I upgraded my original converter charger to this one when I switched to lithium. It charges up to 14.6 volts, which is what my lithium cells need to be fully charged. It's not programmable, so look elsewhere if you need programmability and Bluetooth. It works and I've had good luck with progressive dynamic products.
