Eg 0.1 V difference for 0,01 Ohm will generate 10A
If you have 1V, it will be 100 A, it can grill one of the batteries, and at least melt the connection wires.
We can overcome this problem by placing a resistance of 10 Ohm, the batteries will balance gently (0.1 A if 1V difference), this resistance can be shunted thereafter as long as the batteries remain connected in parallel.
Oh yes it's a big risk! Can you briefer us a little bit on this?
Am a ball in this area, how is it measured?
I tested directly to the ohmmeter and I have this:
On the lithium I have on the general output between the 0 and 24V:
Infinite when the battery is on
0 by reversing the polarity
10.46 kOhm when off (????)
On 4 lead-acid batteries, I have infinity or zero depending on the polarity of the measurement.
Infinite when the polarity is respected (red on the +)
It's good I can wire?
