Weize Lithium YTX20L-BS, Group 20, 600A LiFePO4 Motorcycle Battery, 12V 8AH ATV, UTV, Jet Ski, 4 Wheeler, Snowmobile, Personal Watercraft, Seadoo, Polaris, Generator and Riding Lawn Mower Battery

It's only been a day or two, but when I installed it - IT WORKED! It's a battery. It did what batteries do. Rolled over all 103 ci of my '15 HD without any struggle at all. I did however put the (special lithium) charger on it overnight, so that was fresh. Ask me again in a year or two when I've had a chance to develop a bit of history with it.

Great battery!! My battery on my tracker 570 Atv so I ordered this one. This battery has twice the cca that my old one did and it weighs like a pound. It’s so light and has so much more power. Highly recommended.

Incredibly light weight. Purchased for my 2010 Street Glide. I've heard older vehicles charge at a higher rate and may not like LI batteries but so far so good.

Works, a lot of power for the size, and it is much lighter than a lead acid. The self discharge rate seems higher than I expected, if not using seem to need to top it off every 2 months. Especially when the temps approach mid 30s f. (ended up bringing it inside for the winter).

Works great on my motorcycle, 2008 Harley Softail deluxe. Start very strong and very lightweight! Just make sure you don't use a regular charger to charge a lithium battery. You need a lithium charger!

I was skeptical that this battery was as good as described, and when I received it and picked up the box! I thought there is no way this battery is going to start my Harley, it is the lightest battery I have ever held. It started it perfectly, I am beyond impressed to be honest!

Just put in my 2001 FLH with 10.5 to 1 compression with compression release will be updating in the future on cranking performance. super lightweight compared to acid battery’s is a plus hope it handles the vibration stay tuned !

Lite weight and ame fully charged. Fast delivery. My only complaint is that it is pricey compared to standard agm battery.
