Guys got some 3S Transmitter lipos for sale, I have 6 in total for sale. They have also been posted on other forums so it will be on a first come first serve basis.
These are a great replacement for your standard AA's and will last longer too, plus they are rechargeable. Smaller than a AA Tx Battery tray in flat formation so should fit most Steerwheel Transmitters. Fitted with a Male Futaba connector.
Comparing against AA Battery Tray and with batt tray removed.
All have been checked, are in working order.
Specs - 3S (11.1v) 10C Discharge 2200mAh
Dimensions - 110 mm x 40 mm x 12mm
Looking for £22.50 posted - Hard to come by nowadays due to popularity and the turnigy ones are always out of stock.
Any more questions feel free to post on here or PM me.
