📖 Essential Charger Care & Battery Maintenance Guide

To maximize the overall lifecycle of both your high-output charger and your e-bike's lithium battery pack, please adhere strictly to these pro-rider protocols:

1. The Golden Connection Rule: Always plug the charger's output lead into your battery's charging port first, and then plug the AC power cord into the wall outlet. When a charging cycle is finished, disconnect the AC wall plug first before pulling the plug from the battery. Disconnecting the battery while a high current is flowing (indicated by a Red light) can risk internal arc damage over time.

2. The Saturation Top-Off: For the absolute best cell balancing, let the charger remain connected for an additional 2 to 3 hours after the LED indicator light transitions to Green. This allows the battery’s internal BMS to completely balance the cell groups.

3. Avoid Deep Discharge Dead Zones: Try not to run your e-bike battery completely down to 0% before plugging it in. Charging your battery before the low-voltage cutoff triggers will greatly extend the overall longevity of your cells.

4. The 3-Month Activation Cycle: If you routinely perform short, shallow rides, the internal chemistry can settle. Once every three months, run your battery down until the controller's undervoltage safety activates, then give it a full, uninterrupted charge to completely wake up the deeper cell material.

5. Dry Climate Isolation: Always use and store this charger in a completely dry, well-ventilated space. Unplug the unit entirely from the wall outlet whenever it is not actively charging a vehicle.
