Capacity of my lithium battary is 100ah, if it discharge 70 %,would this charger to charge battery to full capacity?

Yes, provided that your battery cells are in good condition and are able to take/hold a charge, this charger will charge it to 100%

Will this charge lithium iron batteries like Shorai?

I've been using it on my Shorai battery for about 1 year and it works Great!

Can I get it with eu plug?

We don't offer the EU plug, but it can be used with an EU plug (100-240V).

How long will it take to charge 80 as (group 27) lithium lifepo4 battery? 20 hours, or few days? thanks

Instructions say it will take 125% of the battery AH capacity for the battery to charge, so I assume you multiply your amp hours by 125% to get a rough estimate
