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 of 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. This ensures that the internal cells stay balanced with no special charger necessary.

With Q4 terminals for versatile and simple hookup, and 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 any major Lithium LiFepo4 or Lithium Ion battery. For use in motorcycle, ATV, scooter, snow machine or UTV (side by side) starting applications.

Scorpion Stinger

  • The highest standard in Lithium powersports batteries available.
  • Heavyweight punching power in a featherweight package.
  • Scorpion Stinger LiFePo4 batteries are lighter and perform better than their competition.
  • More options. Scorpion Stinger makes available more case sizes than any other Lithium battery manufacturer, meaning you get a battery that fits your application as it was meant to.
  • Cells are internally balanced-no special charger necessary
  • 2 year free replacement, with additonal 1 year pro rated from date of purchase when used in prescribed applications*


  • Light weight Lithium Iron Phosphate Technology
  • Superior Cranking Performance
  • Charges in as little as 6 minutes
  • Can be charged with any Powersport Smart Charger meant for Lead Acid or LifePO4 Batteries


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.

This battery normally ships via USPS Priority mail, with expected* delivery time of 2-4 days. MAKE SURE YOU USE A POST OFFICE DELIVERABLE ADDRESS! Customer will be responsible for shipping charges on returns for undeliverable addresses.

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

Dirtbike battery
Pros: Just got this battery about a month ago, but it\'s been great! My cousin bought a $25 e-bay special and it\'s junk. So I fork out the extra for this one, and I have no regrets! Bike rolls over fast and strong, fires right up. Their staff was very helpful when I had a problem with my shipping address, and got the battery shipped right away.
Cons: Battery was so light, I thought they shipped me an empty box. I guess that\'s not really a con……..oh well, worst thing I could think of.

Good on a BSA
Pros: Size Weight Terminal Location Charging Speed
Cons: None
Got it in the mail and couldnt believe how light it was! Pulled it out and its not much bigger than a coke can! Needed to use the foam pads to make it fit in my bike, but fits nice and makes the bike run! No electric start so I cant say how the power is for that, my bikes kickstart!

Still kicking strong
Pros: Strong battery, innumerably times better than the POJ Walmart battery I had to pick up in a pinch. Mind-blowingly light for a battery that packs this much power.
Cons: Price of course
No regrets about purchasing this battery. Spins the motor with ease on my YZ cammed WR450, even after setting for 5 or 6 weeks.

Worked great for awhile
Pros: Light weight Cranks quickly and efficiently Looks awesome
Cons: Only if it dies
This battery was perfect at first. I also really enjoyed working with the people at I initially ordered too large of a battery and they were very helpful in the return process. However, about a month after having this battery my 3 year old apparently turned the gokart lights on and the battery died completely. I also purchased the optimate charger which seemed to fully revive it. However, it will now no longer hold a charge for more than a day or two. I have had the battery for about 4 months or so. Be very careful never to let the charge run all the way down or you have a cool looking, expensive, paper weight. Bummer.

Great R1 battery
Working good so far in my 2016 R1, Not sure about the cranking amps though. Very light weight and seems to do a good job. Hope it lasts!
