Battery Issolation Manager for Lithium Batteries
Part Number: Li-BIM225
Availability: Ships in 1-2 business days.

When adding lithium to an existing or new installation it is important to understand how your house and coach battery banks will interact with each other and with your engine alternator. It is also important to ensure your RV's alternator does not overcharge your lithium battery bank which is much more efficient than a traditional AGM or Lead acid battery. The Li-BIM 225 Battery Isolation manager is designed to ensure all of these functions are handled automatically and is a drop in replacement for 95% of existing battery isolation managers that come pre-installed on most rv's with an engine alternator. 

Under normal charging conditions, the BIM will connect for 15 minutes every 35 minutes. That means that the BIM will connect for 15 minutes, disconnect for 20 minutes, and repeat this cycle until the house battery bank is charged. This also prevents over charging. 

If the house battery resting voltage exceeds 13.4V than the BIM will disconnect. A resting voltage greater than 13.4V indicates a fully charged battery. Note that “resting voltage” means that no current is flowing to the coach battery.

The BIM will disconnect if the alternator voltage exceeds 14.4V. This protects the house battery from over charging.

The BIM will disconnect if the voltage difference between the alternator and the coach battery is less than 0.1V. If the voltage difference is too low, then there is a negligible charging current, and no need to connect to the coach battery

The BIM will disconnect if the alternator voltage drops below 13.3V. If the alternator voltage is too low, than it cannot adequately charge the coach battery, so there is no reason to connect.
