  1. Under normal conditions, all the energy should be discharged when you reach 40V. However, during short high current discharges, the battery voltage can momentarily drop below 40V. Therefore set the low voltage disconnect as low as possible.


Make sure to lower the Dynamic Cut-off parameters, to 37.5, 37.4, 37.3 and 37.2.
