Hey All
Learning here so go easy.
When purchasing 2x 12v Lithium batteries for a 24v phoenix inverter, what is an allowable voltage deviation between the batteries when fully charged and settled prior to balancing them?
Both accept the full AH rating charge and a little more when charged from 100% DOD but one settles at 13.6v and the other at 13.1v. I would think this will cause issues when charging in a 24v arrangement?
Also when I put a load on the 13.1v battery it jumps up to 13.35v, then back down to 13.1v when disconnected. Making me think it is faulty and enough for me to return the battery for a replacement?
Any thoughts would be appreciated.
