Re: rode over my lipo battery at wot

so new news. The week before last I was down at my girlfriends farm in Dorset. This seemed a perfect opportunity to meet another UK ES member Burtie. We arranged a ride to a local pub and then went back to his for a BBQ. Pippa and I enjoyed every minute and Burtie was an excellent host. He has also ...

Re: paralleling hobbyking E4 chargers to get 9 amps charge?

I have plenty of 12v power supplies as im selling them here in the UK. I dont know yet whether they are isolated, Im not sure whether just giving it a go is sensible?

The other option i have is charge the 3 3s packs singly but that is a bit of a faff although i have ordered 3 chargers.

Re: this needs an e Conversion and im in

that is amazing, so basically he has upgraded away from feathers and beeswax, to carbon fibre and jet packs. Let hope he doesn't become a victim of yves strike.

I think the best way to get high with the electric motors is paragliding.

Re: paralleling hobbyking E4 chargers to get 9 amps charge?

So anyway No one replied and i got impatient. Last night i ordered 3 of the E4 chargers and one battery medic. I figure that between a cellog 8s ton monitor, a battery medic on balance mode and the 3 E4 chargers I will have the 3p3s booster pack charging just less than the 12s3p main pack. total cos...

Sorry Gordo I have to disagree, I've read these whole thread through multiple times if anything pavliks first post was the most helpful after that it was all stuff that doesn't help my goals. The reason I used a pot was to experiment and thank for the hint about 0 resistance I did not realise it. I ...

Re: 72v + users, do you use a pre-charge resistor?

yes I do, i just made a connector with 3 large seriesed resistors from an old power supply, does the job fine. only running 18s at the moment but should work in theory for higher voltages.

If you are going to quote then use quotes if you are going to copy from another contributor then don't do it on the same page of the thread, if you were just pointing out the futility then please don't. Got to be optimistic else I'll never learn how to repair these things

Re: broke my golden motor controller any one fix these?

Checked. Both ways. Beeps both times no other fets showing shorts though, if I replace the fet and not the resistors for gating will the fet just blow again, I thinking yes but I'm not sure.
