I was wondering about upgrading the batteries that came with my Futaba 6EX, both for the transmitter and receiver (increasing the mah's). Anyone know how to go about doing this, and can recommend a good place to get batteries?
I picked up four TX "Rhino" battery packs from Unitedhobbies.com aka HobbyCity.com.
They are rated at 2750mAh and feature both JR and Futaba connectors.
Cost about $18.00.
I've been using them for several weeks. Typically I charge my TX's on Friday and don't worry about them over the weekend....
My timer indicates that I've had the TX on for well over 12 hours w/o even dropping to the first tick mark for normal NiCD/NiMH batteries.
I keep my now "old" 1800mAh TX packs charged up as spares...
I've been quite impressed with their Zippy and Rhino series.
I've purchased four 3700mAh 20/30C 14.8v LiPo packs for about $68.00/ea.
They test out around 3850mA and do not get warm when discharged at 20C.
I've also seen several US vendors selling similiar TX packs.
