Best trolling motor with battery

Updated 2026-11-06

Short answer. The best trolling motor with battery for most small boats is a 12 V transom motor paired with the Redodo 12V 100Ah Group 24 Bluetooth ($259.99; buy: https://dealectric.com/go/redodo-12v-100ah-group-24-bluetooth-low-temp, code AW10 saves $25.99, pre-applied by the link): 1,280 Wh at 21.8 lb, good for about 2 hours of full throttle or 4 to 5 hours at half speed on a 55 lb motor, with an app that shows the real charge left. Trolling motors ship without a battery: Minn Kota, Newport and MotorGuide transom motors all need a separate 12 V deep-cycle battery and a matching charger. If you want the battery built into the motor itself, the ePropulsion kLite 750 (378 Wh inside the housing, 14.3 lb, 2 hours 48 minutes at 4 mph) is the honest winner for kayaks and the Spirit 1.0 Plus (1,276 Wh) for dinghies; neither is sold by a store we work with.

The run-time math is simple. A 55 lb motor such as the Minn Kota Endura C2 55 draws up to 50 A at full throttle, so a 100 Ah lithium pack lasts about 2 hours flat out and 4 to 5 hours at the 20 to 25 A of half speed. A 30 lb motor draws up to 30 A, so the same pack runs over 3 hours at full. A 50 Ah pack halves those figures. Lithium gives its full rated capacity; a lead-acid battery with the same label gives about half before the voltage sags, which is why owners of 35 Ah lead-acid "kayak" batteries report a 55 lb motor dying in about 30 minutes.

Three checks before buying any lithium pack for a trolling motor: the BMS continuous rating must exceed the motor's maximum draw (100 A on the pick, against 50 A for a 55 lb motor), you need a 14.6 V LiFePO4 charger ($82.99; buy: https://dealectric.com/go/redodo-14-6v-20a-lifepo4-charger refills it in about 5 hours), and the battery refuses to charge below 32°F, so bring it indoors in winter. If your motor pulls more, or you run a fish finder off the same battery, the Vatrer 12V 100Ah Group 24 ($259.99; buy: https://dealectric.com/go/vatrer-12v-100ah-group-24-bluetooth-150a, code VIPD2026 saves $12.99, pre-applied by the link) has a 150 A BMS at a similar price.

Rows marked with a code and buy link are products Dealectric lists: the price was verified on the brand's own US store on 2026-11-07 and the code is tested daily in that brand's cart; the date shown is its last pass (last check 2026-11-13). The other rows (Newport, ePropulsion) are included so the comparison is complete; their figures and prices were read from the makers' own US pages on 2026-11-06 and are not re-checked daily. The buy links are affiliate links: they open the brand's official US store at no cost to the shopper, and the commission pays for the testing; see the disclosure.

What owners complain about

We read Newport Vessels' battery troubleshooting guide, the In-Depth Outdoors and iBoats lithium threads, Outdoor Life's NK300 test, Panbo's Spirit 1.0 Plus review and Practical Sailor's electric dinghy survey. The pain points, by how often they came up:

• Cold-weather charge lockout (6 posters). Every LiFePO4 pack blocks charging near 32°F. One owner's two 100 Ah packs refused to charge at about 30°F until he added a heating pad. Discharge still works down to about 4°F, so the fix is charging indoors.
• Battery failures (5 reports). A 24 V pack that would not take a charge after one trip, two packs with water in the BMS replaced over four years, a Torqeedo battery dead inside a year. Buy from a brand with a written multi-year warranty and keep the receipt.
• Less run time than expected (4). Undersized batteries make the motor slow at high speed. The Outdoor Life tester ran a 36 V 30 Ah pack flat fighting current and needed 50 Ah for a full day. Size by your motor's amp draw, not by marketing hours.
• Weight on a kayak (3). Motor, mount and battery added about 40 lb to a Vibe Shearwater 125, and lead-acid packs sit the hull lower. An 11.3 lb 50 Ah or 21.8 lb 100 Ah lithium pack is the fix.
• Replacing a built-in battery (3). The Spirit 1.0 Plus battery is $1,349 on its own, a Torqeedo owner paid $1,000 for a replacement, and a Bixpy owner budgeted about $500 after three seasons. A standalone 12 V pack costs a fraction of that and fits any motor.
• Not knowing the charge left (2). Motor-mounted meters are calibrated for lead-acid and misread lithium, and lithium cuts out abruptly at empty. A Bluetooth readout fixes both.

Which one by need

• Jon boat, canoe or kayak with a 30 to 55 lb 12 V motor: the Redodo 12V 100Ah Group 24 Bluetooth. 1,280 Wh, 21.8 lb, 100 A BMS, 5-year warranty. Add the 14.6 V 20 A charger if you don't own a LiFePO4 charger.
• Kayak angler who paddles most of the day and motors home: the Redodo 12V 50Ah Bluetooth. 11.3 lb saves 10 lb on the stern; expect 2 to 3 hours at half speed on a 55 lb motor and more with a 30 lb motor.
• No wiring at all on a kayak: the ePropulsion kLite 750. Battery inside the housing, 14.3 lb, IP67, 2-year warranty. Its 378 Wh gives 48 minutes at full power, so it suits anglers who troll at 2 to 4 mph, not sprinters.
• Dinghy or small jon boat, battery in the motor: the ePropulsion Spirit 1.0 Plus. 1,276 Wh floating battery, 1 h 15 min at 1 kW, 8.5-hour standard charge. Panbo's owner-reviewer found it quiet and $700 cheaper than the Torqeedo Travel 1103C, with a dim display and no GPS as the trade-offs.
• Motor and battery in one order: the Newport NK180 HD Bundle. 600 W motor, 24 V 50 Ah lithium pack and charger for $1,924.97, versus $1,299.99 for the motor alone.
• 24 V or 36 V bow-mount on a bass boat: Redodo's 24V 100Ah Group 31 Bluetooth (2,560 Wh, $569.99) or 36V 50Ah (1,920 Wh, 32.8 lb, $359.99), both seen on 2026-11-06. One pack replaces two or three lead-acid batteries.

Not recommended

• 35 Ah sealed lead-acid "kayak" batteries. Newport's own guide says a 55 lb motor runs about 30 minutes at full speed on one, and the plates sulfate if the battery sits discharged.
• Any lithium pack with a BMS rated below your motor's max draw. A 55 lb motor pulls 50 A; a 40 lb motor pulls about 42 A. A 30 A or 50 A BMS trips at full throttle.
• Bixpy K-1 Outboard Kit for an all-day angler. $1,399 buys the same 378 Wh as the kLite 750 but the mounting adapter is sold separately, and a Hobie forum owner's main gripes were fixed speed steps and no larger battery option.
• Torqeedo Travel for buyers who can't absorb a battery replacement. Practical Sailor writes that it has heard of too many Torqeedo failures to recommend them, and a reader paid $1,000 for a replacement pack. ePropulsion's record over six years was cleaner in the same survey.
