  • the easy way to keep your cells balanced is...active balancing

    so I have some aliexpress express cells and of course even after top balancing they quickly like to get out of balance... neither the daly or overkill solar BMS in "balance" mode does anything useful. with cells out of balance by about 130mv I let the bms do its balance thing for a few days...
  • wonderful battery purchase with Excellent packaging!!

    order enough eve 280Ah cells for another 24v pack from @Amy Zheng and the packaging was fantastic!!! They did not try to overpack a box with a bunch of cells and see how much tossing they can withstand; just 2 cells per box, very well packaged in perfect fit foam shells; boxes nicely taped up...

    finally after months of searching I found "real" pure nickel 32650/32700 (4P)spot weld strips.

  • daly smart BMS balancing is a mystery novel, has anyone solved this?

    I have the daly smart bms 8s, 100amp plugged into the computer and the program is showing me what is going on(or so I thought). I was charging the 8S pack at 18amps, cell high voltage set to 3.6, low set to 3.0, balance set to start at 3.5v...all seems well. So I leave it for an hour, come back...
  • just noticed that jbd bms software "needs" gps and location access to run?

    I am moving some items to a no-wifi android tablet(no internet, just bluetooth) and the software would not install without access to my location and android location services enabled. Are there any version of this that run standalone and do not need "location" services??? "or is that a...
  • overkillsolar bms with terminal blocks is nice, so, where can I get those terminals?

    All my other BMS units before discovering overkillsolar just have the cables soldered in. Now that I have gotten a BMS with the terminal blocks, well, I like them and want to switch over; probably a nightmare to solder hehe I Looked on amazon and ebay and did not find these M6 terminal blocks...
