Upgrading the Battery Monitor in a Lithium Ryobi Electric Riding Lawn Mower

Previously, we upgraded the Ryobi Electric Riding lawn mower from lead acid batteries to lithium. Now, we'll upgrade its battery monitor to properly measure the new batteries.

If you already bought this mower, the best thing you can do is replace them! With Lithium Batteries! Links below, but some details you should know first. Updates: Officially, LiTime reached out and asked me to state that they officially do not support using their batteries for lawn mowers and may not honor their warranty if you do. However, I have also seen them advertising their batteries for this exact purpose. Use them at your own risk, I've linked other brands below as well. Also, if you have Ryobi's RM300e or RM480EX, scroll pass my initial battery recommendations to sections about those mowers. I've also linked a popular "Single battery" Chins and "Single Battery" LiTime option. These batteries requires additional work to install as it doesn't fit perfectly, but as it's a single battery the wiring is easier and you don't have to worry about balancing. You probably will not need to do the key fix that I had to do, these randomly fail and that's what happened to me. Only do this if necessary. For clarity, I have model RY48111 but the following batteries should also work for models RY48110, RY48112, and RY48113. I'll discuss some other models further below. Battery options (I used the LiTimes, but these others should work too) LiTime (on amazon buy the four pack): https://amzn.to/45jPE6c (affiliate) LiTime: (direct from website, buy the four pack): https://shrsl.com/4vu36 (affiliate) Chins (buy four): https://amzn.to/3yvytRr (affiliate) Mehrpower (buy four): https://amzn.to/4fz1a0x (affiliate) Single Chin Battery: https://amzn.to/3SIy3Om (affiliate) (requires additional work to install my guide does not cover, but avoids balancing and BMS issues) Single LiTime Battery: https://amzn.to/3PHijJu (affiliate) (requires additional work to install my guide does not cover, but avoids balancing and BMS issues) Single Digi Marker Battery, includes monitor and charger: https://www.digimarker.com/products/%...

The general recommendation appears to be this single battery: DC House: https://amzn.to/42ALJ3l (affiliate). I suggest following this video:    • Simple Ryobi RM480e Battery Replacement in...   **Second Note: If you have Ryobi RM300e 30-inch 48V mower, this battery is recommended but will require some work to make fit, including removing remove the center pieces of angle iron from the battery compartment. https://amzn.to/4dsLqNW (affiliate) However, this 30AH battery without removing the angle iron: https://amzn.to/4dwH3kY Battery charger: https://amzn.to/3PgyGzP (affiliate) Make sure to set the battery charger to 48v and 10a/8a. Also: Rather than switching the charger head housing as I did, you can instead break the two plastic tabs inside the Ryobi's charging port, and then the new charger will slide right in with no rewiring required.
