The DM1230 should be installed as close as possible to the auxiliary battery to minimize voltage drop. Use the included D+ or ACC terminal to trigger the charger when the engine is running. For vehicles without a D+ signal, the unit can be configured to sense alternator voltage or vibration. Professional electrical installation is recommended.

Is this a genuine original part?

This is a premium TBB Power Nemo series product, manufactured to high industrial standards for vehicle power systems.

How do I know if it is compatible?

If you have a 12V vehicle and wish to charge a 12V leisure battery (Lithium, AGM, or Lead-Acid) at up to 30A while driving, this unit is compatible. It is specifically designed for vehicles with Smart Alternators.

Does it support Lithium (LiFePO4) charging?

Yes, the DM1230 has a dedicated Lithium charging profile (14.2V Absorption / 14.0V Float) and includes a "wake-up" mode for depleted Lithium batteries.
