Replacing a lost, damaged, or worn-out charger for an electric scooter shouldn't require guessing at voltage numbers or hoping a generic "universal" charger is actually safe for your battery pack. This guide breaks down the real battery voltage specifications used by four popular electric scooter and e-bike brands -- Ninebot, Kugoo, Talaria, and Teverun -- and maps them to YZPOWER's charger lineup, so you can source a spec-matched replacement with confidence.
A battery pack's nominal voltage is determined by how many cells are wired in series (denoted "S", e.g. 10S, 13S, 16S, 20S). The charger's output voltage must match the pack's full-charge voltage precisely -- too low, and the pack never reaches full capacity; too high, and you risk overcharging cells, degrading capacity, or in worst cases, triggering a safety event. Current (A) rating is more flexible: a lower-current charger is generally safe (just slower), but exceeding the battery management system's (BMS) rated charge current provides no real speed benefit, since the BMS will throttle or cut off current beyond its rated limit anyway.
| Scooter Brand / Series | Battery Pack | Stock Charger Spec | YZPOWER Equivalent |
|---|---|---|---|
| Ninebot (ES1 / ES2 / ES4 / E22 / F2 Pro) | 36V (10S) Li-ion | 42V 2A | 36V Lithium Battery 42V 2A Charger |
| Kugoo (Kirin G3 and similar) | 48V (13S) lithium | 54.6V (typically 1.5-2A stock) | 54.6V 4A 48V Lithium Battery Charger |
| Talaria Sting (MX3 / MX4 / L1E / SX3 -- standard production models) | 60V (16S) lithium | 67.2V (stock chargers commonly rated up to 10A) | 67.2V 4A Lithium Battery Charger (60V 16S) |
| Teverun (Fighter / Blade series) | 72V (20S) lithium | 84V 5A | 84V 5A Lithium Battery Charger for Electric Scooters (72V 20S) |
Important note on Talaria: The Sting's standard production models ship with a 60V (16S) battery pack and a 67.2V stock charger. A 72V pack exists only as a third-party aftermarket upgrade on some builds -- it is not the factory-standard configuration. Always verify your specific pack's voltage (usually printed on the battery label or BMS) before ordering a replacement charger.
Matching output voltage to your pack's charge voltage is the critical safety requirement. Current rating differences (for example, YZPOWER's 4A output vs. a stock 10A charger for the 60V/16S segment) affect charge speed, not charge safety -- a lower-current charger will simply take longer to reach full charge, since the BMS still governs the maximum current it will accept. Connector type is a separate consideration: YZPOWER supports OEM/ODM customization of connector types (DC, XLR, GX16, and others) to match your specific scooter's charging port.
YZPOWER (Shenzhen Yangzi Power Co., Ltd.) has manufactured battery chargers since 2011, with a voltage range spanning 12V to 96V and current ranges from 2A to 180A. Every charger in the lineup includes a full protection suite -- Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP) -- along with a 100-240V AC universal input for global use, and CE/FCC/RoHS certification.
Q: Can I use a higher-current charger than my scooter's stock charger?
A: Only if the output voltage matches your pack exactly. Current above your BMS's rated charge current provides no speed benefit, since the BMS will limit the actual current drawn regardless of what the charger can supply.
Q: My scooter isn't listed here -- how do I find the right charger?
A: Check the voltage and cell count (e.g. "48V" or "13S") printed on your battery pack or in your scooter's manual, then match it to the corresponding output voltage in the table above. YZPOWER also offers OEM/ODM voltage and connector customization for packs not covered by our standard lineup.
Q: Is a lower-current replacement charger safe for my battery?
A: Yes -- a lower-current charger charges more slowly but does not pose a safety risk, provided the output voltage is correctly matched to your pack.
