Charge wizard with Lithium upgrade to Converter charger?

The Progressive Dynamic EQ mode only applies 14.4v for 15 min every 21 hours before dropping back down to 13.2v or 13.6v. Battleborn only expressed concern about floating their LifePo4's at 14.6v 24/7, weeks/months at a time. Very significant difference.

IMO, anyone with a LifePo4 who has the need to leave their rig unattended for weeks, months at a time should simply disconnect them--ideally with a 40-50% SOC, regardless what kind of converter/charger they have. With a parasitic discharge rate of only 1-2% a month, they'll be fine for a very, very long time---at least a year or more. Even 13.6v will quickly float LifePo4's to 97-98% SOC. Unless I'm missing something here, what's the point? Is it possible this is the reason Progressive Dynamic designed a single-stage 14.6v converter to begin with? They saw no urgent need to float a LifePo4?

Agreed, I disconnect mine while in longer term storage...Charging a LiFePO4 is slightly different than FWC’s, but once one gets past the keyboard mythology (lol :) ) it is in no way difficult....

I like my programmable inverter with all the wants of your dream converters. ;)

Great idea! 3-stage: 0/13.2v/14.2v. A totally programmable version (with a zero volt option) would be ideal. I would prefer a 14.6v bulk mode.

Called Battleborn and it is a single step charging with the Lithium upgrade. They said PD is working on multiple step converters, but it's not available for mine yet. Working it out for return of the PD4560Licsv. They are always courteous and helpful.

Should be 2000 watt inverter from Renogy.

If you have a progressive 3 stage charger and plug in the progressive charge pendant you can charge lithium batteries. By pressing the charge pendant, the charger will go into boost mode 14.6 volts and after 4 hours return to a safe 13.6 float charge. Progressive recommended this to me instead of replacing the charger with the lithium charger.

That's is what I have been doing. Not happy about a constant 14.6v and possibly frying my appliances. Also have a 200 watt Renogy inverter attached to the batteries. Not sure how it likes that voltage either.

I believe hpdrver has a conventional PD 3-stage converter (13.2v/13.6v/14.4v; each selectable using the Charge Wizard). If he has the PD converter that switches between conventional 3-stage and single-stage 14.6v lithium, it will not drop to 13.6v in the lithium mode. He must select conventional than use the Charge Wizard to select 13.6v.

Have you had a chance to verify the voltage output of your PD4560Licsv when you switch modes with the Charge Wizard?

Don't believe Renogy currently makes a 200w inverter. Did you mean 2000w? Most Renogy inverters have at least a 15.0v input rating. Some are rated as high as 16.0v.

I believe most (if not all) 3-stage Progressive Dynamic conventional type converters/chargers made by Progressive Dynamic bulk charge at 14.4v, not 14.6v.

Some of the 3-stage PD converters are conventional/Lithium switchable. You can choose conventional charging at 13.2v/13.6v/14.4v or 14.6v lithium single-stage charging, but not both at the same time (if it did have this capability it would make it a true 4-stage converter/charger).
