The QUCC is a BMS that uses a relay instead of MOSFETs to break the circuit. This results in the cost being lower, but that doesn’t make it more reliable. sensor:127]: 'jk-bms total voltage undervoltage protection': Sending state 3.77000 V with 3 decimals of accuracy

The Inverter is the means of control, its the device that cycles between battery Charging and supplying power (Inverting/Discharging batteries.) 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.In an ESS mode, the BMS simply tells the Victrons when to start and stop charging with the DVCC settings under the ESS tab. Wiring a 4S 12V BMS is quite easy. The BMS has two cables. These are the main battery – and the main cell -.

Therefor I am looking at REC who is- out of the box – a better match with Victron. Probably two extra Victron MPII’s will be added including the existing ABB XT4 power surge protector (325 Amps) that can be triggered by a 48V voltage on it’s disconnect coil. Also, most BMS on the market provides no way for the user to monitor the battery. It's very important to be able to see your individual cell group voltages and be able to monitor the amount of current going into and coming out of your battery. Our warranty does not cover items that have been damaged due to gross negligence, normal wear and tear, damage due to accident or collision, abuse or incorrect installation. I will have to say that the JK BMS is the best. It has a high build quality, can work with 7S to 20S, and can work with both lithium (NMC) and LiFePO4 (LFP) cells. The JK BMS is the most versatile and has the widest range of configurations. It also includes active balancing. The JBD Smart BMS is just as reliable once you get it going, but setting it up is less convenient. It provides active balancing and is definitely a great BMS, but without having an official app, JBD will always be a few steps behind.With 18s you will use the maximum voltage of the inverter and will have more power available by just adding two cells.differs almost 3kWh of extra storage with two strings. It will reduce the amount of available BMSses though… sensor:127]: 'jk-bms discharging overcurrent protection': Sending state 60.00000 A with 0 decimals of accuracy sensor:127]: 'jk-bms total charging cycle capacity': Sending state 0.00000 with 0 decimals of accuracy By setting the active balancer, you can prolong the battery's lifespan and reduce the frequency of battery replacement.

With real-time parameter display, you can timely understand the battery's status and use it reasonably, saving energy. sensor:127]: 'jk-bms temperature sensor temperature protection': Sending state 100.00000 °C with 0 decimals of accuracy 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?The "Allowable Voltage Range" for LFP starts at 2.500 and ends at 3.650 Volts per cell. There is No Harm/Damage cause when the cells remain in that range. Go Above or Below and you're causing harm. LFP Has a Low Internal Resistance compared to others and as such can put out a LOT of juice in a burst. The BD6A24S12P Active Balancer BMS has a working voltage of 20~100V, making it suitable for a range of applications. With advanced features and cutting-edge technology, the BD6A24S12P Active Balancer BMS is the ideal choice for those looking for a high-quality lithium battery management system.
