⚠️ Things to Watch Out For
🚫 Not interchangeable with 29.4V (24V systems) or 54.6V (48V systems)
🔌 3‑pin plug must match device inlet — some use 2‑pin barrel or XLR
📉 Overvoltage can damage 24V systems — confirm battery label (36V nominal)
🧪 Check polarity and pinout before using aftermarket replacements
🧯 Avoid forcing into mismatched ports — may bend pins
 
🛠️ Quick Tips for Beginners
🧭 Look for “36V Li‑ion” on the battery/device label — full charge = 42V
🔌 Match the 3‑pin round plug — don’t substitute with 2‑pin barrels
🧪 If device won’t charge, inspect pins for corrosion or misalignment
🧯 Label adapters clearly to avoid mix‑ups with 29.4V or 54.6V chargers
🧵 Treat as the universal 36V lithium charger for scooters and hoverboards
