I have 55w 30L fridge and it runs on 100Ah 12V battery for 5 days to 10% rated capacity this is real life number. With 25C degrees temperature deferential (on average ) between ambient and fridge interior. I also run it in Eco mode when on battery mode and it consumes only 2A at 13V. Your...

Yes, I use ignition wire.

You sure about 15sec? I thought there is no delay at all. I would like to have 5-10 minutes delay to give starter battery time to charge . So I don't have huge total amp draw on the vehicle alternator on start up.

I definitely won't find the thread. But you can try plugging in your bms in a power bank. Again are you sure about your red wires from bms to the cells

Get 28V charger! Take a picture of your BMS. Is it's smart one? I recently had issue with my 60Amp 4S smart BMS. Double checked wiring no issues. Until I opened my diagram and checked wiring 3rd time and "BOOM" done. So make sure you wiring is correct even if you so confident. I found on...

To 15300S

I gave up on them at that point I will use BMS to allow charging, later after car starting or just manually plug in battery. But I appreciate info you provided. Learning curve for me.

Cheap kick stand for a portable flexible solar panel. Need PVC water pipe 1/2 in, velcro tape and 3D printer. It's not going to hold high winds but will work for camping needs, very portable.

Thanks. Actually I realized my timer not working they way I want. It's only support push button.

Adding ignition delay timer to my Renogy DC-DC charger. Hopefully Renogy will improve their charges by integrating delay time in a future. Updates: stay away from this timer it's working only with trigger switch not supporting constant ignition power.

You will be using braided one? Those are nice one. I could not find them on Amazon.ca

What's wrong with flattened copper tubing? Why you don't like it? I know you can buy, but sometimes the lengths is the issue, if its not standard assembly. Or if you need to make 90degree buss bar, copper tubing comes handy. You can do nickel plating or solder plating. Grade L tubing its 99.9%...

Creality 10S proV2

Its definitely more difficult to print with PETG.

No I didn't share it. You might have a different cell size. What brand is yours? I believe my is Great Power 100Ah cells.

This is my build. All PETG used.

Moisture content you referring to it's for filament not for final product. You can actually make water containers with PETG . If you print end caps from PLA just don't try to open the caps in cold weather it will snap. Don't keep your. assembly on open sun it will twist. No, I didn't print...

It depends on your particular application. That's why I asked you the question. Personally I choose PETG because its more durable and can withstand moisture better. If I want to build something to last 10 years in dump conditions I would like to have something durable. PLA it bio plastic. It's...

There is a reason why you choose PLA? I would recommend PETG.

Works for me turning off. Turning on required breaker reset after turning on on the app, that's only one way I figured I can get it back powered.

Maybe it was hooked up to load? Do you know?

I intentionally disconnected balance leads ( no load on battery) nothing happens.

Finally finished! Took 4 months to put it together. Not Pelican case but similar Underwater Kinetics 6510. It's rebranded S3 case from US sold in Canada under UK brand. Made in US.

Look at the picture from the official brochure from ThermoKing. This is a very efficient DC electric air conditioner unit as well, condenser and evaporator are variable speed, compressor variable capacity as well. Envidia 8000 BTU . Batteries AGM 4pc 100AH @ 20Hr Nominal Capacity (Ah)...

Little more progress. Cells balanced already and installed in series. Figured it will fit Pelican 1400 series.

I just figured this on my own as well. But later noticed your post. I was able to make SOC reading more accurate than factory settings. My custom settings on the picture.

I just noticed a mistake. Bank was set to 10000mAh and I have 100000mAh when I changed this parameter to 100000mAh SOC dropped down to 10%. So unfortunately my adjustments didn't work. update: after performing a system reset via app, everything works now as I stated in my first post with the...

3.450V I just used the chart in pdf.

Just received cells. Charged them. Will have to do top balancing later. Now put them in series to design and print the holding case. Then based on the final dimensions I will have to source the Pelican style case.

SOC. After fully charged to 14.4 LiFePo4 pack blue tooth app showed 100% state of charge. But after an hour or so voltage normally equallized to 13.7V and app showing 83% which is not accurate. So I changed system voltage settings in Sinowealth BMS software to values stated in LFP VOLTAGE Chart...

At work I have really good one, got abused all the time and still running strong but I a bit pricey for home use if not using it every day. https://www.be-electronics.com/product_p/psc6932.htm

Thanks Steve you just saved me 120$ (: and tons of time!
