Hi

My 36v lifepo4 on kudos is getting towards 4 years old now, is the voltage of battery an indication of deterioration. Mine after a week from full charge is sitting at 42.7v.

My booster 2cell battety zippy1300 decided to give up after 15months so looking to get another, i see there is aTurnigy nano-tech 12800mah 2S 40~80C Lipo Pack as a replacement, has anybody got one of these, any feedback is welcome please.

How many lifepo cells safely for ku65 controller and 8fun motor, is it 11 or maybe 12. ?

Thanks for any help.
