4 batteries in parallel questions

[Jazaddict]

I've got 4 200ah AGM in parallel.
I have a renogy 3000 inverter/charger.
Should I connect the charger to one battery at the end, or a pos from one, neg from another in the middle?

Will a charge balancer extend their life? I'd assume the balancer is between the AC output of the charger and the batteries... Or would it be better between the charge controller and the batteries?

I'm very green, type slow

I think it's preferred to connect the positive to the battery on one end and the negative to the battery on the other end (not in the middle). Make sure all your battery interconnects are the same length and the inverter/charger cables (pos & neg) are the same length.

I don't know anything about a balancer that works for AGMs???

Makes sense to go end to end.

I wasn't meticulous about exact lengths of bridge connections.... Theyre close ?


I've read that AGMS charge more evenly (er sumpin), but I also read that uneven recharge is a battery life shortener.
