Re: "Copper/nickel sandwich" buses for series connections

My limited understanding was if the controller is asking 40A from a battery pack made of 18650-25R (2.5Ah, 20A-max) with no BMS (or a BMS that is 45A or 50A, meaning the BMS factor is irrelevant in this case study) then a pack made of 10S2P is 36V-nom (42V-max) 5Ah 40A-max you are pulling 20A from e...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Your motor must have been built on a Friday near closing time. Is the added pcb board new or have they been doing that for awhile? I literally can not remember if mine had a pcb board, but I think I would have remember if it did. I use an unsensored controller so I only use phase wires and just tuck...

OK, but even the RH spoke flange is not uniform not like traditional hub motor designs for the flanges. Whats the affect of saving that kind of weight on the rotational assembly without jeopardizing hub motor strength where its crucial at the spoke flange. I'm sure its been tested and is more then a...

Not to mention 27H vs 35H, better heat dissipation, not sure if the Grintech's motor is more efficient then Leafs. The Leafs 35H is better heat dissipation apple-to-apple, meaning if both using FF but its not really an apples to apples comparison for the different physical size, more metal, more sur...

Always best to measure the rim yourself. Chain Reaction has a size down to 182, 184, 186, 188, 192 on up if that meets your requirements. https://www.chainreactioncycles.com/spokes I've played around trying to find the right ERD of a rim to fit those sizes and playing around with the spoke calc to g...

Some specifications on rim websites can be wrong, I remember emailing Grin about a rim website I found for a rim with a differing ERD listing, but Grintech actually measures theirs so I trusted them and ordered spokes for Grintechs ERD #.

Re: Taking steep hills with a hub motor

Get a thermistor installed in the hub motor and have a controller that can read it and save your motor. I should have done that with my mxus 45H 3kw hub motor, and it would have been saved from melting. That hub motor was heavy a.f. and I never used it to its potential, I actually used it quite unde...
