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.

    • Recently purchased so I have no knowledge about longevity.
Size: 12V 50Ah
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. ... show more

    • Reliable power source
Size: 12V 50Ah
This battery has operated flawlessly through 34 POTA activations and 5000 QSOs. It baffles me why so many hams willingly pay 300% more for the "name brand". -AI4BJ

    • Work well and light weight
My husband uses these on his boat. They work well and are not as heavy as regular batteries. Easier to lift in to the boat.

    • Works Great for EZ GO Golf Cart
I was a little apprehensive at first thinking these smaller in size and much lighter batteries would power my 36 volt golf cart. They are much better then the lead acid I replaced them with in every way. They Will run the cart for over 2 days using it quit a bit, and going faster than before. You will need to get a Lithium Battery charger. The price was good and the performance is better than expected. ... show more

    • Dead...I think.
Size: 12V 50Ah
Ordered this item and it arrived today. DEAD! Won't charge, won't deliver 12 V to my electronics. Test with multimeter shows <= 11V (fluctuates). Contacted customer service but waiting for response.

    • Battery won't take a charge after 2 seasons-manufacturer honored warranty
Size: 12V 50Ah
Purchased 2 12.8 V 50 AH batteries for a trolling motor 2 years ago. One is fine and in fact holds a charge all 8 months of our off season. The other inexplicably is dead and won't take a charge. It also mysteriously weighs 4 lbs. LESS than the good battery. WTF??? I've cleaned the terminals, checked the charger, successfully charged the good battery with the same charger- no luck with the other battery. Disappointed to say the least. Update- shortly after posting the initial review, I was contacted by Eco worthy and offered a full refund or a deep discount on a larger 100 AH battery. They seemed to think that the 65 lb. thrust motor I was using the battery with may have been too much draw for a 50 AH. I gratefully upgraded to the 100 AH battery and am hoping this solves things. Excellent customer support in this instance. I have read, however, that LiFePO4 batteries cannot be left without maintenance charging for months at a time, as is necessary in my situation. Apparently they can self discharge to a point that they cannot take a charge ever again...time will tell, but the company has stood behind their warranty. ... show more

    • Price and dependability
Size: 12V 50Ah
Works great with my IC-7300, so far have I used it for 6 hours on one charge. Curious to see how long it would actually keep working.

    • Great battery for the price
Size: 12V 50Ah
Using this as part of a battery box for remote/mobile power. Incredibly light weight. Using as part of a ham radio setup and maintains steady power throughout the operation. Done some burn-in testing and so far it's meeting expectations. I thank them for the supplied tool for inserting the terminal screws. Very handy! ... show more
