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...

Re: 18S LiPo Wiring diagram

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?

Re: 18S LiPo Wiring diagram

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...

18S LiPo Wiring diagram

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?
