Marine Batteries Shipped to Flathead Lake, MT
Flathead Lake, in northwest Montana, is the largest natural freshwater lake by surface area west of the Mississippi in the lower 48, with very clear, cold water.
We don’t have a shop in Flathead Lake. Marine Battery Source is an online store, and we ship to Flathead Lake and the rest of Montana. Lithium batteries over $150 ship free by curbside truck freight to the lower 48. Chargers and accessories ship free when your cart reaches $150. Lead-acid and AGM batteries ship free by curbside truck freight too.
Fishing near Flathead Lake
Lake trout, yellow perch and whitefish are fished. Pontoons, sailboats and fishing boats are common.
Flathead Lake waterways
Polson sits at the south end, and Bigfork is on Bigfork Bay at the north end. The Flathead River flows in from the north, and Wild Horse Island State Park is in the lake.
Boats are stored for winter. The south half of the lake lies within the Flathead Indian Reservation, and fishing there requires a permit from the Confederated Salish and Kootenai Tribes. Montana requires boats to be inspected for aquatic invasive species before launching in the Flathead Basin. Cherry orchards line the east shore, and the lake hosts fishing events for lake trout. Afternoon winds can build big waves on the open lake, so batteries need firm mounts. The season is short, and mornings stay cool even in summer, so standard lithium batteries should be charged above freezing in spring and fall.
Batteries that fit Flathead Lake boats
Pontoon boats
A pontoon spends more time idling and anchored than running, so the engine has little chance to recharge the battery. Plugging in a charger after every trip, or switching to lithium with its faster charge acceptance, keeps a pontoon ready for the next evening cruise around Polson Bay.
Sailboats
Sailboats and cruisers in Flathead Lake rely on a house bank for lights, refrigeration, instruments and an autopilot, plus a starting battery for the auxiliary engine. A bank of 6V golf-cart batteries wired in series is a traditional choice; lithium banks like the EPOCH 12V 300Ah or Battle Born 100Ah give more usable capacity and recharge faster from solar or the engine.
Walleye and multi-species boats
Multi-species boats on Flathead Lake usually run a bow-mount trolling motor, a kicker motor and a big main engine. Lithium trolling batteries save weight and provide steady power.
Seasons and storage
Cold mornings matter for lithium charging.
High-altitude lakes can be cold even in summer. Lithium batteries with internal heating are a good choice for early season use.
Mountain lakes have short summers and cold winters. Most boats are stored in winter. Charge batteries before storage, and charge lithium only above freezing unless it has internal heating.

Frequently asked questions
Do I need a heated lithium battery for Flathead Lake?
Only if you plan to charge in freezing weather. Standard lithium batteries should not be charged below 32°F. Batteries with internal heating, like several EPOCH models and the Dakota Lithium DL+ 135Ah, warm themselves before charging. For normal spring-to-fall use with winter storage, a standard lithium battery is fine.
Can you ship to my marina?
We can ship to most addresses, but marinas with restricted access or no way to receive freight may cost extra or need special arrangements. A home or business address is usually easiest. Contact us before you order if you want to ship to a marina.
Who schedules the delivery?
The freight carrier calls the delivery phone number you enter at checkout to set up a delivery window. Someone needs to be there to inspect the shipment and sign.
Do you have a store or installer in Flathead Lake?
No. We ship to Flathead Lake from our store. Professional installation is a flat $99 per battery ($249 for a 24V or 36V lithium bank) anywhere from Venice to Gainesville, with no travel charge.
