The sealed lead acid used in batteries is an unstable substance, and the absorbed glass mat contains the acid effectively (so it can’t spill). The absorbed glass mat also stabilizes the plates inside the battery, making it much more difficult for them to shift. If you have a longer, heavier boat, you’re obviously going to need more lbs of thrust out of your trolling motor. This might mean a decision to use a 24 or 36-volt trolling motor.
