Need Some Advice on Supermaxx setup Please.

[Smurfy]

Well about 2-3years or so have passed since i last ran my Supermaxx:)
Its a 18.97kwf Controller / Hacker C50 setup running on 14 3300 NiMh cells. Unsurprsingly the batterys are rather dead after being left for that period of time without any care, a number of charge/discharge cycles havent helped much.

Im currently considering my options, im really not intrested in spending a fortune on this project as i've proven i dont use it anywhere near enough to warrant the huge expense i originally put out.

So im looking at replacing the batterys, possibly/Probably with LI-PO batterys.
What are my options?
All comments/thoughts welcome.

I have a Great Planes Triton Charger which i belive handles LIPO, will this manage the newer LIPO cells?
