    The same shit everyone else has.
    No link. I ordered it a while back. There was a link for it at the bottom of the page for them at one point.

    It’s the same seller but he was selling them on eBay which made them super easy because he was selling them in USD and you could use PayPal

    i already had a larger battery i was going to use for a sound system in my old truck (kinetic hc2000) its already paid for. I have a drawer system i built and i have the room to hide my power back there. Im mainly just working with what i have right now. I have a keyline isolator, and and a blue sea fuse block back there currently maybe an inverter i have but i need to do more research in modified vs pure sin wave because mine is currently modified, but i plan on running a arb twin back there one day and maybe a fridge. so having the power right there would be nice.

    i dont have the room for another battery under my hood, i currently have my winch controller where most people mount their second battery. This project mainly stemmed from old parts that werent getting used.

    Ok, sorry in advance for this because I’ve posted about it a couple times before but didn’t get much feedback. Maybe the lack of interest is feedback in and of itself.

    I’ve been looking at these batteries:

    Www.lithiummoto.com

    What do you all think? Do they look like well-made batteries? Would this be a good option for the house battery in a dual setup? The price is acceptable to me and I do like the weight and size...

    I like the idea of lithium batteries because they have a lot more power density but not worth the added cost for me just yet.

    I don't think so.. 16ah is nothing for an aux/house battery. I guess for the size you can buy 6 of them, wire them in parallel for 96ah...but then your price would be outrageous just to almost meet the capacity of a deep cycle battery.

    So, total elementary question but what exactly does an amp hour measure? In a use case, if possible.

    Runtime of accessories. 16ah = 16 amps for an hour or 1 amp for 16hrs.

    Alright then. Another AGM it is.

    Makes me wonder what a battery with such low ah is useful for in an automotive application.

    Starting. It looks like it has a decent cranking amp rating.

    @Rujack my earlier example is a bit off.. But a decent enough generalization, granted it would take the battery to almost to fully dead which is bad for batteries.

    Thought maybe one or two of you might be interested in my new set up. Was running an OGE setup in the stock spot until the whole front fender ripped apart. Here's the new setup! It's quiet (was squeaking and creaking like crazy before, even with additional ratchet straps to hold the batteries down), my suspension works way better without the weight, and I have so much more room in the engine bay!

    Pretty neat idea. What group batteries you running?

    Were you running the side by side battery setup? What group batteries? Now you've got me scared about my setup falling apart.

    They are group 35.

    It was the side by side set up in the stock location. It worked good for a while, but after several thousand offroad kilometers, it fell apart to the point that the batteries were moving so much they severed my headlight wires and I had to ratchet straps them down.

    Once I moved the batteries to the cab, my truck drives so much better! (EDIT for accuracy) 100lbs in the front corner has a pretty big impact on handling, turns out.

    You might have better luck than me though, I do drive my truck pretty hard over bumpy roads and wheel it often

    I don't wheel very often and try not to drive too hard. I'm still concerned, but I guess there isn't much I can do about it now.

    Which batteries were you using? The two Group 35 Yellow Tops I'm running are 37lbs each.

    They are Northstar NSB-AGM35 batteries, weighing 49lbs each. I thought they were heavier, but still 100lbs in the front corner is a lot.

    You'll be fine. I had it there for 2 years before it was completely mangled

    Damn it...I am again questioning whether this is the best spot for my dual battery set up that I was planning to install this summer. This is worrisome!
