Toyota Prius Hybrid Battery Module - Replacement HV Module Pack for Toyota Prius Camry Nissan Altima Lexus GS450H Lexus LS250H Chevy Tahoe HEV Chrysler Aspen Hybrid

Slightly different than the other modules in my 2006 Prius, lighter color and was a hair taller, but it fit and worked perfectly. Tested without a load at 7.9v. Since my other modules had an almost identical voltage, I didn't test the new module under load, charge & discharge any modules, or balance the pack, which is all highly recommended (many even say necessary). Call me rushed and reckless, but as soon as it was reinstalled, all warning lights on the dash were gone!I read that you can "force balance" the pack by getting it full then leaving the car off for 12 hours. This is supposed to be done 3 times in a row, but who has time for that? I've already missed several days of work (delivery driver). Despite not following most of the recommendations, everything seems to have worked out great. It wasn't exactly easy, but it was also nowhere near as hard as some made it seem.The one negative review suggests that this module from Shengdida Tech has more resistance and less heat dissipation, suggesting that it may not last long, so if this module does fail within the next year for any reason, I'll be sure to log back in here and update this review. For $36, even if I have to do it again next year, it's still waaaayyyyy better than paying thousands at the dealer!

I purchased 28 for my Gen 3 Prius. 3 of them arrived with between 5 and 6 volts, all the others were between 7 and 8 volts. They all have the same model number printed on them, and don't have serial numbers so it's a crap shoot regarding manufacturer date. Some appeared to have lighter print ink for the model numbers, which makes me think they are not from a similar production batch, but really who knows.I tested one of the low voltage modules with an IMAX B6 hobby charger set at 6A charge, 2A discharge, default deltaV, no time limit, and 7500 mAh charge limit. Discharging down to 6V returned over 6800 mAh so I recharged it a bit and put all of the modules into my Prius battery pack.I had trouble getting them to fit well, it's hard enough for me with genuine modules, but for some reason these were worse. They are a little taller, however I don't think that is the problem. Their plastic feels less substantial, and they're not as well made as genuine modules...Also the pressure release vales appear to be screw on (Allen key) , I didn't test whether or not they could be easily unscrewed and removed (perhaps to re-hydrate)... I will when one fails.After getting them reinstalled in the vehicle I grid charged with a Prolong charger for 16 hours, let them rest for several hours then before testing.. seat of the pants feels great. However after testing with the excellent Android Hybrid Assistant app, it's evident that the pack isn't well balanced. I'll try a full Prolong re-conditioning in a few weeks and see how they fare.Bottom line is for less than I can get small quantities of these new Chinese modules direct from China, and considerably less than a new Toyota pack, my Prius is getting 23.1 km/l (mostly city driving), and no more triangle of death "P0A80" DTC.they are missing the metal foil of the genuine modules, so I expect them to run hotter, and use Hybrid Assistant to override the Toyota default HV battery cooling fan algorithms to aggressively cool the pack... so far I've not seen worrisome temperatures, and I live in the tropics.

my Prius repair after the dreaded triangle of death emblem from traction battery failure, was less than 100% successful, i suspect more from just installing 3 battery modules and not taking the time or effort to make sure that the 3 new battery modules were of similar resistance to the the original 25 battery modules and balancing all 28 modules to within specific voltages. As a result my mileage has been reduced from 42 mpg to 40,5 mpg because the battery pack does not recharge as quickly as before and does not engage the electric traction motor as robustly as before the battery failure and my repair. But wait, I'm now driving my car with $100 worth of batteries and about 8 hours of tinkering around, versus at least $1300 for a rebuilt battery with horrible reviews and installing myself, $1500 and 1 yr warranty if i drove 150 miles to a larger city or $2500 in my local town or $3500 from Toyota for a 5% reduction in fuel mileage (increasing my fuel consumption approx. 20 gallons a year) because i just slapped the batteries in and started driving.

I can pretty much strip out the whole car interior for access to the battery pack by myself. The weight of the pack makes removal from the vehicle a two person job though. Remove the outer cover and remove all the battery interconnections as shown in Youtube videos or instructions. Write the numbers 1 through 28 on notepaper. Test the voltages on each of the 28 modules. Since the polarity placement on each module reverses each module, a digital meter is a great help since you can just read the positive and negative resulting voltages without moving the leads back and forth. My pack had every module reading 7.8 volts ( depending on how long the vehicle was parked) except for module 21 which was 6.51 volts which indicated a single bad cell in that battery. I installed the replacement module and reassembled the battery pack then I reset the Prius error codes and gave the car a test drive. Car is back to normal and run for more than 1000 miles now.

Module arrived on time and loosely packaged.This is a Chinese aftermarket copy of the OEM Toyota hybrid battery module. The cells have only one connection point between cells leading to increased internal resistance, Furthermore their is no foil thermal layer to help dissipate the increased heat that this module will produce.After cycling the module several time I got a maximum of 5.635AH out of it.Would not recommend this module for use in a prius battery pack but I had no other choice but to use it.UPDATE: after running it in the car for two months the triangle came back up and guess what? It was this very same module. It had overheated and swelled up damaging the modules next to it.These are Chinese junk.Stay with an OEM module.

One of my cells came in at 6.7volts, took a while to start the repair, was shocked to find a “new” cell was testing at 6.7 volts without being used a few weeks later.

If I could give them zero stars I would I expected for this arrive well as I’ve been counting on two weeks to be able to fix my Prius these two individual modules read even more...

Ok

For a 2006 Prius. I bought these as an alternative to the questionable products being sold by HV Hybrid Parts (which I have had MANY bad units and had to return).

Voltage was perfect. Replaced bad cell and worked great, very happy with these hybrid battery new cells.

Saved thousands over the stealerships! Highly Recommended BATTERY PACK. Got the 2 of death on my 2007 Prius.
