The lithium battery built for serious ice fishing electronics.
If you're running LiveScope, MEGA Live, ActiveTarget, ECHOMAP, or any modern forward-facing sonar setup, you've already learned that lead-acid batteries can't keep up. Voltage sags, screens dim, picture quality drops, and you end the day with half your fish-finder runtime gone. The Amped Outdoors 52Ah is what serious ice anglers and tournament-style boat anglers run instead.
This is the larger of the two Amped Outdoors batteries we carry. Pick the 52Ah if you fish all-day sessions, run LiveScope continuously, or want a single battery that powers a full day without swapping. If you fish shorter sessions or just want a lighter pack, the 32Ah version makes sense.
Why lithium beats lead-acid for fish-finders:
-
Steady voltage all day. Lithium holds its voltage at 14.8V from full to nearly empty. Lead-acid sags as it drains, and your fish-finder display goes with it.
-
Half the weight. 7 lb 1 oz versus 25-30 lb for an equivalent lead-acid. Easier to carry on the ice, easier to fit in a tournament pack.
-
800 to 1,000 charge cycles. Three to four times the life of a typical lead-acid. Runs you longer per dollar over the life of the battery.
-
Full power in cold weather. Operating temperature down to -20°F. Lead-acid loses 30-40% of its rated capacity below freezing.
Built for these fish-finders and electronics:
- Garmin LiveScope and LiveScope Plus systems
- Humminbird MEGA Live
- Lowrance ActiveTarget
- Garmin ECHOMAP Ultra series
- Garmin GPSMAP series
- Humminbird Helix series
- Any 12V or 14V fishing electronics rated up to 17V input
Bluetooth monitoring:
The 52Ah includes built-in Bluetooth monitoring. Pair it with the Amped Outdoors app on your phone to see real-time voltage, remaining capacity, charge cycles, and time-to-empty estimates. Useful for tournament anglers who can't afford to run out mid-day, and for anyone who wants to know what their battery is actually doing.
What's in the box:
- 52Ah Lithium Battery (14.8V NMC) with built-in Bluetooth monitoring
