Nice job! Surprised you had enough room to even put the charger in there! That's great.

Ok… Another question. Is there an good way to survey for shade obstruction? I’m wondering if there is a Raspberry Pi script or anything out there that could monitor a panel output throughout the day. I’d like to get the optimal output from the E vs. W installation and do have some trees.

Hi All! You guys were super awesome in helping me design and convert my Ryobi Zero-Turn mower over to Lithium. That post completely blew up and helped a ton of others as well. Well, now I am getting ready to install my first Solar System! It will be on my garage roof (unfortunately facing...

Wow! That's a great deal! Sounds like you definitely have some weak batteries. Most of the drop-in replacements will work with little effort. Just make sure they are compatible with a 4S configuration (4 batteries in SERIES). However, you can probably build your own for half the amount of...

@ryobilifepo4user Why are you using that tiny little charger? I think the proper procedure with "drop-in" LiFePo4 batteries is to hook them up in parallel for a few days (if supported) to let them balance. After which, just put them back in the mower and use the Ryobi charger. Yes, it may...

I seriously cannot believe the interwebs sometimes. I started this thread with a question that I assumed was extremely niche but got valuable feedback. After which, I saw multiple people do similar builds (and some a lot better!) for the mower that I didn't think anybody else even had. Crazy...

You should be fine. It's a little much for the LiFePo4. Actually charges at 56+ I think. But the BMS will cutoff prior. Only problem is that the Ryobi charger will sometimes go into an error state when the BMS kicks it off. That's what I found anyway.

Good job everybody! Just saw the new builds! They look great! Also, would like to report that I left mine off the charger all winter with the LED battery display powered and it basically didn't even budge. Ready to rock this year as well!

That's a wild configuraton for the Ryobis! Looks like it has (3) 80V 10 AH batteries on-board for 30AH runtime and then you can use their regular 40V packs and add 4 of those at 12AH a piece. That should give a total of 54AH capacity which they claim is able to mow 4 acres (at 80V). Likely...

Mine was simply the charger connecting to the battery "live" and tripping the GFCI. I just make sure to attach the cable before turning the charger on and no problems occur.

Really?! Awesome! Didn't know they made one yet. Sweet!

Nice find. Thanks!

@Nandologist I'm not sure where prices are right now but building it yourself shouldn't be twice the amount of money. I ended up spending $1100 vs. $800 for AGM. And I shouldn't need to ever worry about changing batteries again. I would get the use out of your existing batteries but if you...

My wife was not happy either! I was really worried about DIY but really glad I did in the end. I was able to do it for just over $1000 and with very good components. Not much more than lead-acid. If you don't want to use wood, you could use a plastic with L-brackets for the frame maybe. I'm...

Oh... My bad. I just noticed those were 48V! I thought you were doing 4 12V batteries. I'm sure you can find another method of securing it.
