Thanks guys, thought it would probably be a ≤25A controller. Does look like dishonest seller, hopefully they didn't know something I don't about the motor! However the eBay seller was 'The Bike Shop Wales'. Seems odd if a reputable bike shop mini-chain would bother selling dodgy second-hand...

Great advice, thanks. Still wondering about controller power though. So it makes sense that nominal wattage isn't particularly relevant, but still in terms of current do I want to shoot low or high? BBS02 750W is 25A so I'm wondering if I get a 13A controller, will the motor pull more current...

Yikes, multiple er30 blown controllers doesn't sound fun! Can we not get to the bottom of what's going wrong on the controller? There's plenty of info on swapping FETs online, if only an electrical engineer would solve this problem for us! My thought re external controller was cheap eBay one. I...

Cleaned up the silicone, also left it all in front of a dehumidifier for a while because I read someone else's worked after a drying. No avail. I have been looking at an external controller solution. Trouble is, I've invested in loads of Bafang parts now. Think if I had known about the external...

Cool, yes, I have seen these. Will try to relocate tomorrow. Er30 is displayed just the same with the controller loose from motor. The display comes on showing no battery for one moment then goes off with Er30 in the corner. By the way, can you program BBS loose from Motor? Also, does it need...

Thanks for your reply. Don't understand what you mean by "not full home in controller" though. And which connector is the JST? Cheers.

Hi all! I didn't give up on my BBS02 in the end... I negotiated a partial refund from the seller and we settled at that. I like fixing things, at least if and when I succeed! So I proceeded to order the other bits I need, hoping to diagnose the issue. All hooked up with display (admittedly a...

Ah OK. Haven't come across any second hand kits. Where have you seen them? Would have been about £200 all in for the kit so not a huge saving on 250, but still a good deal if it had worked like advertised and much cheaper than new. Guess I'll be looking for another second hand kit/motor now then.

I applied 3v across throttle and ground via an external psu. Again nothing with cranks still or turning. Pete, what exactly does 's/h unit' refer to?

Going to put 3v over throttle pin in a minute

Hi jarob. Sorry missed this at the time. Have tested now and no dice. Would really appreciate if you could check out the original thread and share any thoughts! Cheers

Hi guys. So I finally tried connecting power, jumping those two pins and turning the cranks today. Nothing happened!! I checked voltage across the pins and can confirm full battery voltage reaching them. Any ideas? Could PAS have been programmed out? Can I emulate a throttle easily? If it's a...

Very handy info, thanks. Hoping to get going on this very soon

Was your motor Bafang? To be clear, my motor isn't from Dillinger it's a used one from eBay. Glad to hear your battery hasn't let you down!

Thanks for advice guys. My battery is just 7.8Ah one that was going cheap. The cell spec. wasn't listed besides 'samsung'. The listing is here, though they're sold out now: http://dillengerelectricbikes.co.uk/spares/electric-bike-kit-spares/bafang-8fun-batteries.html Though not stated, a...

Hi guys, I recently picked up a used Bafang BBS02 motor and a new 48V battery to go with it. So thought I'd ask on here before I buy all the other bits from China if anyone has anything they want to sell. I need an LCD - not too fussy which one, wiring harness, brake sensors (want to keep my...

Ok, I see - thanks for that. Perhaps I should have consulted you guys before panic buying! But it still seems like good value per wh. No idea how long they've been on the shelf but regardless, do you think it'll suffice for 10miles of only moderate speeds/hills? Unfortunately I fear I won't be...

My thoughts regarding the battery were that it's a reputable vendor selling a new product with no caveats. I imagined it was reduced just because it's sold as a spare battery for a specific kit and I guessed they're just overstocked for the sales volume or something... Why, are you thinking the...

Hi guys. Been looking at getting a fairly powerful e-bike for a while. I like to be hands on so was looking at conversion kits but don't have much cash so felt like I was constantly window shopping. Batteries seemed prohibitively expensive, until last night I found this...
