I purchased a JS-C33 power display to use as a state of charge monitor for my LFP battery. Given that LFPs have a very flat voltage rate discharge vs LA, how accurate is the % of battery display on the unit? I have followed the guidelines and set mine for F-4 on menu 1.

Hello Bjorski,

Please check if it is this item, https://www.amazon.com/dp/B07759SLYP?ref=myi_title_dp&th=1

It calculates capacity percentage by monitoring battery voltage.  F4 is for 12.8v LFP battery, if your battery type meet that, it should show correct percentage. Or please choose custom setting, menu “3–“.

Best regards.
