    External connectors for a LiFePO4 battery box (anderson, XT-60)?

    I'll just throw in that I hated powerpoles until I bought a crimp tool. I only had one connection to make and wanted a good alternative to MC4 connectors with solar panels. Following a suggestion here I bought powerpoles and proceeded to screw up quite a few times using common stripper/crimp...

    DIY Lithium Packs, Proposal and Discussion

    Shoo, I have 3 Dalys sitting around now that I swapped out in favor of chinese smart bms units. No problems now for almost a year on my 200+ah lifepo4 job running a 60a bms in negative and 110*F+ temps. Low/high cell/pack cutoff works great as does low temp disconnect. Tracks capacity just...

    External connectors for a LiFePO4 battery box (anderson, XT-60)?

    I regret doing XT60 because of the limited availability of panel mount connectors. It made sense with all of my hobby chargers being XT60, but it would have made more sense to just build an XT60->Anderson cable in a couple of minutes. You can buy XT60 packages with boots on the back but your...

    Battery Monitors, what works and doesn't

    Truly a hell of a lot better than guessing on LEDs. The less I care about mine the better. It doesn't seem to do well at all with my wireless USB/battery(18650) travel router connected via USB (12v->5v step down) and shows a 0w->3-6w->0w drain, value changing every few seconds. I don't really...

    Looking for input, opinions. Want to add solar and fridge to ATC Bobcat

    I'd eliminate the 2-4 hours each way of driving from the equation if you're stationary for 4 days. You'll arrive full and it doesn't really matter what you leave at when the trip is over, you can recharge the rest of the way at home (or parked via solar, not camped out using furnace/opening...

    Looking for input - removable LiFePO4 solution with alternator/solar charging

    Sounds like you would be using the 36ah 3.7v power bank separately then? I do that with my lifepo4 portables. Charge with solar or vehicle and use a 100w USB-PD charger to charge other power banks (45w in), or my macbook (87w or whatever max in), same thing in my mind. Use the smaller power...

    Stacking FrontRunner wolf packs

    Not bad, thanks for the idea. Some obstacles to overcome, like finding something that can actually fit through the anchors, and a bungee that isn't too stretchy. I plan to just double stack the rear/left most in pic two bins (recovery crap in one, tools and electronics repair stuff in the...

    Stacking FrontRunner wolf packs

    Quick question, but how are people strapping these down while also stacking them? I have them on a bed slide and can anchor them to the rails on the sides and down the middle of the platform, but running any strap over top of a bin means nothing can stack on top of it. Thinking about using...

    Low voltage shutoff protection

    You could get the Victron BatteryProtect 65a "smart" version for $60 and set a custom shutoff point. And also have a way to view your battery voltage whether the fridge is running or not on your phone via bluetooth. (er yea like IdaSHO said)

    How much extra fuel do you take?

    3 gallon rotopax for generator or giving someone else who ran out of fuel. I'd still buy gas in the last podunk town even if it were a buck more a gallon, before heading out in to the void. 33 gallon tank. If I didn't have over $100 in to this (can, mount) I'd probably just leave it at home.

    Solar panel under performing.

    zamp on my camper is worthless. even pumping 5 amps through it results in crazy high voltage readings. AKA victron mppt reads 14.3v @ 5 amps charge current through zamp, but reads 13.5v if connect charger to the battery and charge at 5 amps. Maybe part of your problem.

    flexible PV mounting on corrugated aluminium roofing sheet

    I'd consider the fact that the very nature of flexible panels will lead to cracking and failing. And how you'd go about feeling confident with a flexible panel mounted to an uneven surface held down only by the 4 or whatever grommets the panel has. I don't know that I'd mount flexibles with an...

    Who wants to build their own storage bank?

    For those with the funds, these seem to be the best bang for buck with plenty of capacity tests. And if you can wait for the slow boat. https://diysolarforum.com/threads/xuba-electronics-deal-280ah-lifepo4-cells-purchase-review.3850/

    Android Head Unit Solar App

    I couldn't get the Victron app to work on the android based touch screen I installed in my truck. Despite it having bluetooth, it appears to not work for everything.. maybe just audio streaming. Not really a drag though, I have a raspberry pi in my diy lithium aux battery box and router which...

    Goal Zero Nomad 100...charge car battery?

    Yeah zamp SAE plugs are reversed. You can find things on amazon to flip that the other way. An 8mm to zamp product should do that automatically. What are you going to do for charge controller though? I'm not familiar with any camper that has a zamp plug and a charge controller built in...

    Power distribution & DC-DC charging in truck bed... and bed slide

    I'm going to DIY something like this and see how it works out. I'm ok with the entire right side of my bed being a no-stacking zone to not hit the wires. It's pretty much off limits anyway with bed slide limitations...

    Headlamps

    You can get ones with adjustable beam but they do seem to be bulkier. I don't know what's up with the trend of making headlamps look like some Batman gadget though. 18650 battery headlamps, flashlights, and lanterns are all where it's at. Better if you get one with USB charging port for...

    Power distribution & DC-DC charging in truck bed... and bed slide

    Ah, understood. Hopefully I cleared things up re: circuit panel placement. I had re-typed my post 3x trying to cut to the chase and not end up with a TL;DR wall of text. Should have bulleted what I already had functioning properly and what I was hoping to add. Looking in to building a...

    Power distribution & DC-DC charging in truck bed... and bed slide

    Damn, you guys got more in the weeds than I am. @SquirrelZ I'm planning for 18 amps to be the usual. I assure you the product exists ;) and anything else powered from that 8 gauge wire will be minor, like 3 amps of LED lights likely not run in conjunction with the vehicle anyway (meaning the...
