Lithium Battery Isolation Manager Li-BIM 225A

The Lithium Battery Isolation Manager (Li-BIM) isolates the two battery systems, Chassis and Coach in a motorhome, or Start and House in a power boat, systems with long running periods of engines. This prevents loads in one system from discharging both. It also connects the two battery systems together during charging. Both batteries are charged if either is being charged. The Coach battery can be charged while driving in addition to the normal charging of the Chassis battery, and the Chassis battery can be charged if needed in addition to the normal charging of the Coach Battery while plugged into Shore Power. This device is perfect for RV charging applications, as well as in larger power boats.

Key Features:

1. Provides up to 225amp continuous power

2. Runs cooler using less power: draws no current in the ON or OFF state, and supports solar charging of the Chassis(Start) battery.

3. Microprocessor based: Monitors battery state over longer periods of time, not simply voltage dependent

4. Approved for battery compartments (ignition proof), waterproof, and salt spray rated

5. Charges Lithium Coach/House battery from Alternator, and lead acid Chassis/Start Battery from the Coach/House Chargers

6. Isolates Batteries to prevent discharging or overcharging of Batteries

7. Prevents equalization charges from damaging Chassis/Start battery; annoying clicking of older isolator designs; Overcharging of the Coach/House Battery during long trips; and, Overcharging of Chassis/Start Battery during long connections to shore power.

8. Provides Emergency Start with Dash Switch. Optional power connection for existing applications, and ground connection to allow Emergency start from either battery.

9. Weighs under 1 pound

The Li-BIM monitors the battery voltage of both the Lead Acid Chassis/Start and Lithium Coach/House batteries over long periods of time. If it senses a charging voltage, it connects the two batteries together. If the charging system is drastically overburdened, the batteries will be isolated, however, if the Li-BIM sees a long term charging of both batteries it will allow the batteries to remain connected and allow the charging system to do its job. Once the batteries have charged for one hour, the Li-BIM will isolate the batteries to prevent overcharging, and will only reconnect the batteries for charging if one of the batteries drops to approximately 80% charge, and the other is being charged. This long term monitoring of the batteries prevents the annoying relay clicking that exists in simpler isolation modules today. The Li-BIM does not guarantee 100% battery charge, but prevents harmful battery charge levels.
