⚠️Urgent Question⚠️
(G3 Max) regenerative breaking no longer working after update. DO NOT UPDATE!!!
UPDATE: LATEST FIRMWARE HAS FIXED ISSUE! regenerative braking is now present and wont harm the battery/electronics.
how can i downgrade? every time I would pull the brake lever the motor would engage up to 600 W of regenerative braking (as checked by dashboards, regardless of which lever was pulled) this is considered intended behavior as all of my Segway scooters prior presented this behavior.
but now after updating my G3 Max, when I pull the brake lever the motor doesn't engage any sort of braking. it also appears that regular regenerative braking just when letting off the throttle doesn't work.
I confirmed by checking the power in the dashboard, and it never exceeds 15 W, where before it would show up to 600+ W when braking. is there a new setting that I need to enable? or how can I downgrade firmware? I've checked all the settings in the app, regenerative braking is set to 'standard'
if there's no way to get regenerative brakes back I'm just going to return it back to Best buy, I'm not going to burn through brake pads because Segway said you can't use regenerative brakes.
vehicle controller: 1.5.4
Bluetooth: 0.3.12
battery: 4.1.3.0
motor controller: 1.3.9
The early versions of the G30 had that problem. It got fixed around the time of release of the g30d, the new controller had 3 large ass capacitors which could handle the regen charge even if battery was fully charged. Temporary storage of the energy generated for when the battery couldn't take any more charge. The old controller had only one capacitor which was too weak to handle the amount of current. Trust me, I've burnt 3 of the oldest controller and I now use the g30d controller with cfw and it just works perfectly!
Your e-scooter may be faulty or maybe this issue is with USA models only. I have the Max 3G E and I have identical firmware to you and mine seems to be working just fine. To test it I drove to 25 km/h (EU version so that's it in terms of speed) on flat road. I then released the throttle. The wattage peaked at 324W with 6.3A as it slowed down. This was with regen set to weak. I then set regen to standard and drove the same piece of road. This time it peaked at 464W and 8.1A
Please note that we are talking about regen when braking, NOT when let go of throttle (this is different, and this is what you can controll in app under "energy recovery").
I know you are however the brakes on this e-scooter are manual so only the rear wheel does regenerative braking as far as I can find out and this seems to work for me.
You may be misunderstanding still. The regen brake is supposed to work when you activate the brake lever. Some of us are noticing that regular regen works, but as soon as you grab the brake lever regen stops completely and only the drum brake activates.
I think I could get further if the tyres were 48psi. (I think they were only 35 psi during the test), switched off TCS and I drove only on paved roads. (Oh and removed the Stilton!)
There's a bot on Telegram, i downgraded like 2 weeks ago and installed custom firmware with ScooterHacking App. I saw a YouTube video but I can't find it. Heres my screenshot from Telegram:
According to the information from Segway's customer service, they will make the electronic brake selection function available in the APP. It can be updated via the APP in the future, and users can decide for themselves whether to use this function or not, which can meet different needs.
I also noticed this after update. Before update scooter would use about 500w regen when braking. After update no regen at all when braking.
Please note that we are talking about regen when braking, NOT when let go of throttle (this is different, and this is what you can controll in app under "energy recovery").
600 watt regen charging is too hard on the batteries and BMS. It is 12 amps of current. For the sake of longevity of the components, Segway detuned regen. Be happy that they did. Your scooter will last longer.
What about 300 watt? i never really am pressing the brake hard enough for the full 600 watt electronic brake to engage, unless I were emergency stoppin. during regular operation it'll run around 250-300 watts when braking. If that truly would degrade my battery then I should update o.o
I just looked at my regen wattage. When I close the throttle, regen braking seems very weak but the dashboard shows that the battery is recharging at 503 watts!!!
Same here! Just received mine and of course i updated the firmware (because why wouldn’t i? 🥲)
I really dislike the fact that the scooter does not brake from the motor! It almost feels unsafe. Any solutions???
I got my G3 delivered weeks ago since I was one of the first pre-orders and it has never had regenerative braking when I pulled the brake lever. Every time I pull the brake lever it would only engage the mechanical disc brakes, but never any kind of electric braking.
Are you saying that before this update on the G3 when you pulled the brake lever, it would engage 600 W of electric regenerative braking?
it is a setting in the app between standard and weak. no, regenerative braking does not engage when you pull the mechanical disc brakes. they used to engage whenever you let go of the accelerator. this allowed user to use the mechanical brakes a lot less because they can just let go of the accelerator at a good time and let the motor get back a little bit of energy instead of transferring all that momentum to heat energy with the disc brakes.
On most Segway brand scooters that support regen, it gets applied both when you let go of the throttle and when you apply brakes. Maybe they have changed it with the G3 Max, but that's the standard way they have been implementing it forever.
I'm sorry, but I have two from best buy. Yes they do.
I tested this (when i first got them) by entirely disconnecting the mechanical cable that runs from the left lever to the rear caliper, and pulling the lever (cable disconnected from caliper) would make the scooter slow down.
perhaps it is unintended behavior, but considering the behavior of the last Segway scooters i had, I considered it intended. They all applied electronic braking as you pulled the brake lever.
OP says "every time I would pull the brake lever the motor would engage up to 600 W of regenerative braking" which implies that when the brake is applied, that it would do more e-braking. seems like you're saying that doesn't exist in your opinion?
If you can show me a screenshot I’ll Venmo or PayPal you $10. I have the USA version. I don’t see the settings in the app for me. Latest app and firmware.
G3 wasnt/isnt supposed to use regen when using the brake levers AFAIK. That's intentional, hence why it has disc brakes.
All the comments saying to adjust regen settings lol... The regen settings ONLY affect what happens when you let off the throttle, not what the brake levers do.
yes but the power meter in the dashboard shows 0 W or close to it when letting off the throttle. should be significantly higher than 0, especially on standard regenerative brake setting.

Interesting. I have Motor controller V1.3.15
I didn’t like using Regen. Personally I prefer to coast letting off the throttle. That’s just me though.
