Hi Patrick
We are very familar with the pecular charging requirement of the Nickel-Zinc cells , have been working with them for almost 10 years .
Assuming that the pack do what we can and upon the chart review , you decide to purchase them , how many would you need ?
Be glad to forward the charge and discharge curves of the battery pack , need a e-mail address .
Would like to mention that another firm in the West coast has expressed a interest and will be purchasing a large quantity , we would
like to make sure we are able to meet your requirement .
Regards
Michael
Hi:
I have a serious interest - we've got all the Leptons from the factory in PA. So it seems you've got the M40s from the new Chinese company that took over Evercell - interesting. We've got a lot of those, but they have aged several years, and it's not easy to bring them back to life. You might also note that they require a very unusual charge profile - the only company I know that will make a compatible charger (aside from the one in the Lepton) is Zivan, with a custom NG-1 and temperature compensation.
I'd like to see the discharge curves - could you send them?
Thanks,
Patrick
