Right.

Yes, but LiFePO4 are a better choice for most ham applications. They are 
a safer battery, and the discharge curve of a nominal 14.2V pack stays 
above 13V for most of its capacity, as compared to lead-acid chemistry, 
which stays below 12V for most of their capacity.   Here are two good US 
vendors. The second one, Battery Space, also sells a broad range of Li 
Ion batteries. Both vendors have good people to talk to on the phone and 
via email. Bioenno has been exhibiting at hamfests, and their products 
are sold by Ham Radio Outlet. I've made them aware of the RFI issues 
associated with their chargers, and they are working on finding suitable 
replacements.
