iFlight FULLSEND 6S 850mAh 95C Lipo Battery XT60 Connector for FPV Drone Racing

I ordered 4 full send 6s 850mah batteries. 3 of them where in the storage voltage range. One was at an average cell voltage of 4.15, which means it left the factory at full charge and degraded over time as it sat on a ship, a shelf, then a shipping truck. Leaving a lipo above storage for more than a few days damages the cells, to what extent, I won’t know until it dies in the coming days, weeks or month. Disappointed.

Capacity is as advertised, I get 855mah. Weight is also as advertised, which is the main reason I got them. C rating seems a bit overrated at 95c. I do see voltage sag at full punch of .4V, that said I am running 350g AUW and never actually need to punch it past 70% so it doesnt matter to me.

terrible quality, i expected more from iflight. some bad out the box. Others lucky if they last a couple months

These 6s 850mah are fine, reasonable power on the punchout. They are about 20g lighter than the GETFPV Xilo 6s 850mah, though they have 16awg leads on. My only issue is the cells start wiggling in the heatshrink after a few cycles, apparently the shrink is not tightly holding the cells together.

Not what I expected from Full Send but the 2nd cell was 3.37 and the rest of the cells were 3.67. I checked with 2 chargers to double check.

I had 2 of these and both dropped a cell 1-day apart. I now run one as 5s and discarded the other bc I didnt know how to remove a cell from the middle. They felt good and I was ready to start praising them, and then all of a sudden a cell was gone. Unfortunate.

Works really good for the diatone 369. The battery cable is not to long which is great. Overall I recommend this battery.

Same great experience you expect with iflight
