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 1001 to 1800mAh
This capacity band is a workhorse range for electric flight, well suited to park flyers, sport models, and smaller aerobatic aircraft that need a useful flight time without a heavy pack. The batteries here span a range of cell counts so you can match voltage to your power system.
Packs in This Range
Options include Venom Fly and Venom Fly Graphene 1300mAh packs in 2S and 4S, along with Radical RC K6 series packs from 1800mAh 2S up through 1500mAh in 5S and 6S configurations. Higher cell counts raise voltage for motors that call for it, while the 2S packs suit lighter, lower-draw setups.
When choosing, weigh capacity, cell count, and discharge rating together against what your motor and speed control expect and the space your airframe allows. A pack in this middle band often gives a good trade of flight time against weight for everyday sport flying.
Browse the packs below to find the capacity and cell count your model needs.
