Hi, newbie to bluetooth bms and still havent read whole discussion, but: Has anyone come up with a way to increase range for the bluetooth? I tried to mount this bluetooth on multi rotor drone, to properly see voltage levels, but the 'reception' is so bad, that the connection gets broken apart after...

Re: Samsung SDI cell - 22Ah - EU - Austria - LiFePO4

Yes but 4 cells not enough, I guess for 12v operation it would work but I was planning ebike build, would need at least 14, and even then I guess 30ah would have been more desireable

Re: new-old build

Just wanted to comment on this awesome build! Even though this topic is already quite old, wanted to comment how nice and clean it looks and takes up very little space in the middle section of the bike. Been planning to do one on my own (Rc 'mid drive') and drive the rear wheel on the other side, wh...

Re: Samsung SDI cell - 22Ah - EU - Austria - LiFePO4

For what power levels are they designed? Can they output 3C (66A) continously?

Some clarification would be nice, a bit tight on budget so these would go as 1p config

Re: Nice 5:1 gearbox

Mh yes, Im still not sure how to mount external / extra sprocket on the rear wheel anyway. The current bicycle has disk brakes (dirt / jump style frame) so I would either need to remove them or somehow make the gear larger while still retaining the brakes probably (unless regen braking would be very...

Re: Nice 5:1 gearbox

So are there any more projects using this 5:1 gearbox? Im also considering using it but what I dislike right now is that it would be placed on top of wheel, most likely. That is because most bike frames dont have enough space between rear wheel and triangle frame and fitting inside triangle seems li...

Re: Electric downhill/freeride bike

Sorry to open up old thread again but I suppose u got the bike running. So what power levels do u see while riding and does each 80 turnigy pump out these 5kw of power? I guess for riding on flats a lot less power is needed,.would say up to 4kw for constant speed? Otherwise your 1+kwh battery would ...

Re: Unite/Currie MY1018Z: How many amps do you shove in?

Ive just started experimenting but it does see like this motor loves to eat watts/power. I got the 24v version and hooked it up to 36v li-ion battery. Speed is decent, close to/around 40kmh with not fully charged battery. Had some chain alignment, motor plate fitting issues but now it.seems to.bette...

Friction Drive - kits from Aliexpress. Any Good? Has anyone Tried them?

Hi, there seems to be 3 varieties worth looking at. Most of them come in price ~200 - 400 eur, depending on shipping cost / customs tax, which might be added on top of order. This one seems to be most promising, also boasts 36v and 500W of power: https://www.aliexpress.com/i/32965870432.html -------...

Re: My excellent adventure through some battery builds

Looking good. Looks like you are progressing battery wise..

Would be interesting to find out how much the final weight is for your scooter with different battery configuration. As you said lifepo will be heavier but how much more?
