Lightweight lithium ion battery

My 270 lb muscular body type doesn't help either. Just asking general question to see if lightweight battery's are worth the money.

I understand, I have nothing but budget built stuff. I personally couldn't justify the extra money for maybe 10lbs? If this is for the car in your avatar I bet you can find that weight in other places. Just my opinion, take it as you may
