Lithium polymer battery, rechargeable batteries. generally composed of several identical secondary cells in parallel to increase the capacity of the discharge current, and usually are available in series "packs" to increase the total voltage available. One element of Li-Po has a nominal voltage, loaded, 3.7 V. Never discharge a battery below 3.0 V per cell. slow loads for longer life cycle is recommended for batteries of more than one item is required balancer charger. If no use in a time period, it is necessary to leave them loaded on 75% capacity.
