Help! Battery conversion

[AndyHunt]

Hi, my no. 1 bike is an Order f40 Gain , but I have a cheap Chinese ebike for shopping etc.
It uses a "frog" Type battery and was not taking a charge, so I bought another battery without taking enough care and got a 24v instead of a 36v.
Is it possible to have it up-rated to 36v, and any recommendations of anywhere in the UK that would do it?

Sell it and buy again correctly.

For your old frog battery simply get it re-celled at ebikebatteries .co.uk.
