I haven't had very good experience with Electro and Co. I bought an EMXRON controller kit (votol) for my sur ron light bee after racing against them during Hot August Pitbike Nationals MX race. Took a while to get it. Wasn't 100% how I wanted it. I wanted to pair with a QS165 motor but they say they can't do it. The performance and features were mediocre compared to my old BAC4000 controller kit. I killed the controller and stock motor the first race and 2nd time I rode it. It couldn't handle an enduro. Austin from E&C seemed like a cool guy until it broke then completely stopped texting me. Didn't take care of me at all. I sent it back and got a hold of Kevin and for them to test the controller out because my bike didn't work anymore. After a couple weeks they had supposedly tested the controller and it checked out fine. I bought the kit for close to $900 and they lowered the price to around $500 so I immediately loose money on it and can't sell it. This year i managed to sell it on ebay at a loss and the buyer said it didn't work. So frustratingly i have to refund it and take that garbage back. I can't test it because i don't have a stock motor anymore. It was suppose to test good who am I to believe tge buyer or e&c? So I give up and take the $900 loss. So my Electro & Co experience has been awful. The Votol controller cost is around $200-$300 and the kit was like close $900 where does the extra $600ish go a buncha brackets and wire harness? Not a very good company at all. Will make a separate thread about this. I went with KO Technologies KOMoto motor and controller in the end and couldn't be more happier. My bike has completed many races (as opposed to 1 the E&C couldn't complete) and been on the podium many times as a result.
