Reference Materials for TurboCharge

This page contains trusted resources from the masterclass spare parts specialist relating to TurboCharge products and charging references of note relating to electric scooter charging systems such as those from NAMI, Teverun (and Dualtron) and Kaabo and next level TurboCharge Super Fast high-current charging connectors.

GX16 3-pin

The common GX16 3-pin standard adopts Male 1+ve, 3-ve (2 empty). Some rare models adopt pin 2 for the -ve. Reference our GX16 Charging Ports page for further info.

Dragon / Langfeite

For the latest generation Dragon/Langfeite models, a charger with YJ20 male connector is required. It has 4 pins, allocated amongst the four different voltages.

• 54.6V 2.0A charger (for 48v models of GTS/GTR including V2 & Ninja): Pin 2 (Positive), Pin 3 (Negative).
• 58.8V 2.0A charger (for 52V models of Cyclone series): Pin 2 (Positive), Pin 4 (Negative).
• 67.2V 1.75A charger (for 60V models of Predator, Lightning V2 & Beast): Pin 1 (Positive), Pin 2 (Negative).
• 84V 4A charger (for 72V Hurricane): Pin 1 (Positive), Pin 3 (Negative).

The intention is for different pins to be used across different voltage systems to prevent inappropriate voltage being applied.

54.6V for 48V > 58.8V for 52V >
67.2V for 60V > 84V for 72V >

Note: Bike Scooter City (the Dragon brand owner) use diagrams like these on both the charger and charging ports products on website. The diagrams on charging ports are incorrect (they show the face of the plug, not the charging port on eScooter).

NAMI Reverse GX16 2-pin

Detailed images of the designation markings are on the NAMI Charging Port product page.

Teverun / Dualtron charging port (BM)

Chargers feature BM (Baming) connector 3-Pin male 1+ve, 3-ve (2 empty).
As tested on Teverun Fighter Supreme ULTRA and reflective of all Teverun / Dualtron models that have connector of this visual appearance.

Kaabo charging port (LT)

Chargers feature "LT" connector 3-Pin male 1+ve, 2-ve, (3 empty).
As observed on eSN stocked Kaabo charging port spare part, noting the marking on the rear of the port and reflective of all Kaabo models that have connector of this visual appearance.

Note: 3rd pin blanked on battery of Wolf GTR was observed in post by Mike McQueen November 2025. The original charger Kaabo branded AP-PN180CH08400020 (84V 2.0A) is without the 3rd pin. It is assumed the pin can be removed. De-pinning should be straight forward as that 3rd pin is not connected.

VSETT / MUKUTA / Ausom / (likely Zero) and Kugoo are understood use a different connector which has a quarter-turn lock as shown below on Ausom DT 2 Pro (52V).

eSN TurboCharge Conversion Cables

TurboCharge conversion cables enable chargers fitted with the conventional GX16 3-pin female plug to be used on the more modern non-exposed connectors such as those above (and reverse GX-16 2-pin as adopted on NAMI models).

All cables are fabricated to eSN custom specification and feature heavy gauge wire similar to that of TurboCharge extension cables. These cables allow existing, or more commonly available chargers to be used including those that are 3rd party. Image below shows concept . Stocks expected Q4 2025. We presently have stocks of GX16 3-pin Male 1+ve, 2 empty, 3-ve to 1+ve, 2+ve, 3 empty which are required for a small number of makes/models such as eMove Cruiser as shown below adjacent to the TurboCharge Fast YZ500.

Fine tuning voltage output.

Did you know the precise voltage for chargers can be fine tuned (calibration) as shown by Finiphile. A great option for non-common voltages such as 57.6 volt Inokim Ox, where a 67.2v charger could be adopted for 57.6v system.

eSN TurboCharge Super Fast Charge Connectors (20 Amp YA-20-2).

For release as part of mission eSN2026#JP-CN, March 2026. Supports single-connector charging to 20 amps, typically coupled with our industrial MC900 and MC1200 desktop chargers as shown below. A suite of cables, conversion cables, panel mount charger port for eScooter and internal wiring harnesses are included in the line-up.

Images below show the inaugural samples that featured the YA-20 cable hard wired. Production version adopts newer, more appropriate YM-20 which is the quarter turn and with cap rather than hinged metal cover. Shown below MC900 (10 amps) is black, MC1400 (14 amps) is orange. Field tested March 2025 on eScootNow - The Facebook Group.
