My kids (3 boys)and I have been playing around with electric scooters for a few years. We tinker, upgrade, and make them go much faster than intended. Our current focus is on a few Razor E300 scooters that we have installed24 volt450 wattbrushed motors that we over volt at 36 volts. With stock gearing top speed it about 32-33 mph and with a larger sprocket on the rear wheel it slows down to about 25 mph top speed, however it will climb any hill with ease and will stand on the back wheel at full throttle. Very fun with that type of acceleration. In any case, the point behind this series of posts, we have outgrown the SLA batteries, and we have been using some 5s LiPo packs, but I really wanted to build out some Lithium18650 packs.
I am looking to put together two 5S8P packs so that I can reach 36 volts but still charge them individually on my imaxb6 charger.Still not 100% sure I can fit that many cells without getting really creative, but worst case I will make them 7P.
I am still in the process of testing cells. I have tested over 100 cells and as of this writing I have 57 cells over 2000 mAH. Most of them are Sanyo cells out of Lenovo 6 cell packs. I still have about 28 packs (~170cells) that I need to test. I am hoping that when I am finished I will have 160 cells over my threshold of 2000 mAH that way I can make 4 total 18 volt 16 AH packs. On a side note, thinking hard about taking the cells that are between 1600 and 2000 mAH and making a large but mobile(3s) pack to power 12v items during camping trips. Might even pair that with one of those small solar panels to keep it charged up.
Here are some pictures of my 6 cell charging holder, batteries that I have tested and packs that are still waiting to be opened and some of the scooters we have upgraded.
I'll update as things progress.. Thanks for reading about my project.
