For Sale 2015 Battery Module Pack $1250 Columbia, SC

Ok, this is an update 12/8/2016. I extremely surprised no one has jumped all over this, as it's a pretty good deal, including the offer to help swap if needed. This pack will act as a direct replacement for any 2004-2009, providing a complete update to Gen 3 modules removed from a 2015 wreck. I'll wait until Dec 15, then she's being parted out. Thanks for looking.

This is a 28 module pack from a wrecked 14k mile 2015 Prius. I purchased the complete hybrid battery from a recycling yard over the summer. I disassembled the battery to use the module pack for some comparison testing between new modules and older modules, with the intention of either installing it in my car's battery, or parting it out. I don't need to install it, so I'm going with parting it out. Prior to doing this, I'm going to offer the 28 cell assembly for sale in case someone wants to give their car a complete module update. All 28 modules were cycled using Hitec X4 AC+ chargers using 1.5 amp charge/1 amp discharge settings. All modules showed to have >6700mah capacity at these settings. All were load tested at 50 amps using a TENMA model 72-7680 programmable electronic load. The date codes on the modules show a manufacture date of 04XP = October 4th, 2014

I own two 2005 Prii. One had a battery failure, so I purchased two 2013 Prius C hybrid batteries (only 20 modules per battery) and used them to update that car. It has run flawlessly ever since (30,000+ miles). If you're interested in doing the same, this pack is what you need.

The photos show the module pack when it was initially removed from the hybrid battery (you can see broken glass still near the cooling fan). One photo shows serial numbers. One photo shows the cells as they are right now, with equalizing being performed. The testing was completed last week and I installed heavy gauge copper wire to the terminals to equalize all voltages in case I decided to install it in my car.

If this is something you're interested in, but not confident in your mechanical/electrical abilities, I can also help with the swap. I have 30+ years experience in both areas. You bring a battery, we can toss it on the work bench and take care of business.

I'm in Columbia, SC.

 

I'm not quite sure about what you're trying to tell me, but the balanced part is accurate, as all 28 modules tested in the 6700-6900 range using the settings noted in the original post. The pack was from a 2015. The date code on the modules is late 2014. I have the receipt and VIN if a buyer desires to see it. The 28 cells were cycled using 3 chargers, so they were done as 12, 12 and then 4. Once the last charge of a set was complete, the Hitecs were moved to the next set. The previous set modules immediately start drifting down to their non-charging equilibrium voltage. This was done over a couple days, so the final set of 4 has a higher voltage than the second set of 12, which has a higher voltage than the first set of 12. Over several days, all 28 may equalize to within a few tenths of a volt of each other. I typically let them sit for a day or two after the final charge and then use the wire to get it done much faster and to the same exact voltage.

 

I am absolutely amazed by Gen 3 modules. I just disassembled a 54k mile 2011 Battery Pack to start testing the modules. It was purchased over 6 months ago and has been sitting in the shop ever since. It was from a wrecked car that went through the typical wreck/insurance/auction procedure, so who knows how long it's actually been sitting idle. All 28 modules are still 7.57 to 7.59 volts. I'm putting them through the same exact procedure as the 2015 pack. Will be interesting to compare the results.

 

No, I'm not a repair shop. I'm just a hobbyist. I've been fortunate enough during my life that I've become well educated and experienced in electronics, electrical and mechanical skills. I have a real job, but also have several hobbies that I work on in my spare time, Unfortunately, most of what I enjoy doing isn't what many consider to be a hobby. One is that I rebuild/refurbish automotive electrical motors, another is that I enjoy exploring salvage yards, and my most recent is now Prius hybrid batteries. They kind of all tie-in together.

 

I don't yet have a "set in stone" procedure for the load test. I tried several methods. My previous electronics/electrical training&experience has made it very easy to distinguish between a good and bad battery. The programmable electronic load can be set for any value between 0 and 60 amps. I have a set of power cables to connect the module to the TENMA and the programmed load is applied at the push of a button. I use a Fluke 115 to monitor voltage at the module terminals and the TENMA displays the voltage at the load. I use it on constant current mode, so the TENMA will maintain that current as long as I want or until the module is depleted. I'll try to write more later. The website lag is horrendous. I keep getting warnings that priuschat is not responding. It's very hard to write when the letters appear on the screen 5 seconds after typing. Driving me crazy. Type a few words and then wait and watch as one letter at a time slowly appears. I'll be back later.
Ok, it's later and the lag seems better. The module voltage will experience an instant voltage drop depending on the load applied. The voltage will then continue to decrease as current is drawn. Using the 2015 modules nvm,,,,the lag is back

 

Also, I ran across a GEN 1 battery pack that was built in 2015 with December 2014 date codes on the modules if anyone is interested. Again, not some half baked mixture of modules, but a factory replacement GEN 1 battery assembled in 2015 ("S" code) with Dec 2014 serial numbers on the modules. Removed from a front collision wreck.
