Review on Li Ion Lithium Battery Charger Protection by Kristen Rohr
something shorted.
I connected everything correctly as shown in the diagram for the battery. Checked voltmeter and showed 12.55V. when i tried to charge with a 12.6, 1 amp charger something shorted and the voltage dropped to 8.36 at first, then i checked the soldering and somehow shorted again, lost another cell and now it just shows 2.70v on. this was only the first board, i will try another one but it looks like they are all going broke.
- Note 4: When connecting three batteries in series, make sure the voltage of each battery is the same. If not, fill each battery separately and then use them one by one. In the discharge test, a group of batteries whose voltage drops more rapidly is called a bad battery.
- Some errors
