Detailed description
Detailed description
The Mastervolt BattMan Lite is a battery monitor designed to provide essential information about the state of your battery bank. Suitable for 12 V and 24 V DC systems, it features a large, IP65 waterproof display for easy reading in a marine environment. This monitor is compatible with lead-acid and lithium (LiFePO4) batteries, offering flexibility for various nautical setups.
Monitoring Features and Accuracy
The BattMan Lite provides precise monitoring with a maximum capacity of 9999 Ah. It measures the voltage of two batteries (service and starter) and the current of one battery, displaying voltage, current, consumed amp-hours, and remaining capacity percentage. Voltage accuracy is ± 0.3 % and current accuracy is ± 0.4 %. Its current measurement range is 0 to 500 A, with a 500 A/50 mV shunt included.
Display and Integrated Alarms
Equipped with a backlit display, the BattMan Lite presents information clearly and universally. A visual power bar complements the numerical data for quick understanding. An integrated warning function alerts to excessive battery discharge, helping prevent damage. Additionally, a programmable dry-contact alarm relay can trigger external actions, such as starting a generator, when the battery reaches a predefined discharge threshold.
Installation and Limitations
With dimensions of Ø 64 mm for the monitor and 87 x 45 x 35 mm for the shunt, installation of the BattMan Lite is simplified by a quick-mount system. It weighs 0.15 kg. This model does not provide remaining time indication or historical data, and it is not compatible with Mastervolt’s MasterBus system.
