- Detects the battery type and picks the profile itself
- Chemistries recognised
- Lead-acid, AGM and lithium
- Lead acid stages
- Three stages for lead-acid and AGM, two for lithium

- Lithium bulk runs one to four hours
- Lithium bulk voltage
- 14.6 V bulk once it has detected lithium
“With this new technology, the power converter will evaluate the charging cycle of a battery, determine the type of battery being used, and then choose the appropriate charging program(profile) to provide for the best performance and maintenance of that battery.”

“Because of the differences of Lead Acid, AGM and Lithium type batteries, a system that provides a charge to the battery or batteries must be able to accommodate the different charging requirements.”

“On the other hand, Lithium batteries will prefer the use of only two stages when charging, and therefore the power converter will charge using the WFCO Two-Stage Smart Charging system.”

“For a full battery, the bulk stage has a minimum time requirement of one hour, which allows the lithium cells inside the battery the time required to “balance”. For an empty battery, the bulk stage has a maximum time requirement of four hours.”

“This is accomplished by boosting the output voltage to 14.6 VDC and allowing the maximum current to flow as required by the loads.”

Compatible batteries
These batteries are here because the published figures line up, not because anyone has said they go together — that is our reading of two documents that never mention each other, not a claim by either maker and not a test by us. Even where every figure agrees, these are not established:
- Which charge profile the charger is actually set to — several publish four or more, and only one of them is this pack’s chemistry
- What it holds the pack at once bulk charging ends, which is a different figure from the one it boosts to, and which some profiles do not apply at all
- The charge current the pack will accept, against what the charger delivers into it
- Whether the charger can restart a pack its own BMS has already disconnected
- The wiring in between — where a converter feeds a distribution panel, the pack is one load on a circuit rather than a device on the end of a lead
Worth confirming with the charger's manufacturer or a dealer before buying.
Renogy state this pack's charge voltage as 14.4 V — their datasheet reads "Charge Voltage 14.4V". This converter decides for itself: WFCO's manual says it will "evaluate the charging cycle of a battery, determine the type of battery being used, and then choose the appropriate charging program(profile)", recognising lead-acid, AGM and lithium. Once it has settled on lithium it charges in two stages and reaches 14.6 VDC in bulk, at or above the figure this pack asks for. The condition matters and is theirs, not ours: the 14.6 V depends on the converter detecting lithium. Neither company names the other, and nobody has tested this pairing.
Redodo state this pack's charge voltage as 14.4 ± 0.2 V — their datasheet reads "Charge Voltage: 14.4V±0.2V". This converter decides for itself: WFCO's manual says it will "evaluate the charging cycle of a battery, determine the type of battery being used, and then choose the appropriate charging program(profile)", recognising lead-acid, AGM and lithium.

Vehicles the manufacturer names for this charger
- Forest River Prime Time AvengerManufacturer documentedView platform: Forest River Prime Time Avenger →
Forest River publish this converter's manual in the 2026 Avenger's own Electrical component list. They list THREE converters for the model — the WF-8700-AD, the WF-9500-AD and the WF-9500LiS — and do not say which floorplan or option package carries which, so this names what the maker documents for the model and not what is in any particular trailer. Read the part number off the front panel label of your own unit.
