Replaced a controller that got damaged during works accidentally from touching wires. Great replacement. Noticed a bit of extra power, too.
52V 25A Controller suit VDM-10 / T10-DDM (e.g. Dragon Raptor)
Product Details
Brand: VDM-10 and T10-DDM by eScootNow
- Controller suits 52V dual drive models such:
- VDM-10 including
- Dragon Raptor and Raptor Pro.
- Apollo Ghost.
- Bolzzen Gladiator 52V model and the former model, Dynamo. 60V use systems use Zero 60V 10X 30A controller.
- Carbon Oxy.
- Glide MACH 10/10R.
- T10-DDM including:
- Zero 10X 52V models.
- Dragon Hunter X10.
- and Bexley and Black Edition variants.
- VDM-10 including
- Makes/models using this system are easily identified by having a QS-S4 display throttle typically accompanied optional keylock or have NFC display/throttle.
- Optional B-Rear Keylock Stub: The B-Rear controller has a 3-pin connector with wire colours red, orange, black to connect to a keylock. If your scooter does not have a keylock, you will need a B-Rear Keylock shown below which is a red loop wire (stub) that bypasses the keylock circuit. It bridges the 3-pin connector red and orange so that power is applied to display/throttle for it to do the power-ON switching. Your existing non-keylock controller may already have this stub - check yours. Image below shows the 3-pin connector on controller with the stub fitted.
- 52 volts (V), 25 amps (A) current = 1300 watts (w) at 52V or 1450w at 58V (per controller).
- Low voltage cut-off at 42V.
- Sine Wave (has hall sensor wires).
- Motor power wires have yellow MT60 3-pin connector. Alternatively you can fit Bullet Connectors if retrofitting to a non-MT60 motor wire.
- Each controller is 115mm x 55mm x 33mm.
- Kyesang branded. Supplied as Titan Factory spare from factory that produces controllers for these model scooters as shown in production with FalconPEV.
- Typically required as replacement when display presents controller failure error 9 (E9) or motor runs rough (like combustion engine missing a cylinder).
- Order both A and B controller for both front and rear. It is worthwhile ordering A+B together as set/pair if renewing due to water ingress.
Notes:
- Reference for wiring diagrams.
- Be mindful of heat dissipation.
- Controllers are designed for dual motor operation. It is recommended to maintain dual drive at all times to "share the workload" across the entire system.
- The low voltage cut-off defines the voltage at which the controller will "cut off" and no longer draw any power from the battery pack to prevent excessive discharge. The value is represented on the controller nameplate. For example with a 48V system, the product is factory configured to 37 volts, this is fixed and cannot be user-defined. If voltage drops to this level, the controller will turn off (shut down). This will typically occur under heavy throttle at low battery level (watch the voltage reading on the display when riding). It is one of the several methods of low voltage protection. Battery Management System (BMS) low voltage protection, which is a secondary protection, works in similar manner though self-resettable fuse in the BMS kicks in to power off the scooter, the scooter cannot be powered on until charger is connected. The BMS Low Voltage Cut-Off is typically marked on the battery pack nameplate. The third mechanism to protect from undervoltage is the P setting (throttle/display user manual), P1: "Undervoltage", this value can be user-set in 0.5v increments. The P1 setting provides a "graceful" implementation by reducing throttle (effectively mode/gear 1, or a "limp" mode) when the threshold is reached to protect excessive low voltage on the battery chemistry. For 48V (see the reference graph) systems with high endurance cells, eSN recommends this be set to 42 volts as the 37V current limit on the controller is pretty low. You can watch your voltage drop when throttling heavy on low battery. High output packs such as those on the GTR v2 controllers when paired with high demand battery packs will drop less voltage than the same controller on high endurance packs.
- Naming convention A (Front) and B (Rear). This convention is adopted by Zero and Jinpin controllers as used on Dragon GTR/S Series, Cyclone and Predator, whereas the opposite A/B convention is used by Kaabo where A denotes the Rear Master. In all instances, the display/throttle and the bulk of the other other cables connect to the Rear controller. The front controller is is the secondary or slave, Kaabo refer to the front as Deputy, Unicool simply adopt designation type A.
- Intended to operate with QS-S4, VSETT or Copy NFC display/throttle or VSETT Advanced Central Display.
