Are they pure copper, or copper clad aluminum? I have seen some pretty sketchy "2awg" no name jumper cables.

Radiant emissions from a body in the 90F range are pretty minor, and you aren't fully surounding yourself with this cool surface anyways. Heat transfer will still be dominated by convection and conduction from the skin. So you will still have heat transfer to your environment via...

Stopping condensation is not possible when the dew point is above the comfortable temperature (anywhere its hot and humid). The main advantage of cooling the air, is that you are also lowering the humidity. As humans sweat to cool themselves, this improves comfort even at a higher temperature...

I was just able to cram the current sensor into the box. An interesting note about the current and voltage measurements from the BMS. The raw values are not software filtered. They vary significantly when running from the inverter, or charging from a mains charger. For example my AC unit...

Battery pack has been commissioned and is working fine. I will do a capacity test later this week, and setup the alternator charging. Gray tank i installed, and awaiting plumbing. I insulated where possible, but may add some more down the road. I may change the filler wire next time...

The USA is a signatory of the international motoring treaty. With a tourist visa you can temporarily import a vehicle you own for up to 1 year in the USA. As far as customs is concerned, is that the vehicle is legally registered in your home country. LHD/RHD, headlights, mirrors, air bags...

I got torque setup on my phone, and an OBDII to bluetooth adapter connected to the BMS. I roughed out a few gauges for the various critical PIDs. Looks like I can get all the important data. Even better, with Torque pro, I can log data directly to my phone for later review. The BMS also...

Your correct, the Orion Jr gives me full control over balancing. Right now it set to balance when any cell is over 3.25V, and bring all cells within 5mv. It will do this regardless of charge/discharge. Since my rig will be occupied full time, time above 3.4Vpc is very minor. I may go with a...

Finally got the cells balanced at 3.575V plus/mins 2mv. I shouldn't need to do that again thankfully.

Doing a commissioning charge on the pack. Put in 280AH at 120A, then dialed back the charge from 120A to 35A. Looks like I have one cell group thats higher than the other three. 3.39V vs 3.47V currently. Thats probably around 10-20% imbalance, but just guessing based on some LFP logging others...

Please do. I am sure there are plenty of curious minds who would miss it buried in my thread. ------------------ The Orion BMS uses open drain outputs to control stuff. Since the RBS uses a 12V (open source) trigger, I needed to invert the signal. I also wasn't sure if the RBS would exceed...

It depends on the BMS. Not all of them will switch the in/out FETs separately. Some will only switch them together, acting like a standard relay.

The RBS does take a normal switch input, which is what I have (it even comes with a switch). Instead of dicking around with disconnecting your solar panels, etc, I would just get a 5AH AGM battery (common for UPS, fire alarm systems etc), and wire it in parallel with your lithium bank, on...

https://www.bluesea.com/products/7700/ML-RBS_Remote_Battery_Switch_with_Manual_Control_-_12V_DC_500A I am certain a simple on/off signal is all that's required.

For all intents no current will pass to or from the battery. The latching relay can interrupt either the positive or negative feed. For ease of wiring mine switches the positive feed. The Blue SEA Remote Battery Switch has its own internal logic board. It is wired like a normal relay...

Some of the FET BMS have a small leakage current ( a few nano amps or so) when off. If there is no load, the terminals may read a volt or two. If necessary you can add a high value resistor across the output terminals, which will pull it down when the BMS is off. The BMS I am using does not...

Yes, just the bottom.

Got the shower curtain installed. Jen sourced some stainless fixture pins. These are positive retention with a release button. The curtain is a standard length XPLR Outfitters model. On the bottom there are 4 15lb magnet catches. I will sew one side to the curtain, and bond the other to...

Got the box dropped in. All the heavy wiring is done. Still need to do comm and control wiring. Plus reprogram my inverter, monitor, and solar controller. You can see the blue sea RBS, and my ACR. I am using the ACR as a standard relay though, as its voltage logic is no good for a lithium pack.

Installed the heating pad to the pack. When I removed the backing paper, I discoverd the heating element stops 1-1.5" from the edges. So I could safely trim the foam down for a better fit. A was also able to remove some material from the side with the wire entry, and relocate the wire...
