The voltages the charger steps through — absorption (the full-charge stage), then float (gentle hold) — plus a low cut-off. LiFePO₄ needs values set to its own spec.
Lithium does not charge like lead-acid. Setting the right absorption, float and cut-off voltages keeps the bank healthy and full — wrong values shorten its life or leave capacity on the table.
The charge profile is entered into the MPPT and DC-DC charger and the battery monitor, matched to your specific LiFePO4 cells.
Design your van, boat, cabin or RV system in Wattonomy and it outputs the exact absorption, float, tail-current and cut-off values to enter into your chargers and monitor — from the appliances you actually run, sized to the recognized standard for your region. You see it on the wiring diagram, in the sized parts list, and in a plain-English build pack that explains the reasoning behind every choice. No account, no email — about a minute to a complete, validated design.
Typically a low absorption voltage held briefly, then a low float (or none), with a low-voltage cut-off — but always to your cells’ datasheet. Wattonomy gives the commissioning values for your design.
No — it can overcharge or undercharge the cells. Lithium needs its own absorption, float and cut-off settings.
