Smart BMS 7S ~20S 300A Li ion Lipo Polymer Lifepo4 Lithium Battery Protection Board Bluetooth APP 8S 10S 13S 14S 16S 24V 36V 48V
for 7-20 battery packs of power batteries, electric bicycles, electric motorcycles and other products; it can be applied to lithium batteries with different chemical properties, such as lithium Ion, lithium polymer, lithium iron phosphate, etc. The protection board has strong loading capacity, and the maximum continuous discharge current can reach 300A.
● 7~20 strings of batteries are protected in series, and the number of battery strings is automatically identified.
● Vehicle-grade analog front-end chip, high voltage acquisition accuracy, safer and more reliable.
● Various protection functions for charging and discharging
● The power switch is a relay with high withstand voltage and more reliability.
● Accurate SOC calculation, with automatic learning SOC function
● Bluetooth communication function.
● Reserve switch to control the output of the protection board. With the discharge switch, the pre-charge function is available to prevent lighting.
● When the standing time reaches the set value (parameter setting page switch time), it will automatically shut down and sleep, reducing standby power consumption.
● It does not support the direct parallel use of battery packs (battery packs are directly connected in parallel, and there is a problem of high-voltage battery packs discharging high current to low-voltage battery packs)
