Lithium-ion Battery Pack Sting MX4 (60V/43.2Ah)

A genuine Talaria Sting R battery is the most valuable single part on the bike, and this 60V 43.2Ah battery is the unit Talaria fits to the Sting R MX4 at the factory. Whether you want a second pack to swap at the trailhead or a replacement with the correct BMS and CAN communication, this guide covers what is inside it, which models accept it, and how to charge, store and transport it properly in the UK.

Inside the pack: cells, layout and casing

Every Talaria Sting R battery is built around LG 21700 format lithium ion cells rated at 5000 mAh each. The 21700 designation describes the physical cell: 21 mm in diameter and 70 mm long, a size that has become the standard for light electric motorcycles because it packs more energy per cell than the older 18650 format while still allowing a dense, well cooled layout inside a compact casing.

The Talaria Sting R battery runs a 16 series configuration, which is what gives it a 60V nominal rating. Sixteen cell groups at roughly 3.6 volts each land close to 60V nominal, and a full charge sits at 67.2 volts. Nine cells in parallel per group produce the 43.2Ah nominal rating. Talaria markets the same pack as 45Ah in some literature, which reflects the maximum rated capacity of the cells rather than the nominal figure used on the label.

Physical size and weight

The Sting R MX4 specification lists the Talaria Sting R battery at 170 mm by 140 mm by 380 mm, which is the footprint the frame cradle and battery strap are designed around. Talaria quotes 12.85 kg on the MX4 data sheet and 14 kg on the L3E sheet for the same 45Ah unit, so plan on lifting something in the region of 13 to 14 kg when you swap packs. The carry handle is moulded into the top of the case and the pack drops straight into the cradle with the connector facing the controller side.

Capacity, watt hours and real range

Amp hours on their own do not tell you how far a bike goes. Multiply the nominal voltage by the nominal capacity and you get the stored energy in watt hours: 60 volts times 43.2 amp hours gives 2592 Wh, which Talaria rounds to 2.7 kWh in its Sting R literature. That is the number to compare against other packs, because a 72V pack with fewer amp hours can still hold more energy than a 60V pack with more.

Talaria quotes up to 120 km at a steady 25 km/h for the Sting R MX4 on this Talaria Sting R battery, and up to 53 miles on the same 45Ah unit in the L3E and Sting R Off Road listings. Those are figures at a gentle constant speed; treat them as the ceiling rather than the plan.

What eats range on a Sting R

Rider weight on climbs, Sport mode, repeated wide open throttle runs, soft ground and cold weather all pull the figure down, while the four regen levels on the Sting R put a little back into the Talaria Sting R battery on descents.

A second Talaria Sting R battery doubles your day for the least fuss; the higher capacity aftermarket route changes the conversation about charging and weight, and we compare the two at the end of this guide.

Which Talaria models accept this pack

The Talaria Sting R battery is a Sting family pack. The cradle, connector and CAN protocol are shared across the Sting MX3, the Sting R MX4 and the road legal L1E and L3E Stings, which all run a 60V system. The MX5 Pro moved to 72V, and the larger Talaria models run different electrical systems entirely.

Sting MX3 owners often buy this 60V 43.2Ah battery as a modest range improvement over the original 38.4Ah unit, and because the Talaria Sting R battery shares the connector and BMS protocol there is nothing to reconfigure.

The BMS and how it talks to the bike

Every genuine Talaria Sting battery contains a battery management system that monitors each of the sixteen cell groups. It stops charging when any group reaches its upper voltage, cuts discharge at the lower limit, balances groups during the final stage of a charge, and refuses a charge when the cells are too cold or too hot.

What separates a genuine Talaria Sting R battery from a generic 60V lithium block is the CAN bus link. The Sting R OLED display communicates with the BMS and the controller over CAN, which is how the dash shows battery level, voltage, cycle count and error codes. A pack without the correct CAN protocol may spin the motor but will leave you without accurate battery data and can trigger error codes on the dash. The genuine Talaria Sting R battery carries the right firmware from the factory.

Why occasional full charges matter

Because the BMS balances at the top of the charge, a pack that is only ever charged to 80 percent can slowly drift out of balance. A full charge every few rides restores it. This is also why a Talaria Sting R battery should be charged with a 60V charger matched to its 67.2 volt full voltage, and never with a 72V charger intended for a different pack.

Charging a Talaria Sting R battery the right way

The correct charger for the Talaria Sting R battery is the stock 60V Talaria unit, which delivers 12 amps at the 67.2 volt charge voltage. Talaria quotes roughly three hours from empty to full for the Sting R: 43.2 amp hours divided by 12 amps is about three and a half hours of bulk charging, with the current tapering as the BMS balances the cell groups. Our Sting R MX4 OEM charger listing explains the input voltage question for UK buyers.

A charging routine that protects the cells

1. Let the Talaria Sting R battery cool for twenty to thirty minutes after a hard ride before plugging in. A warm pack charges less efficiently and the BMS may refuse the charge until the temperature drops.
2. Connect the charger to the pack first, then switch on at the wall. Disconnect in reverse order.
3. Charge in a dry, ventilated space away from anything flammable, and never leave a charging pack unattended overnight in a living area.
4. Let the charger finish its cycle so the BMS can balance, then unplug rather than leaving it connected for days.

