Detailed overview: LiTime 12V 50Ah LiFePO4 Bluetooth battery for trolling motors
The LiTime 12V 50Ah LiFePO4 is a lithium iron phosphate battery with 640Wh of capacity, designed to replace a lead-acid battery on a trolling motor, in an RV, or in an off-grid solar setup. Compared with a lead-acid battery of similar size, it is noticeably lighter, around 11 pounds, and can be discharged nearly all the way down without losing lifespan.
Its LiFePO4 chemistry is rated for more than 4000 cycles at 100% depth of discharge, and up to 15000 cycles at a more moderate discharge, for a service life measured in years rather than seasons. The built-in 50A BMS continuously monitors charge and discharge: protection against overcharge, deep discharge, short circuit, and overheating, with charging automatically cut below 32°F and discharging cut below -4°F, then restored automatically once conditions normalize.
The real draw of this battery is its built-in Bluetooth 5.0: scanning the QR code on the case connects it to the LiTime app with no manual pairing required. You can track voltage, current, and charge level in real time, even across several batteries wired in series or parallel up to a 4S4P setup, for roughly 10 kWh combined. The IP65-rated case resists dust and water splashes, a genuine plus for marine or outdoor use.
With M8 bolt terminals and a compact footprint of about 7.7 x 6.5 x 6.8 inches, it drops in easily in place of a 50 to 70Ah lead-acid battery, whether it is powering a 20 to 70 lb thrust trolling motor, running the electronics in an RV, or storing the output of a small solar kit. It ships with a 5-year manufacturer warranty, in line with what buyers expect from a modern LiFePO4 battery in this price range.

Our tester's review: Julien De Jurquet
We swapped this LiTime 12V 50Ah in for an old lead-acid battery on a small trolling motor setup, and the difference shows immediately: half the weight, and you can genuinely run the 640Wh down without worrying about damaging it, unlike lead-acid. The Bluetooth is well done, pairing via the QR code on the case is instant, and the app clearly shows voltage, current, and charge level, handy for keeping tabs on the battery without pulling out a multimeter. The automatic cold-weather cutoff gave peace of mind on a late-fall outing, though like any LiFePO4 battery, it is best to avoid charging it below freezing. Our one real gripe: the M8 bolt terminals need the right lugs, worth planning for before you install it. For a boat, an RV, or a small solar kit, it clearly beats a lead-acid battery of the same size.
Frequently asked questions: LiTime 12V 50Ah LiFePO4 Bluetooth battery for trolling motors
The LiTime LiFePO4 is roughly half the weight and can be discharged nearly all the way down without losing lifespan, unlike lead-acid, which handles deep discharges poorly. It also lasts far more charge cycles overall.
Yes, that is its main use case: it delivers a continuous 60A discharge for 30 minutes, suited to 20 to 70 lb thrust motors, and it works just as well in an RV or a solar kit.
A QR code on the case links the battery to the LiTime app over Bluetooth 5.0, with no manual pairing needed. It shows voltage, current, and charge level in real time, even across several batteries wired in series or parallel.
The BMS automatically cuts off charging below 32°F and discharging below -4°F to protect the cells, and restores both automatically once temperatures return to normal. As with any LiFePO4 battery, avoid charging it in freezing conditions.
Yes, up to a 4S4P setup, four in series and four in parallel, building a system that stores roughly 10 kWh, handy for expanding a solar installation or an off-grid system over time.
