IMPORTANT TECHNICAL SERVICE BULLETIN

ISSUE

Potential Internal Battery BMS Damage

MODELS IMPACTED

2021 – 2022 Oliver Legacy Elite II models equipped with (3) Lithionics Lithium 130AH Batteries & Xantrex 3000W Inverter

INFORMATION

Oliver Travel Trailers was alerted that under certain conditions the Lithionics internal BMS could be damaged if the full load for inrush amperage to the inverter is loaded on a single battery.

RESOLUTION

Owners with impacted year models should follow the Lithionics approved method for the proper restart/reboot sequence of the batteries and inverter to ensure all batteries are ON before turning the inverter ON.

NOTE: The inverter is also a charger and when it powers up while connected to shore power this is utilizing the charger side. The above referenced potential condition exists only when the inverter side is turned ON.

PROPER RESTART/REBOOT SEQUENCE

If the inverter is OFF, drained or has entered (LBCO) Low Battery Cut Off and any or all of the batteries are OFF (no LED light on battery), then the following procedure should be followed:

1. ENSURE THAT THE INVERTER IS TURNED OFF

2. UNDER THE STREET SIDE BED ACCESS PANEL, SWITCH THE INVERTER CIRCUIT BREAKER TO THE OFF POSITION. PRESS THE RED BUTTON

Note: This will cause a communication issue for the inverter remote display and requires a proper restart sequence to ensure proper communication between the inverter and remote display. (Error 20)

3. TURN ALL BATTERIES ON
