POWER CENTERS: WF-8540-AD Power Center

Product Description

WF-8540-AD Power Center

With future RV development in mind, WFCO has developed the WF-8540-AD Power Center, an advancement to the most forward-thinking power center available today that includes an industry-first, Auto-Detect technology. This new 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-8540-AD Power Center will maximize your battery life with multi-stage charging and current monitoring in both lead-acid and lithium-ion profiles.
