I am starting to wire up my first ebike - I have a query regarding the wiring of the throttle - does it connect to PAS wires on Sabvoton 72v 200A?

I have tried this wiring configuration with my current BMS - I connected the 3 batteries together with the discharge leads, then connected the balance plugs - but when I connected pack 2 in it short circuited when I had the - wire into the + as per your diagram can you use multi-meter to measure ba...

Thanks Danny I will wait as I'm currently buying the parts at the moment. Will it handle 3 x 6S lipo? If so how do I wire these into your Neptune 20 - PM me if you have any instructions yes, all you need to do is make 3 6s pack in series >> 18s, and use Neptune 18s connector connect to Neptune 20 D...

Is anyone using a Neptune 20 lite with 3 x 6S LiPo batteries? I am thinking of buying one but want to ensure it will work with 18S Lipo made up of 3 x 6S Lipo Can you switch on BMS to charge only and leave turned off when riding or do you leave on while riding - if so what is the current rating for...

None of those diagrams are right.

I'm pulling my hair out trying to work this out! Any advice is very much appreciated

Should I include the negatives of packs 2 & 3 into the BMS wiring?

I am wiring the packs in series so if I connect the negative balance wire of pack 2 to the positive of pack 1, as well as having the discharge leads wired for 3 packs in series I would get a short circuit?

The voltages are not true as I have charged and balanced them with my Thunder Power charger. Admittedly these are older packs I'm using to test the BMS with, so if it goes wrong I dont mind! I was planning on using 3 x 6S lipo maybe 10000/20000 mah depending on space in frame I might have to scrap t...

Eventually got my BMS and wired it as per their instructions - here is the diagram Here is a screenshot from the BMS app Can anyone shed some light on this? I have tried different wiring combinations but nothing seems to work

Look at my post - looks like we both went wrong!

Thank you dogman dan for you guidance

So my balance wire harness should look like this? Just waiting for some female JST-XH 6S connectors coming and I'll get it soldered up ready to test

Just wondering what size wheels and tyres you guys are runnig? Ii am looking at buying QS 205 laced into 19" x 1.6" moped rims, but don't know what motorcycle tyres will fit this size! Would 2.5 fit onto the rim? I am planning on using my E Bike for commuting to/from work, so mainly tarmac...

Does this look right?

I am going to be building an E-Bike and have just ordered a BMS. I am an R/C Modeller so I have loads of 6S LiPo batteries which I plan to use in an 18S setup.

Below is a diagram from the BMS seller and a blank wiring diagram as I am unsure how to wire it up

Could anyone offer any advice?

I am thinking of building an ebike with a stealth frame from ebay / AliExpress - I am looking to see if anyone has fitted Turnigy 20000mah 6S Lipo batteries into these frames and how did they wire them. I am looking to use it for commuting to work and forest trails in summer. Also what kw motor woul...
