About BMS
This BMS product is for customers who have bought lifePO4 batteries. If they choose and buy BMS suitable for them under the advice of the seller, we will send them out normally.
Special case: If the buyer did not buy the battery from LANpwr, but only bought the BMS, please confirm that the BMS is suitable for your own battery before purchasing, and we will not take any responsibility for the buyer's wrong purchase.
