Ok, so I'm running a Kraton 6s EXB and it's developed a weird problem. Lipos keep "losing" cells.
The electronics are a Hobbywing max8 ESC and Corally Kuron 825 2050kv motor. Lipos that have lost cells are 2x Zeee 3s 60c 6000mah and 1x gens-ace-r-spam bashing 3s 50c? 5500mah.
The first battery I noticed this on was a Zeee, it was when I went to charge it and the charger only recognised it as 2s, tried different chargers and battery checkers and they all showed the same. I put this down to bad luck and discarded the lipo. Took the rig out that day with the gens-ace-r-spam and after about 30 seconds it to failed in the same way, I put this down to coincidence and bad luck. Now here is the weird part, had the rig out yesterday and the run times were significantly shorter. Checked the lipos after the run and one cell in another Zeee was down to 2.1v and by the time I got home the cell was gone, charger not picking it up.
3 lipos failing the same way can't be coincidence so I'm suspecting a fault with the max8.
Another thing that might be connected to this. The original Hobbywing 2200kv motor failed a couple of months ago (magnet shattered), replaced that with a racestar 1700kv motor that was lying around, that failed too a month later (overheated, windings burnt). The Kuron motor is brand new and is performing well. Does this sound like all roads point to the ESC?
Does anybody have any insight or similar experiences?
