Matching batteries question

[Vulupshatusk]

I used some new 18650s in a single battery mech mod. Im just going to get a new regulated box mod that going to use dual batteries. I only used these batteries one at a time for a week or two would it be safe to use these as a pair now since I used them separately for a short time.

If your batteries have a 20amp continuous rating and your regulated mods batteries are in series do you still need to keep your amperage 20amps and under? I ask because somebody said in another post that they would split the total wattage but in series wouldn't the total amperage go through both batteries?

I made the mistake of taking a vape shops advise on what brand of batteries to buy and he told me he used mxjo and I just assumed the 35amp was the continuous rating but I know better now.

Yes, you can still marry them because two weeks is not really that long.

On a regulated mod, series or parallel or paraseries just doesn't matter in terms of how many amps the continuous discharge rating (CDR) of your choice of battery should be for safety.

Check out Mooch's list of recommended batteries, and, because he's narrowed it down to only a handful of choices, also be sure to keep up with all his battery tests. A quick easy overview of these tests can be found here: http://www.tasteyourjuice.com/wordpress/the-battery-mooch
Sure, that list of tests has gotten quite long, but I've been digging through it a lot so if you'd like I can help you navigate to the ones that are worth checking out also (i.e. in addition to the ones that he's still kept on his list of recommended ones).

Thanks for the reply! Since the reg mod bats are in series I can't go above a single batteries discharge rate right. I have to use what batteries I have for now. I have some older Lg but they are 20amp as well.

With a regulated mod, you can totally ignore it. The mod limits your amps and voltage according to a formula based on the wattage you set it at. That is the simple explanation without going into the various formulas and controller function. All you need to know is they work. Just make sure your battery wraps are always in good shape with no nics or tears. That will be your main safety concern.

As for using your existing batteries.. if you didn't stress them, and recharged them at about the same level, you would likely be ok to use them. To be honest.. i would just scrap them and buy samsung, sony or lg and you KNOW what you are getting. MJXO is the worst group of liars. Those 35A batteries are more likely 20A rewraps of a factory 2nd, LGHG2 if you are lucky.

Also post the name and location of that vape shop here. There are a LOT of people that just don't know so a warning might save someones face. Also, see if they have a facebook page and post there... they have no business being in business.

No, like I already told you, on a regulated mod it doesn't matter that the batteries are in series when it comes to battery safety. Ignore comments from @gbalkam because he has absolutely no clue whatsoever... his so-called "advice" is flat out dangerous, and, for a reliable explanation of how to determine what batteries you should be using, just watch this video instead:

Oh sorry I just assumed the video was listing batteries, but WOW is it informative. Thanks! The only thing that seems kind of foreign to me was the efficiencies part of the equation.

The DC - DC converters on the various regulator boards operate a differing efficiencies. And the efficiency may vary quite a bit from low wattage output to high wattage output for any given board.

There is loss involved in the DC - DC conversion process.

So on the same board the efficiency varies from low to high wattage. Is the only way to know the efficiency to look up information about your board?

Yep if you can find the information. And how accurate will it be?

Be sure to check out his other videos too. There really is a wealth of dependable information and advice there, with huge emphasis on dependable... the absolute last thing we need is some nitwit's ill concoction of the mind about lithium ion rechargeable batteries we use for vaping.

I definitely will!! Not only do I need the information, I love learning about electricity.
