This works for 10S (or 11S), but is one pin short for 12S. I personally use one and I have seen use one. The SP21 IP68 connectors have up to 12 pins.

Many people use 12S batteries and that means routing at least 13 wires outside of the enclosure if you want to measure individual cells or balance charge. Let’s first have look at how it can be done. Routing balance wires outside of the enclosure opens many possibilities, such as using a balance charger or check cell voltages manually with a multimeter. I don’t know these, so I’ll just put the links here (thanks Neptune 15

It comes with a very cool looking Android app with a ton of features. Neptune Lite is a BT enabled cell voltage monitoring module with a very small footprint (41x35x7mm). Doing some experiments with this is on my TODO list.Īnother option that suggested is using a BMS chip without the BMS components not needed for voltage monitoring, which would likely result in a much smaller device than a traditional BMS. One option I discussed with in another thread is using a simple voltage divider along with ADC module with sufficient resolution/accuracy (possibly the ASD1115). The question is what would be the best way to create such module. Some say that the li-ion batteries don’t require balancing, though keeping an eye on cell voltages is recommended. The ones with li-ion packs who like to live dangerously could even skip the BMS completely. Similarly as the Smart BMS, it could be hooked up with DAVEga or with Arduino + OLED display or with ESP32 + Blynk. This would likely be a tiny module, much smaller than any BMS. It would be really nice to have a module that only does one simple task – read individual cell voltages and communicate the values over UART or I2C. We could also try to convince to integrate the LLT Power BMS with the Metr Pro, which doesn’t seem that hard to do now that the DieBieMS integration exists. I believe it can be done in less than one day. With ESP32 board and Blynk, an iPhone app for cell voltage monitoring would be easily available. If you don’t know Blynk, do check it out. I managed to get it working with an Arduino, or more specifically, with my DAVEga hardware, which is essentially a simple Arduino with a display.Īlso, the Smart BMS could be hooked up with a WiFi/Blueetooth enabled development board (ESP32 and ESP8266 dev boards are cheap and widely available) along with a simple mobile app in Blynk. The smart BMS comes with a UART port and the communication protocol is somewhat documented (though deciphering the documentation is only marginally easier than reverse engineering the protocol ).

The software configuration is straightforward.

It requires a PC module, which costs additional ~$7 and the software only runs on Windows. It can be relatively easily re-configured (I have done it) for a different number of cells. It’s all the same hardware, which comes pre-configured for a certain number of cells. It only makes sense to get the 20A as charge only. Probably not enough for e-skate application. There are three versions – for 20A, 30A, and 60A discharge current. There’s also a number of configuration options. The UI is by far not as polished as the Metr Pro, but it does provide all the info anyone may care about. An Android app that can display cell voltages as well as other useful information is available.

Relatively cheap Chinese Smart BMS that supports UART communication and comes with a bluetooth module. DieBieMS is currently not easily availableġ.2.DieBieMS can be used as charge/discharge.tech support (products of active community members).

It integrates with the Metr Pro module, which can route the DieBieMS data to your mobile phone. DieBieMS is a smart BMS that supports various communication interfaces. Great products made by community members. These probably don’t need any introduction. The information is either wirelessly transmitted to a mobile phone or is viewed on a display that is a part of the enclosure. The cell voltages are measured by a device sitting inside the battery enclosure. Possible solutions can be divided into two main groups – measuring inside the enclosure and outside the enclosure. I also hope for people to chime in and help to complete the list. I’ve been looking into what options there are. If nothing else, knowing that your cells are well balanced and don’t tend to drift away will give you a piece of mind. I believe there’s value in knowing the voltages of individual cells (or P packs) in a battery pack.
