This is a new type of battery to try. The finish is good and the price is very advantageous. After only a few break-in flights, I am satisfied. It responds well to requests and does not heat much, although I did not shoot too much. For reliability it will be necessary to see over the duration and lot of flights..

In the item description, the Power Plug is "XT60", but the item that arrived was "SY 60".

Fit nicely in the battery compartment of the devil 380. Voltages were very even 3.84 ~ 3.86 range. I was initially disappointed as I thought I had to change the connector as it does not come with an XT60 connector but a sy60 connector. Fortunately, I googled sy60 before replacing the connector and it is compatible with xt60. Seems to fit ok, certainly easier to unplug the battery.

I have already bought 2 batteries like the one. I am very satisfied after about thirty cycles of charge. They do not heat, they do not swell and give power when asked.

I had two of those for my twin EDF plane with a current hungry EDF at 65 Amps at full throttle . the internal resistance was 2 mohm per cell which fits graphene technology . punch was excellent . slightly warm at 40 degrees after flight ( flight time 4 min ) . one battery performed well and still doing so and one battery shorted one cell ( did not bloat or leak just found it at 0 volt after a week in storage at 50% charge ) so I removed it now I have a 5S graphene battery. so I guess it's good if you are lucky . I will definitely keep buying those as price/performance is unbeatable.

can give upto 1600 watt 75 A by 21 V from the begining. very good form factor. Now more then 300 charge and discharge times and capacity near 2200 - 2100 maH. Low internal impedance 3-5 millyomm per sell. Never temperatura higher then 40 C during discharge under heavy load. Can be charge easily with 2-3 C. Working OK in RUSSIA with outside temperatura mines 10-12 C. Till now no weak points. WAITING for 3000 mah with good form factor.
