This is absolutely succinct. An admission of stupidity from a battery charger manufacturer who declares the word "Boon-Dock" to not be in their dictionary. To them, Power Pedestal Princess is on their mast head

If they do not recognize the word they certainly haven't a clue as to how to go about engineering a device to charge batteries. Read their brochure comment again.

Only way to tell is test it.

is provided for the rare times a

charging. See wfcoelectronics.com

this means a very deep discharged battery may induce 14.4v

I had a wfco 98100, that I installed
And yes it would goto 14.4v bulk mode
The battery charge wiring is "1 aught"
Came that way from the factory, with the OEM installed Freedom 10, 1000w inverter, 50 amp charger
Which I had to replace after burning up the pass thru circuit
(My fault)

Now that's ironic! I am sitting here reading the owners manuel for the WF 9800 series converters. Our new TH has a WF9875 (75 amps). The manuel says it has three modes...on of which is 14.4.

Interested in seeing others opinions for this as well.
