This is the old battery I took out. Your friend has shared a link to a Home Depot product they think you would be interested in seeing: www.homedepot.com/p/12-Volt-50-Ah-Sealed-Lead-Acid-Battery-for-Ryobi-30-in-Riding-Mower-6-EVF-50B/319073969

@@motoshane2 thanks. Saw those after I left you a messages. Sad their out of stock and I can’t find any others. But these batteries has bad reviews.

I did find 12 v 50ah lithium batteries for 159.99 each and a 59.00 charger but not sure how to make it work.

The mower comes with 4 12v batteries each at 50ah in series already. Multiply 12v x 4 only increases voltage in series to 48v, but the ah stays at 50ah. If you stick with 4 lead acid batteries, you can't increase capacity unless you replace all 4 batteries with larger batteries, but that will not fit if your mower has no extra room. Space is what is restricting capacity with lead acid.

And you can't change the series/parallel configuration because the mower has to see roughly 48v nominal or it won't operate. Capacity can increase, but voltage can not change.

Most everything came with the Uno battery. The only things I added were wood and more zip ties.

There might be. Nothing I found would fit my mower without major alterations to the mower. Plus I get more capacity in a much smaller package. The Uno is a NMC battery, not a lifepo4. They have more capacity for their weight and size then lifepo4 and it was nearly a perfect fit. Also, the more capacity you have, the longer the battery will last since it's cycling less, due to the larger capacity. Do the math, and you'll see the cost is nearly the same with lifepo4 when you factor per amp-hour capacity.

@@motoshane2 Li-Time makes pretty direct fit LifePO4 batteries that utilize the OEM wiring, so don't need to do any changes. I was looking at the UNO previously, but the cost is too much for me personally, the Li-Times are 339 each, so I'm about to go with those in a season of two since my lead acids are still holding up fine.

I looked at their site. They sell lifepo4 batteries similar to many other companies. Both the 50ah 12v and the 12v mini 100ah are the closest for fit, but both will likely need mower frame alterations to fit the RM300e mower. If I had a larger mower I likely would have gone the lifepo4 direction. It's one of the reasons I went with the Uno. Fit is not in question. Charger and battery fit with space left over. To me, the cost was a trade off for simplicity of the install. I do agree that lifepo4 12v and 48v metal incased single golf cart batteries are great options. I just choose a different direction. Thanks for the discussion.

@@motoshane2 Epoch Batteries have a Conversion system that fits and is less that the Uno. Shipping for the Epoch is like 35-40 bucks. The bundle is 1033.** and some change. 11 year warranty! No cons going with the conversion. Only pros. 30ah of LFP4 I’ll cut about 1.25-1.5 acre with flat landscape and the thickness does make a small difference in cut time. With the 480s, you could fit 2 which = 60Ah, depends on how much you need to cut.

Uno was $32 per ah to purchase (no longer available). Epochs you suggest are $28 per ah. Epochs are 66lbs for 60ah, and the Uno is 48lbs for 90ah. Uno is .5lb per ah and epochs are 1lb per ah. I'm still happy with my purchase other than Uno is now out of business. Reducing the price down to 60ah Uno equivalent, I only paid $200 more than a set of Epochs. And I appreciate the weight and size savings, with 30ah extra range. I'm happy.

Thank you.

You are looking at this correctly. The mower is cheap compared to other electric mowers because it uses lead acid from the manufacturer. Compare to prices of mowers manufactured with lithium batteries, And those mowers are much more expensive because of the batteries. A new set of lead acid batteries is $800-$1000. Lead acid will last 2-4 years (most see 2 years). In a 10 year span, you'd break even or even save money using lithium vs lead acid, but you get double the range for the same price or less. Now the question is, can you afford $3,000 up front, or $1,000 every 3 years roughly.

@@motoshane2 Thank you.

@@shankarmohan No problem.

@@motoshane2 Quick question. Would you be able to provide charger specs for UNO Charger ? The charging voltage from manual ? The reason I am asking is to see if I can use it to charge lifepo4 batteries as well.

You will be just fine with one battery. These mowers don't pull as much as a golf cart. The highest draw I could get out of my mower was 42amps when pushing it very hard, and I can't only hit that momentarily. Even if yours pulled double the amps, that's still under 100amps continuous, let alone hitting the 200 and 500 amp surge profiles of the Uno battery. I'd just clear it for warranty purposes with Uno. Send them an email.

It depends on what I'm doing. I did pull a weighted deep spring rake around the yard 3 times, and mulched the raked thatch with 3 passed and only used 35% of the battery. I'm happy.

@@motoshane2 Have you found that the stock battery gauge is accurate for your lithium setup? Most other Ryobi to lithium conversions I've seen replace the gauge to one made for lithium/LiFePO4 batteries.

@@JustWasted3HoursHere The stock batter monitor is not accurate with lithium batteries. The uno battery has Bluetooth access to check battery status from your phone. However I did install the Uno provided wired meter. It's about 5% off, but it is useful.

@@motoshane2 Thanks for the reply and info. I am installing my gauge presently for my lithium setup (4 12V 100AH LiFePO4 batteries). Hardest part was A) Finding a local store that sells 20 gauge wire, believe it or not and B) drilling the gauge hole slightly larger to accommodate the new gauge - I bought a large stepper bit for my drill to make the hole bigger that just about ripped my arm off. Looking for another way to do this.

Mount a wooden block behind the hole you are trying to enlarge. Then the drill has a way to hold the saw bit in place while one enlarges the hold. RV Holding Tank Service

Yes you may. Thanks for asking. Please send me link.

I have another request. Would I be able to show this video at a Farmington City public hearing?

Thanks!

@@gringakathy Of course. You may download the video and edit if you want.

You have to fly it specifically to control that.

I don't believe so. Its been a while. However, the Picoblade 1.25mm is the small connector and the large is PH 2.0mm. Its the distance between the pins that is the main difference. The small is 1.25mm and large is 2.0mm.

Yes. I'm pretty sure it is.

They are LED strips. They are powered directly off of a 3 cell LIPO in this video.

They were added. LED strips.
