The BMS allows you to control the heating of the pack until it reaches the positive temperature necessary to turn on the charging<\/p>\n<p>The BMS output can control the mat directly (max. current 3A) or with a relay at higher currents.<\/p>\n<p><strong>The BMS JK is a fully customizable device. This means that it can be used to support Li-Ion, Li-FePO4, LTO cell packages. It is designed to work with different number of cells  <\/strong>(to the extent described for a particular BMS).<\/p>\n<p>BMS JK have a built-in <strong>high-current active balancer<\/strong> and a Bluetooth module for communication with a mobile app (Android, iOS).<\/p>\n<p><strong>The device needs to be configured in the mobile app for proper operation.
