Fishing Batteries
Light, compact lithium batteries for shelters, kayaks, portable graphs and everything you carry in rather than trailer.
Portable Fishing Power
U1 and compact LiFePO4 batteries sized to be carried.
Every Pound Matters When You Walk
Shelter, auger, rods, bucket — the battery is the one item you can genuinely make lighter without giving anything up. A compact LiFePO4 pack runs a portable graph all day at a fraction of the weight of the sealed lead-acid brick it replaces.

Frequently Asked Questions
Choosing the Right Battery
What does LiFePO4 mean, and why does Pro-Guide use it?
LiFePO4 — lithium iron phosphate — is the most thermally stable lithium chemistry in common use. Compared with lead-acid it holds voltage under load far longer, weighs a fraction as much for the same usable capacity, and needs no watering or terminal maintenance.
How many amp hours do I actually need?
Add up the amp draw of everything the battery has to run, multiply by the hours you want between charges, and leave some headroom. If you would rather not do the math, our team will size it with you over the phone.
Will a lithium battery work in the cold?
LiFePO4 discharges well in the cold, but charging a lithium battery below freezing can damage the cells. Bring it inside to charge, and check the product page for the rated operating range.
Charging & Maintenance
Can I keep using my existing lead-acid charger?
A lead-acid charger can undercharge a lithium pack and shorten its life. Use a lithium-compatible charger — everything in our Lithium-Compatible collection is profiled for LiFePO4.
What maintenance do these batteries need?
None of the routine watering or terminal cleaning that flooded lead-acid requires. The built-in BMS manages charge and discharge protection automatically.
Warranty & Support
What warranty comes with these batteries?
Terms vary by product line — the term for each battery is listed on its product page, and the full details are on our Warranty Information page. Register your battery online after purchase to activate coverage.
What if I am still not sure which one to buy?
Call our US-based battery team on 1-800-827-3232 before you order. Tell us the machine, the tray you are working with and how long you need to run between charges, and we will point you at the right part number, or message us.
