voltage stays so similar the whole discharge it’s nice. As apposed to ion cells which you really notice ur power and speed dropping the further u go.

That has one pro and one con. Better ride, but I have to pay more attention to my remaining battery. But with a kWh pack that wouldn’t matter as much as with a lil boosted xr pack.

I strongly prefer LiFePO4 but they are huge and heavy.
If you’ve got the space for them, they are fantastic.
Better than the other li-ion types in every other metric besides size and weight.

With his dimensions looks like you could get roughly 13s 6p 18650 in there if you don’t account for the bms. Using 30q that only puts you at around 0.8kWh nominal. I would charge around $1000 with how expensive 30qs are now a days. They are more expensive than the 40t for some reason
