Hi,
"My motorcycle has 40AH GBS cells of which I use only 2 1/2 C and the cells are
still doing great 3 1/2 years later. "
To give us some terms of reference, what does your M/C pull in amps at a steady
50mph and 70mph (if you go that fast!) and on strong acceleration? And how
many miles do
I have 16 20Ah GBS cells and all of them off gas what smells like the
electrolyte solution. Put them in an enclosed box for a few days and
it is really obvious! I have not detected this with my TS or CALB
cells. I'm concerned that either the plastic, vent seals, and/or the
terminal seals are leakin

Correction; should be GBS-LFMP100AH cells.

Hi Lee,
Just wanted to check if it was 3rd-hand reports or not. If you say they
were bad cells, they were bad cells.
Are there any testing statistics on the more modern Chinese cells (Yellow
Thundersky, Blue CALB, etc)? Seems like people report a bad cell here or
there but not the categorical fa

Have you ever tested Enerdel batteries?

My earliest ones were from a group buy organized by Victor Tikhonov in 2003.
They were white prismatic Lithium-Cobalt cells, in both 90ah and 100ah

Lee,
Are those A123 still on the market? I haven't kept up on the
batteries/companies.
Are the test results available? Can you send me a CSV or similar?

As they say, caveat emptor.

Talk to Don Blazer (theoldc...@aol.com). He's been importing cells and
reselling them for a while. I bought my pack from him and was very happy
with the service.

I remember the Thundersky problem..
This is exactly why I am asking the EVDlist for "real life" experiences
bringing a small order (48 volt and 120 battery pack that came from China).
Sounds a bit scarey, has this happened to any of us?
Two outfits have said they will ship to my favourite
It's been a number of years, but I participated in a group buy from Thundersky.
Basically, they shipped us floor sweepings; rejects, old stock, and junk.
You need to understand that Chinese businesses are not bound by any of the
legal protections and ethics of US firms. Many of them take full ad
