In larger battery banks, where you have multiple series – parallel strings of batteries, you run the risk of some batteries getting more “used” than others, and this degrades your pack performance. A simple way to reduce this effect is to cross-tie your batteries. This is a rarely used but important method of getting extreme life out of your expensive batteries. Here is an example:
The dotted lines are the cross tie cables. It’s also important to make sure your cables are heavy enough, that you are not losing power as heat through resistance. If you have caps on your batteries, not maintenance free, check the water levels once a month and top them off during charging. Do not overflow. Next we will discuss pulse desulfators as another method of extending the life of your batteries. Stay tuned.
