I have 3 packs of GP 3700 cells, none of which will take more than 3200mah when charged at 5amps, or output more than 2600mah when discharged at 20amps.
So I have disassembled the worst pack. I have then charged (5amps) and discharged (20amps) 3 of the cells individually. Below are the figures
Charge : 1351mah in 971 seconds
Discharge : hit cut off voltage (0.9v) within 10 seconds
Charge : 1288 mah in 928 seconds
Discharge : 209 mah in 40 seconds
Charge : 1289 mah in 929 seconds
Discharge : 271 mah in 49 seconds
Are these typical ? If not, what level figures for charge and discharge should I be getting?
