The difference in range, torque and top speed is really noticeable over the original CTY 2 battery. The only complaint is the fit with the CTY2 wood cover is just not good. I purchased a gap filler from Z Creations and that's done the trick as far as aesthetics goes. Excellent battery performance thus far.

Best batteries and customer service in the business!

Great service fast shipping!

Great battery work, great power delivery and range.

48V 'Atlas' Range Extender Battery for Super73 R, RX, S2

72V 'Hyperion' Battery for Onyx RCR

No more range anxiety. And always great power even half way full. Will recommend to get the extended battery

I can't say enough good things about my 72V 50AH Powerful Lithium battery. Not only is the range way more than I expected but it has a higher discharge. Plus the peace of mind knowing I have a safe, high quality battery that was hand built here in America by the team at PL. Great communication too, they recommended a charger too that I am also very pleased with. Five stars all around.

Powerful Lithium batteries are the best on the market! I will only run there batteries on all our companies builds! Switchback Electric Bikes LLC

Great service

Good experience, battery is really nice fits easily, my bike has the seat extensions. Bought a Sotion motor first for a great price also

Love the 60V 60aH battery pack from this team! My Roadrunner Pro can now go 75-100 miles vs. the 32ish miles I was getting before adding this extender. Thanks Powerful Lithium!

XR Extended Battery Cover for Onyx RCR

The extra power and range this battery has over stock 41ah battery is way better. It is what I needed for my bike. Paired with a Fardriver 84680 = insane

I initially ordered a 17aH, but they were able to change my request for a higher aH with no problems. The battery was custom made to fit my Fiido Q1s and fits perfectly around my controller set up. Great job!
