    JK BMS: any alternative/3rd party (Android) apps available?

    Hi, Does anyone know if there are alternative mobile (phone) apps for the JK BMS series? Or possibly apps that can be customized with graphics and so on? With regards, Martijn

    DIY LiFePO4 Cost Analysis - The Cheap November 2023 European Edition

    In the camper I use an Victron MultiPlus 2 and when charging from the grid, the JK BMS does not have a connection with the MP2 so it cannot signal a lower charge current when the battery is nearing full SOC. I programmed some Node-RED stuff on the Victron Cerbo to lower charging current, which...

    This is what I'm interested in also.

    Yes, indeed. So far, all I've seen is the box that comes with all parts like connectivity towards BMS and the BMS included, or a bare bones, a few separators only. Price difference is quite large, but at least you can use a JK BMS with the latter ones.

    Wow, basen rack.mounts batteries destroy a home in germany

    Still makes me wonder what could have been the ignition source then. Does the MP2 produce an open spark somewhere?

    Interesting, but this also means that the gas is inside the pipes, I'll take it he didn't open up any taps in that basement and light a flame. ;)

    Given the number of panels, is there any reason to think this isn't an electric boiler instead?

    How much safer is 24v vs 48v ?

    This thing always makes me wonder -- all switches I can find, like main battery switch, are all rated to 48v, not nominal, but max. So, 56v is too much. Where do you find your materials that allow up to 60v?

    Do I really need to put cells under compression or just be able to withstand expansion?

    When using this in an RV/truck/whatever, this would worry me. Especially when using solid busbars between terminals.

    48v batt. Missing somthing?

    Personally, I would put the 2nd cable connecting both posts at the other end of the post, not with the lugs on top of each other.

    Victron CerboGX programming for decreasing amperage in charge

    Well, it seems to work so far. I posted it as a suggestion for people to read on how to throttle charging when there's no connection between BMS and Victron MultiPlus. ;)

    Crimping tool recommendations for MC4

    Here's a photo of the crimper that I have for bare connectors. Looks like the die set @HRTKD mentioned.

    Crimping tool recommendations for MC4

    Is an MC4 crimper any different from a 'normal' crimper for bare 4-6mm2 lugs/connectors/etc?
