Scorpion Stinger Logo

The new Scorpion Stinger Lithium Iron Phosphate battery offers an increased performance over traditional lead-acid chemistry batteries, while also shaving an incredible amount of weight off the battery.  These Scorpion Stingers will crank your bike, atv or scooter easily, while also weighing up to 60% less than the OEM lead acid. 

Scorpion Batteries are made by one of the largest battery manufacturers in the world and uses their prominence and experience to create the best products possible at the least possible cost.

Scorpion Battery was founded on the principle that superior quality batteries can be brought to the market at an economically pleasing price. Keeping true to that principle, Scorpion is proud to now offer the finest LiFePo4 Lithium powersports batteries available anywhere.

Scorpion Stinger lithium powersports batteries bring innovation to a new level. All Scorpion Stinger batteries use only the finest prismatic lithium cells, meaning that you get stronger starts, and more cycles than our competitors. Each battery contains its own Battery Management System built right into the battery ensuring that the internal cells stay balanced.

Features an onboard charge level display with the push of a button! The Scorpion Stinger Lithium Powersports batteries are simply the best lithium battery out there, and to top it off, they are offered at the best MSRP of most major Lithium LiFepo4 or Lithium Ion battery. For use in motorcycle, ATV, scooter, or UTV (side by side) starting applications.

BatteryStuff understands the importance of getting a replacement battery right away. We usually ships all batteries the same day as ordered if received before 1:30pm (Pacific).


  • The highest standard in Lithium powersports batteries.
  • Heavyweight punching power in a featherweight package.
  • Scorpion Stinger LiFePo4 batteries are lightweight and designed to outperform their equivalent OEM Lead Based Battery.
  • Superior Cranking Performance
  • Quickly Re-Charges after start in as little as 6 minutes
  • Integrated BMS works with existing charging systems on bikes 1990 and newer.**
  • Recommended to be maintained with a Powersport Lithium Charger. We suggest the OptiMATE TM-471.
  • Warranty: 2 year free replacement when used in prescribed applications*.


As the graph below suggests, Scorpion Stinger batteries hold a higher resting voltage than other batteries. They start higher and finish higher, meaning that during times of heavy load they have the ability to crank the starter faster and longer than the competition. For starting batteries, most of the work happens in the first 5-10 seconds. More voltage throughout that range ensures quicker starts and less strain on the starting system. Scorpion Stinger Performance Comparison

All the test batteries were fully charged and maintained for 48 hours on shop grade smart charger. Starting voltages achieved by fully charging batteries, then removing battery from any outside input for 24 hours. Each battery was tested under equal conditions at 72° F, using a true 100 AH load to simulate starting.

Scorpion does not rate their batteries with an AH rating*. Instead, they graph out the real performance of the batteries, side by side the best lead-acid and lithium batteries on the market. This gives you the confidence to know exactly how much starting power your Scorpion Stinger has, without giving a seemingly inflated number, or a confusingly low number that is not practical. *See more detailed explanation here.

LiFePo4 Batteries are sensitive to heat. If the battery will be sitting directly on top of the engine and/or surrounded by the oil pan, we do NOT recommend using any Lithium Battery.

**Over-Charge protection will not protect from a faulty/old Voltage Regulator spiking Hi-Voltages to Battery. If you have a Pre-1990s Motorcycle replace your voltage regulator; it is over 30 year old and most likely broken by now.

*Warranty applies ONLY to vehicles listed below. As per manufacturer, ALL other use will void battery warranty.

Lithium battery salvation
Pros: Battery solved the problem -after worrying about adequacy of charging, a short in the system, etc. The very light weight of the battery was a big plus also (for an old guy who is no longer so powerful as back in the day).
Cons: None - fit perfectly. Hook up same as the old battery.

Great battery
Pros: Very light - a real shock after lugging lead-acid batteries around my whole life. Great cranking power.
Cons: Initial cost.

At first I was dubious, but WOW
Pros: Light weight. Almost too lightweight. Seems like an empty box, but brother it's not! It fit my R1200RT almost perfectly, it's got a nice charge indicator on the top, and MAN can it put out the amps for starting. In all the years I have had this bike it's never cranked and started so fast. So far no problems of any kind.
Cons: First capacity. I used a West Mountain computerized battery analyzer to test it's "reserve capacity" Using standard test methodology for lead acid batteries it's only got a 12 minute rating. After recharging the amp hour capacity came out to 7.3 AH. If you like to listen to your radio after the bike is off the battery will drain very quickly - but now you know this. Off with your electric clothes, off with the radio right away.
This battery seems to have a built in BMS (battery management system) so the LiFePO4 cells should stay balanced. Although I have wanted to cut this battery open to see what's inside I have refrained, it appears to be an empty plastic box. The size was slightly (and I mean only slightly) smaller than the OEM Gel Cell, it required some shimming to keep it from rattling around, which it will do to the fact it weighs almost nothing!

Don't waste your time and money on these!
I have purchased two of these batteries and BOTH of them failed beyond repair in less than two years. I will never buy these every again.

***Note From BatteryStuff***
Customer was only able to provide proof of purchase for one battery from, however customer sent two batteries in for warranty testing. Both batteries received for warranty were at an excessive discharged state showing lack of maintenance charging, which can affect the life of a lithium battery. Batteries received at an excessive discharge state are ineligible for warranty, as warranty only covers manufacturer defect. As an exception we issued a pro-rated warranty to store credit for the one we had proof of purchase for as it was purchased over two years ago. Customer was advised the importance of maintenance charging as lithium's are only 1/3 the capacity of the original battery. Customer ended up using store credit to repurchase the same lithium.

Great product.
Great product and fast service. Product was as advertised and arrived in good condition. I installed the battery and it has been working just fine.

Much more power than my ordinary bike battery.
I had hoped that the 2005 K1200LT would reverse smoothly, like it did as a motorcycle using a less powerful motorcycle battery, but as a trike, using your Scorpion Stinger lithium battery in the conversion, it still reversed in fits and starts -- six short spurts to back down my driveway, although more powerful. ???
