Replacement batteries

[brindledog]

Trying to return to e-biking after a period of ill-health we find ourselves lumbered with two dead batteries - one won't charge and the other will charge but only functions downhill for a mile ... so, need 36v 8ah two prong battery. I've noticed an add on Ebay for GreenCell batteries, £150 each. Can anyone please advise about this company (or any other?). It must be at least 8 years since I last bought a bike battery!
Many thanks, and best wishes for sunny cycling.

Can't recommend them personally but they seem/appear like a big outfit,a couple of forumites have used them.

This last post in this thread though not a great advertisement for the company supplying the right item does show them in agood light regarding rectifying issues.

Two new batteries, now both dead :(

Connector is called EC5/Euro connector. Unless your controller is dual voltage or has 63v main inlet capacitor then it will blow. Your motor will run 33% faster and may heat up more esp on inclines , the rpm will increase by 33% as well. Generally a 36 v hub run at 48v will be less efficient...

As long as it fits and the voltage is right it need not be 8ah. A battery with bigger ah should work well and give better range (and be more expensive).

£150 for 8aH is a bit pricey. Can you show us your old batteries?
