A look inside to see how the newer style Ryobi 40V Lithium battery is built. Tips on repairing

Exactly what I needed. Thanks.

Hey no problem!

Your disclaimer TELLS ALL........ "I am not a battery expert. Lithium batteries can be very dangerous so I do not recommend taking them apart"

Welcome to America where people sue because their hot coffee they wanted was hot and they spilled it on themselves.

.........How can you say there is 42 volts on each side?????? You can clearly see how the batteries are in parallel on each side = 20 + volts on each side YES. ALSO I can say you had the balls to cut the circuit board the way you showed it....... YOU ARE VERY LUCKY THE BATTERIES WERE DISCHARGED!!!

You said there’s 20 V on each side and the two sides are parallel. If that were the case, then the battery would only be 20v and double the amp hours of a single side. The only way to get 40 V out of two different sides of 20v is if the 2 sides were ran in series with each other. Each side is not 20v though. This pack has 10 batteries on a side. 10x4.2v(per battery) = 42v. So on each side is 42 V. The two 42 V sides are ran parallel to each other so the voltage remains at 42 V but combines the amp hours of the 2 sides which doubles the amp hours of battery pack.

@@freshmaker5 Manuelruiz is correct. 20+ V each side. Connected together in series for a total 40+ V.

none of the fixes work!
