Thus, the 12 volt battery is required, size 200 ampere, 1 x 12 volts, but the ball 200 ampere, with big easy to use size 12 volt batteries, so choose a 100 Ampere, the number 2 is equal to 200 ampere,
So, take the battery 12 volt 200 ampere number one ball, but the battery 12 volt 200 amp larger inconvenient to use. The selection of 12-volt batteries 100 amperes to 200 amperes of two equal balls.
Therefore, must be used, the size of the battery 12 volt ampere of 200 1. But, the size of the battery 12 volt ampere 200 is large, inconvenient to use. So we choose to use, the size of the battery 12 volt ampere of 100 2. As 200 ampere.
