48 VOLT TWIN MOTOR TWIN 500 AMP CONTROLLERS ON LITHIUM POWER

IM ALL IN! You guys have paved the trail so now I think it’s safe to travel!

Last year I purchased a 2010 Bad Boy XTO. It was in fantastic condition other than a very rusty battery compartment….ie entire frame surrounding the batteries…… and a bad controller and contactor.

Buggy worked great all summer and thru this winter hunting season. Range steadily decreased from 7 or so miles to about 2.5…..hunting season is now over and the tired original batteries have been pulled.

FYI the batteries were branded Bad Boy but were Crown 245 ah 6 volts.

All rust scale removed cleaned as best I could without complete disassembly and two coats of rust bullet applied.

CURRENT SPECS

• Twin SEPEX motors reported to be about 19 HP each (**** that seems like a lot!)

• Twin SEVCON Millipak controllers rated @ 65 volts input and 500 amp output

• 24” semi aggressive tires…..measured height……

THE PRELIMINARY PLAN

• Keep the electronics as is with some relocating and waterproofing
• Install Nissan Leaf 53V nominal pack (7 modules or 14)
• Install aux 12V AGM for winch, lights, thermal imager and other misc electrical loads

CURRENT STATUS

• Old FLA batteries removed
• Partial disassembly and rust remediation done
• Battery compartment sealed from MOST mud and water intrusion
• General wiring cleanup and housekeeping done
