Dinogy offers a GRAPHENE with the 65C series ( DO NOT believe other brand #39;s C Rates ) This new series is the perfect compromise between power and price! These batteries still use Graphene 2.0 technology that has proven itself on the ULTRA and GRAPHENE range These batteries can provide power still very important but without adding too much grams and lower cost! ;) An interesting alternative for your racing machines because the ratio weight / power / price unbeatable .
