Light enough to carry in a small daypack. Carries enough charge for my 55 lb Minn lots trolling motor to run for an afternoon of bass fishing. The terminals are not ideal: stainless screws.

I was leery but this battery has delivered for a year or more. No issues. Good price. Make sure your charger is for LITHIUM!

The batteries are as advertised and so far performing seamlessly. On top of that, the customer service is very helpful and responsive. Thank you, Charlie!

Light weight, long battery life

I purchased this 4 pack of Eco-Worthy batteries for my golf cart. You sent 4 and 1 of them is defective, STILL sitting outside waiting for return shipping label from Eco-Worthy, to receive replacement good battery apparently manufacturer doesn't check for quality before shipping. I informed Amazon, then Eco-Worthy of the defective battery as the golf cart requires 48v to operate, I'm only getting 38v, sent to you picture as requested of voltage reading on defective battery, 11.8v this was after individual charging and NOT 13.4 volts as the good batteries. The manufacturer doesn't return phone calls or messages as was told have to contact manufacturer for any problems. Once bought, Amazon washes their hands of any issues or any problems the customer has with the products they sell. Only care about the money. Eco-Worthy so far, is not working with me to pay shipping for return and exchange for quality battery as promised. Will update review if issue ever gets resolved quickly, before I'm forced to take other steps. All I wanted, and paid for, is to get decent batteries for my golf cart to get around my retirement park with my dog, as I'm a Senior and not rich, I chose your product because of good reviews, it's hard to get around sometimes so I bought an older Star golf cart which these batteries are supposed to handle nicely and does when I have ALL GOOD batteries. I hope this can be resolved quickly so I can update my review. I'm tired of looking at, a paid for cart I can't use! All because of careless product shipping of replacement batteries. Let's get done! I'm impatient with such poor customer service, as I am an award winning Retail Manager in customer service myself, and your lack of correspondence makes lack of 100% quality product worse. Let's turn my unhappy face to a happy one so I can issue an updated review to reflect it! I want to finish our business. you are NOT inspiring return business and recommendations. This date on 5/2/2025. Order placed 3/29/2025. And still going in circles with this problem... And NO running golf cart! I had to call the card company toto get you moving on this needless to say, your lack of customer service and correspondence has forced me to take action with the card company. I would prefer you send me a good battery via UPS with order to pick up the defective battery to be shipped back to you. last chance to make things right before proceeding further. I am very unhappy this is not a smooth transaction as it should have been should you check the quality of the product to ship to customers. I strongly urge correspondence immediately, after 5/3/2025, I will consider this a 'you don't care about your customers or your reputation' situation and proceed accordingly. All you need to DO is1. have UPS deliver a GOOD replacement battery and P.U. the defective battery to be returned to you which should have been done to begin with. Our business will be finished should the replacement checked to be good, at which time I will speak to Master Card and return the money that was refunded to me for lack of product delivery to pay for order to be completed to balance money for received order. All will be balanced and good. Business finished. See? These problems happens when companies don't complete orders in full and a timely manner, making sure the products going to customers are 100% good! Thereby a smooth transaction and happy, not distressed customer. Now you know why I received awards for customer service. 100% honest, quality product and secure shipping makes for a reputable company that translates into increased reputation and a profitable business thereby increased income. John Williams. 5/2/2025.Ammendment;Issues with 1st delivery was quickly corrected by Eco Worthy and replacement was quickly sent in new condition.This requires a "well done" with excellent customer service. Will do business again any time with recommendations to others. This is the kind of quality service with product needed in these times.

Light weight perfect for solar lights

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.

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.
