Description
All Li-Ion packs listed are build specifically for Flight Comp in the USA. Packs feature spot welded nickel tabs between cells and all wires are soldered to nickel tabs. This is a much more robust solution then soldering directly to the cells. These tabs make our packs more reliable and do not introduce the heat of a soldering iron directly into the cell. Packs are hand checked and charged to 7.9V insuring years long shelf life.
These 5000mah Li-Ion packs are perfect for large models such as scale sailplanes, or 4m+ slope models. Or any large RC model.

Charging:
Charge the batteries with standard 2s li-ion programmable chargers. If your charger doesn't list li-ion then 2s lipo program is fine. Charging format is the same constant current then constant voltage in either case. You can charge at up to 5amps. Should come off charger at 8.4v. Never discharge below 6v. Long term storage is best at 7.4v (standard lipo storage charge). Regardless of charging program battery should never exceed 8.4v under any circumstances. Balance charge every 5 cycles.
