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). This battery normally ships via USPS Priority mail, with expected delivery time of 2-4 days, however USPS does not guarantee delivery times.

MAKE SURE YOU USE A POST OFFICE DELIVERABLE ADDRESS! Customer will be responsible for shipping charges on returns for undeliverable addresses.


  • 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 most 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.

SST12B-FP Scorpion Stinger LiFePo4
Pros: It is a very light weight battery, comparing to the others I had before. It runs the starter motor faster and turns the engine on quickly.
Cons: It is a much smaller size than the original so I had to use all the rubber padding sent with the battery to fill up the space in the battery compartment. I hope the padding lasts as long as the battery.

Very Light
Pros: Very light battery. Very easy to install because of smaller size. They send rubber spacers with the battery for a custom fit for your motorcycle. No charging and started right up after installation.
Cons: I'll have to use it more but so far no negative's.
The weight reduction alone is a good selling point. I hope it lasts as long as the original 6 years. The next lead acid battery I used lasted 1 season. Will have to wait and see how this deals with the heat of Phoenix.
Installed in an 05 FJR1300

Battery review
Pros: So far this battery has been a champ. I had a new battery box built to accommodate its smaller size and it tucks away nice between the frame and oil tank on this custom chopper. The higher cranking amps, has allowed me a curtain comfort when out on a long ride
Cons: No cons as of yet
. Sales personnel went over the top to ensure my needs were meet. thank you =0)

new battery VSTAR650
Pros: Surprised at how light weight and smaller this unit is, easy install with the supplied spacers and the status lights make it very convenient to check power. Bike cranks and starts with ease even in 30 degree weather, at 8 PM after sitting in parking lot all day, everyday. Headlight and instrument lights are nice and bright even with heated vest and gloves with power turned on, this is a nice +. Unit is about $30 cheaper than OEM at the dealer.
Cons: Non so far

FJR Battery Review
Pros: 1)Light weight 2)Very high cranking ability for instant starts 3)Fast shipping
Cons: None!
When the package arrived, I though who would send me an empty box? When I looked at the return address and saw that it was from BatteryStuff, my first thought was they forgot to include the battery in the shipment! Quite surprised when I opened the box and discovered there 'was' a battery included. But my astonishment did not end there. Once installed, I was once again floored at how quickly my 4 cylinder motorcycle motor started. I own a '05' Yamaha FJR. Never has this thing started so effortlessly. This battery is not cheap, but it is worth every penny of its selling price. Actually, I feel it is a bargain. You will appreciate how easy it is it slip into the tiny battery box on you motorcycle. This is due to its light weight. 5 stars was not enough!
Thanks BatteryStuff, You made my day!

SST12B-FP Scorpion Stinger
Pros: Super light, charge lasts forever, Push button charge status and no special changing equipment needed!
Cons: I can't think of any but, if you make me list something..... I wish it was a bit less expensive.
I love this battery! I have one in all three of my bikes. When and if it goes, I'm definitely getting another!!!!

SST12B-FP Stinger Battery
Pros: Light, small, powerful, came fully charged. Started my Ducati instantly. With the addition of Hi-Capacity cables, even quicker.
Cons: Tiny 4.8 mm terminal screws supplied and holes in terminals too small for my application - Hi Cap cables with auxiliary cables on a 2012 Monster 1100 Evo. I had to enlarge the holes and use longer 5.8 mm bolts and nuts. Small size required lots of padding for OEM battery mount and box to work properly and securely.
Appears to be a well made product. Time will tell. My first try with Lithium motorsports batteries.

Small and light
Pros: The SSTX12B-FP Scorpion Stinger LiFePo4 Quad Terminal Extreme High Output lithium ion battery I bought from BatteryStuff is small and light. In an FJR1300 the battery sits high in the front fairing, and reducing that weight should make balance even better. On top of that I have more power to crank the engine - Nice set of features. Shipping and packaging were excellent.
Cons: None so far.

Scorpion Stinger rocks...
Pros: Small, light, and plenty of CCA capacity!
Cons: None found
My first foray into the LiFePo4 batteries was a Shorai of similar size and nominal capacity that I purchased for my 2009 Road Star. Unfortunately, the Shorai did not have the CCA "oomph" to turn my big twin over at temperatures in the 40's or lower. Enter the Scorpion Stinger - it's rated much higher in CCA than the Shorai and it really performs. Turns my Road Star over faster and catches even easier than the OEM lead-acid battery. I'm sold on Scorpion!

Dead in less than a month sitting in a garage
I purchased this battery for a Yamaha Raider. The battery arrived on 12/6/2018 and was installed on 12/7 after being fully charged. The bike started faster than it ever did on a lead acid battery.

The bike lives in a heated garage. Three weeks later, I tried to start the bike but the battery was dead. The test button on the battery did not cause any of the self test lights to illuminate. I then tried to charge the battery with a ctek charger. The charger could not charge the battery so the battery is completely dead and cannot be charged.

***Note From***
As lithium batteries are only 1/3 the capacity of the typical battery they are replacing we recommend keeping the battery on a lithium charger when not in use. As today's bikes have higher parasite draws you can see how quickly they can deplete a lithium battery when not being maintained with a charger. We highly recommend lithium chargers as they have a recovery mode when dealing with a highly discharged lithium battery. Feel Free to contact our Tech line for assistance in recovering the battery.
