I want to get another battery for my ebike but everything I’ve seen online ships from China and I’m worried about getting scammed/wrong product.
The company I bought my bike from is in America and they won’t ship batteries into Canada.
My battery is a silverfish style with a 4 pin connector port, a canon head charger port and it’s dimensions are 390mm X 75mm X 110 mm.
It’s 48v 15AH.
Any help would be appreciated.
While that might be true for some very gnarly air speeds approaching 10-20 knots, riding out-and-back would tend to cancel out most – but not all – of the windage effects. And such winds would almost certainly be noticed as a caveat to the ride data.
Certainly, I wouldn’t recommend drawing conclusions from a few or even a single data point. It’s an ebike, so going for multiple rides shouldn’t be laborious and in-fact should be quite fun.
I mostly just use my bike for commutes and charge in the middle. So, the one-way matters. But sometimes, I can drain like 80% of the battery going one-way and other times its like 20%. Of course this will depend on how much assist you use. With a good tailwind, I’m pedaling hard enough the assist might do very little outside of accelerating after stopping. With a bad headwind, the assist might be at/near 750W nearly constantly (and still sometimes dipping down below 20mph) and my contribution is pretty negligible. I do live in a relatively flat area nearish to the coast… so winds speeds might be a bit more variable here.
