Product Usage:
2 strings of nickel cobalt manganese, lithium cobalt oxide, lithium manganese oxide rechargeable batteries
2 series lithium polymer rechargeable battery
Notice:
1. During connection,pay attention to input/output voltage,load current using condition, and make sure that board power consumption will not surpass tolerance consumption
2. When connect with battery,it may not discharge;in this condition,continuous charging can let it restore to normal operating state
3. When overcharging battery and overdischarging battery are mixed up,it will become charging and overdischarging state, both of them cannot perform charging and discharging
4. Although this protection board internallt installs anti-static protection circuit, please don’t force too high static electricty on protection board
Package included:
1 x 2S Li-ion 18650 Lithium Battery Charger Protection Board
