If I can find this 12v cable for cigarette lighter I can charge the jump starter from my 12v side of the system. Guess what? I found the USB C wire that they use to charge this thing with. Sorry for the bother. I just plugged it into a laptop and it should be okay. Thanks!

I bought this jump starter from Amazon but it did not come with a charging adapter and now that I need it, its dead. http://tinyurl.com/mtwpjdbp

24v

Is there a device I can buy that would utilize the power in my battery bank via inverter to jump start my car battery?

I use my Motorola android phone to monitor by bluetooth and this USB device to monitor with my laptop: https://overkillsolar.com/product/usb-module-for-bms/. Seems to work okay.

In the screenshot above the batteries show zero amp hours and discharging. Today the batteries show 97% and 98% amp hours at about 27.95v and discharging. I turned off solar panel input at a breaker to the solar charge controller and the discharging stopped. Wonder if the BMS is discharging...

Those are your words, not mine. Try the easy "some tangent" first and before disconnecting the battery and "dealing with it," is all I'm saying. Here is what I'm talking about. The attachments are from the USB modules, one for each 8s BMS, and this software shows 71% battery capacity. Not...

Sounds like a big job. Wonder if the bluetooth connected software is accurate. I will try the USB connected module and its software and see if there is any change and go from there. This USB device: https://overkillsolar.com/product/usb-module-for-bms/.

I have two 8s 100A Overkill BMS's on (16) 3.2v 100aH LiFePO4 cells in a 24v battery banks. The inverter is off, there is no load on the batteries, the remote monitoring display MT50 shows the batteries charging (see attached). The MT50 shows a charged battery. The software shows zero amp...

I've got some spare panels 250W x 4 and 100W x 4, a couple of Battleborn LiFePO4 100aH batteries and five 3.2v 280aH LiFePO4 cells (in various conditions, some swelled), plus lots of wire, breakers, etc. What is the best way to utilize the extra solar panels? Or, what would make an interesting...

Summer of 2023, hottest year ever recorded in history. I'm running a Sennville LETO 9,000 BTU A/C and Heater off of 560Ah battery and three solar panels mounted on ladder racks on my Ford E-250 van. The mini-split is mounted on the left rear bumper (facing the rear). Batteries appear to stay...

Mostly, nonexistent but I can follow directions.

Do you recommend the ESP32 DEVKIT DOIT board? Not looking for another project or rabbit hole, but a kit and straight-forward solution to monitoring devices would be interesting. The Home Assistant sounds interesting.

And, hook up to Teamviewer or RemotePC and work the controls from your remote computer that's connected to the USB device. That should work.

Wonder if someone has put a DIY "kit" together that controls access to the BMS's? I have great bluetooth access via the Overkill BMS's when I'm next to the battery with my Android phone, just not when I'm in outside of bluetooth range.
