AJK Offroad Battery Isolator / True Am
The AJK Offroad Battery Isolator — known as the True Am — is an easy-to-install dual battery management isolator that keeps your second battery from draining your starting battery. When the engine is running, the True Am charges both batteries simultaneously. When the engine is off, it isolates the second battery from the first — so winches, lights, and accessories draw from the second battery only, leaving your starting battery always ready. The core component in any AJK dual battery kit.
Key Features & Benefits
- Simultaneous Charging — When the engine runs, the alternator charges both the starting battery and the second battery at the same time
- Battery Isolation When Off — Accessories draw from the second battery only — the starting battery is never at risk from accessory draw
- Easy Installation — Simple wiring connections — no complex relay wiring or programming required
- Voltage Sensitive — Automatically connects and disconnects based on charging voltage for reliable, hands-free operation
- Used in All AJK Dual Battery Kits — This is the exact isolator included in AJK machine-specific dual battery kits
