You know the more I try to learn about these things the more confused I get, I guess you just need to take the leap, thanks Vapoor the prices are certainly better.
You're welcome. When you have your PV in hand it makes a lot more sense IMO. If there's anything you want just ask and I'll put a list together. If you get the kit Katya has linked to realize the Twist and Spinner batteries will work with the charger in that kit:

I prefer the Spinner because the dial is knurled/ easier to turn and the voltage markings are more visible- in my old age it helps:

I have no loyalty to any brand or vendor but just look for what suits me best at the right price.
