How deeply do I have to discharge the battery?
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

Lithium iron phosphate batteries on boats and yachts - properties, special features and use
The lithium iron phosphate battery (LiFePO4 battery) or LFP battery, is currently the best in the battery sector. A basic distinction is made between conventional lithium-ion batteries and the newer generation of batteries, lithium iron phosphate batteries. The terms lithium-ion battery and lithium iron phosphate battery are often used interchangeably in everyday language. However, this generalisation is not correct when comparing the two types of battery directly and with regard to their chemical and technical structure. Both battery types have decisive differences. In this guide, we explain what these are in detail, which battery type has which advantages and many other details, especially about lithium iron phosphate batteries.
