after a couple years messing with these...... the concentrated straigh truth is....
We were talkng about that a while back, and complaining about the stupid connectors as an install. Good to see these showing up in a way most people can mount them without bitching up thier wiring harness. Nothing says "quality" like some half-assed soldered together potential wiring fault.after a couple years messing with these...... the concentrated straigh truth is....
1 you have to have a modern bike to run it. Older non-electric controlled bikes like old cb750s and stuff dont have the charging amps to recharge them
2 yes they are super light
3 yes they are super powerful
4 yes they are super small
lipo is dangerous. Dont use them. get life04. pretty close to the same thing but a lot safer
And finally..... This thread has almost been made extinct becase there are a ton of companies out there now making these packs for a great price with a warrante and everything. Shit I even seen one in a mag I picked up yesterday that was the same size and shape as a stock battery but only weighs a couple pounds for stock applications.
It's the only way cells can be linked without damaging the cells. I'm not sure who you heard that info from because commercially it's the only method used.How did it went with spot welding. I heard they tent to explode sometimes. Does the settings differ from NiCd NiMh ones?
They are dewalt 26650 cells, I stock piled "broken" 36v packs for a year or so. But you can buy new production a123 LiFePo4 cells online (not ebay) for about $8 per cell.Where did you get the cells? Last I looked on eBay I couldn't find them.
Interesting! All my packs have at least 4 layer of nickel strips. Reason being, the first pack I made with nickel plated steel strips(crap) lit up like the 4th of July when I tried to start my bike.We have a spot welder at work, and we make NiCd, NiMh packs. And the guy, responsible for makin em now, claims that if you overlap nickel strips one over another they tend to explode. That i dont believe 100%. Thats why i asked about settings
I guess one other thing to note is when welding the tabs, you want to keep the heat to a minimum. I went from cell to cell only doing one weld per cell until each cell had 3-4 welds. The welder should be adjusted so that a solid weld is produced but no more current than necessary to keep heat down.We have 18650, and couple of clients wanting to do it
