Fuel to the fire >_> <_<
Efest, IMren, MXJO, and several others you never know what battery they have re-wrapped, could be an LG HE2 from B or C quality bin that LG themself won't put their own wrapper on, or it could be a B or C bin Panasonic NCR18650B, the LG HE2 A Bin Spec is a 20amp CDR 2500mah, the Panasonic is a 10ish amp CDR 3400 Mah, yet the purple wrapper says 3000mah 35amp CDR????
You should be fine using them in that T8, but still for the price of one of those Efest, you could have got a pair or 2 pair of the authentic A Bin cells.
Check out
@Mooch and
@Baditude 's blogs, they got a lot of good battery info to guide you on a better purchase in the future, and FYI there is no true 35amp CDR battery on the market, max CDR rated battery is a 30amp.
