If you want capacitors to last you want them to be rated higher than the voltage they're actually going to see. A 52V nominal battery charges up to 58V. You're going to have a very short lived controller.

The saddle is a weird angle because nobody sits on it, they stand and sometimes use it to grab onto.

Nah, and not even worth inventing.

man, this is a really bad idea

What kind of person writes the word diode in doctor evil quotes? it makes you sound skeptical that they're real, which is a bizarre attitude because it's one of the oldest and most rudimentary electric components ever invented.

It's magical technology is that whenever the two battery voltages don't match, the bike takes power only from the higher voltage one. When the voltages match, it draws equally. And then it also prevents reverse current from entering the lower volt battery. My friend, that is literally the...

that "battery blender" looks like a diode in a $150 plastic box.

know the following: - how fast you need to go - what rpm your wheel needs to turn for that speed - how much power you need to go that speed get a motor that makes the required power, and learn what rpm the motor spins when it's doing so find a gear ratio that matches that motor rpm to wheel rpm.

The part where I was taking to you comes after I quoted you. What I said before it was for the OP.

This is histrionic. I could make walking to get a coke from the fridge sound like a 50 step process if I want. But if it's a lot of stuff like "raise left leg slightly", "lower left leg to place foot on floor 10cm in front of previous location", "raise right leg slightly", everyone would know...

Seems like more effort to replace all your brakes than it is to epoxy a reed switch on the lever.

A fully charged 52V battery reads 58V+ on a voltmeter.

That's very obscure, I've never seen one. My supplier goes from 50v to 63v with nothing in between. I say if whoever is selling this controller is trustworthy the components they use will be genuine. As always, suck it and see.

48V ebike stuff should always work on 52V batteries. This is because 48V is a "nominal" (bullshit) figure. Fully charged they're closer to 55V, and near flat are... much less. everything gets built with parts that can handle more than that as a kind of safety margin, which is also enforced by...

I don't know, I've slept since then.
