Exactly the batteries I needed for my RC boat. Thanks to the dealer and or vendor

Battery DOA will not charge out of the box

Garbage. Ill charge the batteries on a friday, go to a place to play with my rc's on sunday and the spektrum dumb batteries are dead. These are $80 trash. Nothing smart about them. Brand new 2200mah, never used, charge it and it had a dead cell.

Battery failed after less than 10 cycles, will not take a charge. Only every charged on a Spektrum Smart charger.

About 5 charges on it and all the cells went flat have only charged it on a spectrum charger junk batteries

packaged very well , so far working good , only have 2 cycles on it at this time.
