I'm looking to add a shunt that I can know the actual capacity of my batteries. My BMS (jbd) always resets to 120ah if I don't connect to bluetooth 100% for >24hrs. I know the JBD isn't reliable, so everytime I get in my van, the SOC is a crapshoot. I don't use the batterybut about 130hrs/mon so...

As title states, I currently have a 40amp breaker (tube style Anoshi brand) and it is now breaking instantly. I read elsewhere these style are crap. I'm looking at the square kind, but there are many brands. The one I have also comes in square, but want to ensure I'm buying a good breaker style...

My battery is now installed in my van, but I want to add a layer of protection between the terminals and my lid and anything shorting the sides. I was thinking of getting 1/8" plexi and heat bending it as a "hat" over my cell pack and screwed to the wood compression slats. My three questions...

So my BMS did something weird last night. It is NOT plugged into any charging source and only drawing about 4amps at max when my truckfridge turns on. Opened app this morning and the capacity launched to full and also zero current draw after around 11pm. Bummed because I wanted to try and drain...

Finally got my battery, renogy and fuse panel all setup. HUGE thanks to Gazoo, Just John, smoothjoey and others for shepherding me along and answering my dumb questions! 120ah wedged under my driver's seat. Had one spark when attaching my ground but that's because I forgot to turn off my BMS...

When I download the apk info from Will's website, it downloads as a zip file and when unpacked there is no install apk. I've installed dozens of apk from chrome download. If his install broke? https://www.mobile-solarpower.com/raw-lifepo4-deals-page-676969.html

So...since my battery setup did not come with bus bars, terminal screws and nuts, where can I source these? I have no idea what size bar I would need...all I know is they state M6 terminals. 120ah 12v LiFePo4 system from Ninthcit AliExpress. This is their response when I asked why I hadn't...

My batteries arrived (without the busbars, studs/nuts ?) and the voltages were IDENTICAL at 3.293 across all 4. The terminals all looked clean and threads looked good. 2 of the cells had some swell to them, Ninthcit says these images are normal, but not sure if I'd agree. Going to be used in a...

I'm looking to explore a permanent solar panel on roof and a 100w briefcase panel to chase the sun vs moving MY van. I have the SAE hookup oultet on side of van that has 10awg wire running to where my DCC30S will live. That DCC30S will power 120ah of LiFePo4 goodness. However, when I look to...

I am looking to finalize all my needs before purchasing, but there are so many different schematics that I'm not sure which to follow... I've seen very basic Solar setups and not all these circuit breakers all over the place and ones with circuit breakers on every single hot/load wire... Does...

Looking to place my AliExpress order and debating these two packs/sellers. Which one would you feel better in buying? I'm leaning grade A and maybe saving over $100 to wait a few months and choose ship from China vs. us. I'm in CA and not in a MASSIVE rush to get rolling. Are Grade A really...
