Q4. Which type BMS should I choose?
A4. The current marked on the BMS is the continuous discharge current, not the capacity of the battery, the continuous current of the BMS needs to be greater than the current limit of your controller, if you choose to buy small will frequently trigger power off protection, and even burn out the BMS, such as your equipment controller current limit 30A, it is recommended to buy a 40A/50A
board , the protection board buy large or not buy small.
Q5. What type of charger should I choose?
A5. Lithium battery must choose the corresponding model of charger for lithium battery, do not use lead-acid battery charger, because lead-acid charger may have MOS tube with high-voltage breakdown BMS, thereby damaging the BMS and causing it to not work.
