Acceptable drift between cells

It’s set up to static balance so it’ll balance as soon as the cells vary by more than 0.01V

My BMS has had yet to activate its balancing circuit, which is how any well designed pack should be Imo. If you are constantly having to balance your cells something is probably wrong Imo.

Badass app. I’m such a noob I didn’t even know about these Bluetooth bms you speak of.

I’m honestly surprised you don’t see them more often there’s maybe half a dozen ppl using them that I’ve seen.

Using charge only 10$ BMS’s scare me lol.

I was originally gonna run BMS less before I found these.

On any bestech bms that is used the most on here, balancing starts as soon as one of the cells hit 4.2

I do not know any bms that is balancing all the time can you link me one?

Ohhhh boy I got create a thread for this shit lol https://m.aliexpress.com/item/32827750823.html?pid=808_0000_0201&spm=a2g0n.search-amp.list.32827750823&aff_trace_key=63c1f9c951c34dbe8b96f4548590dce1-1525552980071-09079-7M7IEmQnY&aff_short_key=7M7IEmQnY&aff_platform=msite Capture%20_2018-08-04-11-41-27

Those are just the basic settings available for the app the pc app let’s you change about 20x more settings lol

This is the 12s version I used well it was from a different seller http://s.aliexpress.com/zU7B3yiM Same kinda idea it’s all based off of these designs from https://www.lithiumbatterypcb.com/3s-to-30s-lithium-ion-pcb/

They are the original designer as far as I can tell and have customizable options for ordering whatever you could need.

Wow thanks. I don’t know how I overlooked these when searching. I’m looking at a high discharge and it looks like this might work.

Just so everyone knows there is no iPhone app currently so android only.

Those are even a step up in some ways supporting whatever battery config you want. But they are quite large /pricy. You can get up to 100Amp discharge BMS’s of the same style I added a link to my previous comment of the exact one I’m currently using.

Tho I’m only using the 80Amp model

Awesome. How do we get it?

Damn what bms/app is that.

As far as I know someone could write a much better app for this and it shouldn’t be to hard for android but good to know someone made an iPhone version.

They are temperature sensors!

Just found this one

A bit more expensive but works from 8-24s and up to 300a.

Lmao what do you need 300A bms for? thats the real question.

Nu who knows :joy::joy::joy: if I wanna fly to the moon… No, seriously, if I wanna go quad mountain board I need as min the opportunity to go 150a. 300 is over the top but one day with 24s…:joy::rocket: Need to find the right esc for it🤔
