Good day! Question, can the already installed charging port on the mower be used? I'm waiting on my battery to make the conversion. I was thinking of adding the triangle plug to the Lifepo4 charger and charge it that way. Or do I need to bypass the changing port? Thank you so much for your response!
For those researching, resist the temptation to install 4 12v lithium batteries in a series. this type of setup has issues and will give to trouble. A single 48v battery is the way to go when it comes to lithium.
Hello, how long and how complicated was the process? I just use mine for my home, can I install a smaller one? and I install the same size you had , what is the real running time of your setup now? thank you for your help, , have a great day
I have this exact Ryobi model mower. Anyway that you could share a link to the the battery that you bought? I heard "Double Eagle 48v" around the 9:56 mark. I went to their website and searched that but the query didn't return anything. They do have an "Eagle 1.536 kWh". So I'm guessing it has another model name on their website or perhaps that particular model isn't sold anymore. Thanks! Ooops..... just saw other's had already inquired. Sorry....
I have same model purchase made July 2020. Unit has less than 75 hours and third set of batteries still junk. Looking to expand your fleet this could be had for fire sale price of $1400. Located in central Florida south of Ocala.
Hey everyone, I have a 48v 75ah 38"that I put 48v 50ah lifepo4 batteries in and it made a click and now has blinking power and won't start, any thoughts?
you likely used 4 12v lithium batteries instead of a single 48v battery, since the lithium batteries have a bms (board that monitors and protects cells inside ) these are not always compatible with being used in groups in a series. many 50ah batteries only allow like 25amps continuous draw as well. like in golf carts lithium batteries in a series is frowned upon and riddled with issues like improper balance and shortened life. you need to charge each battery individually to get around that or you will see a shorter and shorter lifespan because when the weakest battery hits full charge it shuts off the charger and when the other battery that dint get full charge goes dead it kills the pack.
Edit: yours looks different, these ones I mentioned below may not work... original comment: Dude, they have 100 AH marine batteries LFP at signature solar, 200 amp output, 50 amp charge. Fits in these mowers. Worth looking at. I think I mentioned this on one of your vids but I can't remember.
@@kencunningham3710 I just bought new batteries, but the next time I change, I'm going with one of these batteries... I got 2.5 years from my first set of batteries, and I hope to get the same from the 2nd set.
@@kencunningham3710 I actually really love the product, other than the battery life. It wasn't a known issue when I bought. If I had known this would be the reality, I'd have bought a mower with LI batteries from the start and paid a bit more for it.
I have this exact mower and as stated after 1 year the batteries would not hold a charge anymore. It went from 3 cuts per charge to 2 cuts then 1 cut and now nothing. I just got off the phone with Ryobi and they want me to take the unit to a local service center to be diagnosed as they say the batteries last 3-5 years....Also, if it is the batteries which we all know it is, they are only warranted for 1 year so you are out of luck getting them replaced under warranty. I have 15 hours on the unit and batteries are dead. What a POS for $2600.............
Ryobi does not seem to care about their reputation. All of their new mowers are all Lithium, so obviously they know that the batteries were an issue. They should offer a kit to existing owners to convert to lithium. I have no choice but to convert mine.
@@gs1100ed Its either spend $900-1200 for new batteries and do myself or make the switch to Lithium or sell it for $500 and be done with the POC. Have not decided yet. Taking it to the dealer will involve renting a trailer there and back, time and gas just to have them tell me what I already know...
@@gs1100ed Its no different than golf carts most are still sold with lead acid batteries but some premium models come with lithium for more $$ think of gas lawn mowers.. premium ones could have fuel injection cheap ones use a carburetor.
@@fathergratwick from my perspective, it is much different. Ryobi marketed these mowers as being capable of mowing many more acres than what it can actually mow. Also, Ryobi does not tell owners to recharge when the batteries reach 50% in order to extend (lead acid) battery life. Of course, this would also reduce the amount of acreage that the batteries are actually capable of, since the acreage calculations are based on depleting a full 100% charge to 0%. Ryobi no longer sells mowers with lead acid batteries, since they know that the batteries are the Achilles heel. Ryobi does not provide a lead acid to lithium conversion option to the suckers like me who purchased their lead acid battery mower in good faith. I will never purchase another Ryobi product and will not recommend their products to anyone as a referral.
I’m on year 6 with my original lead acid batteries on my ryobi rm480ex. Only this year have I noticed some reduction in capacity. But it still mows my yard. I’d say 6 years is pretty good! Two of the batteries are testing great still, and two slightly weaker but still decent. Might switch to lithium at the end of this season though.
Great photos of 300e wiring. I am replacing my batteries and your photos have really helped me. Thanks so very much!!
Well done! I’m glad those mowers are working out fine.
Can you share links where you purchased the battery and meter??
Good day!

Please provide links to the items used!
Nice, love watching your videos. This is what I wanna do in NZ 😉

Great info thanks! For future videos it would have been better to show the work you did and the testing outside

I have been monitoring that particular fb group you mentioned for awhile. Can you talk about the savings going to electric?
Can you send the link for the new Li charger. Thanks
Why not just run the wires to the Ryobi charge port and then wire the other connection to your new charger?
Can you give me a link to this battery? I can’t find it on the website
Great video! Can you send the link where you purchased the Li battery, much appreciated!
Also any lithium battery charger is needed
The Nermak is just about the only lithium battery that will fit in the Ryobi RM300e
I have some extra mean green batteries. You think I could do a conversion like this on one of ryobis zero turn mowers?
Possibly. Those Mean Green batteries are big though and you'd have to mount them on top of the mower
Removing the seat makes it much easier
Thought about it but it didn't get in my way too bad.

Sorry. Just saw this. Unfortunately, don't need another one yet. That is frustrating about the batteries though
Can you please share exactly what model battery you bought?
All from Amazon
Any lithium battery charger is needed
Can I please get the information on the battery and charger needed
I just added links in the description
From amazon
Will this work for the RM480e?
Sure. Might get a bigger battery though

Could you PLEASE provide INFO on where to get these batteries you say fit in Ryobi RM 300e model . THANKS SO MUCH
I just added links in the description
I just added links in the description. Thank you
Nermak from amazon is as close as the original battery in all size wise width ,height, & lenght
$2000 battery for a lawnmower that cost $2200? did I hear that right?
It costs $680 every two years for new led acid batteries, so there's that expense....
@@toddmoore9138 wow thanks for the info. I saw a ryobi lead acid batter mower for sale. I"m glad I didn't pay what they were asking. appreciated.

I would love to do this but it looks very complicated :(
It's not as bad as you think. About to do our second one.
@@QuietLawn i love how he did not go with four separate batteries and choose one single 48v which is all we need.

@@gs1100ed so which one did you choose to convert can please navigate the process. Please!
thanks a lot
That's alot of screwing 😂😂 (I can only fathom what that battery cost)
Hopefully it will be worth it.
@@QuietLawn I'm heavily invested in carburetors and small engine parts at this point.
These mowers are a raw deal. Better sticking with gasoline. Two years of battery life really is not acceptable.
I’m on year 6 with my original lead acid batteries on my ryobi rm480ex. Only this year have I noticed some reduction in capacity. But it still mows my yard. I’d say 6 years is pretty good!

How? Is your yard for ants?
Don't ever tell me something works if you don't show me that it works
