Question Demand for Blacktip/Cuda X 15ah batteries?

[BigGixx]

You’re not wrong but whitzrac was talking about a turnkey service. What’s your time worth? Did you have to buy or build any tooling? I don’t know about you but I don’t work for free unless it’s a buddy and even then I demand pizza and beer.

@Whitrzac , what cell is DEWALT using? Are they really only 80% of the better cells? You’ve piqued my interest.

I was saying to take the gamble, this isn't rocket science...or is it? Some math, some arrangement and tooling and your almost home. However, I do agree, if this is something you are doing for yourself than good, if for someone else, YES, they need to pay for your time!

Still only 540wh.
Also wouldnt fit in the piranah without a custom PTB. The piranha uses the old 18650 based dewalts.

My math tells me that 2 15ah batteries in series at approximately 20v each is over 540 wh , without tearing into the pack to upgrade the cells.

the pic below is the beginnings of a PTB housing for my piranha, they fit just fine

Dewalt PTBs SAY 20V, but they are really 18V.

18V * 15Ah * 2 = 540.

I presume they are 5S packs and that dewalt would rate them generously.

I don’t know enough about li ion voltage variance as they are discharged to know what voltage should be used to calculate watt hours. 3.7 x 5 gives us 18.5V , apparently mine are mostly charged :

 

[Whitrzac]

WH is measured at nominal voltage, not peak.
3.6v/cell is nominal for LiIon batteries.


Anyone saying/advertising different is trying to mislead you
