Appendix B – Connection to Multiple Batteries

Identical batteries can be connected “+＂to“+＂and“–＂to“–＂in a parallel for larger capacities while maintaining the supply voltage of a single battery (See Figure 7). Do not mix batteries from different manufacturers or different amp-hour ratings in parallel as battery life would be shortened.

NOTE: If different batteries or more than two batteries are needed, set up separate battery banks and use them separately. Battery selectors are available from marine and RV dealers to select between battery banks. Switch to either bank or disconnect all (See Figure 8.)
