About BMS for lead acid. : r/batteries
Lead acid must be (carefully) overcharged regularly to equalize and prevent sulfation.. Your link seems to be a solution in search of a problem, and having failed to find one they invented some. The "then some batteries get overcharged while some remain undercharged" is possible if you use different sized batteries (36Ah in series with 40Ah) or with ''nameplate'' same Ah-sized
How can I make a battery management system? : r/esp32
In this case I would use a sealed lead acid battery. A 7Ah 12V battery from a security system will run those LEDs for hours. To charge it, use a 14-15V power supply rated at 1-2 amps in series with a 4-5ohm power resistor rated at 10-20W. Check charge current with a multimeter to dial in the exact resistance for 0.1C charge rate (about 700ma).
