Q: Can this charger work with "Smart Alternators"?
A: Yes! The VoltMaster 25A is fully compatible with modern smart alternators (Variable Voltage Alternators) found in late-model vehicles.

Q: Can I connect solar panels and my vehicle battery at the same time?
A: Absolutely. The charger features dual-input technology and will automatically manage the power from both sources simultaneously to reach the 25A output.

Q: What happens if my Lithium (LiFePO4) battery goes into sleep mode?
A: The VoltMaster includes a LiFePO4 activation feature. If your battery’s BMS has tripped due to low voltage, the charger will send a pulse to "wake" the battery and resume charging.

Q: Is it waterproof?
A: The VoltMaster is rated IP67, meaning it is fully sealed against dust and can withstand immersion in water, making it perfect for under-bonnet or external mounting.

Q: Do I need a separate solar regulator?
A: No. The VoltMaster has a high-efficiency MPPT solar regulator built-in. Simply connect your solar panels directly to the solar input.
