How many watts?Īs a basic rule, match 200-250 watts of any solar type, for each 100 Ah of your lithium battery bank. This should allow charging from nearly empty to full in one full day of direct sunlight. The good news is, by following a few basic rules, you can figure out how many watts you need for properly charging your Battle Born Batteries. Should you go with Monocrystalline (MPPT), Polycristalline (PWM), thin film, or amorphous? Do you need 12 V panels, 24, 48, or maybe even 72 volts? Implementing a solar system can be confusing to say the least, panels come in a wide array of shapes, sizes, wattage, voltages and types. 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.
