Just got myself a S2+ Nichia 219C 4*7135(1400mA) and some Samsung 18650 29E gen7s. I am going to get a S21a SST40 and it draws approximately 6A. Is this rating the equivalent of the max continuous or max peak current rating on the battery? I suppose my batteries can supply 5A continuous and 8.25A peak. Can I use batteries in their max peak current if I don’t let them overheat? Can I use this battery or should I get some Samsung 30Qs? Thanks.
Yes, and you don’t really have to worry about it either. Your battery will never overheat since your light will likely step down due to temperature before 60C.
Also, if your battery heats up too much it should also step down but this rarely happens unless the cell is of bad quality and has high internal resistance.
Welcome to BLF by the way
Please enjoy your time here, Torik61!
Thanks mate. I’m only a week into the flashlight community and just ordered my 2. Flashlight and accessories to go with them. I’m definitely enjoying my time but my girlfriend/mother won’t I think. Take care.
I hope that means they’re two different people 
The cell your listing is just speced under what the driver wants. Go with a good 10amp cell, less stress on the battery. Samsung 30Q would do well. Welcome aboard.
Yeah, I didn’t want to be the one to say it. :laughing:
They are 
Can I get away with my 29E gen7s for a few cycles? I really don’t have time to go to my local supplier and I’m not able to get them online. What does peak current mean BTW, is it dangerous if I use my batteries at their peak amps? I know this will shorten their life but it shouldn’t be a problem unless the battery heats up too much. Right?
You can Peak current is what that battery could deliver for short periods. 5 amp rated battery and a 6 amp driver is not the best combo. I personally like to use a battery that has twice the amps of what I’m powering. Not needed but gives a good cushion from driving it too hard.
