Comments about your Lithium Battery

[DaveTM]

I've had to look up the chemistry of the Leaf battery a hundred times or more. I think it's (LiMn2O4 with LiNiO2).

For whatever that's worth!!

I think that's right but I would have to dig out my specs that I got when I built my Leaf pack 6 years ago.

Had to do the "push of shame" home.
All I would like is to know where I'm at range wise when I'm getting near that envelope.
In my community, you can do 40mile excursions anytime.

Okay, and this is MAYBE might could be semi-accurate...or not!

Take a ride while measuring the miles on your phone or other device. Watch the percentage gauge and when it hits 80%SOC, see how many miles you have gone to the second decimal.

Since you have USED 20%, divide the miles by 20 and you will have a number of miles per 1%. Lets say you ride 8 miles when it hits 20%SOC.
8/20=0.4. Then 0.4 times 80 usable SOC equals 32 mile range.

(Note) I was wrong on BGW a couple of times this week already, so feel free let me know if I am doing it again.

As others said, this is only good on LFP and maybe NMC battery packs. This is due to the very flat voltage line on these. Voltage cannot be used on these packs accurately. I don't even read my voltage.

Thanks for your response, biterope! This is the second Husky reviewed here.

Just fyi and a bit of friendly advice from personal experience, my cart did about the same with my bandit motor. I would recommend to keep it under ~25mph. My bandit blew up on flat ground at 28mph on the same diameter tires (205/50-10 also 18.5”). Robby said it was not rebuildable so I scrapped it.

11) Average and Top speeds - Average is about 20, Top Speed so far was 30
12) Likes or dislikes - Like
13) Additional comments - Super happy I did it and I earned a lot. Did this before real drop in options were available and while I would do it again, I would strongly look at the drop in options if I did this again (my choice would be the Eco Battery). Would like to do one more cart for around the property (would be a CarryAll) and will definitely go Lithium if I find one

Thank you for your response, Bruce. I know you are happy with your setup. It is performing well for you. Eco Battery is going to have to wait...unless they want to use your cart as a test vehicle!

Ok....I'm an old guy getting lost in reading the post.....why is the Eco Battery going to have to wait? Issues with those installed now and awaiting new "fixed" ones?

This is referring to an ongoing satirical discussion with simicrintz. He "lives" at Eco Battery headquarters in Hurricane, UT. Free lunch, you know.

Anyway, they are working with him on his cart and future plans may include hot-rodding it with an E.B.
