Mastervolt BattMan Battery Monitors for Precise 12V and 24V Battery Management in Marine RV Solar Systems
Mastervolt BattMan Battery Monitors are essential tools for real-time battery management, offering precise monitoring for 12V and 24V DC battery systems. Designed with a large, splash-proof (IP65-rated) display, these monitors provide critical insights into battery performance, helping users maintain optimal power usage. Available in two versions — the BattMan Lite and the BattMan Pro — these monitors are ideal for marine, RV, and solar applications, offering flexibility and advanced battery tracking features.
The BattMan Lite displays essential metrics, including voltage, current, amp-hours, time remaining, and battery capacity percentage. For those seeking more advanced monitoring, the BattMan Pro offers all the same features plus the ability to collect historical data, display special battery status events, and provide a real-time countdown of the remaining time before the battery requires charging. This ensures users are never caught off guard by a depleted battery bank.
Both models support two battery outlets: a fully monitored service battery and a starter battery (voltage-only monitoring). With a wide voltage range of 0-35V, these monitors are compatible with most 12V and 24V battery banks. While the BattMan series is not MasterBus compatible, it does require a 6-wire connection cable for proper setup. Offering easy-to-read data and advanced power management, the BattMan Pro is ideal for users who want detailed insights into battery health and energy usage, while the BattMan Lite provides a simpler, budget-friendly alternative. Whether you’re managing a marine vessel, an RV, or a solar-powered system, the Mastervolt BattMan monitors keep you informed and in control of your battery power.
