WFCO WF-8955-AD-MBA Main Board Assembly 55 Amp — Auto Detect — Replaces WF-8955 Series

WFCO WF-8955-AD-MBA Main Board Assembly — 55 Amp — Auto Detect — Replaces WF-8955 Series

Direct replacement main board assembly for WFCO WF-8955 series 55-amp power centers. Patented Auto Detect technology automatically charges lithium-ion and lead-acid batteries. Installs in ~10 minutes with 2 screws, 3 AC wires, 2 DC wires — no rewiring required. 950W output. 2-year warranty.

⚡ The WFCO Auto Detect Advantage — Patented Technology

The WF-8955-AD-MBA Main Board Assembly includes the exclusive, patented Auto Detect technology. This microprocessor-driven technology will recognize lithium-ion and lead-acid battery chemistries and automatically adjust the charging profile to match the battery type.

No more buttons. No more switches. An accurately charged battery gives RV owners peace of mind. Eliminating the risk of over- and under-charging, the WF-8955-AD-MBA will maximize your battery life with multi-stage charging and current monitoring in both lead-acid and lithium-ion profiles.

The WF-8955-AD-MBA has optimized charging for battery chemistry built in:

  • Lead-Acid Batteries: WFCO's automatic three-stage converter handles every charging need for the RV while extending the battery's life
  • Lithium-Ion Batteries: The multi-stage process ensures a safe operating voltage for all loads, replaces energy in the battery, and assures the lithium-ion cells inside the battery remain balanced

~10-Minute Board Replacement — Upgrade Your WF-8955 Series to Auto Detect

The WFCO WF-8955-AD-MBA is a direct drop-in replacement for the lower power converter section of any WF-8955 series power center. It upgrades your existing unit to Auto Detect technology without replacing the entire power center — and without rewiring. Installation requires only two screws, three AC wires, and two DC wires, and takes approximately 10 minutes.

55 amps of output power with 950W capacity, three-stage charging for lead-acid batteries, and the full Auto Detect lithium-ion profile — all in a board that installs in the same footprint as the original. Standard safety features include over-current, over-temperature, over-voltage, and reverse polarity protection.
