Lithium Polymer technology. (Li-Po) These batteries must be used with Lipo balance chargers specifically designed to charge these types of batteries. Low voltage cut off circuitry is also required. These packs should only be considered by experienced racers.
 

The best cell you'll find in its price range! These packs are pre-assembled and only available as shown. These cells have excellent durability and good power. The 4200's are the best choice when using less expensive chargers. Note: These cells are not intended for extremely high current draw applications. A 7.5 turn or equivalent brushless motor (350 watts) is the highest horsepower recommended for use with these cells.
 

Our ENER-G 4600 V2 is by far our highest performing cell, with a new formulation for incredible power and lower self discharge than our previous version. These cells should be charged with equipment that is designed specifically for ni-mh cells and with an adjustable peak detection feature!These cells are rated for 2.5 turn motors or brushless equvalent (730 watts)
 

These cells have very good power and the longest run time. These cells should be charged with equipment that is designed specifically for ni-mh cells and with an adjustable peak detection feature! Due to the extremely high density of these cells the self discharge rate is fairly high so keeping a partial charge in the cells at all times is essential! These cells are rated for 4.5 turn motors or brushless equvalent (550 watts)
