there is a best practice when it comes to making the output connections; essentially, a or b? Assuming the wiring was exactly the same lengths in each case.
Question Part.2 - Following on from that, would your advice change if there was an Victron 100/50 MPPT connected to the bottom bus bars as well?
Many thanks in advance, Peter
Option 2 is best practice, as either battery can be disconnected without disturbing charge to the other. Also individual battery charge currents can be simply checked with a clamp meter.
for part 2, yes - that is the purpose of bus bars.
Thanks a lot @Mike Dorsett, the disturbance of battery connection isn’t an issue - as they get pulled in/out of the car twice a month (or more, but good point) - I suppose my concern was whether or not Option.1[a] would be deleterious to the batteries themselves when charging - as it would make things a lot easier in my use case?
