Been learning a lot from this forum. Want to first start by saying thank you to this community as it’s been tremendously valuable to me.
So I have a battery pack out of a hoverboard. Its advertised at 36V 4400mah. What would be the cheapest way to accurately measure that it ACTUALLY has 4400mah? There is only an XT60 connector popping out of it and I’d rather not rip it apart and test each cell …
Currently I’m charging it up with a cheap 42V charger with an XT60 connector on the end of it and its working great, but it obviously can’t tell me the capacity.
Could I theoretically … discharge it to a known voltage (like 30 Volts) and then assume that my charger is charging at 42V 2A consistently, and track how long it takes to charge to 42volts? And calculate from there?
I’m hoping not to drop $135 on an iCharger 1010B+ …
Would love to hear your thoughts, thank you very much!
