    Overkill BMS - cell voltages flash red and grey when under load

    See video of what happens when running under moderate load at this link: The pack voltage stays constant, but each cell voltage appears to jump around by around 0.02v according to the app but using my (admittedly terrible & cheap) multimeter it shows constant voltages. My multimeter only goes...

    What can be powered with 18ga stranded wire?

    I ordered some 2/0 stranded wire and received 18 awg wire instead. The company told me to just keep the 18ga wire rather than ship it back, so now I'm wondering what can even be powered by such a tiny wire? I have a computer fan + pwm controller I'll be using this with now since voltage drop is...

    How to fuse inverter + dc load fuse box?

    I have a 12v lifepo4 battery with a 1500w inverter and various dc loads (fridge, lights, phone/laptop charging, misc outlets). I was thinking the best way to wire it up is to have one line directly from the battery to the inverter with a bolt on fuse, then another wire going from the battery to...

    First time charging battery, BMS didn't cut off charge properly. Is this cell now dead?

    I received 4x 280ah eve cells and am using the overkillsolar 120a 4s bms. I have the bms paramaters set to cut off at a per cell voltage of 3.65 and pack voltage of 14.6. I received all my cells awhile back but had some supply issues getting the bms, so I waited almost 2 months before beginning...

    How to use threaded rod & plywood to create a clamping battery box for prismatic cells?

    So i've seen lots of pictures and recommendations of people using threaded rod & plywood to clamp their cells. I'm making a 4s battery with the 280ah eve cells now and am having trouble figuring out how actually build the dang thing with threaded rod (which i've never used before) I have...

    Recommended steps to test lifepo4 cells for diy build?

    I'm receiving my 4 cells next week from a recent group buy and am making sure I am ready for the next steps. Once they are received the first thing to do is to balance the batteries, then capacity test them, correct? What items are needed for these activities? For balancing, all that is needed...

    Not sure what size BMS for newly purchased 280ah batteries

    I joined in on a group buy for the 280ah eve cells but have been putting off buying a BMS as I'm quite new and keep getting overwhelmed when trying to figure it out. I will have a 4s 12v system and am planning on having a 1500w inverter. Outside of the inverter, the loads would be a 12v fridge...
