ASI BAC855 Controller Kit for INOKIM OXO – Plug and Play Upgrade

The ASI BAC855 controller kit is a pair of field-oriented control (FOC) motor controllers built specifically for the INOKIM OXO dual-motor electric scooter. Both units replace the original OXO controllers located in the scooter deck. Phase current reaches 2 × 106 A, and output ranges from 3000 W to 15,000 W depending on your battery.

Every connector matches the factory INOKIM OXO wiring. Therefore you never touch a soldering iron. You open the deck, lift out the stock controllers, and drop the new pair into place. Each controller measures 81 × 55 × 39 mm and weighs 300 g, so both fit the original mounting space.

This kit took more than three years of development and testing. The result is a stable, precisely tuned package for one scooter model only. Because the controllers pair with the colour display, you adjust power straight from the handlebar.

Key Benefits

• Plug and play installation – all connectors match the factory OXO harness, so no soldering or rewiring is needed.
• 2 × 106 A phase current – both motors receive far more current than the original controllers allow.
• Four power configurations – 3000 W, 4100 W, 12,500 W or 15,000 W, selected according to your battery.
• Display-based power control – change the power level directly from the screen without connecting a computer.
• Assist level in percent – tune assistance in percentage steps to match your riding style.
• Wheel size setting – enter your wheel size for accurate speed readings on the display.
• Motor overheat protection – the system monitors motor temperature and reduces power when needed.
• Battery wear protection – power drops automatically once the charge level runs low.
• Remote programming session – every buyer receives a private remote session with our engineer.

Who Is This Kit For

This kit fits the INOKIM OXO dual-motor electric scooter and nothing else. Both ASI BAC855 units replace the original OXO controllers mounted underneath the deck. We do not prepare this set for other scooter models.

It suits riders who want more power and torque from the standard OXO motors. In addition, it fits owners planning a move to a custom 60 V or 72 V battery pack. With a 72 V pack, top speed climbs to roughly 137 km/h. That figure was measured with a 67 kg rider on modified motors.

Before ordering, tell us which battery you run. Your answer determines how we configure the controllers. To use the full potential of the ASI BAC855, the battery must deliver at least 160 A.

Battery Options and Configuration

• Option 1 – stock 60 V 25.6 Ah pack – controllers set to 2 × 106 A and 1500 W each, giving 3000 W.
• Option 2 – stock 60 V 25.6 Ah pack with BMS bypass – controllers set to 2 × 106 A and 2100 W each, giving 4100 W. This setup can over-discharge the pack, so it carries risk.
• Option 3 – custom 60 V pack rated 160 A – controllers set to 2 × 106 A and 6250 W each, giving 12,500 W.
• Option 4 – custom 72 V pack rated 160 A – controllers set to 2 × 106 A and 7500 W each, giving 15,000 W.

What’s in the Box

• Two ASI BAC855 controllers, prepared for INOKIM OXO connectors.
• Software configuration completed in advance for the battery you specify.
• A remote programming session with an engineer, plus an installation check.
• An aluminium motor heatsink in orange or black is available separately.

Technical Specifications

Why Choose This Kit

Most controller swaps demand cut wires, new plugs and hours of bench work. This set arrives with OXO connectors already fitted and software already loaded. As a result, the job becomes a deck-open, swap and close procedure.

Three years of tuning went into one scooter model rather than a generic fit. Consequently, throttle response and current delivery stay consistent across the whole power band. The motor temperature monitor and low-charge power reduction work in the background during hard riding.

Support does not stop at delivery either. Each buyer gets a private remote session where our engineer verifies the installation and adjusts settings. You can then fine-tune assist percentage and wheel size yourself through the display.

Frequently Asked Questions

Does the ASI BAC855 kit fit any scooter other than the INOKIM OXO?

• No. We prepare this set only for the INOKIM OXO dual-motor scooter.
• Connectors and software are matched to that model alone.

Do I need to solder anything during installation on my INOKIM OXO?

• No soldering and no rewiring are required.
• Open the deck, remove the stock controllers and fit the new pair.

How much power will I get with the original battery?

• With the stock 60 V 25.6 Ah pack, the kit runs 3000 W total.
• With a BMS bypass, output rises to 4100 W, though over-discharge becomes a risk.

What battery do I need for the full 15,000 W?

• A custom 72 V pack able to deliver 160 A.
• Each controller is then set to 7500 W at 2 × 106 A phase current.

Which displays work with these controllers?

• The 750C display and the Eggrider V2 are both supported.
• Power level, assist percentage and wheel size are set through the screen.

How fast can the scooter go?

• Around 137 km/h with a 72 V pack and modified motors.
• That figure was recorded with a 67 kg rider.

What information do you need before shipping?

• Tell us which battery you run on the scooter.
• We then configure both controllers to the matching power option.

Are the motors protected at high power?

• Yes. The system tracks motor temperature and cuts power when it climbs too high.
• Power also drops automatically at low battery charge.

Choose your battery option, share the details with us, and we ship both controllers configured and ready. Installation takes one deck opening, and the remote session with our engineer confirms everything runs correctly before your first ride.
