It isn't really possible with good estimation because bots (and bot ratings) don't play exactly like human players do and also because playing just a few games gives a low sample size.
The best way to estimate your rating is to simply play games in live chess and after your rating begins to stabilize around a certain rating...then that is your estimate 
Let us not forget that even ratings of players who play for years are only estimates. You are basically asking for an estimate or an estimate using only bot games as information. It would be really difficult to come up with a reasonable guess at your chess ability and get it accurately.
p.s. The game accuracy is called CAPS (Computer Aggregated Percentage Score) and without getting into too many details, it isn't that useful of a statistic as it is misinterpreted by others often:
Hello I am a new-comer in this community. I lost against Komodo12 (engine) (Elo 1600) but with an accuracy of 70.5% (it had an accuracy of 77.5%) since I have not yet played against another player, I want know if I can obtain my approximate Elo rating. Is this possible? If so, what is my approximate rating?
P.S. On other accounts I have played against the bots and won up to Antonio(1500) but I couldn't beat Isabel.
