Heres a question I have for people out there: Why the A123 Lithium Ion's so expensive???
I mean: I bought this pack consisting of 288 batteries, all soldered together to make a giant brick of 48v 20ah, with a charger, and a BMS for 450 + 150 Shipping. So essentially they are selling the battery for 450 dollars.
Then I look on Ebay and the A123's of which there are 288 in my pack, sold individually are 10 dollars each??? And the cheapest they get (lot of 100) is 300 dollars? Even in lots of 100, that makes the price $864, just in batteries, to soldier my own brick together - and then I have to buy the BMS + Charger after that.
So how are these battery brick making companies making a profit? There has to be a cheaper bulk source. There has to be some incentive to build a battery from scratch? If I repair my battery, replacing 4 cells, that means it costs me 200 dollars to get the amount of batteries I need. Seems like I could just tear my battery into individual batteries, sell those on ebay in lots of 50 and make the money to buy a new brick, and avoid the soldering work, and order a new 48v 20ah from Hong Kong.
This is ridiculous.
