Wasn't sure of the best place to post but here goes.
I have a pdq power trike (http://www.davincimobility.co.uk/index.php?page=pdq_powertrike).
Currently Im using the lead acid 36v 7ah battery. But it dead.
I want to get the 36V 13ah Lithium-Ion Battery, but it £450 !
Im thinking can I just use something else ? Like this 36V 10ah Lithium-Ion battery from ebay, as its £235 ???
I could convert the plug to fit as its a kettle plug that goes into the trike. But Im not sure on the 13ah and 10ah ??
Anyone know about batteries ?
