Looks interesting, I've been waiting for Li+ to start making sense on
larger scales.
The cycle life does not appear to be better than a HUP lead acid
battery, despite the claims of "10 times the cycle life of an AGM
battery" I'm confused because in their white paper they also claim: 200
cycles at 100% DOD < 2000 cycles at 80% DOD > 3000 cycles at 80% DOD.
What does that mean?
Also the warranty has 3 yr free replacement, 10 yr prorated, but doesn't
cover shipping or installation, and also demands an engineering
evaluation of the installation to allow the warranty. Despite their
claims of being the most comprehensive warranty in the business; it is not.
My entire power tool collection as well as my computer and phone run on
Li+, so I'm a believer, but I've also been vetting BS claims in our
industry for over 2 decades. Corvus needs to put more time into some
BCI cycle life charts, and provide a warranty that covers shipping and
installation time like others. Some case studies, and independent
testing would help as well.
Anybody have any ball park pricing on this?

Wrenches,
In order to provide accurate information about lithium-ion
batteries, I'm looking for referrals to current suppliers with
available product, with specifications and retail pricing
available. Having read Randy Richmond's article on Li-I in HP153
earlier this year and Dan Fink's posts here, I understand the
advantages and limitations. I am just looking for actual supplier
websites and contacts, please.
Thank you,
Allan
