questions about battery charge mismatching

[icicle777]

hi, any help would be really appreciated. a bit of background info:

i'm usually a 3.7v mod user, but i'm looking to "up the ante" if you will. my friend uses a 6v device, but i find it a little too strong for my throat. once he's been using it for awhile though and the batteries have been sucked down a bit, the strength and vapor production/flavor is really great. i'm assuming it's around the sweet 5v spot lots of people talk about, or maybe even somewhere in the mid/high 4v range.

here's my question:
would it be crazy (from a purely technical stand point) to hypothetically use 2 rcr 123a batteries, one battery being completely fresh off of a charger and one battery just kinda charged but not all the way? would it damage the batteries really quickly and if i try this with unprotected batteries will they pop on me?

i'm trying to figure out a way to use a 6v device with a relatively accurate sub-6v output without fulling charging 2 batteries and then running them off to some vague point.

low resistance attys are great, but with the super short life span i'd drive myself nuts having to restock every few weeks.

thanks in advance for any help anyone can give me.

icicle,

When you place a fully charged batt in a circuit with a sub charged batt, the sub will pull down the voltage of the full one and they will equalize to the lower voltage, not average out unfortunately.

So technically speaking yes it would work, but...
As your starting voltage would always be different, you would never have reliable repeatablity both in attomized volume and quality, and in battery up time before a recharge is needed. If the "sweet spot" is found on the low end of a batt discharge cycle, then it won't likely last that long.

Then you have the hassle of finding or making a partially charged batt (how much is too much/too little?) bringing me to my other main concern, i'm not familiar enough with lion batts to know if this type of short cycling will kill the life of you batt due to memory issues.

If you want reliable repeatablity in a higher voltage than 3.7v (and know that 6v is too much), I would suggest a battery mod delivering 5v from a fully charged unit.

You can mod the unit by placing a load resistor between the batt and the atty to purposely drop the voltage to a calculated 5vdc.

Better yet, a variable resistor and then you can dial it down to exactly what you like when your batts are fresh and back it off as you want as you go through your vape session and voltage drops off.



Just my 2¢

thanks for the advice, i'm going to hassle my electronically inclined friend into helping me figure out possibilities of adding a load resistor to my mod. he thinks he might be able to modify a shelled out atty which would be kind of amazing.

in the meanwhile, i'll start looking deeper into hopefully finding a dedicated 5v mod. so far my options seem really limited though.

thanks again!

The quicker but more expensive sloution would be to find a 5v battery mod option for your model and be done with it. But it only really costs you time to try and make your 6v configuration burn at 5v
