BMS For 16 cell, 48v volt Lithium-iron-phosphate DIY batteries.
100 amp continuous charge or discharge current.
Low Temperature Charging cutoff at 0c.
The Apps allow you to monitor SOC (state of charge), Current, Voltage, cell balance, temperature, and more.

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

If you choose to add crimped copper lugs, the high current wires will be hydraulically crimped into a single tinned copper lug on each side, and finished with heat shrink tubing.

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

To view or change Parameters, there are 3 ways to connect to the BMS.
1. Bluetooth module to IOS app. The app is on the Apple app store, it is free to view operational data, but costs $6 to view and change parameters.
2. Bluetooth module to Android app. (download this version, don’t get it from the play store)
3. USB module to PC/desktop application. This application is free

IOS app is on the Apple app store. Search for “xiaoxiangBMS

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.

    I love that there’s a large color instructions sheet with this unit. Made install super-simple. Bluetooth has worked great and I did the paid upgrade for the iPhone app so I can change settings as I see fit. Booted right up, no problems at all.

    I waited years to buy a BMS for my system. I wanted something that would show me individual cell voltages, allow me to change cutoff parameters, had proper high and low temp cutoff, and let me control it all via Bluetooth. #OverKillSolar FTW

    I am quite new to DIY batteries, but having tried an aliexpress daly bms, this overkill 48v bms is packaged much more professionally. Main metric I use to prove the quality of this unit is the lack of voltage drop across BMS when checking total battery voltage. The daly bms read 9.6v for a 4 cell 12v DIY battery which is >13v when bypassing the daly bms. Overkill showed no loss at all. Bluetooth works great. Haven’t tried usb PC connection yet.

    This BMS is everything its cracked up to be. Instruction are easy to follow and it preforms as it should. This was my first DIY lifepo4 battery and its running perfect because of the instructions. Thank you gentlemen. I will be ordering a few more in the near future!

    Just got my 16S! It fired up and worked great. Great Bluetooth communication. Some of the best quality I’ve seen from china. USA based Overkill provides the added detail that you will likely not get from overseas. The one page colorful instruction sheet gives you extended comfort that if you do something wrong, you’re not stuck with it. You just call customer support.

    Solid bms but it would sure be nice if the 48 volt had the M6 connections that the 24 volt has.

    I have been running this BMS since October and I am very satisfied with it. The BMS operates flawlessly and the app allows me to monitor and adjust all of the set points. (Android). I am running 280 amp hr BLS cells with an Outback Flexpower 4048 .
