Hello,

We are developing this BMS:


It is very small. Main features today are:
* Supports 5 to 16 cells.
* Balances up to 150mA.
* Does not need external power supply.
* Onboard FETs and current sensor up to 150A.
* Supports external current sensor up to 750A.
* Supports external contactors for load and charger.
* One onboard and two external temperature sensors.
* USART/USB/bluetooth/CAN communication.
* All voltages, temperatures and current are configurable via Windows app
* Status LED, buzzer
* Programmable inputs and outputs: heater, FAN, AC sense, contactor drive, ignition/enable, speed sensor input.
* Calculation of SOC and remaining distance.
* Onboard 5V DC/DC for bluetooth, current sensor and CAN isolator
* Tracked statistics, event log, bootloader for free firmware upgrades.

More info available here: https://www.energusps.com/shop/product/battery-controller-s516-150a-750a-36

With this post I want to ask you, DIYers, what other features should we implement for the product to be more attractive?
Currently we have feature request:
* More series cells or stackable solution.
We are working on that. But is there something else missing?

Hi everyone. Just a short update: the product is a success! Is actively selling for 6 months now and no major issues reported. Firmware is constantly updated, everything is going well. We are out of stock once again, but new batch is coming soon.

It supports batteries up to 16s (80V max), current up to 750A, can control external relays. Also Eltek CAN support is coming soon.

We also released battery modules with 18650 cells of highest energy density yet. Best one so far - 228Wh/kg.
For example, 20 kWh = 88kg.

Some of these modules are being used by electric formula teams, which is a good sign.
