Replacement or spare 10AHr Lithium Polymer Nano™ battery.

Compatible with nano Brompton.

10AHr Lithium Polymer battery. Estimated range - up to 60 miles on a single charge. Supplied in an aluminium and plastic moulded e-bike case, which fits neatly in the bottom of all the brompton front luggage. The battery life is between 600-1000 cycles, which should be enough to last 3-4 years of normal use before a significant reduction in capacity is noticed.

Actual range achieved will depend on a number of factors, including how much assistance is used, how hilly the terrain, and how much weight is being moved. Expected range should be between 15 miles and 60 miles.
