Re: Chargery C10325 not doing CV phase?

I honestly am certain we can call these guys up and ask them. Want me to? Lol. I see a PRODUCT specificatin sheet, not a TESTING Specification sheet.. As PER the TITLE. I have seen a sheet specifically related to the testing of a cell, NOT only the selling... They are out there and used in ever day....

"Crap".
Temperature plays a huge role in storage battery engineering. How they work, the resistance top and bottom and the intrinsic current handling of the cell.

It has, since day 1, of battery engineering and the inherent chemistry.

Re: Chargery C10325 not doing CV phase?

Resistance climbs at the top and bottom of a cells charge and discharge cycles.

It is a fact of life. Sorry.

Lol @you again, Flippy.

The termination current is EXPLICITLY CIRCLED with the RED.

Those are test methods to reach the rated capacity, as you can see in that very section -- scroll down. What is the debate here? Do you think terminating the charge before CV is somehow damaging the cell? If i scould facepalm I would. It is the specified termination current . Related to the cells, ...

Re: Chargery C10325 not doing CV phase?

The idea of terminating based on amps tapering down is completely unnecessary just there to give a "last ditch" stop point to prevent harmful "even more overcharging" or for precision benchmarking with capacity / stress testing. So long as you are stopping **earlier** that is he...

Re: Balance Discharger... or is there anything else?

The M8 has very little balancing current. there are chargers with much better capabilities. Also, you cannot balance discharge on the M8, only balance charge. However if your (15Ah?) 8s6p is very out of balance the charger may terminate well before the balance is achieved. Some chargers have the opt...

Of course, the definitive answer is to test and measure, but I'm curious for current practices or opinions. I go all the way with balanced cells. Right to 4.2v / cell with well behaved cells. Not very well behaved cells watch like a hawk. I wouldnt bring them under 3.8-9v/ and wouldn't go over 4.1v...
