Lithium chargers are based on a CV/CC (constant voltage/constant current) charge algorithm. While lead-acid offers some flexibility in terms of voltage cut-off, manufacturers of LiFePO4 cells are stringent on the correct setting because Li-ion cannot accept overcharge.

The differences with Li-ion relate to the higher voltage per cell, tighter voltage tolerances, and the absence of trickle or float charge at full charge. A lithium battery at 20% capacity will hold voltage around 13V lead-acid will be around 11.8v at the same capacity.Ī Lithium LiFePO4 charger is a voltage-limiting device that has similarities to the lead-acid system. A lead-acid battery will be around 12.6-12.7v. While the PEC may safely "charge" Lithium batteries (somewhat), as stated on WFCO's website, the PEC is not designed for Lithium Charging and by Forest River's own engineer's statements, does present quite a few shortcomings for Lithium use.Ī 12v lithium LiFePO4 battery fully charged to 100% will hold voltage around 13.3-13.4v. The PEC is designed and sold as a Lead-Acid Charger, and by that definition alone, disqualifies the PEC as a Lithium Ready Charger and disqualifies the IBEX 23RLDS as a Lithium Ready Travel Trailer. Many specifically state that a "Lithium Charger must be used." Lithium Battery warranties don't cover improper charging.
The Lead-Acid algorithm does not have a Fast Charge state.
The Parallax units today are descendants of the original three-current stage converter/charger dating back to the early 1970s, though they may not have used the “marketing” term that is used today by other manufacturers. Our products have always been made in North America and built with steel enclosures, just as residential and industrial electrical systems are today. This includes companies such as Phillips, BW Manufacturing, and MagneTek™, which give us insight and experience that newer off-shore converter manufacturers simply cannot draw from.
