Besides myself and Cart123, you are the only other I've heard to run 5S yet, so its very much R&D at this point. Did you but in a voltage cutoff? My only thought is that perhaps with your large truck and big 1515 Neu motor you end up pulling a lot more amps and lose voltage below the cutoff. Or its just too much for the esc... I would think the 8Ah batts would be better as far as voltage drop, but maybe they are lower C batts vs the 4000s and don't handle the lg load as well. Perhaps its even a bum cell in the 8Ah pack... :032:
Cart123 actually ran more voltage (6S M1 cells) but really only had thermal issues IIRC, so I don't know if its raw voltage. We're playing on the edge of the edge w/ the equipment, so there are no guarantees. Very nice conversion tho, drives great.

Thanks for the input - It is now running with 5s 8000mah:027: I suspect one of two things. I am running a 2s and 3s in series. The 3s is one of the newer Maxamps "HV" packs. The 2s was a MaxAmps pre-HV pack. It is now working after replacing the old pack with an HV pack. It could be that the older pack was not up to the task or that I just forgot to charge the older cell before hooking it up:007: Most likely the latter. I hope to get vids up of mine with the 5S soon.
