The MegaloDONGLE Activator Powerstrip is designed especially for your DIY Powerwall build using ES200G 40-Cell Scooter Packs. Connect multiple MegaloDONGLE Activator Powerstrips together to build your powerwall to your custom specs. Each MegaloDONGLE Activator Powerstrip allows you to activate/wake 10 Okai ES200G Scooter battery packs. Discharge via an SB120 Anderson connector, charge via XT90. 

DIGITAL UNLOCK SIGNAL

The MegaloDONGLE Activator Powerstrip sends the required Digital Unlock Signal each battery pack needs in order to remain ON while in use.

CHARGING + DISCHARGING CABLES

Each MegaloDONGLE Activator Powerstrip needs 10x male scooter pack charge cables and 10x male scooter pack discharge cables to take full advantage of the scooter pack's BMS safety features.

BUILT-IN METER w WIRELESS

The MegaloDONGLE Master supports a DC 500V 500A WIRELESS VOLTAGE/POWER/CAPACITY METER. It has 18 functions to help you conveniently and quickly access more accurate measurements. Note: Slave MegaloDONGLE  do not require a meter.

Wireless transmission of data, to avoid the complex wiring between the display and detection modules that could cause interference.

Hall sensor is used to realize non-contact detection current without disconnecting wires, which is safe, reliable and convenient.

Voltage, current, power, temperature, capacity, percentage of remaining capacity, running time is displayed at the same time.

Double relay interface. Manage charge and discharge separately.

With charge over voltage, discharge under voltage, charge over-current, discharge over-current protection.

The memory function of the breakpoint, power-on and power-off, and the number of AH and WH before power-off can be memorized.
