Best 12V 100Ah Group 24 LiFePO4 battery with Bluetooth for a trolling motor under $300 (2026)
Updated 2026-11-08
Short answer. Buy 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), the best Group 24 LiFePO4 battery with Bluetooth for a trolling motor under $300: $259.99 on 2026-11-03 (list $359.99; code VIPD2026 took 5% off in the cart) for 1,280 Wh with a 150 A BMS, a UL 1973 listing, a low-temperature charge cutoff and an IP65 case. LiTime's Group 24 Bluetooth was $365.99 and Redodo's $289.99 on their own stores the same day, both with 100 A BMSs.
What to know: the same LiTime and Redodo packs turn up cheaper at resellers ($229.99 at Renewable Outdoors, $219.99 at Walmart in search results), so compare on the day; what the Vatrer adds at any price is the 150 A BMS against 100 A, which matters when a trolling motor and a fish finder pull from one battery, and the UL 1973 listing no rival in this table claims. The Bluetooth app shows state of charge, voltage, current and temperature; charging stops below 32 °F. Weight is about 11 kg (24 lb) shipping, in the standard Group 24 footprint. Vatrer's US warranty table gives 12 V 100–600 Ah batteries 5 years after registration and activation, but its Japanese-market page says powered-equipment use such as trolling motors carries 1 year, so ask Vatrer before counting on 5 for a boat. Dakota Lithium's Group 24 ($699–799) is the premium pick with an 11-year warranty; this is not a starter battery.

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 (Dakota Lithium, LiTime, Redodo, Renogy) are included so the comparison is complete; their figures and prices were read from the makers' own US pages on 2026-11-03 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.
Why the BMS rating matters on a boat
A 12 V trolling motor on high draws 40–60 A, a 24 V setup on two batteries less per battery; add a fish finder, livewell pump and lights and a 100 A BMS is still within limits but closer to them, and a BMS that trips under a surge shuts the whole battery off until it resets. Vatrer's 150 A rating is the headroom. None of the packs here is a starter battery, so an outboard's starter stays on its own lead-acid or dual-purpose battery.
Price on the day, and where
On 2026-11-03 the makers' own stores had Vatrer at $259.99 (5% off with VIPD2026, which passed in the cart), Redodo at $289.99 and LiTime at $365.99 for the Bluetooth Group 24; search results showed the LiTime at $229.99 at Renewable Outdoors and the Redodo at $219.99 at Walmart. Reseller prices move faster than the makers', so the honest statement is that Vatrer is the cheapest on the brand stores and within $40 of the cheapest reseller listing, with the stronger BMS.
The warranty question
Vatrer's warranty table (July 2026) lists 5 years for 12 V 100–600 Ah batteries, after registering and activating the warranty before first use. Its Japanese-language page for the low-temp Group 24 says powered equipment such as trolling motors, golf carts and kayaks gets 1 year; the US page does not say that. Until Vatrer confirms in writing, plan on 1 year for a trolling motor and treat 5 as the RV term. LiTime states 5 years and Dakota 11.
What we could not verify
UL listings for the LiTime and Redodo packs, Redodo's warranty term, Renogy's and Dakota's current prices and BMS ratings, any capacity test or teardown of the Vatrer Group 24 (Wired2Fish ran it on a kayak for three weeks without publishing a capacity figure), and the Vatrer's net weight.
