Ah conversion

[billyboya]

if my battery says 5.222 Ah how far in miles can that be is there a way to convert

you multiply the Amp Hours by the voltage to get the standardised WH. Each mile uses on average about 10WH. The last 20% of the capacity is unpleasant to use because the voltage is close to the protection cutout, you should not count on it.

For example, if your battery is a 36V battery, 36V * 5.2AH = 187WH.
80% of that is useable, the last 20% can be used but unpleasant.

You can do about 15-16 good miles with it, with 3 more on low assist.
Another unpleasant side effect of such a low capacity battery is how much power you can pull on the battery when climbing a steep hill.
The maximum current draw is usually given as 1.5C to 2C. C= capacity/H, 5.2A *1.5=8A in your case. It's not much available to climb a steep hill with. A minimum 8AH is recommended for an e-bike.

Each mile uses on average about 10WH.

with huge variations depending on the hilliness of the terrain etc. The Bosh range assistant won't cover batteries that low capacity, but you can get an idea of how much the details change the range from https://www.bosch-ebike.com/en/service/range-assistant/

ok guys thanks for your help
