    Calculating Wire Length/Size with Van Chassis Ground

    Thanks John. You're right of course. I just thought the resistance difference of the two sources would have the house battery supplying the inverter. I'll have to look at the cabling closer!

    Calculating Wire Length/Size with Van Chassis Ground

    Chrisski & John, Thanks. Chrisski noted the inverter, but if you look at the drawing the inverter is served by the house battery which will be less than 4ft from the inverter. This connection will be charging from the alternator (190A) only. The only way to terminate to a chassis ground is to...

    Calculating Wire Length/Size with Van Chassis Ground

    Chrisski, it would mean just adding ~$120 negative cable cost? The house battery negative is currently chassis grounded. That circuit is just for charging the house battery. Other than extra voltage drop associated with the chassis ground, anything I need to worry about?

    Calculating Wire Length/Size with Van Chassis Ground

    Yeah. Great resource. I found his site while searching for answers to my question.

    Calculating Wire Length/Size with Van Chassis Ground

    John, Thanks. Yes, I expected chassis resistance was different. Battery/alternator cables are 4 awg. I wasn't planning to upgrade those. I'm expecting 50A max (25 amps standard) from the alternator.

    Calculating Wire Length/Size with Van Chassis Ground

    AHTrimble, Thanks. I had done as you recommend (and thus the larger wire size.) Yep, I have the explorist site up! It called for 1/0, so I was planning 2/0 on the positive and negative sides of the path.

    Calculating Wire Length/Size with Van Chassis Ground

    Hi, I'm relocating a house battery to inside the living area of the van in anticipation of upgrading to LiFePO4 battery w/dc-dc charger later. Primary charging will be from the alternator with small solar as secondary. Wire size calculators are looking for the round trip (RT) distance. The...

    Sold - Renogy 2000 Watt 12V Inverter/Charger R-INVT-PCL1-20111S

    I am actually in Penn Valley (near Grass Valley) but could meet you somewhere in between. Could you get to Auburn or down the hill a bit? It would be great to have someone use it.

    Sold - Renogy 2000 Watt 12V Inverter/Charger R-INVT-PCL1-20111S

    Hi, I purchased a Renogy 2000 Watt inverter/charger in 2020. I planned to install it in my R-Pod when I completed the LFP battery build. Well, I completed that and realized that I don't need the Inv/Chgr. Propane and 12VDC are all we really need. It was never installed. Just tested in the...

    Sold: 18 EVE 280AH Used Cells - Penn Valley, Ca

    I have 16 EVE 280AH cells (plus two spares) from my golf cart. They are in great shape. Charged to 3.5V and discharged to 3.0V. Cart draws 65A-70A normally and 150A up hills. I have to remove them so I can sell the cart - we're moving and can't take the cart. Asking $35 each OBO. I'm just...

    Chargery BMS Cell Readings Inaccuracy. Should I be concerned?

    I purchased another BMS16T as I couldn't get Jason to acknowledge it was a BMS problem. Jason said he was giving me a discount but I wound up paying $30 less for just the main unit and the balancing leads. Don't think that was a discount. Here are the readings (8/21 is the new BMS): Cell BMS...

    Threaded rod cell strapping and assembly

    They a re EVE 280AH cells. They are available through a number of sources, many of which are discussed on the forum. They are much more capacity than I needed. 200AH cell would have still been more than my Trojan batteries provided.

    Threaded rod cell strapping and assembly

    Yes, I did build the battery. I had six 8V Trojan batteries before. The built-in charger killed them, so I decided it was time to go LiFePo4. Measure, then measure again a couple of times to make sure the pack will fit in the space. You may also have to do some minor adjustments to the battery...

    Threaded rod cell strapping and assembly

    Someone recommended tile spacers and placing them at each corner and in the middle of the side of the cell. I used Troxell Horseshoe Shims 1/8" https://troxellusa.com/spacers-ts-shims-wedges/wedges-shims/1-8-horseshoe-shim-red-150-jar/ I made sure the U shape was up, so heat would not get trapped.
