You said the weight of your 14.4v 5amp Nimh battery weighs about 2 pounds? The 5amp SLA battery that I've got is right around 4 lbs. So we're only talking about a weight difference of 2 lbs from one battery to the other? Considering it's installed on a 39lb hardtail mountain bike converted to commuter, pedaled by a clydesdale rider, I don't know if the 2lbs is worth worrying about. What are the other benefits of the Nimh battery packs? What do you need in the way of chargers?
