The 16X512 charger is neat. I just wish it had memory for different batteries. It is a great little unit with temp cutoff and step charging and all the motor testing functions. The charger is not hard to use. I have the !6X5v6 so I know the integy menus. If you have questions I may be able to help. e-mail me at

I have have been able to get ahold of Bill at integy at
[email protected] but it can take a week or two for you to get a response.
In a bind the 16X8 should have very similar menus. The major difference is the 16X8 has a discharge function I do not think the 512 has.
