I've known Shreyas during our school days in Lisieux, Coimbatore. A superb basketball player and I've also known him to take crazy bicycle trips as well. It's a pleasure to know he's part of this revolutionising industry. All the best, brother! 🎉

Absolutely enjoyed the video. Shreyas explained the engineering process very well - Aluminum Casing - Space between Cells - BMS - Cell Short Circuit Conditions - Testing The Ather battery is built for abuse. Other OEM's should learn from Ather. Keep sharing these dev/tech talks!

Awesome podcast. I would request Ather team to work closely with Indian academia to develop the liquid cooling system for battery/drive. Higher power can be packed. Space can be carved out if the scooter is made a bit bigger. Currently the Ather scooter is very nimble and agile. I think there is some room for increasing its size

Have always been a fan of ather 450 when it was launched, Even better now that they are proving why ather has lot of R&D behind every aspect. No fancy features here n there but simplicity & most importantly balancing between range , battery & its capabilities. To companies who are in race learn from ather They have come long way to reach here.

Was an interesting session. Waiting for my Ather to be delivered. Have a question on the protection on the underside of the battery. What happens if the battery gets hit by a speedbreaker, odd stone on the road? I remember Tesla adding a titanium shield on the bottom, any such provisions for Ather to prevent damage/puncture from the underside?

Does anyone know which cell is Ather using. With a 3.7KW battery pack in a ather scooter and if there are 168 cells in a battery pack, it gives a each cell theoretical capacity of 22Wh. If they are using a 21700 cell with a 3.6 V nominal voltage. it comes out to be 6000mAh cell which is not possible with current technology or that I dont know of. That means they are either not using a 21700 cell or a bigger size cell. or using more than 168 cell or a smaller battery pack instead of 3.7KW. Can someone help?

Because I am thinking of getting an Ather 450X so I just wanted to see or verify whether any of the claims made on KZfaq by external channels are true or not?
