Comes to a technique about pre-charge versus not pre charge. I think the pre-charge is safer if done with the BMS rather than just leaving the cells on a power supply.
To me with the BMS, I can check the cell status frequently and see if they jump up. I don’t know individual cell status in parallel. As far as doing that and not being as safe in parallel, if the parallel voltage is set to 3.6, I don’t see how it’s dangerous.
The biggest reason I like the pre-charge first is my Dr. Meter 10 amp 30 volt power supply the voltage has wandered twice To too high. I can check frequently the status if the cells are only in parallel for three Hours, but IMO I can’t check very well two weeks straight Without the pre-charge. That may just be the Dr. Mater power supply, but I see that power supply is used more than any other power supply.
