My AGM to Lithium conversion
Here is a quick article I wrote on my adventure going from AGM batteries to Lithium. http://rvbprecision.com/rv-projects/rv-lead-acid-agm-to-lithium.html http://rvbprecision.com/rv-projects/rv-l...

Some think it is ok to zero% and experience shut off--except this LFP brand's BMS cuts off higher than that at 5%. There is a lot of confusion over how far down is zero!
Scroll down a bit for the general specs. Bulk cells on Alibaba
A pre-made battery may allow cells a little beyond the range or a little inside. That is a warranty call made by the builder.
OK, so the monitor measures SOC based on total voltage of the cells, but BMS uses lowest cell.
If not been to 100% and balanced for a while like itinerant1 operates, what is the risk the monitor will not warn in time before BMS LVD?
And that is top balancing
