Was there an older version of the XL 5 that did not work with Lipos? I found an XL5 on ebay that said it works but "no lipos"
I presume that even if it did not have a LVC it would still work with lipos because the max voltage is almost the same as a fully charged Nimh.
It was $10 plus shipping so I bought it for my old mechanical speed control replacement. Don
