Not sure which battery you actually need? You’re not the only one.
We get this question all the time—especially with forward-facing sonar setups.
Here’s the quick breakdown:
20Ah → lighter setups, shorter trips
32Ah → most popular, all-day fishing
52Ah → bigger screens, longer days
Most people underestimate what they need… and end up upgrading later.
If you’re unsure, going one size up usually saves you the headache.
