I design it to make 3s5p battery pack from scratch for my 3d printer backup power.
I use 3s 25A li-ion bms board to protect the battery pack and connect its terminal directly to 3d printer's 12V power supply (after adjusting the voltage to 12.6V, as fully charged single li-ion would reach 4.2V, so 4.2*3=12.6).
The batteries itself was cheap used 18650 battery with 5A rating each.
It did save me a lot as I'm currently live in house with small rated circuit breaker which frequently cut off.
