What are the steps for converting a Ryobi riding mower to a lithium battery?
Steps for Converting Ryobi Riding Mower to Lithium Battery:
1. Take photos of everything during disassembly.
2. Remove the battery. Those old batteries are HEAVY - use your legs.
3. Install the new battery and reconnect the wiring exactly as it was before.
4. At this point, the mower should work—test it to ensure everything is functioning properly.
Can the original charger be used for lithium batteries?
No, it's recommended to use a dedicated lithium iron phosphate (LiFePO4) charger for charging Enjoybot batteries.
Should a pre-charge circuit be installed?
When replacing the battery of a Ryobi lawn mower with a lithium battery, a pre-charging circuit is recommended to prevent a large inrush current from damaging the battery, electronic components, or the motor controller.
