Other way around Stephen. 55 amps DC pulls about 5.5 amps on the AC side. (that is an approximation)

Thanks. I messed up my calculations when I wrote that. You said what I meant to say. I was thinking that if the 55A were the 120V AC, it would be over 300A DC. It is better to put it in terms of what the actual AC draw is to generate the 55A (maximum) DC output.

With lithium iron batteries you need a compatible converter charger, a compatible solar controller, (if using solar) and a compatible B2B charger if you plan to charge lithium from your tow vehicle. (do not believe the marketing about lifepo4 being drop-in replacements...they kinda are but they kinda aren't. Like 'unlimited' cellular data)

You might have missed the part where I said, open up that wallet.

Not much. That is the key to my using the word 'choose'...I CHOOSE to not use much power. So again, restating my previous position:

I have not run out of power no matter what I choose to operate...

In other words: I have enough power for everything I choose to use.

We already know it's not a lithium charger. Sorry to see they don't have a add-on or direct replacement. I'm awaiting response now from Progressive Dynamic's. Believe they do.


It does look like PD makes a drop-in replacement for the WFCO converter that will properly charge LiFePO4 batteries.


The model number to replace the WFCO converter is PD4655LIV (55-AMPS). It is available here:


Sorry, I missed this.

Your first link is what I was looking at from them. My post (I guess above now) links the unit I think is best suited for us. 
The second link is a 55a unit which I would wonder what that could possibly do since we only have a 30a system. You tell me, I'll listen.. Information aids to decision!

I thought it was you I read about in another thread that has a portable lithium similar to mine. I use mine as I believe you use yours, auxiliary power, augmenting the house system. 



Mine is not portable, I physically mounted the Battle Born lifepo4 battery and associated components inside the camper...there are still 2 lead acid batteries and all of their associated components present. 

The lead acid system makes sense for powering factory installed house loads, and with nothing else to do, they run those minimal loads just fine.

The lifepo4 battery powers any additional loads that I add, such as 12v fridge, 12v fans, inverter, ham radio, laptop, etc.

I supplement the system with generators AND a solar panel system, inverter, and even more batteries in the bed of the pickup. 

I have not run out of power no matter what I choose to operate or the reduced solar input from cloudy or rainy weather conditions. And the cost was reasonable, unlike a typical full-blown 100% lithium system.

Great afternoon spent with a friend that is a EE and loves a challenge. He had an 'early out' and spent it with me! Ya, thats a friend!

We went through so much it's hard to explain.. Some of which, I shouldn't.. I have an extended warranty to think about.

Can he devise a circuit to do what I wish? Yes. Can he detail it so I can build and learn from it? Yes, he's done this before and have learned so much from him. The question became if it was worth it...

Past projects we have done together have been well worth the effort and result. This one seems to be, if the responses to the questions work, just buy the unit.

This is the Promax Boondocker relabeled as the Boondocker. Reason for this one over the other is the adjustments already built in. No other component required.

Next was my first found and do believe a good unit is the: http://www.progressivedyn.com/specialty/inteli-power-pd9100l-series/
I'm awaiting an answer to learn if adjustable or if you have to buy the 'wizard' to do so. 

Reviews so far are good on both. So I see it as a choice of benefit of which.

More to come as answers come in and I review with my EE buddy first. 

P.S. Don't bother going to WFCO with questions of any technical nature. You'll get better results here! Trust me and save the frustration.
