I found this forum by searching for others who had taken the leap and converted their Ryobi lawn tractors from SLA to Lifepo4 batteries. The detailed information posted by @AMDPower, @UltrasoundJelly and others users has been a great resource. Our 48v lawn tractor came with four LEOCH 12v 75Ah SLA batteries. After four years of use, our four original batteries are in very bad condition. These are the test results for the four batteries after a full charge:
1. 96% SOC - 38% SOH
2. 96% SOC - 31% SOH
3. 99% SOC - 29% SOH
4. 100% SOC - 26% SOH
We found what looks like a good replacement at a very reasonable price. Eco-Worthy offers 12v 50Ah Lifepo4 batteries for $199 which is less than buying replacement LEOCH 12v 75Ah batteries from Home Depot. Considering that the depth of discharge for Lifepo4 can be over 90%, compared to around 50% for SLA, it seems that we would have more available power with these than with the original batteries.
$800 to replace all four batteries with free shipping seems like a great solution. We would greatly appreciate help to confirm (or not) this from someone who has more experience or knowledge than we do.
