Mine arrived promptly. Thanks for fitting 4mm gold bullets Wayne, i wish i could solder connectors so neatly!
Just checked the ir on the cells of two packs, both are 4s 2650mAh Thunder Power Pro Power 45C, which have about 90 cycles on each, both bought early this summer on the same day and used in a 3dhs Aspera and 3dhs 51" A J Slick.
At ~21 deg c (~70 f) rounding to 1dp one pack cells are 5.8, 5.8, 5.8, 5.8
The other is 6.2, 6.2, 6.2, 6.2

Neither pack has been used for 3 weeks, both were storage charged to 3.95v on a hyperion duo and cool stored. voltage today is very well matched for the cells in both packs
