Appearently some BMWs have even more complex and sophisticated battery charging systems? I don't know much about them. I found this that said they were lithium ion. $1700 or something crazy? Supposedly some M-cars have lithium ion so the braking recuperating charging works? That would mean they probably need charger capable of properly charging a lithium ion battery to BMW specs. That might be the special BMW Ctek charger the Toyota tech was referring to?no. they ae agm. glass mat. not lithium
