Hello Pete; I'm sorry to say there are no replacement converter sections available for the 4135. Have you checked to see if you have the lithium switch on yourse? See the attached pictures which show the location of the switch. If you do not have the switch the only option would be to completely replace it with the Progressive Dynamics # PD4045KA which is lithium compatible.

Thanks,that's what I was afraid of. Mine does have the switch, but it won't put out more than 13.6 volts. Is this brand any good or should I look at others?
