For those who tow caravans, camper-trailers or camper-vans, Projectaís new BM320 Battery Meter is ideal. The BM320 Smart Battery Meter is suited for use with 12V Wet, AGM, Calciumtype and Gel batteries up to 320amp/h in capacity. The battery data is easy to see thanks to the unitís full-colour 2.4-inch LCD interface that actually includes two screens. Screen one is for the beginner user and includes all information needed to check battery performance (voltage, charge/discharge, capacity remaining and time to empty/full), while the second screen provides additional info such as ambient temperature, battery capacity reading (ampere hour) and state-of-health (SOH). There are two inbuilt alarms (low capacity and SOH) and a real-time clock with date and battery status display. The unit is superaccurate and also boasts self-learning capabilities to track and monitor battery SOH.
