    Anyone working with the Overkill Solar Arduino lib?

    Just in case anyone wants one, I uploaded my PCB design and the ESPHome code to GitHub. You can have JLPCB make the PCBs and they will put on all the surface mount stuff. https://github.com/porchthecoder/OverKillBMS_ESPHome

    They look good. No errors. Let me know if you want any.

    I just ordered the above. Let me get them in (about 2 weeks) and check for errors before sharing.

    Xiaoxiang's "Charge Balance" / Overkill Solar's "Balance only when Charging"

    Based on what I am seeing in my batteries, the small mount of discharge current the Overkill uses to balance the batteries is basically doing nothing. I am adding a Heltec to all my packs.

    Anyone working with the Overkill Solar Arduino lib?

    Nice Grafana graphs. I like the hours remaining. This PCB was a "lets bang it out quick because there will always be a revision 2" style prototype. So my picks of components was based on what I could get designed and made quickly in EasyEDA/JLPCB. There seems to be two types of ESP32 dev...

    Active balancer or not?

    I added the Heltec S16 right at the 13:13 mark. I guess it's working.

    Anyone working with the Overkill Solar Arduino lib?

    Current ones are taken, but I plan to make a few more. I don't need any displays as ESPHome feeds it to an MQTT server, and that spits it to Grafana. And the battery packs sit in a plastic tub. But I was thinking of adding some LEDs. I can add some pins for a display to the next batch if you...

    Anyone working with the Overkill Solar Arduino lib?

    Ya, I made the PCBs. I have a few packs I want to monitor so I didn't want to hand solder that many. I was having an issue with the old library reading low voltage on everything. New library fixed that issue. The new library does have bug I fixed around type casting of min, but that just might...

    Anyone working with the Overkill Solar Arduino lib?

    Thanks. After a bit of fiddling, I got the https://github.com/FurTrader/Overkill-Solar-BMS_2-Arduino-Library library imported into ESPHome and got it working that way.

    Got it figured out and working with ESPHome.