Cold matters more than most riders expect. Lithium ion cells should not be charged below freezing, and the BMS in this pack will inhibit charging when it detects the cells are too cold. Bring the pack indoors to a cool room and let it warm before charging on winter mornings. Our Talaria charger guide goes deeper on charge rates, timing and what the charger lights mean.

Storage, winter and long term cell health

Lithium ion cells age through use and through simple calendar time. You cannot stop either, but you can slow both, and the two biggest levers are the state of charge the pack sits at when idle and the temperature around it.

Storing a Talaria Sting R battery full for months at a time accelerates calendar ageing; storing it flat risks the BMS shutting the pack down below its recoverable threshold. Somewhere between 40 and 60 percent is the sweet spot for a pack that will sit through the winter. Check it every four to six weeks and top it back up if the display shows it drifting down, since the BMS itself draws a small standing current.

Where to keep a Talaria Sting battery

• A cool, dry room between roughly 10 and 20 degrees Celsius is ideal. Unheated garages that fall below freezing and conservatories that bake in summer are both poor choices.
• On a shelf or floor, upright, with the connector covered against dust and damp.
• Away from exits, and out of the bike if the bike itself lives somewhere damp or very cold.

Keep the connector clean with a wipe down before the first spring ride. If the pack has been dropped hard, has a cracked case, smells of solvent or gets warm while resting, stop using it and talk to us. A damaged Talaria Sting R battery is not something to ride through, and the pack is covered by our UK warranty, full terms on the warranty page.

Transport, carriage and disposal in the UK

A 2.6 kWh Talaria Sting R battery is classed as dangerous goods for carriage, which is why it ships in UN38.3 tested packaging and cannot be posted back in a jiffy bag. If you need to return one, contact us first and we will arrange compliant collection. UK mainland delivery, timescales confirmed at checkout.

In your own vehicle, secure the Talaria Sting R battery so it cannot slide or tip, keep it out of direct sun, and never carry a pack you suspect is damaged.

End of life

Under the UK batteries regulations, industrial lithium batteries must not go into household waste. The GOV.UK batteries and accumulators guidance sets out the obligations and compliant take back routes. As a specialist retailer we can advise on returning a worn out pack for recycling, and most local authority recycling centres accept lithium packs at a dedicated point.

A pack that has lost some capacity is not scrap: many owners keep it as a short ride spare. Just do not open the case. There is no user serviceable part inside a Talaria Sting R battery, and disturbing the cell groups creates a genuine fire risk.

Spare pack or bigger pack: how to decide

Two packs, swapped at the van, remains the simplest way to double a Sting day: stock weight, stock charger, factory CAN behaviour, no waiting. The alternative is a single higher capacity pack such as the 60V 65Ah EBMX battery, which fits the same compartment, runs on the stock controller and carries far more energy, at the cost of a heavier lift and a longer charge on a 12 amp charger.

The right answer depends on how you ride. A rider who does a couple of hours on private land with a break in the middle is served perfectly by a second Talaria Sting R battery. A rider heading out on long enduro loops where a swap is not practical will value the bigger single pack. Every battery and charger we stock sits in the Talaria batteries and chargers category.

One reminder on the law: the Sting R MX4 and Sting R Off Road are off road only machines, and extra battery capacity does not change that. They cannot be ridden on public roads, byways, bridleways, footpaths or pavements in the UK, only on private land with the landowner’s permission. If you want to ride lawfully on the road, the L1E and L3E Stings are the models to look at, and the GOV.UK guide to riding a motorcycle or moped sets out the licence and registration steps.

Frequently asked questions

Is this the same battery that comes fitted to a new Sting R MX4?

Yes. This is the genuine Talaria Sting R battery, a 60V 43.2Ah pack built with LG 21700 cells, the same BMS firmware and the same CAN communication the Sting R uses to show battery data on its OLED display. It is sold as a replacement or as a second pack for swapping, and it is covered by our UK warranty, full terms on the warranty page.

Why does Talaria call it 45Ah in some places and 43.2Ah in others?

The two figures describe the same pack. 43.2Ah is the nominal capacity used on the label and in our listing, while 45Ah is the maximum rated capacity of the LG cells. Talaria marketing tends to use the higher figure. Either way the stored energy is about 2.6 to 2.7 kWh, and range on the bike is unaffected by which number is printed.

Can I charge this pack with a 72V charger?

No. This is a 16 series 60V pack with a full charge voltage of 67.2 volts. The Talaria Sting R battery must be charged with a 60V charger such as the stock Talaria unit. A 72V charger targets 84 volts and is intended for 20 series packs; connecting one is unsafe and the BMS should refuse it, but do not rely on that. Match the charger to the pack.

How should I store the battery over winter?

Store the Talaria Sting R battery at around 40 to 60 percent charge in a cool, dry room, ideally between 10 and 20 degrees Celsius, and check it every four to six weeks. Avoid leaving it full for months and never let it sit flat, since the BMS draws a small standing current and a deeply discharged pack may not recover.

How do I dispose of an old Talaria battery?

Never put it in household waste. Lithium packs of this size are covered by the UK batteries regulations and must go through a compliant recycling route. Contact us to arrange return and recycling, or use the dedicated lithium point at your local recycling centre. Do not open the case or break the pack down yourself.
