sensor:127]: 'jk-bms charging low temperature recovery': Sending state -10.00000 °C with 0 decimals of accuracy When a battery is discharging it will draw voltage down and the Inverter should be set to stop Inverting at about 46V to 48V (2.875V to 3.0V per cell) The UVP and UVPR are used to set the BMS to shut down on Under Voltage so as not to let the battery be discharged until damage occurs. It should be set at about 2.6V to 2.7V and UVPR should be set about 0.1V higher. 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. Using these guidelines will not only save you on wiring costs, but it will also save you money on a BMS and a charge controller. 4S BMS LiFePO4 Diagram

Passive balancing will remove or add capacity from a particular cell and dissipate it as heat. Active balancing takes the excess from one cell and delivers it to a cell with a lower voltage. Active balancing has fewer losses -and is thus more efficient. read more about passive and active balancing here. What size BMS should I use? takes a long time but it keeps cells balanced perfectly. I can use 80% of battery capacity and be confident it will stay balanced. But, a passive balancer could probably do that too. I love how it balances the cells perfectly whenever charging stops. It does even better when ever I am floating above the balance trigger. I am starting a thread specific to he Heltec 200A Smart BMS with 2A Active Balance. 200A max charge. 350A max discharge

This BMS has a continuous discharge current of 100A and a peak current of 165A to 200A, which is simply an insane amount of power. This BMS has settings to adjust the overcharge and over-discharge protection levels, which is super nice. I cannot stress enough how easy it is to use the JK BMS app. Everything is where you expect it to be, and everything makes sense. These BMS are pretty powerful, however, and can do 300A for 5 seconds. Also, once you get them setup and working, they are reliable. The setup process is just not the most intuitive and again, the app is not very well designed. Through the software, you can set the parameters of the active balancer to ensure battery balance and extend battery life.

Choosing the best BMS for lithium and LiFePO4 batteries can be a challenge if you are not familiar with all the terms and with so many brands on the market that all claim to be the best. JK BMS, JBD Smart BMS, and DALY BMS are the best BMS makers out there, but this article reveals that there are levels to that, too.

Mobile App Compatibility

DALY BMS has a much better app than JBD/ANT, but does not offer active balancing built in. This, however, is sometimes a feature as active balancing is not needed for every application and certainly adds expense and bulk to the BMS.
