I used some custom made 5000mAh 30c packs made here in germany. Not sure which cells they're using but they're pretty good... never ever rose more than 3-5° above ambient.
Yeah after two and a half months of waiting i got mine today installed it calibrated it and then when i was setting my steering trim..... it turnerd off. now NOTHING AT ALL
Still links up with the castle link but that is it. Crap now i have to wait another month for it to be repaired.what a disipointment
