Your first lithium battery production line started in JUNE 2016, that's a month ago.

When you said BHEL made it since 2004, what exactly is 'made' in India. Is it buying Chinese lithium battery, assemble it together, add some power controller? For you to produce lithium batteries, you need to produce lithium. Can you tell me which facility produces it in India? The same goes for solar panels, you can buy Chinese cells and stick it together into one module and claim it's made in India. Can you tell me which facility in India produces high purity silicon ingot? In other words, your 'indigenous' satellite is most probably full of Chinese stuff. LOL!
If I am not mistaken, I-6K is a 6 tonner, another Indian poster said it is 1-4K, I agreed with him and suggested that certain technologies for 1-6K might be tested there.
Read my post carefully, I did mention the max your pathetic GSLV can take is 4 tonnes, which is what you repeated again before blurting out all the sh*t above. Nobody in their right minds would load a carrier up to the max, there is normally a safety factor, my guess 3.5 tonnes max for a 4 tonner?
Growth path? Another will, shall, could, would? Can't believe how fast you Indians come up with another future tense proposition. There is also a growth path for LM-9, 130 tonnes to LEO, 50 tonnes to GEO, you don't see me boasting it here. Get it done first, then you talk, see how many times your GSLV failed.
Before telling me about this super duper new advanced satellite, go check out Chinese DFH-4 which is roughly comparable spec, we had it since 2006, that's a decade ago.
Since when did I rant about your Russian copy clone 'indigenous' CE-20? Btw, cryogenic engines is almost a 40 year old technology for China and you are still testing it now? Pathetic! SUPAPOWAH MY AS*!
When you have a 6 tonner, China would have completed DFH-5, a 9 tonner. I realise there is a pattern I am seeing here, for most technologies, India is almost always a generation or more behind China, be it aircraft, space or RIFLES. I actually did not want to give a sh*t about this until you Indian BOAST again that you have the most advanced satellites in Asia.
