If the voltages were within this scenario’s parameters, the response would repeat. The Li-BIM 225 would connect the batteries for 1 hour, then disconnect the batteries for a wait time of 2 minutes.Īfter this wait time, a new voltage reading would be taken of each battery. BIM Scenario 2Īnother scenario a BIM would be used in would be if the chassis battery voltage was below 12.5 V and the coach battery voltage was greater than 13.5 V. If the voltages remain within the scenario’s parameters, the response would repeat. After this duty cycle, a new voltage reading would be taken of each battery. In response, the Li-BIM 225 would connect the batteries for 15 minutes, then disconnect the batteries for 20 minutes. One of the scenarios a BIM would be used in would be if the engine was “on” with a chassis battery with a voltage greater than 13.4 V and the coach battery had a voltage less than 13.3 V.

The BIM can monitor and regulate the voltages of your batteries in a variety of ways. We recommend incorporating a BIM into your system when you want to charge your auxiliary batteries from your alternator. The Li-BIM 225 can monitor the voltages of your chassis and coach or auxiliary batteries. If the alternator voltage is too low, than it cannot adequately charge the coach battery, so there is no reason to connect. The BIM will disconnect if the alternator voltage drops below 13.3 V. 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 voltage difference between the alternator and the coach battery is less than 0.1 V. This protects the coach battery from over charging. The BIM will disconnect if the alternator voltage exceeds 14.4 V. Note that “resting voltage” means that no current is flowing to the coach battery. A resting voltage greater than 13.4 V indicates a fully charged battery. If the coach battery resting voltage exceeds 13.4 V, then the BIM will disconnect. That means that the BIM will connect for 15 minutes, disconnect for 20 minutes, and repeat this cycle until the coach battery is charged. The BIM will connect for 15 minutes every 35 minutes. For smaller battery banks, this could lead to overcharging, which could potentially shorten the cycle life of the batteries. The BIM is designed to allow up to 225 amps of current to the batteries during a charge cycle. Whether it’s in a motorized, towable, or truck camper, Battle Born has the batteries, components and knowledge for your lithium upgrade.Ī Battery Isolation Manager (BIM) is essential for alternator charging in 12 V systems only.īattle Born recommends using the BIM in systems with 3 or more batteries. Our experience enables us to assess your current batteries and components and allows us to build a system to power your future adventures. Brands like Victron Energy, Progressive Dynamics, Sterling Power, Micro Air and many more make products that excel in a lithium power system.

We’ve performed extensive testing on the RV industries major suppliers to ensure compatibility. We work with a network of installers that can help make this transition as easy as possible.

They can also advise on the install of batteries and equipment. Our staff specializes in the technical specifics about lithium batteries and the components to support a lithium upgrade. Our batteries were designed as replacements for the most common lead acid sizes on the market, so you can find the 12 V or 24 V lithium deep cycle battery that works best for you. We build our batteries to perform better, last longer and provide the deliverable power needed for weekend adventures or full-time boondocking. At Battle Born Batteries, our goal is to power your ideal RV experience.
