Thanks Sergei, I like CTEK too I have the 7.0 which is only for lead-acid.
Maybe I could use this little charger I use for my planes
Kidding aside, I think I should be ok, the Voltphreaks battery is very clever and can be charged with a lead-acid charger, I can just use the one I have.
I still need to check the voltage at the battery of my new car, maybe its ok, if not I will need to get an adjustable voltage regulator.
