About Lithium Polymer Battery
Q: How does charging current relate to capacity?
A: First of all, make sure of the rate for a given length of charging and use the following rule: Amps = Capacity / Time to Charge. For instance, to charge a 1200mAh battery in 20 minutes requires a current setting of 3.6 amps: amps = 1200mAh / .33 hours = 1.2Ah X 3 hours =3.6 amps. The same rule can also be reworked to determine how long it will take to charge a battery at a given current: Time to Charge = Capacity / Amps. So, the time it takes to charge a 1500mAh battery at 5 amps is 18 minutes: Time to Charge = 1500mAh / 5A = 1.5Ah / 5A = 0.3 hours = 18 minutes. The charging process is not totally efficient; some of the energy is lost as heat, and the charging takes place a little longer than this.

Q: How can I make certain my packs are fully charged?
A: GWS or E-flite peak chargers automatically do this. If you don’t have a peak charger, well provide the way to monitor the charge yourself. Youll simply stop charging when one of the following things occurs: either the pack starts to get warm or the charging voltage starts to drop. Warning: if youre doing a manual fast charge (by watching the temperature and/or voltage yourself), pay attention. If the batteries get too much charge, they will overheat, and that could damage or even destroy your batteries.
