Where to get a New Gen 4 Panasonic Module snapped battery post Gen 2 Batt rebuild

Project Lithium modules are designed for ease of repair in mind and it'd be an easy fix. But Toyota modules are the opposite of that.

Creating further difficulty is used Gen4 modules are hard to find and new ones are only sold as complete packs. Perhaps you can sell your Gen4 modules to a Prius C owner who only requires 20 modules rather than 28 and then you'd be the rarest of rare people who has brand new individual Gen4 modules for sale. I'm sure you could charge alot for them and might even be able to recover all of your costs so you can buy another set of 28 modules for your Gen2.

Which brings up the question, where have you found brand new Gen4 packs for sale, without having to provide a gen4 core to get your deposit back? I'm sure lots of people would be interested in that option.

 

Oh good, that's way easier to deal with... You just gotta find another deal like that and then post on here to find people with Prius C who will help you finance it.

PS: your torque settings on your impact driver are messed up.

 

Yeah on reinstallation on a stud that's already had a bolt on it I'd probably knock five to seven inch pounds off of that number just because and then you don't want anything on the stud or the nut that's going to make those torque specs slip lubricant etc It's tricky business that metal going into plastic. You might talk to any of the good quality battery rebuilders like the hybrid doctor he's online and has a physical place of business up in Fairfax VA people like that My battery guy will have one or two modules ready for me balanced and ready to go He's doing 28 or 36 at a time so I can call him today and go pick one up or three up at lunch time if I want can I guarantee they're from a Gen 4 probably not but what he's going to hand me is already balanced to whatever it is $5,500 milliamps and whatever the voltage you're supposed to be I never have to second-guess this guy If I was to get a bad module from him and all this and that there have leaking HV voltage to the frame or any of that nonsense I usually find the offending module or two call him and meet him somewhere and pick them up He's handed me six modules over the few months I've been messing with this one or two other cars not an issue actually he's done me very well.

 

Use the Dr Prius app to take a look at the HV battery block voltages.

 

You need to take screenshots of the Dr Prius with high charging (regenerative braking) and discharging (hard acceleration) amperage when you are driving the car. Then post the screenshots.

 

My battery guy charges me like 550 to swap out a generation two setup It's the best 550 I spend on one of these cars he does great work and all of that anything goes wrong with the battery he'll either come and replace it bring me modules or whatever I want to do so there's always that he's got the equipment to run I think 58 or 60 modules at a time so when you're set up to run like that you know you can make things happen reasonably quick so I think that's the way to go with the refurbed battery business rather than sitting in my basement with hobby chargers and then if I don't do that in the car is worthy of it I buy a real battery from Toyota finding on sale buy it online do all the nonsense and then I know I'm good for close to 10 years if I wreck the car or something happens I make sure I take it with me

 

One of the two modules in block 1 has failed. 1.0-1.5V drop under load pretty much confirms that. Could be the replacement, or not.

It's up to you what you do next. Maybe going into the pack again will buy some time. Maybe it fails again. That's the potential price for a "cheap" repair.

I went DIY when I first got my 2006. Took over a month to cycle all modules with hobby chargers, but it was "good" for 50k miles.

The next time it hiccupped, I put a new OE pack in.

Apparently there's nobody here selling them and I don't know why they would be here they would be hoarding them for their car next project whatever like car people do You need to be getting online and talking to big big big auto salvage operations like the ones down in Conyers Georgia they are big If you ever see some of these places well we won't even go into that anyway That's the place is you're going to need to be talking to to find these 2019 to 2022 wrecks and then there's a lot of people in line before you that are all vying and trying to buy this same crap to resell to us I know people in my area that go around to LKQ and just rip break actuators and MFD displays out of generation twos to put them on eBay for exorbitant prices but I don't even think anybody ever pays or buys but they're doing that with so much of this stuff You know they can make a few bucks to keep up their other habits or whatever they got going on but that's how petty this stuff is it really is really petty I know guys that'll go out and go to LKQ and other smaller operations and just destroy things while they're out on the yard just so nobody else can get them yeah I'm telling you man it's like that real nice person hats.

 

The first thing to do is check the voltage sensing wire harness that connects to the battery ECU. Check the connector for any corrosion. This is a very common problem on a gen 2 Prius. If that checks out okay, then you need to determine which module in block #1 is bad. Is the bad module the one that you purchased? If so, contact the seller and request a free replacement.
