Funny enough my next plan was actually to do just that; add an additional battery for increased range or double voltage. I have a feeling the motor won't be able to handle 72 volts though, so the range increase is probably the best option. It will also help with voltage sag as I ride. Not sure where it will be mounted though, it's a big battery. I have tested out a Spin scooter the other day and first noticed how quiet the thing ran. These Chinese controllers could definitely use some redesign as far as the waveform they output. I kinda want to grab a ES4 based scooter and hack it then compare the 1000w bird to the hacked ES4 with the controller it came with. The one i test drove had a surprising amount of torque, way more than the bird with the 350w setup. This makes me think these Chinese controllers are pretty inefficient, losing a lot of power as noise and heat. I can't find any full threads on the process of hacking an ES4/ES3/etc based scooter though.
Also there's no way in hell he hacked a bird using stock parts, and even if he did the top speed would probably be limited to 15mph as that's built into the bird system. We out here pulling 23 on the hacked models
I have 4 hacked ES4s they work, i made one and the weird thing is the stock motherboard blew but all others are completely fine , which I thought was weird... I made one for my GF and it still works fine not a problem, I used aftermarket parts on jers and it links to the segway app but you cant install updated firmware which isn't a issue l, the only thing cool really is cruise control on the app.
The bird zero scooter is harder to crack but I'm going to wire up the control board and throttle, theirs 1000 different set ups with every possibility but for now that's the most efficient way, I'll post step by step pictures on how to do so once they get here
I'm ordering off of ali Express because amazon taxes way more than ali since is US based, plus their refund policy is pretty legit
Stay tuned guys
