hello everyone,
I have a some what simple question:
I've been driving my Bradley GTE for a little over 8
months now. during the first 6 or so months I seemed
to have about a 25-30 mile max range. making a 14 mile
round trip was no trouble. I commuted to work, 2 miles
one way. did not charge at work. sometimes I would
only have the car a half a day so that I could go home
and charge it, but many days I had to let it sit :(
lately the range seems to be decreasing. a couple
months ago, I moved and now my commute is 6 miles.
even so I've finally arranged to charge at work, the
batteries have degraded so much that I am just
creeping along towards the end of the journey! after
only 5 or 6 miles!!
also the rear 6 batts seem significantly warmer than
the front 4. I am drawing about [email protected] of the
way, more when going up hills and very little when
going down. my ave regen seems to be around 30-40A
(Zapi H2 [email protected] w/regen), but cant expect that to
add much of any range.
my questions are: have I destroyed my pack and will
need to buy new ones? how should I test?
was it the 2 mile drain w/o charging?
or was it the heat?
my batt configuration is a string of 10 12V Gel cells
94AH. either way I need to install some vents.

thanks for your input

Brian

That's some good information.....

But,

What are you using to charge? equipment/algorythm

What brand/model gel cells are these.

I hope your charger hasn't dried them out....

Hi Brian,

I have no experience with these batteries. Maybe
someone else will chime in. But, the spec sheet say
"for stand-by use". Nowhere does it say they are deep
cycle. Makes me think they are NOT deep cycle
batteries. Might be like using automotive cranking
batteries, maybe worse.

ok, I have my charger manual with me.
U1=140V, Im=11A
Um=156V, I1=9A
U2=128, I2=0,9A

C:70Ah

T1 max=9h
T2 max=3h
(T3+T2+T3)max=14h

is that the info you need?
I've noted that during U1 it is actually drawing 16A.
but I'm guess that is because of the power
conversion.... 120V*16A=1920W 140V*11A=1540, ya and
plus the losses....
