Features
- [For Trolling Motors] The ECO-WORTHY 12V 50Ah LiFePO4 battery is specifically designed for 30lb-50lb trolling motors, making it ideal for brands like Minn Kota, Newport Vessel, and PEXMOR. With 640Wh of energy, it provides reliable and long-lasting power. Compared to traditional lead-acid batteries, they offer a greater depth of discharge (DOD), allowing for continuous operation of an 80W load for 8 hours.
- [Lightweight Design] The 50Ah lithium battery features a lightweight design, weighing only 12.65 pounds, significantly lighter than lead-acid batteries. It is only 42% the weight of a 12V 50Ah lead-acid battery (around 30 pounds). This makes it easy to use outdoors and allows it to be placed in many locations where lead-acid batteries cannot be used. It is globally compatible with battery boxes for all vehicles on the market, saving installation space.

Higher than lead-acid batteries (generally only 300-400 cycles can be charged). ECO-WORTHY batteries can maintain 80% capacity after 3000 cycles, ensuring long-term reliability and cost-effectiveness.
- [Smart 50A BMS] Built-in 50A BMS(Battery Management System) Securely protects the cells from overcharge, over-discharge, high temperature, short-circuit, and discharge overcurrent. And keep the balance between battery cells.which supports 50A max. continuous charge/discharge current, 640W max. energy.
- [3 Ways to Charge] ECO-WORTHY 12V 50Ah LiFePO4 Battery Supports three charging methods: Charger, Solar Panel with Charge Controller, and Generator. A 10A charger only takes 5 hours to charge fully, with a Charging efficiency of over 90%, while lead-acid batteries usually charge between 70-85%.
- Our batteries undergo rigorous testing and meet industry standards, including certifications like UN38.3, UL 2271, and CE, ensuring top safety, quality, and performance.

Battery works perfectly with trolling motor. Light, compact, with plenty of juice. When battery arrived, it came with nothing else--no screws, no terminals. Contacted company via email. First reply: Take a photo of the battery as it arrived once out of the box, which I did of and emailed. Second reply: Factory forgot to supply everything. Company's solution was for me to go buy the parts from a hardware store and send the company the receipts for reimbursement. Not exactly the reply I wanted. Almost decided to send the battery back, but instead bought some M6 screws and mounting terminals. Not worth the trouble to seek reimbursement. First ever customer service response for me to fix the problem myself for their mistake.

I originally left a 1 star review because my first battery stopped holding a full charge, but Eco-Worthy's customer service reached out to me and got me a replacement battery. Surprisingly excellent customer service. I will update this review again if I have issues with the replacement batter, but so far - so good.

I was impressed on receipt of this product. It was very well packed and promptly shipped and the first thought was how light it is. I installed it in my 16' boat to replace a lead acid battery that powered my trolling motor and running lights. Handling the two made me wish all my batteries were this light and easy to handle. I bought a new charger to go with it and learned from it that the battery arrived with about a 40% charge. It quickly came up to 80% with no sign of heating up. I haven't used it in the field yet to test how long a day it can put in. As it is, I turn on the trolling motor every few days and certainly haven't noticed any change in power from those little tests. To check that after a couple of weeks of these little checks, I just now put the charger on it to to see what the current level of charge is. It is still at the 80% from the original charge. The instructions say that if the battery is stored for a significant length of time, it should be kept at 40 to 80% and kept from freezing. As we are in southern Missouri and the boat is stored in the garage attached to the house where the temp very rarely drops below 55 even in our worst weather, I expect that I'd be okay leaving it untouched for at least the next couple of months. At this point I would highly recommend this battery. Given that it is projected to last 10 years, it seems to me superior in all ways to lead acid. The only thing that would change that opinion at this point is if it fails to provide sufficient power for a full day's fishing and, given some good weather, I'll test that out before too long and report back if it doesn't live up to expectations As a test of performance I let my trolling motor run on its middle speed for two hours then checked how much that depleted my charge. It used less than 20% of the charge. To fully recharge the battery took just under 1 hour. I would rate that performance excellent. I'm fully pleased with this result and so will highly recommend this product.

Excellent cost benefit replacing my 35A SLA battery with this one that is much lighter and more capacity due to lower discharge ability. Using this to power ham and GMRS radios in the field along with running small appliances and charging USB devices. Cost performance is superior to SLA as it is higher capacity, longer stated life and carrying ease all at a lower expected life cycle cost over SLA. Recently bought so not sure about "longivity." Remember to charge at higher than freezing temps.

Runs my Go Box amateur radio station, 2 radios HF and VHF/UHF auto tuner an Ontario’s laptop for 22 hours continuous duty. Doing hourly check in activity then shutting this would probably provide operational capability for at least 7-10 days.
