Yessir. This is what you want. I use a bunch of the accucel-8s which is just the larger version of your charger.Take a look at the multi tap addaptor if you have a large variety of batteries. I have yet to come across a lead it will not work with.
A friend of mine has bought these and although I really appreciate the price and quality of soldering BUT although I don't doubt the Quality one minute, i doubt its NEEDS .
This will only introduce unnecessary resistance into your electrical system
Pros : only price this time
Cons : You are adding resistance to your system Learn to solder or get a mate to do it for you its neater cleaner and better for your system. Adding in effect another 2 plugs into your electrical system is Never good !
You are 'kack' handed and really unable to convert these and you have no mates :(( then u might need these otherwise please buy a soldering iron and have a go ..
