ECO-WORTHY 12V 50Ah LiFePO4 Lithium Battery with XT60 Interface, Bluetooth 5.0, Low Temp Protection, Connects to Power Inverter for Camping, Road Trips,Trolling Motors

Fully tested it by running electric outboard motor in a barrel of water. App works great. Capacity as advertised. The 12v plug is a nice feature that I didn't think I cared about but have used it.

This is an amazing battery. I absolutely love it for running the electronics on my boat. I will buy many, many more eco worthy batteries in the future. The bluetooth feature helps you manage your battery and get the most out of it and not charge unnecessarily. This battery holds a charge and does not bleed off.Like my lead acid.

Bought qty 2 of the two pack of these batteries (4 total) to replace the OEM lead acid batteries in my Ryobi RM300e 30" electric riding mower which failed after 2 seasons. Electrically they are spec'd perfectly for this mower and weigh maybe half what the original lead acid battery pack weighs. However there are a few things to note: these batteries are slightly larger in all 3 dimensions (length, width, height) than the stock lead acid batteries, just enough that the original hold down bolt will not work. NOTE: If you're mechanically inclined, continue reading. If not, seek assistance from this point! Buy a 350mm M8 x 1.25 threaded rod and nuts/lock washers for this. Plus you will need to trim that threaded rod down to make it fit. In addition, this mower has 2 metal brackets in the center that need removed or beaten out of the way since they are JUST too far apart for these batteries to fit. But if they are not there or moved out of the way, these batteries will fit. If you get past this point, the next obstacle is the charging port. The stock Ryobi lead acid charger will simply charge forever and overheat. get a smart charger with a delta plug shape which costs about the same as one of these batteries. Then break the two plastic tabs in the stock ryobi charging port on the mower between the 3 circular terminals. They aren't connected to anything and just break off. Get to this point and these batteries in series are good for at least an acre connected in series to produce 48V and over an hour of operation. Recommendation: look up replacement ammeters as the stock Ryobi battery meter only shows battery voltage which will be constant on these batteries until they're dead due to the chemistry. A coulomb meter (showing amp hours remaining) will show actual remaining battery life with these.

My initial review was for 5 stars. The batteries were for replacement of the LA in my Ryobi rm300m. I purchased the eco-worthy charger at the same time. They worked great for about a month after full charge and install in the spring. Seemed to work for about 2 months. Then the mower would show charged, but would die immediately after starting mower blades. I was diagnosed and went through cancer treatments right after this started. I just became able to address the issue again, which put me a little over the 12 month fully warranty. I was hoping that Eco-worthy would do the right thing and either replace the 3 defective batteries that will not hold a charge, or refund my money in full so that I may purchase replacements. Currently they are trying to only give me less than 100%, which will not cover replacements, and I am at 13 months from purchase date, not received date. Edit 2: they agree to refund the 3 defective batteries and then told me these batteries are not compatible with the ryobi rm300e mower. I still await the refund. I also have a single battery that I cannot use in a year other item i own. Now I don't know where to go with this!

Purchased to provide dedicated power for a Garmin livescope, on my boat. Use one to power 2 10” graphs & the livescope. So far so good. Going to try the other two, to power a 24v trolling motor on my tin boat.

Still going strong after a busy mowing season inside a Ryobi riding electrical mower. A direct replacement for the old lead acid batteries.

the XT60 interface is wonderful, much faster than screw on terminals. The app not only shows how much battery you have left and the voltage but also how many amps and watts your equipment is pulling. It also reads 13.6 fully charged which is great. Fraction of the price of the name brand batteries, the cells are probably from the same factories anyway.

Excelente producto. Muy intuitivo. El Bluetooth funciona perfectamente. Excelente para tareas al aire libre.
