    Wiring and BMS setup for 13S2P pack with 26650 cells

    I either fabricate them or research & find them. Most things you think of have already been thought of. A few years back when I was building these I'd built a 3D printer and was making much more of my own plastic/metal parts. But I don't have one currently so I'm having to source elsewhere...

    Wiring and BMS setup for 13S2P pack with 26650 cells

    Here's a https://www.instagram.com/p/BSRe6bzBbLd/ of my current pack build/wiring. I'm out of silver solder & flux right now, so waiting for more to arrive to finish it all up, add balancing systems & power/charger XT90 plug. It's only wired 13S1P X 2 right now, all reading correct voltages in...

    Wiring and BMS setup for 13S2P pack with 26650 cells

    Paralleled batteries are batteries that will add Ah instead of volts as series batteries do. For instance: If you wire in series 3.7 + to 3.7 - to 3.7 + 8Ah cells, you get 11.1V 8Ah. If you wire cells parallel 3.7 + to 3.7 + to 3.7 + to - to - to - 8Ah cells, you get 3.7V 24Ah. My setup is...

    Wiring and BMS setup for 13S2P pack with 26650 cells

    Like the title says, I'm Building a 13S2P battery pack. I'm trying to figure out how to wire it most safely and efficiently. It's been a long time since I've build a custom pack of this size & as I'm using $220 worth of 60A 3.7V 26650's, I'd like it to not explode, short, or go bad anytime...

    How Many Turns for a 48V 40-60A eBike Motor Using 10AWG Wire?

    It's been like 3 or 4 years since I've built an electric motor & I've forgotten mostly everything and need some help getting this worked out for those that don't mind. I'm trying to build a 48V 40-60A eBike motor. I'm using 200C 10AWG Magnet Wire. I have a 24 pole stator core. The stator core...
