thanks for that question, most people fix their batteries with a reading lower than 7.4 so if in a battery you se a lot of 7.4 7.3 7.2 7 7 7 and one module reads 6.4 that might be the culprit but I've seen modules reading good like a 7.8 and then when the battery is at high load they are weak because they don't hold enough capacity, usually I do the recondition of 3 discharges/charges and the module tells me the real nature that's how I can make a long lasting battery pack but for easy and fast fix just try to identify the lower voltage one, but like I said before sometimes works and sometimes don't , later I will post a video how to do the discharge and charge.

Yes fixed the battery problem solved

Hey thanks for asking do you think you can give me a sub code like P0B3D-123

Usually the middle ones are the most affected by the heat and deteriorate faster I replaced those because people buy ebay modules and unfortunately ebay sellers just cheat people with old modules.
