Caution:
1.LiPoly batteries must be charged carefully.
2..The basic process is to charge at constant current until each cell reaches 4.2 V;
3..the charger must then gradually reduce the charge current while holding the cell voltage at 4.2 V until the charge current has dropped to a small percentage of the initial charge rate, at which point the battery is considered 100% charged.
4.lithium polymer batteries can be stored for one or two months without significantly losing charge. However, if storing for long periods,Please discharging the battery to 40% of full charge.
