Meh High amp chargers lower the amount of cycles you can get out of a battery, I stick around 1a.
Hi
I don't think you are right, because if the battery is good quality and internal resistance is low (this is good quality) - so even in datasheets it is written that you can charge at 1C (which means 1x capacity of battery) - and this is exactly 3A in case of 3000mAH batteries (like LG or Sony or Samsung - from the highest quality)

And BTW in this charger you can limit the charging current down to 0.5A

I trust Mooch's opinion (see link above). He's the expert as far as I'm concerned.

To minimize any impact charging has on the life of your battery, charge at...
26650 and 18650 = 0.5A
Smaller than 18650 = 0.25A

For a good compromise between battery life and charging speed...
26650 and 18650 = 1A
Smaller than 18650 = 0.5A

For the fastest charging without severely affecting battery life...
26650 and 18650 = 2A
Smaller than 18650 = 0.75A

If you really just don't care about battery life...
26650 and 18650 = 4A
Smaller than 18650 = 1A​

Hi Guys,
Again:
What I know is that the DISCHARGE rate is what affect battery life, and NOT the charging current, as long as you are in datasheet specification.
You will also NOT find comparasion of Charging current and battery life, but you will find curves and graphs about battery life and DISCHARGE currents.
For example look here:

This is the LG HG2

And the morale of the story is this, if you can't get by with charging batteries at trickle charge speed, ie by the time you have discharged a second battery yet the battery in the charger is only 50% charged still and this leaves you no batteries to vape with, "You need more batteries". Working in a vapor shop I see this all the time, especially with mech sub-ohm vapers, to cheap to buy enough batteries to last them an outing or day yet have plenty to spend on 6 bottles of juice, and complaining they always need to wait for their batteries to charge to vape. I have various batteries for my various devices, 18490/18500s for my Provari Minis, to 2 Panasonic NCR18650B's for my SVD's and Provari P3, to 8 HB4 and HB6s for my mechs, 3pairs of VTC4s for my IPV3, Sig150, and Kbox200, 6 25R rev5's for when needing a little oomph in my single battery mods, 4 button top 25R rev3's for my Reo Grand, and about a dozen HG2's (half charged and in use, half still new in their boxes). Not only do I rotate through devices throughout the day, I rotate batteries to be used through out the day, comes out the mod gets set aside at least an hour, put on charger, once charged gets set aside to rest then put in the back of the line of batteries for use later, could be 3 days to a week before they get use. Single battery regulated you need 2 batteries for proper rotation, single battery mech you need 4 to 6 batteries for proper rotation, double battery regulated you need 4 batteries, dual battery mech you need at least 8, triple battery regulated you need 6 batteries, that is about bare minimum numbers you need to prevent over wear an tear as well as not having to rapid charge batteries all the time, customers call BS on me at first but later wisen up once they get experience later down the road.

In part, the biggest killer of a battery is heat. High current discharging causes heat inside, the reverse plays effect as well while charging, batteries are notoriously grumpy when charging, analogy you are pressurizing a can through a pin hole, this natural resistance of being charged by a battery causes heat as well, more current pushed in the hotter their temper gets at being pestered so. So high current rapid charge and high current discharge both are slicing the battery's wrists ever so slightly every time you ask them to do so. Rapid charging is good in an emergency, but doing so all the time is just being careless, one day a battery will go boom being abused this way while charging.

How I like to roll as well. ~20 single 18650s for single batt devices & mechs, ~10 married pairs of 18650s, 8 single 26650s (no dualie 26650 devices just yet), 2 married pairs of 16340s for the Billet Box and a handful of 18350s for the zmax mini. I knew I had to stock up on batts. Should be common sense with working with multiple devices that rely on battery power. Once you have all of those batteries, it is a wise decision to invest in a 4-6 port charger. I love my 2 bay nightcore digicharger, but found a good deal on the Efest Luc6. It works well and has a charging rate something like .64A (I can tell the difference between charge times of the NC and the Efest. Only gripe with the efest is that the two inner most bays give funky remaining voltage readings sometimes. It will initially show .2 volts greater sometimes. I'll remove and reinstall the batt and the reading corrects. Doesn't do this in the other ports.
