Thanks drdrs for the review!

I’m in Canada and had found that hilleater.ca was distributing them, found here:

https://hilleater.ca/bms/

and here:

I saw your post about the Arduino display coding, thank you very much for creating and posting saves a lot of time and oh yeah sometimes frustration trying to get a code to work properly.
It is really nice to be able to see all cell voltages at a glance. I do have a spare Arduino sitting on the shelf!

Is the BMS still balancing at 10mv? It doesn’t really matter to me as I charge to 4.10v, just curious.

Thanks for the tip on the B- soldering.

Currently I have the BMS set to start balancing at 3.5V, finish charging at 4.1V, and tolerate no more than 15mV max-min difference between cells. I charge with a meanwell hlg-320H-54a CC-CV tuned so that the current drops to the 1A BMS cutoff at the same time the cells are reaching 4.1V.

When the charging is finished, I see 10mV max-min differences, better than the 15mV setting.

Looks very nice ....is it only Tiny BMS compatible ....or can it work with other Smart BMS units? Also ....how about a link of where it can be purchased?

Has anyone else found a small real time display to work with the Tiny BMS? I emailed the seller/distributor from their web page and never got a response. What is support like on these currently?

I'm not aware of a display besides the LED SOC one by Energus. I decided to build my own that talks to an ASI controller and the Tiny BMS using an Arduino Mega and a TFT display shield by Adafruit. I'll get around to posting it in the next few weeks.

Would love to see that ... that post from DaDo.Bzz is interesting but I have never received a response regarding where to get that display.

Hehe, it's called "maybe support." Those guys don't seem to be too interested in feedback and improvement of their product. They'd rather "sell and forget." How long ago did you contact them ?

I used their messaging on the web page ...so no record of exactly when ...but I believe it was about a month ago. Certainly seems like support is no support at this time.
