lrp says specifically that lipos are not compatible with the rx. but i bet that is to protect them in the case of someone smoking the esc and it turns out the culprit was a lipo battery. I have been running the traxxas stock esc for a while now on lipo and it has no cutoff and i have had no trouble with the packs. i should probably get the novak external cutoff but it is $35 and it may be better to just save the $$ to get another BL combo.. what to do... thanks for your input.
