Direct replacement main board assembly for WFCO WF-8935 series 35-amp power centers. Patented Auto Detect technology automatically charges lithium-ion and lead-acid batteries. Installs in ~10 minutes — 2 screws, 3 AC wires, 2 DC wires, no rewiring required. 600W output. 2-year warranty.
The WF-8935-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-8935-AD-MBA will maximize your battery life with multi-stage charging and current monitoring in both lead-acid and lithium-ion profiles.
The WF-8935-AD-MBA has optimized charging for battery chemistry built in:
The WFCO WF-8935-AD-MBA is a direct drop-in replacement for the lower power converter section of any WF-8935 series power center, upgrading it to Auto Detect technology without replacing the entire unit and without rewiring. Two screws, three AC wire connections, and two DC wire connections are all that's required — installation takes approximately 10 minutes.
35 amps and 600 watts of output power, three-stage charging for lead-acid batteries, and the full Auto Detect lithium-ion profile — all in the same compact board footprint as other WF-8900 series replacement boards. Standard safety protection suite included. Backed by a 2-year limited warranty.
