How much is too much voltage from chargers 14.6v?

Wondering if a converter charger or solar controller putting 14.6v into Lithium batteries is too much for the fridge, water heater, furnace and 2000w inverter?

Odds are you'll probably be ok. However, we had the same concern.

FWIW, Battleborn recommends not floating their lifepo4 batteries at 14.6v for more than 2 weeks. As a result, we passed on the Progressive Dynamic single-stage 14.6v lithium converter and kept our 3-stage Progressive Dynamic 13.2v/13.6v/14.4v converter to use with our lifepo4's. We charge them at 14.4v (using the Charge Wizard) for 2-4 hours (99% SOC), then we float them at 13.6v until we need to bulk charge again---maybe 2-4 days later.

Sure you can charge lifepo4's to 100% SOC using 14.6v. However, what do you gain by doing so? Unlike lead acid batteries, Lifepo4's don't do well sitting around for long periods of time with a very high state of charge. They do best stored long-term with a ~50% SOC. Ultimately, I just don't understand all the hoopla about using a lithium specific 14.6v charger for lifepo4's---especially the single-stage versions.
