DR.PREPARE 12V 100Ah LiFePO4 Battery with POWERMAX Hub 

This is nice. Keep up the Good work.

great vid, thx for the work.

It comes, with low temp cutt-off, delivers stated capacity, inlcudes an mppt charger, offers a variety of outputs and exposed battery terminals for say and inverter. Its one of the best so far. That the hub is replaceable also bodes well. Currently at $US400 - its a winner. It looks like you can't safely series connect them based on no mention of series connections on their specification page. Nice review Brad. I thought it might have a PTC that Sylvan_dB has already mentioned.

Great job!

Question: can I hook the hub anderson connector to a 20 amp line from the tow rig/ coach (instead of solar)? or will I need a true dc/dc converter?

Sounds like a good design with a PTC reseting fuse. 👍

Can I charge this with my truck running down the road?

The 100ah rating is based on a .2C discharge, correct? The hub is an interesting feature, but with its limitations and the possibility of damaging it just by plugging in something that draws too much power or by simply using the battery while plugged in, it's a no-go. Hopefully hub 2.0 fixes these shortcomings.

You just learned the difference between usbc and a power delivery port. :)

Have you had any trouble charging over 3 bars

Did you charger charge it full? It appeared to not be at/over 14.0v at start. Not much between 13.5v and 14.5v but there are a few amphours...

My 2 month old DR PREPARE with hub stopped accepting a charge and I lost a refri full of food. Plus I am now traveling and have to use daily food purchases. I have sent 3 emails to Dr Prepare..no response.

They really should have implemented the full 20v/100w on the USB-C port with a boost converter, it's not like they were short of power to deal with it, a missed opportunity.

Brad love your video's but pls invest in a tripod.

IMHO, you are WAY too nice brother.. (appreciate your videos btw, super helpful for me so far..just found you a few months ago) If a company tried to tell me that I couldn't charge my little laptop (an item MANY ppl will be wanting to, & expecting to be able to charge) with that massive 12+V / 100Ah battery, I'd be offended that they insulted my intelligence, and frankly laughed in their face..then I'd have put it all in the video, but accompanied by some serious head shaking and some added, "can you believe these guys" in for good measure..?? The only thing that saved this whole thing is somehow it bounced back. I was all about this thing until that happened..I'd be still OK with it if it had died outright, then been a fluke, they sent another, etc., etc..but saying that's too much for it & a breakdown from not having enough protection to avoid failure from such a small & common item is to be expected?!? Um, no.. fix it then before letting it hit the market🤷‍♂.. A "laptop" is far too small and far too common of an expectation IMO to not be able to do. I could even go for absorbing some of the blame on the fact that it didn't get to full charge, if it had just kicked off due to a protection sensor, etc.. but heck they saw the video and STILL gave u the story of it being too much for it? Maybe I'm just an entitled jerk that expects too much, but to me that's Bravo Sierra🤨 (sorry for the 1000 word AAR ;-)

18 volts is not a guarantee of MPPT. PWM controllers run at that level too. 12 volts would be if there was absolutely no controller at all. If the solar panel was connected directly to the battery. :)

Any idea if 'Dr. Prepare' build their own or is this a repackage of another manufacturer?

22:30 - This is baloney from the MFR, if a plugging in a USB-C PD device is what actually fried the hub's USB/12V, they made it wrong, period. A device that is able to charge off of USB-C PD 60W should NEVER 'burn out' a USB-C PD supply only capable of 30W.

Piece of crap....can't get it to charge off solar or cigarette plug. It shows 25% charge on the blue indicater...but no blue or green. Light. 3 months and I wasted a out 75 in food getting warm.
