I will be ordering more Batteries from them in the future.

"I ordered Two Batteries for a Police Mountain Bike to run the 4 Whelen ION Series Super-LED Police Lights and a Police Siren.The Batteries are half the weight of the 12v sealed lead acid battery I was using and now I able to carry 3 times more Amp Hour giving me 12plus hours of reliable service. Batteries arrived well packed, work great, charge fast. A bit expensive but when your life depends upon reliability the price is worth it.I will be ordering more Batteries from them in the future.
