Products with triple protection
1.Overcharge protection circuit
Protection IC detects battery voltage when the voltage reaches 4.25V (assuming battery
overcharge point is 4.25V) then start overcharging protection ,MOSFET switches to cut off,
and then cut-off charge.
2.Over-discharge protection circuit
Protection IC detects battery voltage when the voltage reaches the discharge voltage detection point
(assumed to 2.75V or 2.55V) will start over-discharge protection, the MOSFET switch cut off,
turn off discharge.
3.Short-circuit protection circuit
When the discharge current is too large or short circuit conditions, protection IC will start
over-current protection (short circuit), increases the internal resistance of the battery to
stop battery discharge.
