ISAscale 300 High Precision CAN Shunt
This CAN device measures up to 3 battery pack voltage segments, with full isolation, on packs up to 800v, and is rated for 300 Amp current measurement. You can run up to 2000 amps for up to 10seconds. Best of all, it reports these three voltages and this highly accurate 0.1% current measurement using standard CAN messages. But wait, there's more. Temperature. Ampere-Hours are accumulated. kWh are accumulated. All available by CAN. This one device essentially IS a Battery Monitoring System.
