Note: 1. Each Each battery module has one slave BMS circuitry inside; 2. BMU act as master BMS circuitry collect all information from each battery modules through RS485, then decide to cut-off the contactor or not; 3. We We strongly recommend customer to use two contactors (one for charge and another for discharge) in the battery system. Our advantages  Battery module: 1. Modular design makes the system installation, maintenance easier; 2. Battery modules can be connected in series or parallel to make the system    more flexible; 3. IP56 dust and water proof design suit for in severe circumstance; 4. Dual LED indicator makes the battery module status easy to know; BMS: Besides the basic functions such as over charge/ discharge, over current, short circuit, over temperature and balancing, Our BMS owns the following features, 1. Master-Slave architecture makes the system flexible; 2. Two level warning makes maintenance easier; 3. CAN2.0 and industrial level electronic components make system reliable; 4. Contactor makes high rate charge & discharge feasible; 5. Periodic insulation measurement makes personnel safety possible; 6. Host can control the system easily;  BMU Photo Monitoring Software (Need USB-CAN Adapter)
