Basic Lithium Polymer Battery Guidelines
By purchasing this battery, the buyer assumes all risks associated with lithium batteries. We assume no liability for failure to comply with these warnings and safety guidelines.
Lithium Polymer batteries are volatile and can be very dangerous if mis-handled, stored, charged or discharged improperly. Failure to read and follow these instructions may result in fire, personal injury, and damage to property
Store below 80F and above 40F whenever possible (not in direct sunlight). Never store or charge a battery pack inside your car in extreme temperatures (100 F and above), since extreme temperature could cause fire. Use caution to avoid puncture of the cells. Puncture of cells may cause fire.
Charge before using. Use only chargers made specifically for lithium polymer batteries. Before the first charge, check for damage to the connectors, wire leads or any other abnormality. Please check the voltage of your pack. Packs are shipped from the factory at the following voltages: Never charge Lithium Polymer batteries unattended.
2 cell packs – 7.6 volts +/- .5 volt
3 cell packs – 11.4 volts +/- .5 volt
4 cell packs – 15.2 volts +/- .5 volt
5 cell packs – 19.0 volts +/- .5 volt
You must select the charge rate current that does not exceed 1C (one time the capacity of the battery, unless otherwise noted). A higher setting may cause fire. This chart is calculated at 1x capacity of pack. Generally speaking, charging at even lower rates will extend battery life.
800 mAh: Charge at or below 800mA
1500 mAh: Charge at or below 1.5 Amps
6000 mAh: Charge at or below 6.0 Amps
If at any time you witness a battery starting to balloon or swell up, discontinue the charging process immediately. Disconnect the battery and observe it in a safe place for approximately 15 minutes. Continuing to charge a battery that has begun to swell may result in fire.
Charging NiCd/NiMH
GP Cells 1100mah, Intellect 1400mah and Elite 1500mah Packs
For best performance, charge these cells at 1.5 amps or less. These cells can be charged at 2amp, but they must be watched to make sure they do not get too hot.
Transmitter, Receiver Packs and Runtime 2600mah Packs
2600mah packs will work the best when charged at 1/2 amp. With these packs you are looking for runtime not punch. A 2600mah pack will take about 5 hours to charge if it is completely dead. If you charge a transmitter pack this way it should last you at least 2 days of racing with no trouble at all. A 2600mah receiver packs should last you ALL DAY when charged this way.
1400mah and 1500mah Receiver Packs
These packs work best when charged at 1/2 amp or less. With these packs you are looking for runtime not punch. A 1500mah packs will take about 3 hours to charged when completely dead.
Some charge should be left in NI-MH cells if you don't plan on using them for more than a week. Some performance will decrease after long periods of inactivity. The packs should be cycled a couple of times after a longer period of storage. Cycling packs are done by charging and then discharging. Packs should be discharged at 2 amps.
Charging/Discharging: Charge your lipo battery pack at 5C or less on a lipo approved charger only. If you choose to charge at any rate higher than 1C, you must use a balance charging system similar to the Hyperion chargers offered here at MaxAmps.com. Otherwise you risk your pack becoming severely out of balance over time, which in turn will significantly decrease the lifespan.
Ex: If charging a 4000mah lipo pack at 1C, you would be charging it at 4 Amps.
Ex: If balance charging a 4000mah lipo pack at 5C, you would be charging it at 20 Amps.
