mooch on you tube question

[susieqz]

mooch was just live on you tube.
he was taking questions.

i have a question for him i'd really
like to ask .
but, i couldn't figure out how to do that.
is there someplace i need to go ?

can anyone tell me how to post a question, please?

You have to be signed into youtube to go into live chat and post a question. Why don't you just ask him here? He's active in the batteries and Chargers section, or you could ask him by PM.

 

[susieqz]

thank you.
i don't wanna pm him because that would feel like an imposition,
i don't know if i'm signed into you tube, but i'll go look.

What is your question?




@Mooch

 

[susieqz]

well, i vape a 2 battery mod around 30 watts.
i ran the equasions n they tell me that a 10 amp battery would be fine.
but, everyone tells me to stay with 15 watt batteries,
i wanna know why n if they are wrong.

 

[smacuser]

What's your mod?

Sounds about right. You might consider 20 amp batts.

 

[susieqz]

sigelei sobra, but why 20 watts?

 

[G and C]

sigelei sobra, but why 20 watts?

Watts and amps are very different things.

 

[susieqz]

oh, i meant amps.
i ran the equations for amps.

 

[vaper1960]

You should be fine only running 30 watts... BUT have you checked to see if your batteries are actually 10 amp constant? Mine say 30 amp on them but Mooch says they are actually only 20 amp (still work fine for my needs)
Didn't know about Mooch on YT... cool!

She has 30Qs

 

[susieqz]

nah. i'm trying to find out why i shouldn't use 10 amp batteries,
people said i shouldn't.

It's always a good idea to overshoot your amperage by a bit. Running at or close to a battery's cdr all the time lessons their lifespan. Or can. I would take Mooch's word over anybody else's though.

 

[vaper1960]

Watching Mooch"s first live Q & A video right now (from 2 years ago) Good stuff.

That statement is kind of a safety based blanket statement for a lot of newer vapers that use higher power mods, which demand more power than what a 10A battery can supply. If you don't plan to go any higher than 30w, two 10A batteries should fit your needs fine. You would be using about half of your total CDR.

Your math is not correct. 30 watts with a 2 battery device equates to roughly 5 amps per battery (that’s a rounded number)

30 watts/ 2 batteries/ 3.2 volt cuttoff/ 90% efficiency = 5.2 amps per battery

Our goal is to not exceed the battery rating. Matching the rating is not necessary. By using a battery that is rated higher than your output, you being less stressful on the battery.

There is more to batteries than just their CDR and mAh rating. As mAh increases, CDR must decrease. However, internal resistance also increases. Higher internal resistance = higher voltage drop which equals hitting that 3.2 volt cut off sooner.

According to Mooch’s tests. The 3400 mAh, 10 amp CDR LG MJ1 drops to 3.2 volts with a 5 amp draw faster than the 30Q does with a 10 amp draw. So if the 30Q was operating with a 5 amp draw, it would vastly outperform the LG MJ1

The 30Q is an excellent all round battery. For your purposes it is pretty much the perfect choice. Choosing a lower CDR battery will most likely lead to poorer performance.

 

[susieqz]

thanks, punk.
i needed that explanation.
i looked but couldn't find that test.

There is no direct comparison tests. You have to look at each individual battery and analyze/compare their tests with another.

Yep.
