February 15, 20179 yr Mmmmmmm, Nealh appears to be correct. Can't seem to find any spec sheets for the 33g

February 15, 20179 yr Mysterious. Do they even exist? Sent using this crappy tapatalk app. that has such poor functionality I can't even click 'like'! Yeah, Alibaba selling them, doesn't inspire confidence that they are genuine. Although, I wouldn't have thougt Lunacycle would have been roped into selling a scam battery pack.

Although, I wouldn't have thougt Lunacycle would have been roped into selling a scam battery pack. My thoughts entirely. 1-4 bucks each aint right either, surely? It's an odd one. I'm looking to spec up some new packs and intrigued by the prospect of them. Will likely stick to the old tried and tested.

May 3, 20178 yr Only seen limited specs nothing special. Std unprotected 3.6v nom/ 4.2v max cell with 7a max discharge per cell, weight 45 grams and 3300mah. Not a game changer just another middling cell ok in 5p format or more , though not seen any test reviews for them yet. EM3 and Luna both using them. Edited May 3, 20178 yr by Nealh
May 4, 20178 yr I got told by EM3 that it's an automotive grade cell and that the info they have is confidential. They are supposedly rated for 2C but they recommend 1.5C.
May 19, 20178 yr 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.
November 23, 20178 yr 33G celled battery here if anyone is interested but performance wise not as good as the 29E and only marginally slightly better capacity as mentioned by Cellman. https://www.ebay.co.uk/itm/Down-Tube-Bottle-36V16-5Ah-611Wh-Lithium-ion-E-bike-Battery-Black-USB-3ACharger/302459538377?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649
