WF 8955 MBA RV Power Converter 55Amp 3-Stage Charging for Sealed/Lithium Batteries Overload, RV & Camping Upgrade Compatible with RV Trailer Power Systems 12V 13.6V — Open-Box, 25% Off

Suitable for: Replacement parts WF 8955 AD MBA and WF 8955 MBA with this power converter. This is a smart power converter specifically designed for motorhomes, a highly professional upgrade or replacement component for the core electrical system of a motorhome/RV. Voltage Conversion: This power converter converts input 110V or 120V AC power to a stable 12V DC power, supplying power to various low-voltage electrical and electronic systems in the motorhome, such as lighting fixtures, car audio systems, water pumps, air compressors, etc., ensuring their proper functioning. Three-Stage Smart Charging: The power converter features a 13.6V three-stage smart charging function, automatically switching between batch charging, absorption charging, and float charging modes based on the battery's status. In batch mode, the battery is quickly charged at a higher voltage (e.g., 14.4V); in absorption mode, the voltage drops to 13.6V to ensure a full charge; and in float mode, a lower voltage (e.g., 13.2V) trickle charges the battery to maintain its charge and extend its lifespan. Automatic Battery Type Identification: The power converter can automatically detect the type of battery connected, whether it's lead-acid (including standard lead-acid and AGM batteries) or lithium-ion batteries. It can automatically adjust the charging mode and parameters to provide optimal charging results for different battery types, eliminating the risks of overcharging and undercharging. Multiple Safety Protections: The power converter also features multiple safety protection functions, such as overvoltage protection, overcurrent protection, overload protection, overheat protection, short circuit protection, and reverse polarity protection. These effectively prevent damage to the power converter and connected devices due to electrical faults, ensuring safe and reliable use. 1. OE NUMBER: RV converter replace part number are WF 8955 AD MBA, WF 8955 MBA. Please check the part numbers whether it suits your vehicle before purchasing.
2. ENHANCED SECURITY: Equipped with over current guard, over temperature guard, over voltage guard, and reverse polarity guard. Cooling fan runs when needed not at start.
3. VERSATILE UPGRADE: Electronic current limiting shuts down power during overload or short circuit conditions. Compatible with a variety of RV trailer camping vehicle power systems.
4. ADAPTIVE CHARGING PROFILE: Automatically adjusts charging profile to match sealed or lithium ion battery type. Maximizes battery life with multi stage charging and current monitoring.
5. DUAL BATTERY MODE: Switch between sealed and lithium cell. LED indicators show battery type selection. Offers precise charging without over or undercharging risks.

Spec:
Item Type: RV Power Converter
Material: Metal, ABS
Input Voltage: 12V
OE: WF 8955 AD MBA, WF 8955 MBA
Output Voltage: 105-130 VAC 60 Hz
Current: 55Amp
3 Stage Charging: Bulk Charging: 14.4V, Normal Charging: 13.6V, Float Charging: 13.2V
Features:
Sealed Mode: Switchable between sealed and lithium cell, automatic recognition. In sealed mode, the switch is on with an orange LED labeled 'LA' on the right side. The converter operates in bulk mode at 13.6 VDC. When the reversed polarity is pulled out, the LED status remains unchanged, with only the DC output interrupted.
Lithium Mode: When the switch is set to lithium ion mode, an orange LED labeled 'LI' lights up on the left side while the orange LED on the right side goes out. The converter voltage is 14.6 VDC in this mode. If the reversed polarity is removed in this mode, the orange LED (LI) will go out and the DC output will be interrupted. Please note that this is different from sealed mode.
