    How about Hipower lifepo4 cells?

    Hi, I can report that hi-power are generally good. I have several scoots running on them, and no problem. They do take a while to come into balance with a BMS - but this is quite normal for LiFePO4. Perhaps the newer cells are rated 2.5 - 3 C; the ones I have are 2 C. However, that fits my...

    ThunderSky charger - no BMS?

    Hi all, I'm working on a charge profile for lithium iron phosphate batteries (LFP), suitable for large format cells (TS, HiPower, etc.). This might be extended to all LFP (A123, PSI, etc.) with different voltage setpoints. I've heard that the ThunderSky supplied charger...

    The Zivan NG1 revealed

    The Zivan NG1 is an excellent (albeit expensive) battery charger. 900 watts, three stage, and fully programmable. Unfortunately, the programming can only be changed with a factory supplied microcontroller. However, the end user can change the voltage and current setpoints. Best to...

    Generic A123/LiFePO4 charger/BMS

    There are many threads about charging and balancing lithium chemistries; everybody wants one. So this is a question to DoctorBass, and anybody else with the experience. Couldn't you use the MegaPower 960 for this? Here's a pointer for one with balancer...

    Myth Busters go Electric

    Hey all, Myth Busters are going to do a number of shows on electric vehicles. Apparently Jamie is a real fan of electric, and rides an ebike from his home in San Francisco to work. Don't have dates or times, but stay tuned. One show will pit an ICE car against a ThunderSky powered version at...

    I thought I'd heard it all . . .

    OK, we get some pretty vague questions, or completely unrealistic requests every day at Electric Motorsport. I usually let is pass (although I had thought of doing a series of the funnier ones) - but this guy really takes the cake. Names are removed to protect the guilty. So he wants an...
