Hi - I have a volt pulse with the standard 36v 12 ah battery and in very hilly conditions I'm managing to get about 38 - 40 miles from it. I would like to go further and I'm wondering whether to upgrade to the 36v 16 ah battery ( which costs £490) or whether to carry a spare - i.e buy another 12ah ( which costs £290) , or even the cheaper 10ah battery at £240. Any advice would be much appreciated.

The 10ah one is the best value for money. I'd buy that, and take two when I needed giving flexibility.

Thanks for the reply. I suppose I need to find out what they all weigh and how much distance I'd get from the 10 ah as compared to the 12ah.

Don't overthink it.

A 10ah battery will give you proportionally fewer miles compared to the 12ah.

You say you get just under 40 miles from the 12ah one in hilly conditions.

That's about what I'd expect from a legal ebike - they are all much the same when it comes to power consumption.

The 10ah battery will give 30-35 miles.

After googling I discovered that "overall efficiency is measured by dividing the watt/hours used by the battery charger by the mileage achieved, giving a figure of watt/hours per mile." On this basis it's definitely better value to get the 10ah battery as a spare and using that with my 12 ah battery. Thanks again.
