I have some 12 V lead-gel batteries for my existing devices. Now I need 24 V power supply for my new device. I should
1: use two 12V batteries connected in series to have 24V or
2: buy 24V battery with a charger or
3. use one 12v batteries and buy a dc-dc converter to step voltage up to 24V
If I use a battery, do I need protection/regulation circuit?
Many thanks in advance.
p.s. sorry, my linux pc does not support Thai font :(
