Truthfully, This is my third EV. The other two were FLA battery powered.
I am VERY experienced in their installation, maintenance and upkeep as well as their little quirks-strengths and weaknesses.
If you really looked closely, my car was set up for 20-6VDC GC sized batteries.
It would have been OK with them. I would have been OK with them.
As with so much on the internet, I read and re-read so much about lithium batteries that it made my head spin. So much contradictory information. Lots of it was by persons never having owned any....Just what they read on the internet...
I started watching and listening to people who Actually own Lithium batteries. Their good and bad stories , Ignored everyone else and formed my own opinion.
As stated, I was suddenly able to afford a medium sized pack. Even then, it took a lot of soul searching to make the switch.
I decided several things:
I decided to NOT use a BMS. (Many BMS failures, many people hawking their systems and stretching the facts, and no system did the things I considered important.-No I will not explain any of these-They are my opinions.)
I decided that maintenance was still maintenance. I just had to do it differently when switching from lead to lithium.
I found it hard to ignore the tremendous weight savings.
I considered the performance/capacity/C rate improvement a plus also.
Just the short time I have been actually driving the car, I really like the "normal" light/nimble feel to it due to the lack of 1,800# of batteries.
No opinion of the range improvement, too soon.
No opinion of the possible performance increase due to the switch from DC to AC system kinda screws a seat-of-the-pants Battery Comparison
So far, I have found that some of things expounded in the forums about lithium is at best inaccurate. (More on that at a later date.)
I still believe that a Lead car is a good first "learner" car. OR a good vehicle for those with no other choice. (Lead or none, choose lead.)
In closing, a last question: My pack stops charging at 3.345 average/cell.
I have 1 that is 3.91/cell. I am going to pull that one down to the 3.345 area to match the others. Is 3.345/cell decent for a non-BMS pack, I think so.
