If you are going to dry camp more than a day or two every once in awhile, then you need a battery monitor that tells with precision the state of the charge remaining in the batteries. A battery monitor is a digital meter/computer that reports voltage, amp flow into and out of the batteries, amp hours remaining and operating time left. Without a monitor, you are shooting in the dark about not only the remaining charge, but how many amps different devices use. This is vital information to be able to dry camp for several days without damaging the batteries.
Here are two manufacturers:
Xantrex LinkLite and LinkPro
TriMetric
