With the spring air coming, it's time for some refreshment: the HW update of our best-selling BMS123 Smart – Gen 3. Check the product page for more details:
Main features of the update:
✔️ LTO compatible ✔️ Operates on cell voltages between 1.5 V and 5.0 V ✔️ High accuracy SOC
When balancing my pack with BMS123, I noticed the boards get very hot (some +65°C). Is it OK?
Firstly, for large size battery banks and for cells that have become disbalanced, we strongly recommend avoiding long time balancing. The suggested solution is to charge the cells individually with a single cell charger.
Question:Can you give me the information about the access data for the BMS communication protocol? I wish to access the data from the BMS in raw format. Do not worry I am a programmer.
Answer:The BMS using standard wireless Bluetooth technology witha proprietary communication proto
Question:Will BMS123 Smart send out signals to my inverter as needed? (E.g. CAN open high and CAN open low.)
No.The BMS123 Smart does not support CANBus itself. The reason is that the BMS itself is a low power device. The operation of the CAN bus requires continued drain from the batteries,
Although making „a better BMS123“ was not our intention (our CPM is simply a different product), we respond to your questions regarding a comparison between the two.
Anyway, the +/– are yet going to change as we have big development plans with our CPM! Stay tuned.
(Cell Performance Monitor)
If the positive (+) hole on the cell module is too small, you can make this hole bigger, the boards are designed to be drilled bigger if needed.
Make sure to remove the drilling dust afterwards to prevent short circuits or other unintended behaviour.
A good way of doing this is indicated on photo.
Please be aware that your battery-pack contains a large amount of energy, which can be potentially dangerous. Use isolated spanners, to prevent any short circuits.
High inrush currents, causing arcing (sparks) and ultra-high electromagnetic levels, can easily damage electronic circuits.
We therefore strong
