Ventus Battery EVO GT 72V 50Ah (Surron Light Bee)

Surron Light Bee EVO GT: Battery Upgrade for Surron Light Bee

Model: VTB7250-9C-QF

Capacity: 50Ah

Voltage: 72V

Quick Charging Time: 1h

Max Charging Current: 50A (1C) with the support of VTB fast charger (XT90)

Driving Range: 165 km (laboratory result measured at the average speed of 25 km/h)

Battery Pack: Grade A 21700 Cells (Samsung 50S, volts difference less than 0.01V after 10,000Ah cycles)

Battery Cell Lifespan: Minimum 70% of capacity after 3 years

Standard Power: 19.2 kW/ 250A

Peak Power: 32kW/250A Peak (550A peak BMS for 10 seconds set to 400A peak for this battery)

Voltage Drop: Battery voltage drops 7V at 250A

More Effective BMS: A 22-pcs HYG017N10 MOSFET BMS enables 10 seconds of 550A peak discharge while limits heat generation under 18W at 250A discharge. Custom design of BMS maintains great stability under high-current pulse and protects the MOS from the risk of short circuits.

BMS Protection: BMS protection system blocks 12 battery damages during charging and discharging. Its real time condition shows both in the App on your devices through bluetooth connection and on color LCD.

Waterproof: IP67 rating (battery discharge cells sealed with Epoxy Resin provide a comprehensive water-proof level of outdoor riding)
Connectors: Two updated RAS 6808 connectors allow continuous current at 240A and peak current at 480A, replacing the Sur-Ron REB6808 200A connector.

Spark Prevention: The battery is designed with a holding-down power button to substitute the breaker (air circuit)/ air switch to avoid arc or spark.

VTB Interactive Color LCD: The color display shows real time data such as SOC, Volts, Amps, Power and temp from BMS feedback. Easier for riders to locate problems when the battery shuts down. Accidental touch protection turns on whenever it is over 0A current on the screen surface to avoid unintentional turn-off.

Mini Charging Port: The built-in XT90 port is extra thin so charging can happen while the battery sits in the bike, but it allows ultra fast input at 50A continuously. The rubber cap of the port provides full coverage for waterproofing.

Specifications

Weight: 18.2 kg

Dimensions: 154x138x385mm

Restrained Heights: The battery fits into the original battery tank, pushing up only 2 cm

Tabs Material: Traditional nickel tabs are upgraded to CNC (Copper-Nickel-Chrome), improving the discharging efficiency by restricting its resistance to 0.1mΩ.
