    We've been getting a flood of questions and interest in the BMI battery packs lately. It's difficult to cover everything in individual emails, so I'm starting this thread as a repository of the tips tricks and answers to the many questions we see over and over again. To get things started...

    Motor upgrade suggestions (more speed needed)

    I'm looking to upgrade to a faster motor. My setup is currently a 26" mountain bike with a WE-BL motor. It's running the stock motor controller but it's been modified to put out about 38amps (instead of the original 20). I've got 16 BMI LiFePo4 cells in series giving me a little more than 50V...

    Inverter for motor controller

    Does anyone know of a motor controller that steps the voltage up like an inverter does to give you more speed from a lower voltage pack? I'd like to find a controller that can work with a 48V pack but boost the voltage up to around 70V to allow more speed from the same battery pack. I know...

    PING Pack BMS cuts out early when > 100F

    I'm at just over 1000 miles on my 10AH 48V ping pack. Everything is just great with it except that I keep tripping the low voltage BMS cutoff after only 7ah whenever the temperature outside is over about 100F. In the mornings when the temp is below 80 or so, I easily can put 9AH+ on the pack...

    BL-36 at 48Volts Review

    A few weeks ago I bought a BL-36 from Wilderness Energy. This is my first e-bike. The new version of the BL-36 is rated at 650Watts, and has a start from 0 controller. Since it was rated at the same power as the brushed model and is supposed to get more range than the brushed motor, I decided...
