Determine the amp hour rating of a home made battery pack

If you have one series string and that happens, the pack voltage drops and you have to replace that one cell. Inconvenient, but still the best of all scenarios. If you have multiple strings in parallel, current can flow backwards through the string that contains the bad cell, potentially damaging the entire string.

High-voltage EV battery packs: benefits and challenges. More voltage ...

As with most things in engineering, arbitrarily increasing the pack voltage isn''t unequivocally a good thing, and that''s even without invoking a reductio ad absurdum argument (e.g. if 1 kV is better than 100 V, then 10 kV is better than 1 kV, etc.). Still, there are some benefits to increasing the pack voltage, and the most obvious is that less cross …

Negative voltage on AA battery

Last night I pulled the battery holder out of a toy RC car to test the voltage with my meter. The pack has 4 AA batteries. The combined voltage at the terminals of the pack was well under 1 volt,... $begingroup$ I had this happen with three alkaline LR6-AA batteries in series, only it happened to TWO of the three. ...
