Tiny LIPO based car engine starter - too good to be true?
BillTodd:
perfect reply Pete :)
there's an old saying:
experience replaces nothing , but nothing replaces experience.

I totally respect what Pete says. And have no disagreement with a Li-ion version costing nearly $225 U.S! I'd be happy to receive a $225 LI-Ion (or LiFe version) for Christmas.
As I said earlier, there is a big difference between Lipo and Li-Ion (and LiFe) in terms of safety (and price).The version I saw locally was I believe $75 and a Lipo, and I also stand by what I said about that. I wouldn't own one if it was free.
The plain fact of the matter is that 99% of consumers don't know the difference between various "Lithium" batteries, and could care less about what the abbreviations mean.
And if they can get one at a third the price, they will consider themselves lucky. Maybe unfortunately.

But Lithium Polymer cells (Lipos) are the ones with the really high output rates -- and the least tolerance for a lack of knowledge or improper conditions -- the ones I'm used to. And I'm guessing those are in the small booster packs. I f not, then I'd be more comfortable.

Here's a list of reported Lipo fires on a forum I participate in:

Just a few then :lol:

This thread is a very good example of trying to compare different technology's ,it this case lipo and l-ion the later as reviewed by Pete works and is a safer option but to compare it to lipo cell is a dangerouse oversight
One works and is safe but expensive the other may work and carries a danger and is cheap
As I posted caveat emptor
