If there are two different types of batteries, is it possible to connect the plus plus and minus minus of the battery to make a single battery and charge it?
Overall battery will be like, voltage 24, ampere 50, power = 24 * 50 =1200 watt , you will be at loss because single 12 volt ,130 amp battery can provide 12* 130=1560 watt power . Other battery 12* 50= 600 watt. Add them in parallel for max advantage in this case voltage will be 12 and amp will add to give 12 *(130+50)= 2160 watt hoping u get ur answer.
