That way your LCD will be always on. I’d wire it in after the loop key. Its personal preference but it would bother me if it is always on.

I’d prefer the Hoku Flex
& 3. Use one of the many gearing calculator tools and choose depending on your preference.
The charger works. Personally I’d go for a D/C plug. When using those 3 pins just get a diagram and find out which is ground/positive and wire it in. When using a BMS you will have to look for its specific wiring diagram too, to know where to wire the charging port in.
You can also use an xt connector to charge the batteries. Many people here use quality 18650 cells without a BMS and use a regulating charger to charge them up to 41v only. It preserves the cells.
Changing the LCD won’t do anything in terms of it being on. What @TranxFu is saying is that the LCD will always be on in your current configuration. I recommend putting it after the loop key as well so that way it only comes on when your board is on.
Don’t go lower than 14 teeth on the motor, otherwise the belt will skip sometimes. If you want more torque and lower speed, just increase the teeth on the wheel pulley
I use Lipos myself but I have heard that 25r cells are bad about voltage sag.
30Q cells are suppose to be better even though there discharge spec seems lower.
another thing to mention is a 10s2p with either 25r or 30Q cells is really low.
10s3p is minimum to go, better is a 4p configuration.
Otherwise your cells will have a hard time and wear out soon.
I’m not sure but I think from what I’ve heard that they’re better than 25r’s
Seems like 30Q are best from what I’ve heard
Also Like @TarzanHBK said, you can’t do a 10s2p with 18650. You will need at least 4p
Yeah as mentioned before I wouldnt go below 10s3p, Preferly 10s4p. Or if its a space issue it might be worth going with less serial connections for more parallels to increase the discharge rate. Just a thought!
Not much experience with anything else than my own 10s4p tho…
I’m not sure about HE2 cells and I know nothing about VTC5 cells.
If pack size is a concern I would take a look at A123 Lifepo4 cells.
They are supposedly the real deal with 70a discharge per cell
Full charge voltage is 3.6v so a 12s2p would give you 5ah with 43.2v full charge and 140a continuous current.
They have much higher cycle life than Li-ions as well.
The only other option I know of to have high power in a compact system is with Lipo packs.
