► PRODUCT FEATURES
1.THREE STAGES CURRENT, TIMING & TEMPERATURE PROTECTION.
The unit has three stages of over current protection. Current based, length of time at over current levels and temperature based.
2.AUTOMATIC INTERNAL LOW VOLTAGE RE-START.
When the battery is stored for a long period with no charging lithium batteries normally are hard to recover. Our batteries have
Ultra Low Voltage Recovery, just connect the battery to lithium battery charger to auto recover easily.
3.SELF-RECOVERY AFTER A SHORT CIRCUIT.
The circuit trips when connected to the short-circuit source. The system automatically restores the power supply,
when the short-circuit source is disconnected.
4.PARALLEL CONNECTION OF THE BATTERY PACKS.
You can use an infinite amount of our batteries in parallel. Our BMS will handle this seamlessly.
5.ACTIVE CROSSOVER EQUALIZATION OF THE INTERNAL CELL BANKS.
Our multi string active cell balancer keeps the internal cells banks equalized, If one or more banks are lower than another bank
the balancer will divert power form the higher bank into the lower banks when charging and discharging.
6.BATTERY CAN CONTINUE TO OPERATE AFTER A SINGLE CELL FAILS.
When a single cell fails the battery pack will continue to operate normally but at a reduced capacity or power.
7.THERE IS NO VOLTAGE SPIKE, WHEN THERE IS A SINGLE CELL SHORT CIRCUIT.
When a single cell fails the Active Balancer will control the voltage of the other banks of cells so there is no voltage spike.
8.OUR BMS ADOPT DIGITAL CONTROL PROTECTION AND ANALOG CONTROL PROTECTION.
9.ON THE BASIS OF OVER-TEMPERATURED PROTECTION,OUR BMS HAVE THE FUNCTION OF LOW-TEMPERATURED PROTECTION.
