It's time for round two!
Given that:
Black has 6 pawns and a king
White has three pieces of any kind you to deduce the identity of and a king
Construct:
A legal position in which both sides help to give a legal sequence of 13 mutual checks
Positional variations are allowed. To my knowledge, there is really only one way in which this idea can be constructed. I accept alternate answers.
If you have questions, feel free to ask in the comments section below!
Good luck!
There is a slight shortcut for this puzzle if you can figure it out...

My position has a fourteenth check too, but that's probably ok. :-)
[FEN "8/8/8/8/8/4K3/2pppppp/RR4Nk w - -"]
These are the moves:
1. Nh3+ d1=N+
2. Rxd1+ cxd1=N+
3. Rxd1+ e1=R+
4. Rxe1+ f1=N+
5. Rxf1+ g1=B+
6. Rxg1+ hxg1=B+
7. Nf2+ Bxf2+
And here's the whole solution uploaded to Lichess.
EDIT: Looks like 15 is also doable:
The final check feels like such a waste of a piece though; the first fourteen checks are possible with white having only two pieces and a king:
[FEN "8/8/6Q1/8/5R2/5p2/ppp1p1p1/R3K1k1 w - -"]
1. Qb6+ f2+
2. Kd2+ b1=N+
3. Qxb1+ axb1=N+
4. Rxb1+ c1=B+
5. Rxc1+ e1=B+
6. Rxe1+ f1=N+
7. Rexf1+ gxf1=N+
8. Rxf1+
Again, here's the Lichess link.

Well, there seemed to be very few options for b to give check, so it seemed obvious that at least some of black's checks had to be promotions. -> maybe they could all be? I then managed to find a couple of ways to do just that, and one of them had an extra check at the end.
