I think you're asking about the load Amp Draw -vs- the battery Amp delivery capabilities. In a nut shell the fuse should be sized for the amount of current (amps) draws on that circuit. If you have a 12v battery that can delivery 600amp but you only have a single LED light pulling its supply...

Strange.... I took battery number three that I had a hard time charging and decided to discharge it to 2.5v and then tried again to charge it . This time it charged up to 3.62v and I did a full voltage discharge again to 2.5v and obtained a 60ah discharge from a 55aH battery. This would indicate...

Thanks Sunshine Eggo ... I was thinking the same for the charge and number of hours the current and the voltage weren't adding up. This cell should have been charged withing 8-10 hours from 3.113v to max Voltage 3.62v set on the supply.... well it looks like I've found the first bad cell so now...

I'm charging Cell#3 that was 3.113v been 22hrs power supply set to 3.62v amps set to 10 but cell only drawing at first 7amps dropping to 3.5amp over the total charging time of 22hrs,, Cell voltage is currently at 3.335v while charging . Voltage likely would be lower if I took it off the power...

Thank you, for your replies gentlemen, I guess I used the 8s2p backwards as pointed out :) . Yes t have a 24v pack with 8 cells 55amp each in series for a total of 24v. The second battery is made the same way as the first. Then I parallel them into a single 24v pack for 110amps. consisting...

I have built an 8s2p 24v pack with SAB 60280 cells. I built two packs one works perfectly charges and discharges great and all cells stay together within .010v while charging and discharging. The second pack will become unbalanced both charging and discharging by over 300mv differences. while...
