From Hobby king trying to get the right combinations is really annoying. It important to remember when working on batteries combinations:
in Series you are doubling the voltage while keeping the same (amp hours), and in Parallel you are doubling the capacity (amp hours) while keeping the same voltage.
I want the most amp hours so an 8AH would be best as that is the highest amount which seems to be easier to get to the voltage requirements.

I'd only need two of these but always out of stock.
http://hobbyking.com.au/hobbyking/store/__23684__zippy_flightmax_8400mah_3s2p_30c_lifepo4_pack_usa_warehouse_.html I would need 5 of these to get 50v @ 8AH 4kg battery for $325 for LIFEPO4
Capacity: 8400mAh
Voltage: 3S2P / 9.9v
Discharge: 30C Constant / 40C Burst
Weight: 772g (including wire, plug & case)
Dimensions: 147mm x 52mm x 53mm
cheaper charger

I could have 3 to get a 55v for a 5 ah at 2kg or 6 to get to a 10 @ 4kg
Capacity: 5000mAh
Voltage: 5S1P / 5 Cell / 18.5v
Discharge: 20C Constant / 30C Burst
Weight: 640g (including wire, plug & shrink wrap)
Dimensions: 147x52x43mm
Would I need two 8s chargers? Controller experts help please. I want to change my battery but am scared I might fry the controller. It's a "Crystalyte 36V-48V 40A digital controller
12 Fet (4110)" and the current battery is 48v10Ah LiFePO4 Headway 38120S cells BMS Rated at 40A Continuous, 60A Peak. The 5A charger output 58.4VDC. Fresh off the charge it rests at 58v and slowly goes down to around 52v underload between 50-47v etc as she goes down... I want to get two of these in Paralel so 29.6 x 2 = 59.2v
http://www.hobbyking.com/hobbyking/store/__19158__Turnigy_nano_tech_5000mah_8S_65_130C_Lipo_Pack.html will the controller handle it? I really don't want to buy another controller. And I really don't want to go to a 44v combination of lipo. http://www.hobbyking.com/hobbyking/store/__12104__HobbyKing_ECO8_150W_7A_8S_Bal_Dis_Cyc_Charger_w_acc_.html
