Parallel batteries?

So are parallel batteries as dangerous as stacked batteries?

The trouble with parallel batteries is when sooner or later you're putting in your two flattop batteries and mistakenly put one in the wrong way.



Coincidentally I happened to have fried my dual bay charger last night by doing that.



With a stacked battery mod, if you put the batteries the wrong way, it just won't work

Simple answer, No. Parallel batteries share the load so if you're running a 20A RDA setup each battery will only be required to output 10A. Stacked batteries do not split the load, stacking batteries causes more strain on each battery.

Barring any sort of user error, Parallel battery mods can be pretty foolproof.

Wow edyle, that's too bad. Any other reasons why parallel batts can be as dangerous as stacked?

Thanks! That's the kind of thing I need to know.

No, not that I know of;

It used to puzzle me why the manufacturers seemed to be using series batteries instead of parallel, and I suspect on balance it is because of this safety issue where a user can accidentally put in the batteries the wrong way sooner or later, and when that happens bad things happen INSTANTLY.


With series batteries I *believe* the more significant concern is not so much safety but battery life if one battery gets too far out of sync with the other

Wow...

Try this...

Way more than I need or want to know. I won't be using either anyway but wanted to know in general if batteries running in parallel are as dangerous as stacked. Thanks for the link anyway.

Parallel shares the workload resulting in less stress on batteries and longer battery life, but does not increase power. Stacked is the opposite.

Parallel for teh win in safety and practicality.

Both are equally dangerous in the wrong hands.

I found the answer

Good! That will help the topic starter.
Oh wait, you didn't share your findings...

Parallel: 4.2v @ 20a = 84 watts (10 amps per battery)
Series: 8.4v @ 10a = 84 watts (10 amps per battery)

Right on Spirometry
