The Turnigy 2650mAh Transmitter pack fits snuggly into any Futaba or Jr radio which uses a 4x4 AA cell battery configuration (see image). It includes discharge plugs for both JR, Spektrum plus other radios. It's built with a low C-rate Long Life LiCo Formular which isn't like a standard LiPo. It retains voltage for months on end without need for a storage charge so you can store your radio and fly once a month and not have to worry about discharging or recharging your pack.
With a capacity of 2650mAh this lipoly replacement for your old NiCD or NiMH will last four to five times longer. Probably the best advantage with a lipoly transmitter battery is that it will give a true voltage reading from start to finish which means you can say goodbye to the days where you thought your Transmitter was fully charged at home, only to find the voltage drop off rapidly when at the field.
Right here on this website, go to chargers and accessories.
As a sugestion i would recommend the hobbyking eco 6 80watt or the cheaper imax b6. for the second one you will need a separate power supply.
Just looked at the DC4S you should just plug the balance plug in to the charger to charge it. have you overdischarged the pack (left the transmitter on?) if so, the charger will not sense it has a lipo plugged in and start the charge cycle.
best practice is not to let the lipo voltage drop to below 3volts per cell...
you may, may possible recover the pack if you plug into a nimh transmitter charger for 10 - 15 mins only.
but the pack is most likely dead as lipos do not like to be deep discharged.
on my tx's, I have a 10 min inactivity timer that beeps if the sticks aren't touched for 10 mins... but I have a nimh pack in one and a liion in the other...
Nice battery. Fits perfect in my airtronics RD 6000 and 8000. As well as my graupner mx24-s.

The battery came with the output polarity reversed. Damaged my Transmitter and now HobbyKing does not want to stand behind their product. If I could give this battery negative stars I would, along with their lack of support for a manufacturing defect. Hobby King is off my list of places to purchase.
