So where do I get a new battery from then. AliExpress was last place I got one. But now it seems they are charging tons of shipping extra. Also what do I now do with the battery I have now

You got any cheap places lol

So really then I would need to buy a new battery from ERider which I think is £320 I paid £350 for the moped but I suppose like flecc said there isn’t many bikes at approx £700 it just annoys me. That I didn’t check battery at 1st at sellers house. But how could I have done that. Also I don’t...

Ok many thanks will give it a try soon

When you say Panel do you mean where the battery case is fitted to access controller box. Wow so that key slot is to lock back brakes. I get loads stuff from AliExpress that's where I bought my lithium battery for my electric bike thanks to you guys. so its only £14 but I wont have a clue how...

Yes someone also said about the Controller, but I wont have a clue where that is located on the ERider model 15 maybe I should contact ERider again and ask. yes once the dc jack plug arrives from Ebay I ordered I will only then charge battery in that plug not the 3 pin no more. what I find...

I also just like to say many many thanks to all you guys as you all are and have been so helpful I can remember when I bought my electric bike which had 2 x 12v SLA batteries on it and you all helped me replace with a lithium one and its still going today, But I will be selling it once I get...

Well maybe later on I will invest in a bigger battery, but to be honest I wont be going on very long journey's its just to pop to shops etc I have now tried another tester I have and it now reads 54.5 on the charger so better now. I think I had it on correct setting by the images below. so do...

so you mean test those 14 pins what vfr said but use the 20v mark on meter. which like I said above I only tried 1st 3 pins and they just say 1. nothing else was I correct then. also does this battery seem ok then to you all

Hi Im really confused now what you mean by this what you mean sewing needles, and tape them to the multitester prob ends. and what pins do you mean the same as I have just tested can you send some pics what points i touch Hi Nealh I have now again tried testing those pins there is 14 of...

Hi I am very grateful for everyones help here its most appreciated believe me I have learnt loads so far. ok I have now tested all 14 pins again and its this is starting from 1st pin. 14th pin there is no reading ok 52.1 48.1 44.1 40.0 36.0 32.0 28.0 24.0 20.0 16.0 12.0 8.0 4.0 thats...

so these in ebay link are what I need to fit the socket and how do I tell on charger which is neg wire and pos wire or will they be red black when I strip outer case off if so then I know red is pos and is this in image the correct dial on meter to test Yes I think that dial on meter is...

its so awkward to measure BMS pins using B- and I set it to 20v setting as in image below I have now just tried 2 pins and all they read is 1 . but if I turn multimeter dial to the V 200 mark and then check pins 1st = 52V 2nd= 48V 3rd= 44V 4th=40V 5th=36V 6th=32V 7th=28V...

So what about what setting I put multimeter on to check those BMS PINS plus what setting to check charger pins

Hi I thought the 3 pin socket was the discharge socket but now you say don’t put a DC Jack plug at end of charger they can’t be that hard to solder just 2 wires to the Jack plug. I don’t think the 2 wires on the charger are that thick. Also I live in a 1st story flat and have a shed on ground...

Hi I really appreciate your help and also others here too. I’ve learnt loads. I will tear a bit more to show the bms connections you asked. You say switch on the charger and measure voltage between the 2 outta pins I take it you mean that kettle plug on charger . Can you just tell me what...

Dam the bloody seller was even charging it from that 3 pin kettle plug on charger. can you not get an adapter for that 3pin to a dc jack then or am I going to have to buy now another charger with a dc jack on end. so I take it the charger I have is fine but need a DC socket at end instead of...

Hi yes just got home after dam walking moped back, I didn't go very far so not too far to push it home. its defo a wiring fault somewhere or loose wire. as when I was on way home. it kept like cutting out. go 2 yards stop etc. then I noticed on dash nothing at all. I have now just tested...

this is that 3 pin connector on battery case and also the single black wire one but don't know what the single one is for as I use the 3 pin connector to charge batt.

That 3 pin connector must be to charge battery, as today battery said 52.1Volts and I have now plugged in that charger what plugs into the 3 pin socket on batt case, and battery now says 53.2Volts so its defo charging it. I still cannot see what you mean about that single Black wire. what go to...
