How to charge a salvaged Li-ion battery pack? Answered
I've recently salvaged a 11.1 V Li-ion battery pack from an old laptop battery.
Voltage : 11.1 V ( ~ 4400 mAh )
Cell : 6 x Samsung 18650 22f cells ( 3.7 V and 2200 mAh )
Arrangement : 3 packs in series , each pack having two cells in parallel
The charging circuit is intact. How should I safely charge them?
I'm well aware of the hazards related with improper charging of Li-ion batteries. Can anybody please suggest some ways to charge it ? any tips ?
I need to know the proper procedure to safely charge (and discharge ) a Li-ion battery and what does a "protection circuit" do ? Thanks !
