ECO-WORTHY 12V 50Ah Trolling Motor LiFePO4 Lithium Battery with BMS, 3000~15000 Times in Deep Cycle, for 30~50lb Trolling Motor, Travel Trailer, RV, Marine, Solar, Power Wheel Chair

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 expectationsAs 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.

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

This battery is light for it's size and capacity! I use it on my traveling motor. Definitely recommend!

Light weight perfect for solar lights

I have had this battery for close to 2 years and it has performed flawlessly on both my trolling motor in the summer, and on my diesel heater in the winter. I would highly recommend this company and product.

This is an excellent battery , but in my opinion , we gotta raise the minimum size for 2025.If you're gonna spend the money Just get something bigger.You're probably gonna need it.And eco worthy is always offering discounts and promotions , so always contact them for the best offer.

Use this on my kayak. Can use it for 3 or 4 days before recharge needed

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.
