So I have connected up a third LifePo4 in parallel with my existing two larger LifePo4 packs. The two larger are 204A each and the smaller 105A.
The smaller battery will in a few weeks be used to power my electric outboard trolling motor, as well as providing some extra capacity in the Motorhome power storage.
This will mean that the SOC both from a % of Amps and voltage, will be out of step with the two larger cells when I reintroduce it to the parallel set up.
Now, I can envisage a short Amp transfer spike when I first reconnect the smaller battery, but then I believe it will, with my VERY limited knowledge, quickly get up to a similar voltage to the other two larger batteries and once that voltage is equalised, will not draw anymore significant Amps.
99% of my charging is done via Solar and B2B and so when one of these charging source is introduced, post reconnection and the short Amp transfer spike, I then think that the small battery will just receive a disproportional share of the charging Amps until a happy balance is achieved.
Do people agree? Am I missing anything serious?
