-They don’t use a Lithium compatible ESC
-They can discharge up to 25C
-Cell voltage is 3.3v, so a 3s pack is 9.9v
-They can fast charge up to 3C (9.9v) in just 20 minutes
-They don’t have to be balanced as often as Li-Po’s – every 12-15 cycles
-Voltage is stated as increasing during discharge, power is maintained throughout the flight
-They can be used in paralled up to 4600mAh
The 3s pack pictured weighs around 230g and measures 81mm long x 70mm wide and 27mm high. It has a working current of 20C (46 amps) a max current of 25C (57 amps) and a burst current of 50C (115 amps). The balance plug is JST-EHR.
We’ll be bringing a mini-review in RCM&E soon and in the meantime I’m going to be flying the pack pictured above to see how it fares. Check out the forum thread below in the meantime.
