How much capacity are you looking for ? Did you check Robu.in ?

I am looking at around 30Ah of capacity, preferably 3ah+ per cell. and yeah robu.in is quite expensive for dense cells. It should be much cheaper to extract cells from right power bank.

I have only bought cheap 18650s from makerbazar.in for small projects but for a high capacity battery pack, I personally would prefer a LiFePO4 based battery pack like this:

CAML 30 Ah / 385 Watt hour Lithium Battery for Home Lighting System

Buy 30 Ah / 385-watt hour lithium battery for running dc loads, fans, bulbs, and mobile charging. It is zero maintenance & long-lasting product. Lithium battery comes with safety, compact size, cost reduction, and high charging speed. this battery is used in many government projects across India.

This is supposed to be quite compact for the offered capacity and good quality with warranty as well.

Powerbanks these days come with lipo batteries, I bought a couple of tp link power banks on some website for cheap which had good quality 2600mah LG batteries , not sure if u can still find them though
