Battery Reading Variance

I wish I knew the answers to your battery questions. sometimes it's best to trust the experts and just pay them to make it work. this for me this is one of those circumstances.

I got Duskie skateboards to hand make my board in Australia. he's a master of the craft. even did the depressions to make the truck plates sit flush. love the longer bouncy board with 97s. and even at 46 inch it turns so well. it flexes and makes the carve sharper.

Photojon. it certainly isn't as bad when it's all flat. surprisingly my cgt doesn't vary any where near add much as my bgt. so the battery % is way more reputable. it'll be interesting to see if my bigger battery that I am getting made ends up having less voltage variation.

 

The more sets in parallel you have the better as load is distributed (as far as I understand). Harder to sag.

 

So it's all about sets as you understand it? It doesn't mater is a set is comprised of 6, 10, or 12 cells? If that's not the case do you know how a 10 cell would compare to a 12 if all cells were 20a rated in both? Would it make a difference, in terms of Amp draw capability, if it was 3 groups versus 1? If so, what would that difference be and how is it calculated?

 

There is two things to take into consideration. Series and Parallel. The number of cells in series makes up the voltage and overall how much raw power sent to the motors. The Parallel makes for a higher capacity (longer lasting) battery. You will see people talking about batteries like 10s3p, 10s4p, 12s3p, etc... So for 10s3p there are 10 cells in series, and 3 sets of those in parallel. 30 cells.

 

I understand this already. My questions are not related to voltage or capacity alone. They are related to the performance of a pack in its ability to deliver amps. What I don't understand is how to calculate the amp draw capability of a pack made with 20a cells versus 30a. It seems that you may not either.

Obviously a pack built with higher amp draw capability cells should have higher capability. I wonder exactly how much given the same configuration?


Let's assume 20a capable cells:

20a x 10 in series x 3 of these in parallel, what's the amount of amps the that pack could provide?


Let's assume 30a capable cells:

30a x 10 in series x 3 of these in parallel, what's the amount of amps the that pack could provide?


Now, just for contrast and better understanding. Let's assume 20a capable cells:

20a x 12 in series x 3 of these in parallel, what's the amount of amps the that pack could provide?

Can you (or anyone here) answer these questions?

 

Amps has to do with just series as I understand it. Parallel helps with the voltage sag with large draws. That is how I understand it.

 

Me too. Bit that's about the extent of my understanding. So, can you answer my questions?

 

I can't specifically, but to just be clear, to correct your options, it needs to be 10 or 12 cells in series, 3 of them in parallel. You listed the other way around.

 

OK. Thanks.

 

Absolutely. It's working great. More distance increase than there should have been and solid in terms of sag. It's a beast.

 

I have one of the remotes before they introduced that ridiculous feature.
