    Heltec (JK) 200A Smart BMS with 2A Active Balance

    It's on this site in resources, and on the github page in at least two locations: https://github.com/jblance/mpp-solar https://github.com/syssi/esphome-jk-bms/tree/main/components/jk_bms

    JK (JiKong) BMS - 4S

    Yep - that's why I ordered a new BMS as well to go with it. I have a thread where I'll post the results once I have them. Any day now...

    LiFePO4 heating pad for cold temperatures

    The Aurora there is awesome though.

    LiFePO4 heating pad for cold temperatures

    Not a lot. Mostly twilight with maybe an hour or two of sun at the horizon, but it's getting better every day. We've had (and still have) a ton of snow though, so most of the times what little sun there would be was hidden behind clouds. We had a very long cold streak with -20C and below for...

    He's in Svalbard :) That's even very north for a Norwegian!

    JK (JiKong) BMS - 4S

    Quick view of the battery status without having to pop your phone out. Usually I don't have my phone with me, or I have gloves, or my hands are dirty, or forgot the phone again.... I'll probably 3D print a custom enclosure for it and integrate it in my next box design.

    Disagreeing with a Youtuber - DC Breaker Safety Concerns

    Yes. Every time I post a link. Also comments that reference other sites get removed. For example, any comments on e.g. Andys' videos I make referencing "DIY Solar Forum", "Alibaba/Aliexpress", "Search on ..." etc. get removed automatically. Andy conformed this.

    Jk BMS on inverter current issue from the maker

    Approximate Battery Life

    My opinion: your solar array is too small. 5kW of panels (just found that in your first post) with a 19kWh battery with a 12kWh/day consumption. 19.8kWh production - 12kWh use = 7.8kWh reserve on your best day ever.

    JK BMS - rampant bullduggery with current measurement -

    It's a bit of both. I can't quickly summarize right now, but check this thread starting at the post linked: https://diysolarforum.com/threads/heltec-jk-200a-smart-bms-with-2a-active-balance.17831/page-22

    Approximate Battery Life

    How big is your solar array?

    Approximate Battery Life

    This is off topic, but it depends a lot on the temperature. 4000/6000 cycles and whatever are based on 25C operating temperature. If it's 45C, you can half that. Conversely, keeping them at cold temperatures reduces calendar aging.
