Well it’s done. Just need to make me a bracket for the BMS to hang above the battery. Or I’ll just strap it to the battery maybe.
I only took a few pics during the final stages as I was trying to get it done and forgot to document the last few steps. Pretty much folded the pack in half after I put on my nickel plates with soldered on 6ga wire. Used a torch and some solder...that worked well. It’s not moving. Lol. The. I spit welded those strips with cable on them to the battery ends. So it has the full length of the battery parallel group and cable runs the length of it as well. Wrapped it up in a mile of kapton tape and the neoprene padding. Almost looks like a professional pack. [emoji12]
Maybe in the future I will shrink wrap it. But for now it’s a very snug fit. Just gonna leave it alone as it works to be tight inside the frame.
Took it for a little ride at 75.5 volts it dips down to 60 when full throttle is applied for a bit. So sag is there but performance is bang on. It scoots like crazy and feels great. Nice to have the capacity.
For sure the next project in the bike is a better charging setup. My 3A Charger takes forever to charge it up. I need something like a 15A charge so it does not take forever. Going to try to build a series Mean Well power supply setup from a pair of (LRS-350-48) 48v power supplies. Each puts out a max of 7.3A so hope to get 14A total and 84V once adjusted down on each power supply.
