no more care than nimh is needed. cost is cheaper overal as they dont loose performance

we have been testing in d4 and b4, adding weight helped, but im sure somone will find the sweet spot with a lighter car

hell
please dont charge them at 20c a 5000mah pack would mean charging at 100 amps!!!!!!!!! charge rate of 2c is the max!

What ongoing & long term disadvantages are there? Is punch decreased? Do motors run hotter? Do they damage easy from hard landings? Is the life of them short?

punch stays capacity drops, nope you have seen by prototype lipo cells with no hard case and my big accidents at worksop, no damage. nope trakpower ohave been amazed at how long packs are lasting in cars, as we use em a bit and top em up, they were looking at helicpoters where they do a full charge/discharge at full load. rcracehat has a pack with well over 100 charges and its still the same as new and was only recently balanced, when it was it took a few minuites to pull it back into balance.

Not allowed at BRCA 10th Off road National and Regional level, rule states "max of 6 C type cells" needs to be changed and samples submitted to the electric board for approval.

insurance and use under the BRCA is fine, just not at sanctined meetings that dont allow them
ie there meetings that say only 6 cell they can not be used, any other meeting that wants to allow them can do and is covered by the brca
TC have allowed them in the uk
as i understand the brca will have a foot print, no hieght or capacity size, and they must be in a hard case. i dont believe they will mention stick only
