I'm based in Leeds. I'd be very grateful if there is anyone nearby who can help.

Ah that's a bummer. Is it possible it could be a minor issue that can be fixed? Eg replacement sensor part. For future ref, which motors are more repairable?

I've recently bought a gazelle e bike with a steps e6000 motor with a potential fault with the motor. I bought the bike without the battery as the seller would rather keep it for another bike. Does anyone know if it's possible to troubleshoot the motor issues without a working battery. I'd like to try to get this bike working again but don't want to commit to spending £300 on a new battery to find out the bike is beyond economic repair.

This seems to be normal in the UK. Can you name any UK sellers that do specify the specific cell used? I think eclipse do (who are sourced by em3ev) but they are out of stock.

LG 18650 3500mAh The BMS max current is 25A Edited: I sort of presumed unless I bought from a reputable UK based seller that you are on your own with repairs/warranty.

Ah ok, understood

I'd like to purchase from you but my budget is quite tight so I'm not sure I can afford to. Additionally I was hoping to buy a bbs01b with the gear sensor option and I read that your selling with model without that? I'm happy to buy the 36v bbs01b I think, I don't think I'll need the extra torque.

Is the danger here that the battery will supply more than 15A and destroy the controller? I thought 15A was the standard for a 250w bbs01b? Surely I don't need the battery to deliver 25A continuous when the controller will never draw more than 15A?

It says the motor controller is rated to 15A

£476 for the kit 17.4Ah Chinese cells Or £568 for the kit with 21Ah LG cells Is it worth paying extra here. I've also got no idea if the BMS is any good

Greenergy on Aliexpress inform me that they can ship from the UK so there will be no customs or vat to pay. This seems to be a good option only I am concerned about the quality of the battery? Is a cheap battery from AliExpress a bad idea? They can sell me the bbs01b kit with a 17.4Ah battery for £476

I think you are correct actually. I think I would be liable to pay 20% VAT in top of the initial cost bringing it to £637.20. Is there any saving to be made from purchasing from AliExpress/eBay/Amazon or is it better to just purchase from woosh or eclipse?

I've seen PSWPower have an ebay store. I'm tempted by this kit: https://www.ebay.co.uk/itm/255123631335?hash=item3b668dace7:g:6B8AAOSw7PljbJT7 Does anyone know if this battery is a good safe option, mostly concerned about potential fires: HAILONG-PLUS 36V 20AH Specification: (3A charger) 4P10S Li-ion 5Ah 21700 40pcs battery cells (the interior battery is SAMSUNG INR21700-50E 21700 Li-ion battery) Additionally, can anyone recommend a good display? I'm looking at SW102 currently based on price/looks. Other choices are P850C, P750C, C965A, DPC18 and 860C.

Is this a good price for a bafang bbs02b 48v 750w It's from the Bafang erider store that is linked on the Bafang main website. I'm hoping to buy any bafang mid drive kit for the lowest price possible. Any advice would be appreciated.
