    New to solar. My solar charger from amazon bought two and both don’t show the solar panel charging battery. The battery is full

    I think you answered your own question. How is it supposed to charge a full battery? Drain your battery a bit and see what happens.

    280AH 4S, Compressed with Heaters in a 27 Series Battery Box

    It's a sheet of 0.040" aluminum in "Pepsi Blue". I got twice as much as I need for $4 on eBay. The heater pads are attached with RTV silicone gasket sealer to it and the battery cells sit right on top of it.

    Different voltage cells in DIY battery

    You need to top balance. Your cells are way out of line. DIY LiFePO4 101, step1.

    Did I damage my AGM battery with a low 'float' voltage?

    I agree with Short_Shot. Set your float to 12.6v. I would also wire your loads so that no loads pull from the starter battery unless the engine is running. Don't use the built-in WiFi router (or anything else) that runs off the starter battery. Add another one that runs off the house...

    280AH 4S, Compressed with Heaters in a 27 Series Battery Box

    My BMS came with the heater cables. They have an overtemp disconnect thermostat built into the cable assembly that you can see in the third picture. Yes, Thats an active balancer by the BT module. I'm not sure I need it now that I have a few good cycles on my battery. I would highly...

    280AH 4S, Compressed with Heaters in a 27 Series Battery Box

    Thank you. Aliexpress. Look for 10W Silcone heating plate. They were about $2 each with free shipping.

    Crazy low prices on Aliexpress LifePO4 320A, with buyer protection?

    My experience with this is extremely poor. It's a long story, but I was ripped off and have no recourse. There is no protection.

    BMS cut off , one unbalanced cell

    Could be a bad cell or just not balanced, but you should not have to deal with that with a commercially built battery. Contact their support and/or return it.

    New JBD / Overkill bluetooth monitor

    I just ordered a RPi 4 and ESP32 yesterday, starting down this road with Home Assistant. I was going to do just the house, but this topic might get me to do the motorhome as well. I will be following and posting if I have any success.

    280AH 4S, Compressed with Heaters in a 27 Series Battery Box

    The seller says each of the two ports can support 10 watts max. They turn on at the lower temperature charge cutoff and back off at the release value. I bench tested this to be true. I do like that built in feature. As shown, I put 2 10W silicone heating pads, one on each port, on an...

    280AH 4S, Compressed with Heaters in a 27 Series Battery Box

    B+ is to power the two heater circuits built into the board. The heaters are powered by the top two ports above the B+ marking in the pic. I don't think it's required for anything else. I like the BMS so far. No problems.

    Are there any cases that fit 4 battery cells?

    I just started a show-and-tell thread here: https://diysolarforum.com/threads/280ah-4s-compressed-with-heaters-in-a-27-series-battery-box.26901/

    280AH 4S, Compressed with Heaters in a 27 Series Battery Box

    A few pics of my 4S 280AH build with 150A JBD BMS with cell compression, Bluetooth, active balancer, and two 10W heaters all shoehorned into a marine 27 series battery box. The packing foam that the batteries came in makes great insulation and hold the battery in place.

    Are there any cases that fit 4 battery cells?

    I used a standard marine 27 series battery box for my 280AH cells with compression, 150A BMS, and two 10W heaters.
