They sell kill switches or dead cables i would call these. I have photo proof they wired the cable wrong and connecting it to my 1/24th scale crawler furitek esc, smoke from the wire, smoke from my esc (fried) and battery puffed up almost exploding which could’ve caught my garage on fire. Battery is garbage after soaking in salt water now for safety and esc is a loss. They wont hold up to a refund even for cable and claim i didn’t check polarity on a new cable from them backwards made.
