[RE-wrenches] LiFePO4; WAS Availability of Powerwall Batteries

[August Goers]

Larry,



To get back to your previous response to me – I’m fully onboard with the
benefits of lithium batteries. For now, they seem like the clear successor
to lead acid technology. However, I’m still concerned about the ability of
these smaller “integrators” to assemble cells and electronics together and
make a robust package. There may very well be good ones out there, I just
don’t know. Tesla’s product is still brand new and who knows how that is
going to go.



Best,



August

Hi Allan,



I would like to challenge the use of the term "locally manufactured".
Mccune Solar Works does not manufacture lithium batteries. They purchase
battery cells from China and package other third party components like EMS
and relays to make a lithium battery  system. Very similar to what we do
except our LFMP battery package EMS and CPU is designed by the manufacturer
exclusively for GBS batteries. Perhaps a better term would be LFP battery
dealer or integrator.

Wrenches,
A longtime off grid friend of mine, with whom both I and Positive Energy
have collaborated on difficult installations over the years, just purchased
a 24V 230AH, 120 lb. LiFePO4 (Lithium Iron Phosphate) battery bank that is
locally manufactured in Albuquerque. It's still too small and too expensive
to run his entire home, so he has devised a battery switching system and is
keeping his older FLAs in operation while he tests these and affords more
strings. So far he's quite pleased with the performance, but there's not
yet a track record for his set.

So I want to pass on this low-key manufacturer: Chuck McCune, McCune
Industries, http://www.mccunesolarworks.com, (866) 622-8630. I believe that
a legal Non-Disclosure Agreement is necessary to get the real info.

Contact me off list if you'd like to speak with my friend with the new set.
I believe that he has set up as a regional dealer.
Allan
