Simple Ryobi RM480e Battery Replacement in 15 Minutes – Single 48v Lithium w/ LiFePO4 Charger!

Описание: The original version of this video featuring the stock charger is here:    • Simple Ryobi RM480e Battery Replacement in...  
Following the simple steps below, we were easily able to convert our failing electric riding lawnmower into one which:
Requires no modifications to the factory wiring of our Ryobi mower
Cuts our 1.25 acre yard twice before needing a recharge (at around 30%)
Can be charged with both the stock charger OR the DCHouse LiFePO4 charger (you choose)
Charges at .25% per minute (for example, from 25% to 100% in only 4 hours)
Has an advanced Bluetooth battery management system that protects our investment
No longer needs to be plugged in when not in use
Replaces 4 heavy lead batteries with a single lithium battery protected by a 3 year warranty

STEPS: (Similar for 48v Zero Turn mowers such at ZT480)

Our Choice of Charger
This is a follow up video to our first video which uses the stock charger.    • Simple Ryobi RM480e Battery Replacement in...  
The intention is to show how LiFePO4 chargers can be used in this conversion without having to modify the stock circuitry of your mower.
You get to use the existing charger wiring as-is, with zero modifications.
The DCHouse charger is on par to the Ryobi stock chargers in quality.

Our Choice of Battery (DCHouse 48V 100Ah)
We chose to go with the DCHouse battery because of price and positive feedback in the group. It seemed to be a new arrival to this battery form factor and people in the group were speaking highly of its BMS/Bluetooth app. We chose 100 AH because we have a 1.25 acre plot and wanted to have more than enough coverage. Here is a great write-up on the DCHouse BMS:

Battery Meter
We chose not to add any battery meter (including the one that came with the battery). The Bluetooth app that came with the battery was more than enough for our purposes. At any time we can take out our phone and see a realtime summary of the state of our battery and we always have plenty of capacity for our yard.
Here is the manual to the Bluetooth app: https://tinyurl.com/2mjkdhyj

Overall Outcome
We love our newly upgraded mower, all of the changes are for the better. The main problem of the battery running low during use are now gone. The performance is better during the mow, it is faster and never bogs down on hills (and our yard has many). Now we charge it to 100% and then use it until it gets down to 20-30%, charge it over night and then unplug it after the charge is complete. In addition, we no longer have to keep it plugged in when not in use.
