Safety Warning All Lithium Polymer (Lipo) batteries REQUIRE a Lithium Polymer Charger set by the user (you) to correct number of cells and charge rate of approximately capacity x 1. All charging should be in a firesafe container or outdoors away from flamables. Fires are rare but they do occur with user charging errors. Make sure your only loss is your battery and not your life or property.

Balancing every 5 to 10 charges is reccomended. Also be sure to repeat balance procedure when new or after any battery abuse/overheating or repair. Puffed cells are caused by charging to over 4.2v per cell, charging unbalanced packs, discharging over max C rate or otherwise abusing battery.

LiPo Batteries 3701mAh and Up

The highest-capacity packs live in this category, intended for bigger electric airframes, high-power setups, and pilots who want longer flights or heavier current draw. Higher capacity brings more stored energy, and the trade-off is added weight the airframe has to carry.

High-Capacity Packs

Radical RC K6 series packs anchor the range, with 4000, 4200, 4500, and 5100mAh options in cell counts from 2S up to 6S, so you can set voltage to suit a demanding motor. An Onyx LiPo pack is offered here as well for another capacity and voltage choice.

Selecting from this group means balancing capacity and cell count against the current your motor and speed control can handle, plus the weight and space your model allows. A pack matched to the system runs cooler and lasts longer than one pushed past its rating.

Compare the high-capacity packs below to fit one to your larger electric aircraft.
