Well I ran a Profile for the (aka my old) Samsung 25R's and the following Battery Profile is from a set + 1, same batch, batteries; the set have been paired for several; months in a Sigeli 150W Mod and the +1 from an old IPV 4 Mod. Ideally I'd much, much, prefer to use a brand new set of 25R's or any batteries. When I came home the test had completed, but I noted 3.30V, 3.35V, and a 3.41V .. that's not a 'good' example however the 3.07V test cutoff is good.  Under a 'Rated' 10A load 8.74 Wh*3 = 26.22 Wh vs 'Observed' 22.86 Wh or 3.36 Wh which is good but a new set probably would have been a tad better.

I set mine 25Rs (new) to 23.08WH  and its working good !   best regards
