Here’s a preview of our update to our BCM-524 battery meter. The old analogue model has been extremely popular and features in many designs. However battery technology marches on and we wanted something that would give more accurate results with lithium batteries and other types with flat discharge curves. We’ve used an ATtiny micro to produce a programmable replacement that can work with the small voltage changes these batteries give. Other features include temperature compensation, and a switchable output that can be used for a low voltage cut-off. Oh, and it still has the same hole spacings so it’s a direct physical replacement in most applications.
The first model will be suitable for 12V – 24V, we’ll produce some standard voltage curves for the common battery technologies, but if you want something custom please let us know.
