| Vehicle | 1993 Snapper Rear-engine rider Well-worn 25" cut riding mower that I traded for. |
| Motor | Perm Motor PMG-132 Permanent Magnet DC |
| Drivetrain | Stock. Blade drive pulley was changed to keep cutting speed the same. Perm motor on 48V runs at 2300 rpm versus stock engine at 3500rpm. |
| Controller | Two SW-80 contactors are used. The starting contactor is in series with (2) paralleled 2-ohm resistors to limit inrush. Then the run contactor can be switched. |
| Batteries | 4 Deka 8G24M, 12.00 Volt, Lead-Acid, Gel |
| System Voltage | 48 Volts |
| Charger | Soneil 4808SRF Charge voltage pot must be adjusted to work properly with gel batteries. |
| Instrumentation | Fluke DVM |
| Top Speed | 3 MPH ( 4 KPH) Stock is about 4.6 mph. |
| Range | About 1 hour of grass-cutting. |
| Seating Capacity | 1 adult + 1 child on my lap |
| Conversion Time | 1 1/2 years |
| Conversion Cost | motor $900 batteries $600 contactors $60/ea charger $175 wiring $125 |
| I measured the killowatt-hours to recharge the battery using a Brand Electronics meter. Less than 2.5 KWh for my 1/4 acre lot, which takes about an hour to finish. That's less than $0.25 per cut. | |
