Installed New Nexcel Battery now Have RED Triangle, no codes on scanner. Help !

Did you get a battery failure code before you installed the battery for 2005? The red triangle can mean many things, not just a battery failure

 

Corrosion in the voltage sensing harness and ECU could be the problem... Did you clean and replace most of it?

Also the most common problem is this:



If that turns out that's the problem you'll need to disconnect the 12v for a few minutes to clear the code if it's not showing up in your code reader for clearing.

 

The voltages aren't the same according to the photos you have, but you're going to need a P3000 to prove manufacture defect. Maybe try Car Scanner App, Dr. Prius App or Toyota Techstream to get error codes?

 

You are just guessing what the problem could be. If you have the RED triangle, you have trouble code(s). You need a better scanner to retrieve them. Take a look at this thread: https://priuschat.com/index.php?threads/232741/

It's worth a shot... So far Project Lithium has been able to afford to be generous in the warranty for issues with bad packs caused by a lack of cleaning up corrosion, but their warranty clearly states its not covered and during times of hot weather when the most warranty claims come in, you might have an issue. At the very least they'll ask you to send pictures of these cables to ensure they're clean or replaced before deciding how generous they can be and it's mostly an issue for people who drive way too long ignoring/clearing the red triangle that destroys a pack, not a brand new pack with an issue. But again, we don't know what the error codes are yet, so it's just guess work at the moment.

 

I wouldn't show pictures of connectors like that to anybody not even myself that should have never ever been reused for at least been glass beaded or something but if that's the wire I'm thinking it is it's probably black halfway through if not from end to end from heat most of them are that I see I guess this is a thing. Maybe we can come up with a better wire or something for that or those two connections or whatever needs to be done

 

That cable isn't great, but it's not significant to your problem. If it was, then you would have heat damage from high current through a high resistance cable (along with voltage drop and the related code).

Do I assume that you cleaned or replaced the busbars and torqued all connection hardware to specification with a torque wrench? (48 inch pounds- if Nexcell uses the same hardware as OE)

Does you Innova display results from 15-16 system on your Gen2 when you perform a "system scan"? If it just says "no codes found" then it is likely not fully capable to diagnose your fault. See the link posted above.

That said, having block 10 showing 1.0V lower than the others isn't good. If that block is consistently low when discharging then the battery ecu would set codes. (usually voltage difference is 0.3V or less)
