ECO-WORTHY 12V 200AH (2Pack 100AH) Mini Size LiFePO4 Lithium Iron Phosphate Battery with BMS, Up to 15000 Cycles, For RV, Trailer, Trolling Motor, Camping, Solar Off-Grid System, Group 24 Batteries

I bought the pair a couple of weeks ago and tested them over the past few days. One battery charged fine and discharged using a 20amp load. Recharged using a smart LiFePo4 charger at 15amps setting and it came up to 100% of capacity rating of 100amps. The second battery was charged and likewise discharged into a 20amp load. I recharged this one as well, but it only came up to 98% of capacity, not the full rated power of 100amps, just 98amps. I ran the test again, same problem but this time only came up to 95%. I contacted the seller via Amazon who replied within 24 hours. They verified my testing and honored a request for a replacement battery. The battery arrived and tests great. Seller is very easy to work with and really wants to ensure customers are pleased with their purchase. I could not have been more pleased with the result. Thanks!

Bought these to replace my single RV battery that came with my camper. These are way lighter and store more energy and work great for keeping my essentials going while im off grid. My 2 solar panels have no problem keeping these charges up for night time to keep the 12 volt refrigerator going all night. No, they wont run my RVs AC unit but I have a gas powered generator when I need to do that, bit they are the most bang for the buck. Similar batteries are more expensive so I am pretty happy with these so far.

Installed in a Ryobi ZT480 mower to replace poor choice of OEM, AGM batteries that were a failure by Ryobi, customers not compensated. These were cheaper than the OEM replacement even with the needed charge controller. Battery powers mower better and much longer than Ryobi OEM. Recommend for this type of use. I am expecting longer performance in years as well. Mower is also 200 pounds lighter with these batteries.

I purchased a set of three of these batteries for my 1987 EZGO Marathon. These fit the existing battery tray and replaces six lead acid batteries with three much lighter batteries. I also installed the battery balancer by the same manufacturer which others have said is required. A step down transformer 36v to 12v is also needed. Cart runs fine, no increase in speed but big increase in range.

Installed in a 2004 club car ds as a conversion from lead acid. Worked great and easy to install. Been in the cart for awhile now. Had one little hick up where one battery had an extra draw for the 12v lighting. Seller was very helpful in figuring outwhat happened and was ready to do a warranty replacement. Was able to get the battery to recover with the sellers help. I just installed an eco-worthy battery balancer to prevent that from happening again. I would highly suggest getting a battery balancer when purchasing multiple batteries. Now I can drive about 3 times the distance I could on lead acid. I get about 4 miles per 10% of battery power.

I bought two sets of these batteries and they have been great. I just got done talking with their customer service and they helped me troubleshoot the issue which ended up not being a battery issue. Would definitely buy again.

I bought two batteries. One works great and one does not work at all! They keep saying do not return bad battery and that they will send a replacement. It has been OVER two weeks now and still no replacement! I am not impressed at all! UPDATE: I have now received a replacement battery and it's working great! Thank you Ecoworthy!

I don’t usually write reviews on products but I feel it’s necessary to do so, regarding this company and their customer service! I purchased this 4 battery set, installation was fairly easy but once the batteries were installed I discovered one battery had a defective BMS unit. I contacted this company’s customer service and without hesitation they offered to replace the defective battery. I advise anyone searching for Lithium batteries, to buy thru their company. I’m excited to receive the new battery and spend countless days on the golf course, reduced charging time, with less charging! Thank you
