    It is time to disband my DIY EV project, the vehicle will never show up and now prices for another similar car are out of my reach. I have 15 Leaf battery modules (8kWhr) "Lizard Cells" from a 2017 replacement pack (2012 car w/24kwhr battery) for $110/ea, or $1200 for all modules. There are...

    Hi all! I'm an engineer by day doing mostly PCB design, and at night I tinker with random electronics and EVs. In college I did FSAE, as a kid I did electric RC planes. Now I have a ~35HP electric kart (16s Leaf cells + ME0709 + 500A motor controller, very fun and a bit terrifying) and also one...

    I'm currently interested in converting a small speedboat to electric, using this 40kw peak brushless electric motor. The plan is to run it on around 100v, using the 50kv variant of the motor to produce our 5000-6000 RPM desired. This motor is 40KW peak, and around 25KW constant so the battery...

    Should I buy a 4S PCB? And would it have to be rated for 66A continuous discharge, if the most I'm ever using is 30A ?
  6. Batteries and Charging
    I've tried searching for two days and I can't find this question on the forum. I know some folks have asked about Pb + super capacitors, but what about a little more of a compromise? How about an energy pack based on Leaf modules, say 44 for 330v pack ~20KWh, and a booster pack of 100c LiPo...
  7. Batteries and Charging
    I am going to put some Nissan Leaf batteries in my converted lawn tractor in place of the 3 mobility scooter batteries I have now. Am also going to replace the three big 70ah 12 volt batteries in a Recharge lawn tractor as well. So I am trying to figure out exactly what kind of batteries they...
