Other findings

Bulk charge voltage
14.4 V in Bulk, entered only from a discharged battery

“If the output current reaches its maximum (normally caused by a discharged battery), this will cause the converter to go into Bulk Mode, which means the target output voltage will change to 14.4 VDC and a timer will start.”

Bulk mode duration
Bulk ends at about 5 A of draw, or after 4 hours

“Bulk Mode will be maintained until the current draw drops to approximately five Amps, or until the timer reaches four hours (whichever happens first). Then the target output voltage is changed back to 13.6 VDC for Absorption Mode.”

Charging stages
Three stages — Bulk, Absorption, Float

“The 3-Stage “smart” charger continuously measures the battery voltage output and regulates the amount of charge using three modes of operation; Absorption, Bulk and Float modes.”

Designed for battery type
Drawn against a 12 V deep-cycle battery

“12 Vdc DEEP CYCLE BATTERY”

Nominal output voltage
13.6 V nominal — the mode it holds in normal use

“The converter normally provides a constant target output voltage of 13.6 VDC (nominal) to power all the branch circuits.”

Output voltage verification
13.6 V ±0.2 with no load means it is working

“If the voltage reads 13.6 VDC (+/- 0.2) with no load, the converter is functioning properly.”

Vehicles the manufacturer names for this charger

  • Forest River publish the WF-8900's operator manual in this model's own component list, alongside the WF-8930/50 distribution centre and a Rich Solar controller and panel. Their owner's manual for the model says the converter is also the charger: "The power converter also operates as a battery charger when the RV is connected to a 120VAC power source or a generator."

Figures compared — they do not meet

Neither maker names the other. What this charger publishes and what these packs publish do not meet, and each row below says how. That is our comparison of two documents and not a manufacturer’s refusal — check both against your own equipment before deciding anything.

Redodo state this pack's charge voltage as 14.4 ± 0.2 V — their datasheet reads "Charge Voltage: 14.4V±0.2V". WFCO's own manual gives this converter a target output of 13.6 VDC in normal use, rising to 14.4 VDC only in Bulk Mode, which it leaves "until the current draw drops to approximately five Amps, or until the timer reaches four hours (whichever happens first)". So the converter's normal output is below what this pack is specified to charge at, and 14.4 ± 0.2 V is reached only during that Bulk phase. Neither company names the other, and neither has said anything about this pairing.

Renogy state this pack's charge voltage as 14.4 V to 14.8 V in cycle use — their datasheet reads "Cycle Use Voltage 14.4V to 14.8V". WFCO's own manual gives this converter a target output of 13.6 VDC in normal use, rising to 14.4 VDC only in Bulk Mode, which it leaves "until the current draw drops to approximately five Amps, or until the timer reaches four hours (whichever happens first)". So the converter's normal output is below what this pack is specified to charge at, and 14.4 V to 14.8 V in cycle use is reached only during that Bulk phase.
