BMS For 8 cell, 24v volt Lithium-iron-phosphate DIY batteries.
100 amp continuous charge or discharge current.
Low Temperature Charging cutoff at -1c.
The Apps allow you to monitor SOC (state of charge), Current, Voltage, cell balance, temperature, and more.

This unit has a connection for a remote shutoff switch. Useful for storage or security.

Bluetooth Module is included, Balance wires are included, USB module is an additional purchase.
Fully programmable.

Final assembly, testing and calibration is done in Naples, Florida. Units with 8 gauge wires and/or crimped lugs are assembled in Naples,  FL. The BMS is manufactured in China.

FYI for experimenters: The BMS communicates with a 5v TTL UART at 9600 baud. It is directly compatible with Arduinos, etc.
We have written a new Arduino library for the BMSs, now available on the downloads page. The beta version allows you to read all the monitoring parameters and switch charge and discharge on/off. Future releases will have full read/write capability. A python library is also in the works.

    Do you want a great BMS? If you think the 100A current rating is good enough for you then you will not find a better BMS that I currently know of. This thing works as advertised and is built to last.
    I was looking for a BMS greater than 100A but then I realized, why do I need anything rated higher? My current system only charges around 80A max and I discharge maybe around half that 99% of the time as well.
    This BMS is fully capable of having you change any and every parameter you could want. I only changed my upper and lower cell voltage levels and the associated release voltages so that instead of the “factory default” values running the battery from 0-100%, I run my battery/cells from a 20-80% range. I checked this every day to make sure things were ok and now after a couple weeks I see that it is keeping my system safe so I no longer have to watch anything.
    I will be building a second battery so I will probably get another!!

    I seen the guarantee that said they would replace it even if we broke it.
    It sounded good but I figured it was only after a LOT of conditions right?
    Nope. I stupidly put the wires on backwards. I used the black as negative. Idiot move I know.
    Ok so I emailed Overkill and told them I needed a new one because I broke the other one. I explained what happened and he asked for my order number. I gave it to him.
    SHORTLY after this he emailed me saying he sent me a new one.
    I asked him how much it would be and he said free.
    I was flabbergasted to say the least.
    Some one that actually does what they say in their guarantee.
    I tell EVERYONE looking for a BMS [or whatever Overkill sells] to shop here and why I do.
    I bought other things since then as well. Love this place.
    I can’ say enough good things about a company that actually keeps their word. Wow freakin’ wow. 🙂
