Re: Is it ok to charge a hot battery after a long ride at 5 amps?

Any batteries, any size, any chemistries...
None like being charged or discharged when hot.
Some you are just killing them slowly, some will leak gas and start a fire.

The best indicator of battery health is heat, although most EVs are only equipped to monitor voltage and Amps.

Re: Rear hub or Mid-drive (should I just flip a coin?)

Slow climbing requires a mid drive. Fast climbing is hub domain. Hubs that you will climb with, require better batteries and bigger controller. Mid drives are retaining the bicycle feel, while hubs are more moped like, even motorcycle like when high powered. Hubs, big ones especially, can survive am...

I'm close behind. I roast them myself, maybe a week's worth at a time.

Re: Ok, I bent the new rim... Looking for a stronger rim.

The best prevention for pinch flats and rim damage is riding tubeless with Cush Core inserts and half a cup of slime. That is because the insert won’t let the rim pinch the tire or touch the ground. It won’t let the tire off the rim, even riding on a flat. The slime will plug most of the flats, and ...

Re: Chinese pack + new cells

You got it right. Charge them together, at a rate that suits your cheap battery. Discharge rate too, should not exceed the C rate of your cheap battery. You see where I am going? Best is to build one battery, using only high C rate cells of the same capacity. I would ditch the cheap Chinese battery,...

Re: Question about battery for Ebike

You need lots of power to benefit full advantage of a big hub motor. If I was building with that motor, the battery would be suitable to feed 500A. This means that using low C rate cheap cells, you will have to carry them in a trailer after your bike is filled with all it can hold. Stop buying cheap...

Re: Chinese pack + new cells

This answer was about your original post. Adding your new, better cells to your Chinese pack is meaningless. Better building another pack with new cells and use the 2 packs on parallel. Then, when your Chinese cells start to fail, you will still have the good cells together and working.

Re: Hub motor industry dying?

We have made, and some manufacturers are making, hub motors with liquid cooling. Yet, no hubs had been made with advantageous power to weight ratio to take real advantage of active cooling. The one that was tried here was a Clyte HS, that is a pretty light motor with poor life expectation in mountai...

Re: Chinese pack + new cells

Yes of course you can. The cells are close enough, same chemistry, same C rate.

The only downside is the 2600 mah cells will only be used at 2500 mah to match... the weakest link.

Re: Chinese pack + new cells

This will not improve your discharge rate, only the max power availability ( by 1/7 if you add 1 p)

The limit of a chain is its weakest link.

But, if you feel that a front build is suitable for you, there are no good reasons to use a rear motor on the front.

Of course, rear motor. Front motors are not good for a suspension fork. You can build it safe, but the fork won’t work good anymore. Some fork can be custom tuned to work with the weight of a small motor, but the performance of those motors doesn’t justify the expanse. So, front build are ideally ri...
