viprit Posted March 1, 2019 Share Posted March 1, 2019 Hi, I've been using an ES2 with the ES4 Battery upgrade since around January 9th, the app says that I've clocked up 193 miles of use. This morning I had two unexpected cut outs where the power just died and the scooter switched off. The first was on level ground, the second was going down a short hill that I normally travel down with acceleration off and my heel on the rear brake.

Nick McCutcheon Posted March 2, 2019 Share Posted March 2, 2019 Did you notice it beeping at all? Apparently it will shut off if you try going down a hill/regen braking at 100% battery charge, to prevent overcharging the battery. It usually beeps like crazy to warn you of this though. If not, I guess I might be worth disassembling/taking a look at the main board and/or control board. But take my advice with a grain of salt, all my knowledge comes from taking apart an es1 and one of those auction es4 bird scooters completely.. And online research.
