🔋 Battery Care and Safety Instructions
Our packs are built with premium name-brand cells, and a few simple habits keep them safe and healthy for years. Here are the do's and don'ts.
🔋 Battery Storage
Storing your ebike for a while? A little prep — charging to 40 to 60 percent and keeping the pack cool and dry — dramatically extends its life.
🔌 Charging Your Battery & Charger Instructions
Charging your Bafang pack is genuinely easy — the smart charger and built-in BMS stop automatically when it's full. Follow these steps for years of reliable range.
⚠️ Error 04 / 05 — Throttle Error
Error 04 or 05 means the throttle isn't communicating with the controller and won't work. This guide walks you through reseating, isolating, and replacing it.
⚠️ Error 06 — Low Voltage Cut-Off Protection
Error 06 means your battery voltage dropped too low and the system cut power to protect the pack — usually just a sign it needs charging. Here's how to clear it.
⚠️ Error 07 — High Voltage Cut-Off Protection
Error 07 means the battery is delivering too high a voltage and the controller cut power to protect itself — usually a wrong-voltage pack. Here's how to fix it.
⚠️ Error 08 — Hall Sensor Fault
Error 08 points to a fault in the motor's hall sensors, which track the rotor's position. Here's how to fix it, from reseating connectors to replacing the hall PCB.
⚠️ Error 12 — Controller Error
Error 12 is a controller fault — often just a loose connection between the controller and the motor core. Here's how to reseat everything and clear it.
⚠️ Error 21 — Speed Sensor Error
Error 21 means the controller isn't reading your speed sensor — almost always a spoke magnet that's out of alignment. It's one of the most fixable codes, and here's how.
⚠️ Error 22 — Throttle, Battery, or Display Input Error
Error 22 is an input fault tied to the throttle, battery, or display — often just an unexpected button combination. Here's how to track down the cause.
⚠️ Error 30 — Communication Error
Error 30 is a communication fault between the display and controller — most often a simple connector issue or a known bad display batch. Here's how to work through it.
