Hi, I have an Epever 4129 BN, the version that has to be setup with USER parameters to work with LiFePo4 batteries. Many know the main issue is not being able to turn off the FLOAT charge in the setting, and needing to set them to a state that disables FLOAT or makes it a non-issue. It appears that the charge controller is charging at about .5 amps when in the FLOAT state. My question is, is this safe for my batteries? Am I ok to leave the setting I do have for long periods of time without causing damage to my batteries. Here is a snap shot of the Epever readout.

Ok, i guess nobody knows if having a float current of half an amp is ok.
 
There should be no current flowing once the battery reaches the target voltage.
Maybe the target voltage is set too high.
