Re: (ET) ET) Wanted, information on installing Lithium cells in my EGT 200

As someone who went to NiCD years ago (and will never go back :-) I can say that the reduction in weight is something of a problem. Especially in the front; when I till I need a weight box in the front of the tractor to keep the front wheels down properly. 30 BB600's don't quite cut it.
Each BB600 cell weighs 3.7 pounds I think, so 30 of them weigh about 100 pounds for 30ah. CALB cells in the 100ah category will be of similar weight.
One thing you could do is fit Lithiums in the back, and just leave some lead in the front.

Hello Barry
The CALB LiFePo4 cells will far out perform lead. Also the new CA series
from CALB will give you 15% more capacity in cold weather use. The only
thing I can think of that would be bad for a tractor is your going to
lose a lot of weight. This is great in an EV but not so much in a
tractor. The extra weight in a tractor is a useful advantage but the
lead acid chemistry is a loser in every other category.
Your Ranger friend might have bought the CALB cells from me. I have
supplied in the last year cells to several different Ranger drivers.
If not he most likely paid a lot more
I can provide any size cell contact me off list on pricing as I am not
allowed to give this information out to the general public.
When you want to grade or scoop that is something to consider. If you
remove that much weight I would think there are times you might have to
replace it.

    The 7 year old lead acid batteries in my EGT 200 appear to be dying.
    I would
    like to know if anyone has personal experence using lithium
    batteries in a
    similar tractor. I need for the lithium cells to perform as well as
    the lead
    acid.

    I mow about 1 acre and use the tractor for many other assorted jobs: A
    little tilling, grading, moving stuff with fromt scoop, grading with
    the box
    blade, towing small trailer, using the electric winch on the rear.

    I know I will have to add weight to the tractor.


    I am familiar with the CALB batteries. I just helped a neighbor
    install 104,
    100Ah cells in his 1999 Ford Ranger EV.


    I have created a website for his Ranger.
