I thought about this and even bought a 3 cell battery and balanced charger - then I realised the dangers of LiPo and decided against it in favour of 10 2.5AH NiMH cells in a 5 over 5 holder. This fits in fine in place of the lead acid, is a lot lighter and can be charged quite easily with minor modifications to the K2 battery system.
I am interested in the results though as I still have the LiPo and balanced charger. Mike Johnny Siu wrote: > > Hello Group, > > 3.7v 3300mAH Li-Po cells are cheaply available locally.
