Upgrade Kit for Parallax 7155 Converter/Charger to Use with Lithium Batteries

Question

Question:

Can you tell me if the PD4655LIV would be a good lithium option replacement for our Parallax 7155 Converter/Charger? Will this fit into the same housing that is currently there and will it match up with the screws for securing the device to the RV?

Yes, we have spoken with Progressive Dynamics in the past and the Lithium Converter for WFCO RV Power Centers # PD4655LIV does fit your Parallax 7155 Converter/Charger. The housing is the exact same so it will bolt right up. This a really great option to convert the setup you have now to be able to charge lithium batteries. The big difference with lithium batteries is that they require higher voltage to charge which is why the output of this is 14.6 volts DC.

The Replacement Converter #PD4655V is the correct converter for your Parallax 7355 power center. I do not see that WFCO shows their 8955PEC being acceptable to use with your Parallax 7355.
