Re: XPD programming

Thanks so much for the advice, By the looks I have it sorted now, It reads settings uploaded successfully :) now to build a battery so I can actually get this thing up and running again! For anyone's future reference, you need to either be in root or a dialup group, whatever that means. So basically...

Re: Lipo failure

Hey so did some further investigation of the failed pack, in an attempt to look for a short/fault. However, this thing burned nice and hot, burnt through most of the balance leads entirely, and the thing is more of a burned out lump than something recognizable. It's very hard to tell what could have...

Re: Lipo failure

Here are a few more pictures, showing the charging system i used and where it normally gets charged. The whole setup is off grid, being run from 500w of solar panels and a 300ah 12v battery bank. I don't think this had anything to do with the failure, as its really just a 12v source to run the charg...

Re: Lipo fire

Thanks for all the helpful posts, I realize that my level of care with charging was not perfect, this was more of a post to remind people that complacency happens, and a bit of carelessness can result in a potential major disaster. This is why i charge the bike outside, where it's not going to cause...

Re: Lipo fire

I think it might be wise for me to invest in a better charger then, i'm pretty sure my current charger is not the best quality around. Any recommendations on a good brand of charger/ something to accurately graph the discharge of each cell?

Re: Lipo fire

I'm pretty sure i checked them when fully charged, which might have been part of this packs downfall, and there's every possibility that one of my cells had gone bad and i just didn't pick it up. I will definitely consider a safer battery technology for the next build. However all the alternative ba...

Re: Lipo fire

Yep, now to start the long process of looking and building a new battery pack, hopefully this time it won't catch fire! I balance charged the batteries every time, although some of the connectors were a little bit dicey, so there is a possibility that it didn't balance properly. I did check every ce...

Lipo failure

Hi, just wanted to point out once again that you can never be to careful when using lipos. I just had a 24s 5ah lipo pack burst into flames while charging. To charge i split the pack down to 6s4p and balance charge using a rc charger. I was in the shed while it was charging outside, when i heard the...
