5000mah Neu Lipo Size?

[nativepaul]

Is your 3s pack 20, 25 or 30C?

also does anyone know how big 8 gauge wire is? I was expecting huge wire but it is not much bigger than I normally use, they are 5mm diameter around the silicone and about 3.2mm diameter of copper, if that's not 8guage can anyone say what gauge it is?

This should answer you wire gauge question.

Thanks for that link Jhautz, it is indeed 8gauge, its just smaller than I was expecting it to be, I must have been using 10gauge for years, thinking it was 14 gauge.

I just went to charge the Neu pack before I use it but it wouldn't wake up my LBA10 balancer, after some poking around with the voltmeter I discovered that while the balance PLUG is hyperion compatible (after a little shaving), its balance lead has a common negative and individual positives, unlike my other packs that have a common positive and individual negatives.

It looks like I will have to strip the heat shrink off the pack and resolder the balance wires onto the opposite tab of the cells before I can use it, I sure hope they have copper tabs so I can solder to them.

I'll give it a day or two first tho, in case anyone else can think of a way around it without risking puncturing a cell removing the shrink or cooking a cell soldering, its not something I want to do, but I cant think how else to make em work. I already soldered connectors on and shaved the balance plug before I realised so I can't send em back.

On the hyperion plug you can lift up a little plastic holder and slide the wire out. I don't know if this solves anything for you but, maybe you could just swap the wires around.

unfortunately there is only 1 negative wire so I could only swap 1 of the 4 cells around that way.

after thinking on it a while I'm pretty sure I'm gonna have to open it up and swap the leads round on the tabs.

Thanks Cartwheels, I took apart an old LiPo to practice on today and found that its not a common positive or negative at all, its just taps from the positive or negative terminals, so I rewired the plug like you suggested and it seems OK, the balancer came on, but only 1 cell flashed at me, hopefully that's just because only 1 cell was out
