If you are looking for a good battery for your 4pk then look no further! For a weekend racer like me you might only have to charge this thing 1 or 2 times a season. I put almost 10 hours on my transmitter before charging it and only put 850mah back in. Great battery and great price!

ProTek RC LiFe 4PK/4PX Car Transmitter Battery Pack (6.6V/2100mAh)
Got one for my futaba 4px has worked great so far have used it for 6 hours straight and hasn't moved between 6.5 and 6.4 im new to this type of battery and almost sent it back. After i charged it to 7.2v i unplugged it and voltage dropped to 7.1 then 7.0v i put it in my radio set the battery option for the life battery in my radio. And noticed the voltage kept dropping. I looked around on the net didn't notice much info about this. The voltage dropped down to 6.5v after about 5 minutes. I contacted amain tech and was told this is normal and it will take along time before it drops Again and it was doing what its supposed to do stabilize around the 6.6v level and that 6.5 to 6.4 is normal. its just the chemistry of the Life battery. So far im very happy have got alot of hours on the radio over 5 hours of just goofing in options along with 6 hours of run time running my car and its still at 6.5 to 6.4v great battery Im happy with my purchase.
