the quality of these will surprise you. very lite and easy to install. with the right charger they don't take long at all to charge. Such a great design and function well under a load.

Use:Battery swap and UPGRADE for 36v gold cartQuantity:3Weight:-22lbs each! (For a total of 66lbs)-I switched from 6 Interstate lead acid (55lbs each totaling 330lbs) losing 264lbs from the cart and it certainly feels it!Charger:-Updated to an on board charger (15amp Noco Genius "Gen5x3")-I keep it connected to my batteries and simply plug it in when I'm done using the cart. It charges each battery individually and stops charging individually as well.-I'd go bigger maybe 20amp or 30amp if you want a fast charge. It works well, but it did take aprox 14-16 hours to charge them back to full after the trip mentioned below.Practical test:-On 07/12 the wife and I took the cart out on a date night The new batteries on a full charge read right at 42v on the voltage meter.-That night we drove 24.2 miles over the course of 4 hours averaging 14mph with LED headlights ON-When we got home and they read at 39.1vPARTS USED FOR BUILD:3 of these batteries- $187.99 each1 Noco Genius "Gen5x3" $187.991 Pair of 8in wires (golf cart wires)-$121 Pair of 14in wires (golf cart wires)- $142 Longer terminal bolts(aprox 1.25in)- had'em1 Master kill switch- $13-This helps make sure not of my accessories aren't leaching my batteries-IMPORTANT: Using this became the connection point from the far end of the sequenced battery + side to the positive cable coming directly from the cart (I would have had to buy a very long cable, one and then connected them with a creative solution) GET the SWITCH.GRAND TOTAL for swap:$790.96NOTES:-The bolts (Phillips head) that the batteries come with are pretty short but worked for all the terminals that were minimally occupied (battery charger &battery charger and cable).-I had to use some longer ones on the terminals that I tied my accessories intoOPINION:I was extremely skeptical making the switch and opening the money. I could find but 1 other review that did this swap, it was very helpfulDo the swap! If your hesitant it's understandable but these are less expensive (overall), light in weight (your cart will go faster) have better longevity and can run for longer periods. I believe the batters would have kept running after the trip mentions above.I am so glad I did! For the money the outperform lead acid, save a ton of weight on the cart and should last 3-5x times as along!

They are larger than the lead acids that came with the Ryobi RM480e but it does fit if you remove one of the metal pieces inside the tray. There's a great video on YouTube that shows how it's done. They weight less than half the weight of the original batteries and can stay charged without leaving it plugged in all the time. This allowed me to put it in the shed and use it a few times before I needed to charge it up. You will need to buy a lithium compatibles charger. Just search for EZ Go chargers. The charger I got worked and all I had to do was break the little tabs inside the port of my Ryobi to fit the new charger in. I just reconnected the wires that were on the old batteries exactly the same. It started up and felt like it had more power than when I first got it. Going up hill with less weight was a big difference. The gauge on the Ryobi doesn't work properly with these but the charger knows the state of charge. I would give these a try.

Bought 2 for my 24 volt trolling motor put them together and used for 5 hrs. Came home checked them . Still 100% charged . Then boat sit for a month . Batteries where still strong but I topped them off for full charge. Had little issue on my next trip .it just stopped working. Checked with motor one battery was low power. Strange. Sent email to them . They quickly answered and replaced my battery within a week . Great service. Very light Batteries. Love them so far.

DEFECTIVE PRODUCT THAT DOES NOT LAST 2 YEARS AND SELLER DOES NOT HONOR THE 10 YEAR WARRANTY!THEY WORKED GREAT FOR JUST UNDER 2 YEARS BUT THEY WILL NOT HONOR THEIR ADVERTISED WARRANTY!DO NOT REMEND THIS PRODUCT AS ADVERTISED!

So far so good. I'm running a 48v array and they work as intended. Excellent buy for the price.

Going on 2 yrs using 2 of these batteries wired in series for 24v. They power my MinnKota Ulterra 24v trolling motor. I'm not a pro fisherman, but I troll a lot when I go fishing. I don't think I've ever put a dent in their capacity. I've even fished a 3 day weekend w/o charging them and didn't have an issue. AND, the 2 of them weigh less than one group 27 lead trolling battery. So it's a no brainer for me.

Battery worked awesome while it worked..... After 15 months it quit charging and I couldn't get it to "Wake Up" the company did me a solid and sent me a new battery to replace it for a small fee..
