Anyone here rolling a Voxx backup battery/starter?

Voxx Power Systems Backup Battery

Wondering if you’ve had any issues reliably jumping the V8; maybe battery drain from the trickle pulling too much; or other problems.

Thinking of getting one to free up the space my portable jumper takes in the cab.

 

Interesting concept shipmate. Can you use it without the app? Read through the description, but didn’t see if there is an alternate way to activate it.

 

Wondering that too but not sure. I did notice the device has a

I was wondering that too, but not 100% sure. There is a button on the controller, which gets mounted on the floor under the driver's seat (and then wired under the sill, through the firewall grommet, and then directly to the battery). It's a "Go"/"Status" button, but it's not clear to me if you can also use it to execute the jump itself. It's a simple phone app, but I'd prefer to have a manual option just in case. Not necessarily a critical need, but seems kinda silly not to have that as an option.

 

Never mind. I finally found the official website:
https://www.rostra.com/vps/

"In the event ... phone battery has died, or the phone is not present, the manual switch on the device can be activated with just a press of a button."

 

Seems unecessary to me. My jump box takes up about as much room as a small loaf of bread, can be used on other vehicles as well and only cost $64.

Only real downside is needing to keep it charged. But that doesn't take much and I do it every 6 months.

Honestly, I can't even remember the last time my truck needed a jump. Of course I put a new battery in before the old one fails.

 

Shows only 525 cranking amps on the specs….I don’t think that’s enough. My 750 cranking amp jump starter barely jumps our Tundra.

 

Ultimately it is a battery - that will need replacing some day and it is Pricey. So as others said why not get a 'normal' batt putting it under hood with a batt charger relay? Less than half the price with a less expensive batt to replace someday - just a thought.

 

Good idea but damn, 4 bills is alot.

 

What jump box is that? I haven’t seen one that small that can handle a V8. The one I’m using is one of those Costco multi function jumpers / air inflater / etc. It isn’t terribly big, I’m just tired of things either floating around the truck bed or taking up space I need back there for other stuff.

It happens. Like if I stupidly forget to turn off the Matt Gecko LED lights in the truck bed. That’ll drain out the battery overnight. And while I haven’t had it happen, I go away for weeks even a couple months at a time and leave the truck sitting in an airport lot or somewhere unused. Battery has never failed to start. But it’s a be prepared thing. Just my thoughts. Everyone’s mileage varies.

Leaving the truck sit for a long time, and wanting to come back and have a backup is pretty strong justification for a jump box

 

I have one of these in each of our vehicles. They have never failed to jump, even big V8s.

As a prepper, I understand. But $400 for something that can only work on your vehicle and then might also be dead since it could not be charged for weeks or months, is a waste to me.

 

Just stumbled upon this thread while showing my friend this power system. I've had one in my car for a few years now. I wouldn't be worried about the 525 cold cranking amps. How this actually works is when the voxx powers on it activates an internal battery warmer then juices up your battery before a bit before saying it's ready to jump. As long as your battery is good and can take a charge it will start your truck. I actually added an anderson power connector to mine and made a detachable set of jumper cables so I can remove it from my car and help someone else if they need a jump.

 

Get the NOCO GB 40.

 

Found this...it came out 3 years ago........

Might consider a super capacitor jump box. Just another option. Cheaper, you don't have to keep it charged and it is a lot less complex I think.
