1. Lipos Battery Charging:
Based on the structure characteristics of lithium-ion batteries
The maximum charging voltage should be 4.2V. Not overcharge, or positive electrode of lithium ion took too much, and discard the battery.
The higher charge and discharge, constant current, constant voltage charger for use to recharge.
Usually constant current charge to 4.2V/after transfer to constant voltage charging, when the constant voltage
charge current below 100mA or less, should stop charging.
Charging current (mA) =0.1~1.5 battery (1350mAh battery, the charging current can be controlled between 135~2025mA).
Normal charging current can be selected at about 0.5 times the battery capacity, charging time is approximately 2-3 hours.
2. Lipos Discharge:
Due to the internal structure of lithium-ion batteries, discharge lithium-ion cannot be moved to the cathode
the part must retain lithium ions at the cathode,
To ensure that when the next charge lithium-ion can easily embed channel. Otherwise, the battery life will be shortened. In order to ensure that the discharge in the graphite layer after that leave some lithium-ion,
It is necessary to strictly restrict the discharge end minimum voltage
which means that lithium-ion batteries cannot discharge.
Final discharge voltage for the 3.0V/section, must not be less than 2.5V/.
Battery discharge time (hours) = battery capacity/discharging current.
Lithium-ion battery discharge current (mA) should not exceed 3 times times the battery capacity
