    It is possible. I don't have a wiring harness for it. If you are handy, the modules will fit, you would just need to custom wire a harness using your old one for the connector.

    Also an update, the batteries have finally cleared US Customs. Scheduled delivery date has been updated to Monday the 27th of November for all of you with pre-orders of this next batch.

    Any chance you'd ever be coming out with replacement modules (19.2v vs 14.4v) for HiHy's as well?

    I have two gen 1's and my batteries seem to be under control--a new pack in late '13 and my other gets Prolong treatment twice a year. I have mentioned your product on the Gen 1 sub forum as a great alternative to buying a new pack from Toyota. Can you tell me, off hand, what 19 of the modules would cost?

    This is interesting!

    Brian in Tucson,
    Not exactly your question, but just so you know, Gen 1 batteries at the dealer are about $150 less than Gen 2 batteries.

    I don't have or know of someone who has one first hand to test out everything.

    My next design will most likely be for the RX450h and then Prius C as I have those vehicles and it is personally beneficial. As with most of my projects, I do something the best possible for me. And then see if it is something the community would like or not.

    Basically rough calculations are $100/module.So for 5 more modules (19 vs 14), you're about $500 up. I also don't have a full wiring harness for a Gen1, so you'd have to cut/make your own.

    At that price, a brand new Toyota pack looks pretty good especially since Toyota actually discounts the Gen1 full batteries compared to the Gen2/Gen3.

    I would say for the Gen1, it makes sense to stick with OEM.

    It will be nice to have options many years down the road when our RX450H needs one(y).

    I can get a Gen1 battery pack at Camelback Toyota in Phoenix for less than $1900 and the will sell to the diy I believe. My interest in the modules in this thread is that they might be a good alternative to OEM. Alternatives are good!

    The RX450H uses the same 9.6v batteries as the HiHy so that would work great.

    <Yawn.>
    Just rolled 2,000 miles on the pack.
    Driving it like normal.
    Nothing else to report.

    As a reminder pack was installed 10/20/2017. So it's been just over a month.

    Also as a general update:

    The newest shipment of cells came in. They passed my tests and I packed them back up and shipped out to everyone who had ordered. This has wiped my stock almost completely out again. Every ordered pack from end of October through yesterday, was shipped out today. It made for one angry UPS man... Lots of 70lb boxes to pickup

    Yeah, my fedex and UPS guys give me crap about some of the batteries I ship via them, too.

    Just got the package today! Hopefully I'll get the old pack taken apart and new cells installed tonight.

    I also bought another Prius a 2007 that was wrecked in the front, has 77K miles on it :) I bought all the parts to fix it. I took the hybrid battery out of that Prius and swapped it in my current one. Unfortunately since it sat too long with a low hybrid battery voltage, cell block #5 is bad...but I will have plenty of good modules to swap to get that pack working again.

    Glad you got it so quickly!

    Just keep in mind the print instructions are not yet made. There is some good info here, and I have some additional pictures/images I can share if you need help.

    It is mostly self explanatory, but there isn't a booklet yet.

    It would be unlikely you could get them to fit back in the same space and get the plastic back ontop to make the compression work. And like you said, that's a lot of work. If you look at the teardown of some of the original cells, there aren't connector or anything like that, the cells are just connected together.
