FAQS 3

How many amps should a short circuit current be?

Short circuit current should be limited by BMS to something around a few hundred amps. There is a small amount of time for BMS to react and shut down so for about 100-300 microsecs it can be couple thousand amps. Just curious, why are you looking for this? Are you doing this to calculate AIC for fusing?

How many Mohm does a battery take?

You're all assuming batteries to behave in an "ideal" way and they don't. The chemical processes inside the battery have their limitations. Of course you take 0,45 mOhm! You have to secure the battery by limit the current, you'll take max internal resistance which is 0,45 mOhm.

How do you measure battery impedance?

You can measure that with a 1 kHz battery impedance meter like a YR1035+. Each 100 AH LFP is typically spec'd at less than 0.5 milliohms for R_ohmic. There is four in series in 12v LFP plus about another 0.5-0.8 milliohms for BMS and wiring. A 280 AH cell is typically spec'd at 0.25 milliohms R_ohmic.
