What's the total voltage/amperage?

Imagine every gas station converting, a few banks at a time, to electric quick-charging stations. The network of stores is already in place, and then those socially conscious oil execs could get their nice big slice of controlling the EV market as it develop. And as a bonus, eventually we could all anticipate seasonal mark-ups on electricity at the battery-pump. Coming someday to a station near you!

Each "battery" is 45 AH @ 24 Volts.
Wired in parrallel I had 4kwh of storage, now I have 6.
I had 8 x 6 volt 330 AH lead acid batteries wired in series for 15.3 kwh @ 24 volts.
The beauty of Lithium is you can draw down to 20% of the tank vs. a regular battery which you'd kill rather quickly if you go below 80%. So with the initial 8 batteries (that I could only draw down by 20%), I had 3.6 kwh to utilize. BUT......you really don't want to play down there too often. With the Lithium batteries with 4kwh I can draw down 80% of the capacity...thus 3.2 usable khw.
These are Gen1 batteries, already 2 gens old. These are technically as advanced as an 11 year old laptop. These should last me another 8 years but I'm waiting for LiFePo to come down, (it already has by 50% in recent years), or the "next big thing".
But while technically and physically "old" (2013), the demand on these batteries is minor compared to what they had to do in a car. Fans, defrosters and passenger cabin heat all came from the batteries...all power killers as there is no hot radiator fluid to draw the heat from....it's like a toaster, blow dryer or electric space heater.
That is why they have this big of a pack.
My next upgrade this spring is a better BMS to keep the cells balanced.
This is one of the better ones out there.
