TYKOOL YTX9-BS -STD 12.8V 4Ah, 240CCA Lithium LiFePO4 Motorcycle Battery,2X Cranking Amps,5X longer life,Powersports battery,for ATV,UTV

Great battery, fits properly, holds a charge. No problems. I fabbed and welded in a bigger battery box to fit this battery for my girls 110cc e start pitbike to replace the claaped out lead acid. This baby has sone serious power! Never struggles to turn the engine. Were happy!

I’ve had it about 6 months. I bought it for my old 2006 Kawasaki Brute Force ATV. Its has a carb and doesn’t like to start especially in the cold. Even after changing the vacuum fuel pump to electric fuel pump. A guy online recommended changing to a lithium battery as you get full cold cranking amps even if the battery isn’t fully charged. He stated it should help with starting the old Brute Force and he was right! I live in New Hampshire so it gets pretty cold. In the spring, summer and fall it starts almost instantly like its fuel injected. In the winter, when it doesn’t like to cold start at all unless I use starting fluid. It starts after 3-5 seconds of cranking. Very happy with purchase so far. The manufacturer recommends a 2 amp trickle charger. I use a Noco Genius 2 to charge it every month or 2 which works fine. Would definitely recommend this battery and charger.

These batteries are AMAZING. I'll never buy another AGM / lead acid again. They're super light, like 3 lbs light. Puts out a lot of both CCA & CA amps. Price is very fair. Warranty is great compared to traditional batteries. Perfect fit. Quick easy install. I "show and telled" my battery to my other biker buddies, and they all bought one on the spot. I just hope I feel the same way 1, 2 or even 3 years down the road when it's still working unlike an AGM that if you get a year out of you're doing good. I expect this one to last much longer than just 1 year though.

Bought this for a motorcycle and it worked great for a few months. While on a ride my bike completely died in the middle of the forrest with zero cell service. It turns out the battery was the culprit. A friend had to ride over an hour out of the trail to get a new battery. It appears I'm not the only one whose battery dies after a few months. I wish I could return it but I'm well over the 30 day return period. Will update this review once I contact Tycool for a new battery and see if the new battery will last more than 6 months.

Extremely light weight and too large to fit a 500 sportsman but i was able to make it work. Great battery would buy again

It's light. Good. Arrived fully charged.

Worked great on my side by side, like the voltage meter, easy to handle weight is less,

Fits perfect on 2014 Honda Ruckus. Starts right up!
