The 80V 20A adjustable charger is a smart charger built for 22s lithium-ion battery packs. It fits Sur-Ron and Talaria electric motorcycles, and it also works with e-bikes and electric scooters running the same pack configuration. Charging current is adjustable up to 20 A. A built-in display shows voltage, current and charge level in real time.
This unit works with 80 V class batteries. The 22s designation means 22 cells wired in series, so a fully charged pack sits at roughly 92.4 V. Compatibility is therefore decided by cell count, not by the badge on your bike. Any 22s pack with a suitable BMS and matching connector can be charged here.
Because the current is adjustable, you set the charging speed yourself. A higher setting shortens the wait between rides. A lower setting is gentler on the cells and extends pack life. One device covers both slow overnight charging and fast top-ups during the day.
Key Benefits
- Adjustable current up to 20 A – dial in the rate that suits your pack and your schedule.
- Real-time display – voltage (V), current (A) and charge percentage are visible at the same time.
- 22s Li-ion profile – tuned for 80 V class packs with a full-charge voltage near 92.4 V.
- Active cooling – the internal fan holds a steady temperature throughout the charge cycle.
- Connector matched to your bike – state the required plug type in your order comments.
- Broad application – suits Sur-Ron, Talaria, e-bikes, e-motorcycles and electric scooters with 22s packs.
- Simple operation – connect the charger, set the current, then watch the status on screen.
- Battery preservation – reducing the current is the easiest way to extend service life.
Who Is This Charger For?
This charger is made for Sur-Ron and Talaria electric dirt bikes fitted with a 22s (80 V class) lithium-ion battery. That includes the Sur-Ron Light Bee and the Talaria Sting, along with other models built around the same pack architecture.
It also serves electric bicycles, other e-motorcycles and electric scooters using the same 22s configuration. Compatibility depends on cell count and pack voltage rather than the vehicle manufacturer. Consequently, any 22s battery with a correct BMS and connector can be charged with this unit.
However, 60 V packs (16s or 17s) and 72 V packs (20s) are not suitable. Riders who cover high mileage will value the shorter pause between rides. Likewise, owners who prefer to choose their own charging mode benefit here, whether that means a slow night charge or a quick daytime session. Sur-Ron and Talaria do not manufacture this charger; those names indicate compatibility only.

Why Choose This Charger?
Most standard chargers run at a fixed current. Here the current is adjustable across the full range up to 20 A. As a result, one device replaces two: a slow charger and a fast charger.
The screen reports three values at once. You therefore need no separate voltmeter or phone app to read true pack voltage and charge level. That is genuinely useful when checking battery condition after a long ride.
The connector is matched to your vehicle because you specify it when ordering. The charger consequently arrives ready to use with your Sur-Ron, Talaria or other 22s machine. Active cooling keeps the unit stable even at the higher current settings.
Frequently Asked Questions
Will this charger work with my Sur-Ron Light Bee?
- Yes, provided the bike uses a 22s (80 V class) lithium-ion pack.
- Full charge voltage on such a pack reaches approximately 92.4 V.
Is it compatible with a Talaria Sting?
- Yes, Talaria models with 22s batteries are supported.
- Specify your connector type in the order comments so the charger arrives ready.
Can I charge a 60 V or 72 V battery with it?
- No. Packs built as 16s, 17s or 20s fall outside this charger’s profile.
- Only 22s packs in the 80 V class are suitable.
How do I choose the charging current?
- Set a higher current, up to 20 A, when you want a shorter wait.
- Set a lower current for gentler charging and longer pack life.
What does the display show?
- Voltage in volts, current in amps and charge level as a percentage.
- All three readings appear simultaneously during charging.
Does it get hot during fast charging?
- An internal fan provides active cooling throughout the cycle.
- Temperature protection is included as standard.
Which connector will I receive?
- The connector matches the model you state in your order comments.
- Check your existing charge port before ordering.
Can I use it with an e-bike or electric scooter?
- Yes, if the battery is a 22s pack with a working BMS.
- Cell count and voltage decide compatibility, not the vehicle brand.
Set the current, connect the plug and watch the readings climb toward 92.4 V. Whether you ride a Sur-Ron, a Talaria, an e-motorcycle or an electric scooter on a 22s pack, this charger handles both the patient overnight charge and the quick turnaround between laps.
