nano battery options

Batteries are so key to choosing an electric system.

At nano we offer a wide choice of batteries including a number which can be taken on passenger planes.

If you are buying a whole nano system the battery, charger and adapter are included in the kit price. Additional batteries are available at the prices listed below.

Bosch and Oregon 4Ah (144Wh) 36V batteries

These batteries can be used with the nano system with the addition of a nano adapter and are included in the kit price - just let us know which you prefer. The only real difference is that one goes inside a Brompton bag and the other can go into the pocket of the larger bags.

These are all standard appliance batteries designed for heavy duty use in drills or garden equipment.

We have been selling them for use in the nano system for a number of years and they have proved very robust and reliable.

They both weigh just over 1kg in weight and have a range of 8 – 16 miles depending on the terrain, riders weight, weather etc. Without putting in much effort at all on fairly flat ground you should be able to get around 8 miles on a single charge.

The Bosch battery goes inside a Brompton bag and is used with the nano in-bag connector. Red or green batteries work in exactly the same way with the nano system.

The Oregon battery is fitted into the pocket of a T, C or S bag (newer versions) or the older style T and C bags but not the old S bags.

Either battery can be fitted into the Compact 6 bag

You can buy the battery and charger from a number of power tools companies or from nano.

13Ah (481Wh), 36V, Hailong batteries

These batteries are supplied with a nano adapter already fitted.

The battery weighs just under 4Kg and gives a range of 25 – 50 miles depending on the terrain, riders weight, weather etc.

Bags - The battery fits into most of the standard Brompton luggage except the mini O, tote and Compact 6 but is not recommended for the roll top or shoulder bags due to the weight of the battery.

How to choose - Most customers choose the 4Ah batteries as they are lighter and more flexible to use. The larger batteries are only really needed if you live in a very hilly area or are regularly needing to use the motor for long rides of 30 miles plus.

Flying with batteries - Up to 2 of the 4Ah batteries can be taken on a passenger plane, subject to approval, however the larger 13Ah batteries are not permitted due to IATA regulations.

Expected ranges listed below depend on a number of factors, including how much assistance is used, how hilly the terrain, and how much weight is being moved.

Charging takes proportionally less time if you have used less of the battery capacity before charging.

Life expectancy - All batteries have a life expectancy of around 800 charge cycles but are expected to reduce capacity by up to 15% each year.
