    Watching that wedding ring get close to bare wires was pretty anxity inducing.

    As an electrical engineer watching this was painful. But seeing linus ride a tiny toy car made it all worth it.

    XD I did this myself! But i used a battery monitoring system to sound an alarm with low voltage and a heads up display instead of a battery manegement system. XD and i charged it using tp4056 micro usb lithium chargers. Haha!

    Isn't electrocution more severe than a battery exploding? I'm fairly certain electrocution is death, and that scares me being the minor threat.

    10:06 haz modular battery kit with bolts, soldiers on wires..... i get it with the main connectors, those special bus bars, but seriously man, just bolt the wires in, they are sensors, they don't carry any load. and the whole idea of the system is to avoid soldiering, if you use the big bus bars with the "outputs" then sure soldier, but you didn't need your iron today.

    i made a 14s 10p battery for my electric trike i bought a battery tab welder with the money i saved diy i split the pack in 2 x 7s so i can parallel charge the 2 packs on a 10s 30a charger so i can balance charge 58.8v 30ah pack in just over 2hrs ;-)
    much better than having to trust a bms not to fail (as they often do)

    You dont need a 7s battery, because a 6s battery is around 24v when it is fully charged.

  • Krankie V
    Krankie V Month ago

    Will you stop saying that a mistake on low voltage can electrocute you? It's nearly impossible to be electrocuted with 24 volts, unless you stuck the wires into open wounds on either side of the heart or something... There's no reason to make this sound more dangerous than it is! The real danger is the risk of fire or explosions due to short circuiting these cells.

    You guys goofed this up badly. It's pretty much a video on how NOT TO wire up a DIY Lithium Battery. Electrician's gloves are the very first thing. I am not even going to go into the rest, because it's all just one giant disregard for basic safety.
