@Ravi,
Great thread and good questions !
The cost should be , and many will be
, but that's where we have to arrive, at the cost of 325-375$ max. for that battery (48/14amps, smart BMS) .
5 year warranty - an additional 125$ =500$ MAX, preferably 400$ max.
Do you guys know that we are talking about 46-50cells ? How many cells it depends on the type of cell... For Liquid cooling add 100$, actually not sure about this one, cheap vs expensive cooling prices ?
If a pack has a ridiculously high price of 600$ or insanity high of 1200$ it only speaks of about the lack of education on behalf of the customer.
Why do i make that statement ? A typical electric car (ex. TeslA 3) has
4416 of those cells . Imagine if it were like this: 46cells at a cost of 600$ X 96 (4416:46=96) =57,600$ just for the battery pack !! But no, that pack is about 10.000$ maybe 9k now ? , that's roughly about 125$ for the 48/14ah pack of cells ONLY.
In our case we need a case and Bms for each pack..add 17-19$ for those:
the PVC case, 0.001$ worth of wires ,
the tiny silicon wafer with the simplistic chip aKa BMS , and another 125$-unlimited* for labour/profit
.Allthough profit is not really needed in tne first few years as long as there are many sales.
Right now we are all (except DIY folks
) getting fleeced having to pay ridiculous prices of 500$-1200$ for about 46-50batteries enclosed in that PVC case with the BMS.
Congratulations BOSCH for selling 125$ worth of lithium + the few $ for the remaining parts for 1000$
. NO WONDER you made your own Laws via lobby(People for bikes) aka Class 3 law in US , in EU and elsewere...and most ebikes run on Bosch motors...hmm maybe we
should call our state AG's
? We just had the very recent Google:

Companies nowadays they recycle the batteries , also our used batteries should be bought back(if one pays 600$ and after 3/4years it has 80% SOC, that battery should be bought back for at least 25% off the orig. price (the lithium/nickel/cobalt/graphite are only going UP in prices) and bY UP meaning 100-300% higher if i look at the recent history.
The problem is where will the cells be made ? That can bring the cost down or Up. A Tesla module of 95% or even 100% SOC 21700 cells has a very reasonable price( not many avlb. online 4sale...) i'm sure one could build a 48/14-ah pack , resell it for 375$ and still make a BIG profit. That's almost 90-100packs
from a lightly or unused module(not a lot of them for sale on the online market though !)
Only A big company could bring those prices to that level.
Lower battery price > ebikes being sold !
Lots of i
ideas here , prob. a few minor mistakes, looking foward for some realistic opinions.
*= up to and not any higher then 300$ ! If high inflation we may need a price adjustment .
- the pics of Tesla pack are a little old , maybe some other "fanboys" /
"fangirls" /non-binary fans have recent info ?
