would this battery work with a 60A ESC and outrunner consuming max 50A? I am not sure on the 30C and I clearly prefer LiFePo vs LiPo... thanks!

This should be capable of giving at least 120A constant...

I bought two packs in late September. The following months have been very windy so I have only flown a couple of times. Today on the first flight with these cells for the season they balloned. Capacity was less than 3700 mAh, despite balancing charging yesterday. Max current 55A, they have never been emptied below 3700mAh. Recycling!

Hi, Anyone know what is the wire gauge size with this pack? Can it be use with the xt60 connectors? Thank you.

nominal voltage for LiPo is 3.7V (1s), for LiFePo it's 3.2V so on 8s it's 29.6 vs. 25.6V biggest advantage for LiFePo is longer life IF you don't overtax them In your scenario: 8s1p, 4.2Ah *30C constant is 25.6V x 126A = ~ 3.2kW, burst power 4,3 kW You might get away, but for me it would be too narrow a margin.

I forgot to mention I'm in Canada and the excessive charges are for across border shipping.

You need to check the voltage of these pack as soon as you get them!! Two times I ordered this, four packs each time. one pack was 1v.. essentially dead, when I got it. One pack was not balanced and the other 2 were OK... same thing two times...

Tras 3 cargas uno de los elementos ha caido, no digo que sea mala pero a mi no me ha dado un buen resultado.

Discharged at 5, 10 , 15 and 20 amp until 11 volts. 5 x each Performed ok charge via turnighy ACC6 Monitor with fluke meter All displayed values close enough for me. Do not know self discharge rate yet. Dunno how it'll go discharging at 30 C or~ 120 amp. I'd guess the batt wire is good for 20 amp continuos, Battery gets slightly warm to touch during 20 amp discharge or around 20 minutes to flatten. 50 amp continuos may be a big ask. It'll be spot on for my non flying application.
