Its really my fault, I’ve had those for a few years I used them to power a fish finder on my kayak and I shorted one one day damaging a cell. It balaced up ok but underload on the eskate it was discharging to 3.2v while the other 3 cells were at 3.5v so best not to be using it anymore… don’t want a board fire 
Ah ok, I thought they were new
Although one of the 2s Turnigy Nano Techs I bought the other day arrived with less than 3 volts on both cells, I contacted hobby king and they sent me a new one straight away so I have nothing to complain about with Hobbyking.
Got the 12s wired up today. Took it for a short circuit of the neighborhood. Its scary at the moment 
can putt around but a little slip of the thumb on the nano x and could easily go horizontal. I will have to tweek the current settings.
Its running sensored foc so with some subtle precision movements on the remote and i can crawl away from a dead stop with ease.
So I could play around with settings for forever and a day but if any of you with experience on setting up dual vescs on sensored foc could give me some input that be great? Specifically <egzplicit as you have alot of the same gear.
Have current settings at 40, -40, 25, -12. Seems pretty good at that, more than I can use at this stage.
Did a circuit around my local streets tonight and did some sums on range. Approx. 26km i calculated for 4.15v to 3.5v per cell. Does that sound about par for a lipo 12s pack at 10amp hour 30C?
Yeah that would be about right for a pnuematic setup, your averaging 17Wh/km which is quite good. With street wheels you would get close to 40km
Thanks Pat
Been a while working on this but I got an enclosure modelled to house the dual foc box aluminium Servisas enclosure… haha its an enclosure for an enclosure. Sending it for printing in ABS.
Yeah my print turned up, thought it came out pretty good, a little clean up but I think it will do just fine.
I will have to use some Sugru to seal up some gaps around the aluminium enclosure and I’m using neoprene tape as a gasket against the board.
Won’t be water proof, but certainly water resistant and splash proof.
Battery enclosure with lid and xt90 anti spark switch, send for printing! not too long now to have everything for a full assembly!
Hi all, been a busy 2018 and I never spent enough time finishing off this build last year.
Had some holidays so was able to get the enclosures onto the board and have it up and running.
Have made a slide on the lid to house the xt90 anti spark connector. Works well!
Use a piece of braided fuel line to run power to the controllers. Keeps it flexable
Batteries secured by velcro.
The battery enclosure was a terrible print. I had to clean it up and glue on some repair peices so i wasn’t very happy with that so i will buy a 3d printer and do good one later on. This will do for now.
Cheers
