New battery tested, felt like super human again. Gonna order 2nd one so i could daily rotate its usage.

New Qiroll H70 battery arrived! Finally i need to replace my 4 year old H70 battery..nothing wrong still works but sag 2 LED blue bars (voltage sagging) when i ride just doesn't have that "OOmmpphh!" power like it used to recently this month. However consider this old battery have been survive...

I did manage to remove three screws but all i got was a an enclosed metal cylinder and 3x wires connected. I still dumb founded on how to open the cylinder motor as i don't see any screw enclose it. This is on PRO model. I knew the motor inside is still spinning when i stop the bike/ brake...

Another bike with Qiroll Pro (latest version) still alive after daily abuse on all weather. However it started to sound like turbine jet like the first one if i keep boosting/throttle up. I suspect the inner clutch was loose or grinding along.

My Qiroll Pro still powering good on my bike in 2026 during daily commute. No problem. Battery still runs well since my first post. Anyone still rocking Qiroll? Video:

Good to hear you enjoyed the Mute version, i have to agree Qiroll should put the LED indicator status on the controller so we could see visually see and know which modes we're riding in. Sometimes i accidentally press the regen brake/mode button and didn't realized it slowed down on fast...

My Qiroll Pro still going strong everyday. :) Video link: https://x.com/SupermotoXL/status/1977709385620054054

Yes i do tape it on top overlapping each other on the center of the friction roller which is good for extra thickness and durability.

Its MR03 connector.

Baseline for your Qiroll Pro Max is to look for 33V battery.

If the tape not wide enough you can overlap the tape side by side to increase the width like how i did it from previous post photos. About traveling with ebike battery i have no experience about it but different airline allow certain watt hour capacity which you need to check.

That's why i go PRO, great hill slayer. :)

The tape i use is about 2.5cm width fit nicely for 320W Pro but on 400W i just overlap side by side. Attached picture how i overlap the 3M friction floor tape width by 2x when wrapping on the friction roller of 400W.

I don't have the link. However i didn't use Qiroll friction tape, i just DIY 3M floor grip tape and layered twice (2x) on each side to increase the width. Works best. :) I'll post a picture how it looked like with 2x side layering on 400W tonite.

Here's my experience between 400W and 320W. 320W (QR-E PRO) Lightweight. Stealth looks because the unit smaller. Consume less power on the battery. Ideal for: Minimalist looks and lightweight build. 400W (QR-E PRO MAX) Better hill climbing power assist/Torque power. Faster acceleration...
