Hi, I found a blog that describes what I meant...800 cycles. Inside the quotes are the borrowed thoughts: "
Plug-In Supply, Inc has just unveiled the “PbA10″ Conversion System last week at the Plug-in 2008 conference in San Jose. Their system is based on the CalCars’ Open Source design, and it turns a standard 2004-2008 Toyota Prius into a Plug-in Hybrid Electric Vehicle (PHEV) with an all-electric range of 10-15 miles and improved average mileage of up to 100 miles per gallon (plus 1 cent/mile of electricity).
The conversion system uses a 5 kWh lead acid battery pack. The lead acid batteries are not old-fashioned, as you may think: they have a new extended lifespan of more than 800 cycles. The system is also very flexible, because it allows the user to upgrade to lithium-ion phosphate batteries which give your electric vehicle a range of 15-20 miles and a maximum speed in all-electric mode of 52 mph. The costs for these longer range Li-Ion batteries get lower every month.
The Pba PHEV battery pack is ready for commercialization. It contains 20 PbA20-12 lead acid batteries. It also contains the high voltage control systems closed in a steel box. They are built to last about 2 years, which is kinda short for a system that costs about $5000. The weight of the PbA system is 360 lb (163 kg), compared to 150 lb (68 kg) for the lithium-ion system."


This is my understanding. I don't mind the stealth button being high. I can reach it but I don't think my wife can.

Yeah, the installers wanted to put the button up way up on my dash. I requested for it to be installed onto the blank button console panel.

Good queston. I don't have an answer yet. I'll have to check with my installer. My info was that Plug in Supply was using a better Lead Acid that was going to get more charges, about 800? That's what I mean by more range, I should have said more cycles. I'll try to follow up. From what I can tell your conversion is identical to mine except your stealth button is on the dash and mine is up high on the dash by the window.

Extended range batts?? Are they the BB Battery EB20-12?

I haven't got a LiFePo Pack yet. I have the extended range Lead Acid batteries and should be able to upgrade to LiFePo when these lose their charge. Plug in Supply made this kit upgradeable with the lithium batteries in the future.

Where did you get your LiFePo pack from? How much did it cost? What's the range?

Thanks for sharing your conversion. I too had a plug in supply PHEV built from a 2007 salvage package 9. You might enjoy checking out my photo album. I have a blog about the car on Our New PHEV Prius!
