Cellman/Em3ev on ES has given a bit more on them.
33G are an EV grade cell that are produced in China by Samsung. Yes they are produced by Samsung, and we purchase from legitimate Samsung supply channels. They are supposed to have good cycle life and if charged/discharged to 4.1V/2.75V are supposed to last 8 years plus in an EV Car application (just from discussion with my contact in Samsung, don't have any data to back that up). They are ~2C continuous (6.4A) and 3C max (9.6A) rated (as stated in the spec sheet I have). Our tests indicate a capacity of 3.15Ah or more per cell with a 2.75V/cell LVC in a finished pack (spec sheet states 3.15Ah typical capacity, to 2.5V LVC, not 3.3Ah as some try to market them), we rate them as 3.1Ah per cell and the discharge test for each battery is included with the battery. IMPE, they actually run a bit cooler than the higher capacity cells, when ran at the same discharge rate. The 6P pack we offer is comfortable at the (conservative) discharge rates we recommend (1.5C continuous, 2C burst). 1.5C on the 6P pack is ~28A, so if you keep the max to no more than that, the pack will not be stressed.
For info, the 35E cell has never been in mass production (according to my sources), and only relatively small quantities have been produced up until now. The 35E are due to hopefully going into mass production in the near future with a revised formulation.
