Description

The BCM-5P series are an evolution of our popular LED battery condition meters. Battery technology is improving all the time and new battery types are available with characteristics that are very different to lead acid ones. For some of these, particularly lithium based batteries, it is vital that they are not discharged below a certain voltage otherwise permanent [& expensive] damage may occur. Also lithium batteries have a much flatter discharge curve, this means that there is only a small voltage difference between 80% full and 20% which makes it tricky to measure capacity accurately.

The BCM-5Ps use an accurate reference voltage, a temperature sensor, and an Atmel microprocessor to make precise voltage measurements, compare them to known discharge curves, and then indicate the capacity accordingly.

The main features of the BCM-5P series are;

• Very accurate [+/- 0.1V]
• Built-in temperature compensation [depends on model]
• Low voltage cut-off function to protect valuable batteries  [can interface to most of our controllers]
• Will fit existing 5 LED BCM installations
• Versions for 12V, 24V, lithium, and lead acid

For volume orders we can modify the software for different voltage curves or cut-off points for almost any battery chemistry between 11V and 30V
