Mastervolt - BATTMAN LITE Battery Monitor

Product details

High-precision battery monitor with large, splash-proof display (IP65), which shows all important battery bank information (voltage, current, amperes and battery capacity in %) and sounds an alarm when your battery bank is empty. For example, an audible alarm or a matching relay for the deep discharge protection can be connected to the alarm output. Power supply: 9-35 V DC. Dimensions: outer Ø 64 mm, installation Ø: 52 mm. Installation depth: 73 mm. Supplied with 500 A shunt.

The Batman can also be used for lithium-based batteries.
In the basic settings (step F7), the factory-set Peukert value of 1.25 must be set to 1.00 for this purpose.

wie tief muss ich die Batterie entladen?
The battery monitor shows me, among other things, the percentage of charge and the required AH number that is required for a full charge. The display, which is illuminated if necessary, is easy to read from a straight viewing angle, even in semi-darkness. I charge the battery almost exclusively via the alternator or the solar panel. The solar controller ensures compliance with the auto sync parameters described under F02 and F03. Now the 100% was reached prematurely, so that the percentage display jumped to 100%. Is it possible that the battery has lost capacity? And how do I know that? You write that a full charge cycle is required for synchronization. I miss the information about how deep the battery has to be discharged. I've been using the display for 2 years now and still don't know whether the 100% SOC only relates to the set Ah number or whether it is updated automatically depending on the state of the battery. The set parameter F01 always remains at the set Ah number. Thank you in advance for your efforts to answer my question. Peer life

Yes, MASTERVOLT recommends in set up step F07 to set the Peukert factor for lithium batteries from standard 1.25 to 1.00.
