Re: Cost to replace an i-miev battery?

Yes. I have a KWeld unit. Made in Germany and works really well. I bought it to build an eBike battery. Two pieces of advice: make sure the charge/discharge rates on the cells are compatible with the car (125 amps on quick charge, up to 150 amps discharge), and make sure whatever you use to build t...

Re: Cost to replace an i-miev battery?

Anyone got first hand experience of a decent spot welder to put batteries together with?

Looking at this at the moment...

Re: Cost to replace an i-miev battery?

20 x 21700 LG M-50 cells ordered and on their way for initial testing. This is enough for a 100 Ah cell, double the capacity of the LEV-50 used in the car currently, lighter and in the same form factor. If I can get it to work, a full pack (at the price I paid for 20) would cost £5200 just in cells!...

Posting this thread here as we're likely going over a lot of old ground already covered otherwise.

What we're really waiting for in 2020 is this fated reduction in battery cost to filter down to us lowly home gamers.

Re: Cost to replace an i-miev battery?

So I'm looking at 18650 3.7v 5000mAh Li-ion cells. Using these would of course mean assembling my own battery packs from scratch BUT... To purchase just over the required replacement capacity for the standard I-miev, the batteries I have found so far would only cost £660 in this format. That sounds ...

Re: Cost to replace an i-miev battery?

Well... Here we are in 2020 And here I am with a 2010 I-Miev, with only 27000 miles on it, that can only just cover 25 miles on a full charge! So this thread is more relevant now that it was when it was first posted but there is still no good news regarding official replacement costs I see. I have a...
