ECO-WORTHY 12V 50Ah (2 Pack) Lithium Battery, LiFePO4 Rechargeable Battery, Up to 15000 Deep Cycles, Replacement of 55AH 75AH Lead-Acid Battery, Group 22NF Batteries

Edit: I've had the batteries in use for 15 months now. I fish at least once a week, and sometimes 2 or 3 times, so I have around trips on the batteries without an issue. I don't know what more I could want from them. I bought 2 of the 12 volt 50 ah batteries about a month ago to run the Minn Kota Maxxum trolling motor on my boat. This TM is rated at pulling 42 amps on high, so that's getting close to the max these batteries can provide. Of course, I have them hooked in series to provide 24 volts. I have used the boat on 5 trips since installing them, and they have worked without issue. I usually run the TM on the lower speeds, but yesterday I went to a lake that is electric only and I had to make several long runs with the TM on high. Again, it worked without a problem. These batteries are about the same price as the cheapest lead acid marine batteries. The 2 of them together weigh about 25 pounds compared to 120 for the lead acids they replaced. Looks like a great buy at this point.

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

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.

I bought two batteries when they were on sale. I also got the eco-worthy charger with them. I got them March 1st 2024. By May 5th 2024 one of the batteries is completely dead. I've only used them probably five times for lights and a fish finder. I have messaged the seller they asked me if I used to own meter. I said I did. I'm still waiting on contact now update my review accordingly.

When the battery initially arrived it wouldn't take any charge, not sure why, but after depleted it once, it works fine, was able to pull 46ah before the voltage drop to 12.6v, load range from 1a to peak 20a.

Large display great 5 star great product

I received the batteries well packed an undamaged, lite weight about 12lbs. had to charge them took about 2 hrs each. I got them for my trolling motor. I have not used them yet but hopefully they will be a great purchase. That is the only reason I gave them 4 stars, will update after I use them.

They hold a good charge and last a long time
