A smart BMS connects to an app through Bluetooth, wifi, RS485, or a CAN connection. You can change the settings in the graphical interface. A standard or ‘dumb’ BMS is plug-and-play. The settings cannot be changed. What is the difference between a switch BMS and a relay BMS? Chengdu Jikong Technology Co., Ltd. is a high-tech enterprise focusing on the research and development, production and sales of lithium battery management system. Relying on high-power active balancing technology with independent intellectual property rights, the company is committed to becoming a leader in active balancing management systems for lithium batteries. I have 4 of them and I bought them from the Alibaba Heltec store here - https://www.alibaba.com/product-detail/14-24S-200A-Smart-BMS-with_62544207027.html

People often ask me what BMS they should get. A Daly or JK BMS. I always recommend people to get the JK BMS for the following reasons: Do you need a low-temperature cutoff? Having that kind of protection might be necessary if you live in a climate where it gets cold. sensor:127]: 'jk-bms power tube temperature protection': Sending state 90.00000 °C with 0 decimals of accuracy The BMS is not supposed to CYCLE, its a protection device not a control device. The concept is the same as the breakers in your load panel. They don't cycle on and off, you turn your appliances on and off as needed. The breaker only TRIPS if there is a short circuit.sensor:127]: 'jk-bms discharging low temperature recovery': Sending state -10.00000 °C with 0 decimals of accuracy sensor:127]: 'jk-bms temperature sensor temperature protection': Sending state 100.00000 °C with 0 decimals of accuracy sensor:127]: 'jk-bms temperature sensor temperature difference protection': Sending state 20.00000 °C with 0 decimals of accuracy

sensor:127]: 'jk-bms charging low temperature recovery': Sending state -10.00000 °C with 0 decimals of accuracy Some people say that DALY BMS do not do balancing, but this is incorrect. DALY BMS does not do active balancing without the addition of an active balancer module. This enables DALY to provide more compact, lower-cost BMS than its competitors. If you don’t get the active balancing module, the built-in passive balance current is 100ma.sensor:127]: 'jk-bms power tube temperature recovery': Sending state 70.00000 °C with 0 decimals of accuracy Also similar to the JK BMS, this JBD model can be configured and monitored over Bluetooth using the app. There is also a UART connection so the BMS can be hooked up to a PC using a USB to TTL adapter.

I hope to test a sustained discharge rate of at least 100A someday. My planned system would need changes for me to test higher than that and it could be years before I come to the conclusion that I need more amps. I don't expect that day to come but as I said I am new to this so I may change my mind someday.sensor:127]: 'jk-bms balance starting voltage': Sending state 3.30000 V with 3 decimals of accuracy sensor:127]: 'jk-bms total voltage overvoltage protection': Sending state 5.46000 V with 3 decimals of accuracy a) Before touching the PCB, the person performing the operation must discharge static electricity and take anti-static measures;

Bluetooth communication function, equipped with APP, to view the state of the battery in real time;sensor:127]: 'jk-bms cell voltage undervoltage recovery': Sending state 3.20000 V with 3 decimals of accuracy Someone asked me to do a review of this BMS. I am not really ready to do a full review because I am new to DIY batteries and it takes me a long time to test these BMSs thoroughly. I actually have only used one so far. I am just getting ready to set up a second one. The equalization current is set independently in the range of 0.1~2A, independent of the cell voltage difference; If you buy a ready-made battery, the BMS will be included. What is the difference between smart and dumb BMS? sensor:127]: 'jk-bms discharging overcurrent protection': Sending state 60.00000 A with 0 decimals of accuracy
