    My DIY 48V 16Ah battery cuts out at 47 Volts

    As the title says, I built a battery pack 13s5p using LG MH1 cells salvaged from scooter batteries. I tested each cell on a Opus battery charger (on the 1A discharge setting) and they were all showing around the 3200mAh they are rated at, so it should be a 48V 16Ah battery. I built it to run a...

    13s5p Cell Arrangement for Reention Polly DP-6C

    I am building a battery for the Reention Polly DP-6C battery case for 65 18650 cells that came with nickel plates. I didnt get any documentation on how to place the cells. Based on the nickel plates I have attempted to infer how the cells should be arranged in the holders. I got an image off...

I just received everything and on inspeciting the 13s BMS they provided with it I notice that a number of components are not populated on the board I received, but the picture of what I was supposed to receive shows the...

    Upgrading 1500w kit Controller - recommendations?

    Hi, I am looking to upgrade the controller that came with my cheap CSC 1500w rear hub kit. The motor is the same as the one that comes with the Violamart kits, I think. It has a 12x5 winding and came rated at 1500w. How much can I expect to push this motor say if it put in statoraide to...

    Kona Blast Worth Upgrading Forks?

    I got this Kona Blast for $50 and have moved my 1500w rear hub over to it because my previous frame had rim brakes (an old chromo steel Marin), and figured the disc brakes would be a good upgrade. It is working okay, however when I brake hard on the front the wheel tweaks to the left quite a...

    Used Jump Bafang Hub for Budget Build?

    Just recently built up my first e-bike with a 1500w rear hub & 52v20ah battery and am having tons of fun. I'm looking at making a second e-bike for my gf to use when she visits. She is quite small and won't want to go very fast (20-30 kmph max probably) so I am looking at putting together a...

    CSC 1500w Rear Hub build

    Been interested in building a diy e-bike for several years and finally pulled the trigger on an ebay special, branded as CSC conversion kit, 26" rear wheel 1500watts. I picked up a UPP Triangle battery 52V-20ah with 50A BMS to go along with it and a couple torque arms off amazon. I tuned up...
