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.

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!

He comprado tres de estas baterías para el sistema solar que estoy haciendo en casa, el rendimiento es muy bueno con estas baterías, la calidad de construcción se nota y las pruebas que le han realizado han sido muy exactas, justo con los datos que tiene en la descripción

I needed to replace the battery in my boat I use to run my 12 inch UHD2 Garmin unit and Livescope. I have a friend who had bought this battery in a lower amp hour version and has gotten great use from it so far. I read its specifications and it seemed to be a well made battery. The price was equal to a lead acid battery instead of being the jacked up price of a pure lithium.I knew I would have to buy a battery charger either way so I ordered it. I have been using it for 3 weeks, running the 12" Uhd2, Livescope "black box" and a 9" unit. I start off my mornings showing from 13.4 -13.6 volts and after 8 hours of fishing still show from 12.9-13.1 volts and according to the charge lights on the battery case it is still at 3/4 charge.My livescope is showing up much better / brighter. So far I am thoroughly pleased with this investment. The paperwork with the battery said it could be charged over 4,000 times and should last 10 years. If it does, and I'm still able to get around then - I'll be buying another just like it.

I have to say that I wasn't expecting much when I bought them. I thought, at least I'll get some prismatic cells out of them and then replace the BMS with a better one. But I waited a year before I left this review.I built a solar generator as my gas generator never sarts every time lights go out. (My fault: bad owner) But I decided to connect my fridge for 1 year just to keep the batteries cycling. These batteries have never failed. Always provide power to have some comfort after the storms. I have Weize 1200w inverter, only consumes 4 watts on idle, and 6 - 100 watt Eco Worthy panels and Sunthysis 40 amp charge controller that keeps my batteries top off. Even after 6 days straight of storms and cloudy days, the batteries never died. 2-3 days of sun later, and they are topped off again. I like the fact that I know I can leave for a week and trust my fridge will always be powered.

So far so good. This battery has been doing all that I ask of it. I’m currently running a 600 W inverter and plan to expand my system as necessary. Will update this review if anything changes.UPDATE: 4/4/25 I now have 6 of these batteries! They all are working great! My end goal is a 16 battery bank giving me 48v at 400AH. My calculations show that this will run an air conditioner or electric blanket over night with no issues! I’m glad I chose these batteries as the price is right and the quality is great. I will say you save about 10 bucks buying from their website directly. The lowest price I’ve paid was 139.99 at the time of this update 141.99. Who knows where they will go under the new tariffs?
