Only the battery packaging is different where E2O uses the prismatic cells while Nexon uses cylindrical cells.

Mahindra battery price quote is insane. Granted I do not know what brand the cells they use and well known brand cells will cost more.

But a generic LFP pack of prismatic cells of roughly 10kw will cost 1.5lakh inc gst(2019 price in Bangalore). The price is end user price without the BMS and it won't cost more then 20k for the BMS. But in your case the car already has a BMS, so no extra cost for it.

How many kms or charge discharge cycles your E2O car has done and what is the current range.

Rs.7,47,641.00/-. This is the price on Boodmo.

But then you won't need to replace the entire pack. Only the cells that are bad. And for sure some cells will go bad before 8 years which will be replaced free by Tata.

The whole battery pack will be replaced because if they choose to replace only few cells then it will cause major imbalance in the cells of the pack.
Secondly, it will be a big challenge to re-seal the battery pack to retain its water resistance or the IP certification. Dealers won’t be able to do it and Tata can’t take the risk of leaving such important component of the car vulnerable.

Tesla has replaced battery packs on certain cars recently that were under warranty but had started to degrade significantly or were not able to hold the charge. Regardless replacing the pack is the way to go as its more cost effective.
Take it like your inverter or 12V auxiliary car battery, when they go bad they are replaced, it will be too much of a pain if we had to get them opened and repaired. Not worth the time.

This was the information given to us by someone from the technical team at Tata. The dealer connected us directly to him and he explained that only faulty cells will be replaced and not the entire pack.

I will take that information with grain of salt. You should ask him to send you a breakdown of cost on email for future reference. Even the higher ups at Tata EV division are staying mum about battery related cost, so for the person to say that cells can be replaced is misleading. I will recommend not to make a buying decision based on that information.
