Review UPDATE Hymotion plug-in battery after 100,000 miles, 14 years, and 4000+ cycles

thanks for the update, congrats on a great run! miss you man

 

Interesting, and serendipitous. I have a 2005 that's something of an odd duck. Buddy who sold it to me bought it from the original owner w/ dual NiMh battery set up and a side port for some sort of external charging. He removed that gear & converted to a single battery set up that's still getting 48.4 at 136k miles, but both original batteries were traded in for the single rebuilt one.

Have another '05 that I'm putting on the road for a family member, and was interested in purchasing a new module set from Dr. Prius/Project lithium team, but I can't find any contact number to call, and they've been completely awol in replying to emails to their sales info address. Couldn't get their store front to give me a correct shipping cost (it kept adding more and more freight charges that didn't make any sense) but since I can't get anyone there to respond through their proffered email system, and there's no number to call, I'm stuck. Glad to hear you've had a good experience w/ them, as I now have two more that I'd like to convert, but I'm not feelin' much love thus far. Any tips would be appreciated.

 

One of the testers @PriusCamper can connect with you, he can deal with the manager directly.

Thanks @alftoy for the heads up... I'm in touch with them at least once a week but usually more often and can do all I can to help get you hooked up. There's very few packs remaining so it's urgent you get back online and get your order in. Shipping a ~40 pound box of lithium batteries is not cheap and costs a bit over $100.

Sounds like your problem is you have erroneous charges in your shopping cart?

Here's a few things to try one or all of:

1) empty out shopping cart and start over
2) clear your browser history
3) go into incognito mode and enter your info with a different email address

And as always, if you use my affiliate link that's in my signature to order I'll put as much time as you need into this to get your issues resolved.

 

Did and done, thanks, but still not loving the complete lack of response and total lack of contact means. Glad you're in touch with them weekly. I would have appreciated speaking to someone at least once, especially since my partner and I were seriously considering adding their batteries to our shop & mobile services. Still interested, we're just a little more old school and actually use our phones as phones too.

 

And the functional problem that I was having w/ their site was that it added an extra shipping charge. I full well realize that 40 lb. boxes of placarded batteries don't ship for free, it's just kinda silly that I need go through Priuschat to get squared away, but thanks. Seems we're now on track.

 

Good to hear! I'll personally communicate with him for you if anything comes up... He always replies to me the same day I message him. I'll also let him know you're a shop that's interested in long term business. He's been very generous to me and certain he'll be that way with you too.

I think in your case that situation was that you hadn't made the purchase yet so your were a prospective customer rather than an existing customer and he gets lots of people who never buy who ask him lots of questions and he has a limited number of experienced employees.

I remember one dude a couple months back. We both had several long emails with him regarding super cold weather performance and not only did he not purchase but he got into a Facebook Prius group and said all kinds of dishonest negative stuff and claimed we didn't help him out and I'm like, "I spent more than an hour replying in detailed emails with solid references." But it was the usual social media troll that asks you to back up your claims with references and then you do and they discount them as invalid faster than the amount of time it takes to skim through them. Those kinds of people aren't worth the time you put into it.

 

I have a 2006 Prius with the Enginir kit, a 74 cell 40ah battery so nom. 240vdc. The range on ICE Kill EV only mode was roughly 80km at 80km/h max speed, fine around town but useless on the highway. If I kept the travel distance to less than the extended range pack capacity, 1 averaged around 2.5ltrs per 100km , a Google calculator says that is 94 US MPG. Not quite are good as your 100 MPG, but not bad.
I'm in the process of fitting 84 x 55Ah LTO cells into Prius. Rather than loosing the boot under floor area where the spare wheel and jack could go and wasting the spare wheel well, I looked at mounting the cells with 12 in the wheel well, a layer across the rear floor and the rest built 3 layers deep to match the shape of the original NiMh battery.
It would have fitted nicely but I had another think about it changed to 48 cells where the original NiMh battery was and the remaining 36 cells in where the spare wheel went. This involved squaring up the spare wheel well that eventually frustrated me so much I've cut it out with an angle grinder and I'm building a sheet steel box to replace it. This way, the original plastic insert will fit under the floor so I can carry the spare wheel, jack and plug in cord for the fast chargers.
The 55Ah LTO cells can be charged at 10CA if you really want to, that's around 6 mins from fully discharged to fully charged, but I doubt I'll ever be in that much of a hurry, 2CA would be 110 amps and recharged in 30 mins, I'll be happy with that.
The other advantage is no more NiMh battery and the battery being full after a bit of down hill regen, the best regen I've seen on my scan gauge is 150 amps so a flat battery could handle 20 mins of constant regen .... that's a very long hill :lol:

I also have a Hymotion conversion that is still going strong. I have had mine since 2009 and 35k Mike's. It sitting at 174k. It's been a daily driver 5 days a week. I don't have any technical data. It used to do 30 or so miles before shutting down on flat ground at sea level where it spent most of that time for the last few years it has been in Denver and these days on my commute it shuts off after about 11-12 miles. I never had a problem with the system still works every time. Very happy with the investment back then. Glad to hear other units still kicking it .
