Well,
For faster capacity testing the whole pack i bought this one a while ago.
https://www.aliexpress.com/item/32883863452.html?spm=a2g0s.9042311.0.0.27424c4diPQNck
I does have a set v cut off, it gives a warning signal, when it reached your setting, but does not stop discharging
Its not accurate enough to get the capacity.
But oke.
I connected 3zb2l3 in parallel to discharge.
The first one in line hasa resistor of 5.6 ohm.
The other two have two parallel resistor(2x5.6 ohm)
When i connect them to the batteries for a discharge, they all discharge at ~1A.
Started them right after each other.
I would expect that the one with just one resistor, would discharge at 600ma.
When i set up everything again, and this time i only use the the one with one resistor, he does ~300ma.
Wait 10 seconds:
Set up the second one with two resistors, he does 600ma?!?!?!?
wait 10 seconds:
when i want the third one, it goes into overload/not properly wired?(error 5).
Can this be a proper way to measure capacity, for a whole pack?
Thanks in advance
