Suits owners needing a direct HAC-038 swap.

This cell suits owners of the Home Circuit Mario Kart Live kit who need a fresh power pack matching the original specifications. Buyers with different RC toys, drones or handheld consoles should look elsewhere because the connector and form factor are specific to this model. The 1750mAh minimum capacity and 6.48Wh rating match the factory cell.

Critical spec: HAC-038 part-number match

The single specification that decides fitment is the battery part number HAC-038. Confirm this code on your original pack before ordering; a different number means the connector or dimensions will not align. The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for safety compliance.

Questions about this item

What does the 1800 mAh rating mean for actual play time in the Home Circuit Mario Kart Live kart?

The 1800 mAh capacity matches the original HAC-038 spec and typically delivers around 90 minutes of continuous racing before the kart needs recharging.

How does the 3.7 V lithium cell connect to the kart and what limits the charge rate?

The pack uses the same two-pin JST-style connector as the factory battery and relies on the kart’s own charge controller to manage current and voltage limits.

Will the 69.8 x 38.6 x 6.5 mm pack fit the battery compartment without modification?

Yes, those dimensions are identical to the original HAC-038 cell, so it slides into the Home Circuit kart’s battery bay and secures with the existing latch.
