Re: Critique my plans for my first build!

Oh, and it's generally considered bad practice to use BMS settings to limit charge voltage, though it can be done. The proper way is to vary the voltage that the charger puts out. Some cheap ones (like mine) have a potentiometer that can be slightly adjusted, and better chargers have a programmable ...

Re: Critique my plans for my first build!

Well thought out! The motor kit you linked is very similar to the two kits I've bought. They do all have the 6-bolt adapter for disc brake rotors, and generally work just fine. I also have the Malectrics spot welder, and it has worked great through the four batteries I've built so far. I was advised...

Re: MTB for EBIKE Conversion

I apologize that I can't help your search, but was curious if you were using regen braking. I use a 1500w direct drive motor (no regen yet) in an aluminum frame with one torque arm, and it hasn't affected the dropouts a bit. I do think it's lame that most torque arms still allow some slight rotation...

Re: Looking to build a bike

I agree with the 72v battery if you want 40+mph. Your link was for the 5 turn Leaf motor (Grin's default), and here is a link with the 4 turn (Leaf's default config) rpm/v numbers pasted in: https://www.ebikes.ca/tools/simulator.html?motor=Leaf%205T&batt=cust_52_0.2_20&cont=cust_60_120_0.03_V&hp=0&a...

Re: Bonanza "Bulldozer" Dual PhaseRunner AWD

Ah, yes. Neptronix was saying the same thing for his BikeE and Cannondale. The Lynx however acts more like a tiller when it's tilted back, so the narrow bar is just fine, and more comfortable than I thought it would be. (I was originally hoping for under seat steering). It does only require the smal...

Re: Portable 5-8 amp charger

I do bring my Vruzend 52v charger with me to work in my cargo pocket when I ride. It's very light, but only provides 3 amps.

Would you rather have more of an onboard charger like this? Unfortunately this specific one doesn't offer 52v.

That Lynx is really cute, full suspension packed into a tiny package. But those handlebars are so short.

Re: low batter voltage cutoff.

Get a voltmeter so you can watch battery voltage in realtime as you bike, if you can. This will help to understand what's going on.

Looks like the positive end insulators took a beeting between the last two cell groups. I'd bet the cells are fine, but the insulation should be replaced and beefed up on the positive ends.

I would first charge that sub pack to 4.2v (or same as the other cells), then check capacity on the whole pack, carefully watching each sub pack voltage and discontinuing discharging when the first sub pack reaches 20% DOD, then discharge each remaining sub pack to compare balance of all cells.

It just goes to show that I need to redo my recumbent testing. It was too windy yesterday, and it's very hard to guess an average watching the watt meter bounce around while trying to hold the throttle and speed steady.
