Re: Crash Thread - lucky

Sidwalks are the most dangerous place to ride. That's why they're called side walks not siderides. Not around here. Here, sidewalks are, most of the time, the safest places to ride. One just needs to go slow. Going slow is better then being hit by a car. Around here if you ride in the street during...

Re: Nucular Electronics owner's thread (setup infos, FW updates, links etc.)

The dc source has to be lower voltage than the battery on the bike for it to work. I knew that, and I believe it's best to have it not too much below the packs I want to charge for best efficiency. The lowest voltage on my bikes is 60V nominal, so the most likely voltage for the home based pack wou...

Re: Anyone using solar panels to charge thru Nuc controller?

...stick my bike on the back of my truck... I feel sorry for your bike, embarrassing it like that. No bike of mine has ridden on or in a gasser since LFP came down for a visit 9 years ago, when none of mine had enough range to reach the beach. It's time to step up and build some electric transporta...

Re: Anyone using solar panels to charge thru Nuc controller?

Has anyone using solar panels as the power supply for charging via the Nucular controllers' Converter function? Would there be any special considerations or would the controller operating as a converter effectively function as a charge controller enabling the use of panels direct with only a diode ...

Re: Suzuki GSX-R e899 K2

That torque constant equals a Kv of 7rpm/volt, so you'll need to run a pretty high voltage to get to the rpm you want, though with that amount of torque how much gear reduction do you really need? The low winding resistance supports the level of current you'll need to achieve that torque, especially...

Re: Suzuki GSX-R e899 K2

If it's a BLDC motor you need the Kv and the expected phase-to-phase resistance. Then you can get an idea of the current handling and torque potential of the motor. Kv tells you exactly the torque per amp the motor will make, which I'd trust long before I would the manufacturers hype. Regarding your...

Re: Chinese Pit Bike Conversion | Nucular 12F | LMX-Motor 60mm | 18s 16Ah LiPo

Looks like a nice little donor for an e-conversion. If the swingarm is steel, I'd definitely weld the motor mount to the swingarm in front and below the pivot point. The purpose would be to eliminate chain issues and make it as quiet as possible, as well as obtaining the anti-squat attributes of mot...

you could use one switch if you add diode. from controller EN -|>|- to switch (dc-dc gnd) otherwise you will apply high voltage on EN input and controller will be probably dead. really dead. very very. not fun to fix. i warned you. im working on 3A dc-dc for controllers Yes actually adding a jumper...

My new Nucular controllers will be my first chance to employ variable regen, and I'm wondering what have you guys found is the best method of input?

Re: Any need to Balance?

In the future, prior to pack assembly put all cells in parallel for a day or 2 to get the cells in perfect balance to start. I always used to do that for traction LFP banks. Parallel and charge to 3.6V, then assemble bank. With LFP, you must charge. 3.3V at rest is anywhere between 45 to 80% SOC. T...

Re: Some help with ebikes

Absolutely do not put your controller inside that wooden box. They need a cooling air flow, because a % of the energy going through a controller is lost to heat, at times as much as 5-10%. That's why their shells are aluminum will cooling fins all over. Insulating it inside a wooden box would quickl...
