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.

Bought for 1996 FLHT Electra Glide STD
Pros: Good starting power out of the box. Incredible starting (quicker than with AGM). Lightweight at only 1.9 lbs vs HD AGM at 17.7 lbs. CCA is 70 over a stock Harley AGM.
Cons: 13.8v charging power from the bike means it will live at or near 60-80% charge it's entire life (but the battery doesn't mind it and it doesn't shorten battery life). Have to pay attention to overvolt charging, don't go above 15.0v or you will damage the cells and shorten the life of the battery if you use an SLA charger. No balance charging port.
My FLHT has the stock radio system in it, so there's an added powerdraw, but I have replaced every other light in there (except passing lamps) with LED's, saving me gobs of wattage (22 marker/gauge lights @ 5w each + Brake Light @10w + Headlight at 55w with 5w marker light) for a total savings of 180W (or between 12 and 15 amps off the stock 32 amp charging system). Only reason I didn't go with the bigger recommended battery is because I'm not drawing anywhere near what a completely stock bike would draw.

goin strong at 1 year
Pros: very strong, fast crank - that was the selling point to me, and I am pleased with it. Maintenance free. After 1 year, still going strong. It was worth the extra cost to me to know that my bike will start every day.
Cons: none seen yet
I used other (AGM type) Scorpion batteries and they did not pass my approval; they only last about 2 years max for me on both my bikes. I had a slow crank problem on my old Yamaha, and was looking for a higher CCA, this looked good to me, and it is. I am watching for length of use on this battery too, since it is a Scorpion, and after 1 year it is still good. We will see how long it lasts, but my Yamaha spins right over now, every day. I am very pleased.

Only for warm weather
Pros: Love the weight savings. On the BMW F650GS (2006) the battery compartment is up high, where a motorcycle gas tank normally sits. The reduced weight up high improves handling and off-roading.
Cons: I live in the Pacific Northwest. When they say these battery types don't like cold weather - they even mean low 50' or 40's. I ride year round and this is pretty common in Oct., Nov, Dec. and throughout the winter. The bike won't start quickly - you have to let it sit with the lights/electronics on for a few minutes, try starting, let it sit some more...
Having both the Scorpion Stinger and the Shorai LifePO4 Lithium Iron Phosphate - the Shorai held up better. I didn't start having starting delays until a couple years in (and post-when the weather was in the teens for a week.) After that the Shorai started being slow starting up but the Scorpion was that way out of the box.

Since I don't own a car, and only ride, I may even switch back to the AGM battery. at 9lb is less weight than the stock battery but it will be more reliable in colder weather.

awesome performance!
This is my second purchase of this battery. I just replaced my first one - it was 4 years old and was still doing good....until I let it sit with the parking lights on (accidently) for 3 hours. Needless to say, that killed that battery. But, I was so satisfied with the first one, I always said when something happens to this battery I will replace it with the same thing in a heartbeat! I came right home and ordered another one. It has never failed to spin my starter quickly and get the bike running. I have a 30+ year old bike and the original type battery just wasn't cutting it anymore. I never knew if it would start or not, so I looked for a high cranking amp battery. This fits the bill, and does very well. I am well pleased and so have bought my second one. When my old Gold Wing needs a new battery I will look here too.
