Should i use a bms to balance my new lifepo4 battery before
If the BMS has no balancer, you need to balance your cells. A good top balance is preferable since you bought all 4 cells at the same time. If the BMS has a balancer and is rated at balancing at 2A, then by all means connect the BMS and let it do the balancing. If it is rated less than 2A for balancing, do a top balance.
