Hard Water

A Flasher That Lasts the Whole Trip

Sealed lead-acid loses capacity fast in the cold and takes a real toll on the sled. A compact lithium pack weighs a fraction as much, holds voltage as the temperature drops, and still has usable power when you are drilling the last hole of the day.

Frequently Asked Questions

Choosing the Right Battery

Can I charge a lithium battery in freezing temperatures?

No — charging LiFePO4 below freezing can permanently damage the cells. Discharging in the cold is fine; bring the battery indoors to warm up before you charge it.

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.

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.
