NexPower Lithium Battery Replacement

The v hybrid battery is the same as the hatchback. You will have to diy teardown your battery assembly to the cells and replace them.

 

Yes, it works for the Prius v (wagon) model.

There are many threads in this forum about the lithium battery upgrade and user experience with them. You need to search for them.

'doesn't seem to work well anymore', you may have a different problem which a new battery won't solve

 

I have been running the Nexcell Lithium pack since last Summer (June 2022) version 1 (zero problems). Went from 41-42 mpg on a decent stock battery to this and started immediately seeing 51-53 mpg under the same driving conditions. Recently, upgraded to the Version 2. Not a whole lot more MPG, maybe 1-2 more but much more bottom end torque and temperature management with the new circuit boards and vented case tops. Here's a couple screenshots from 1/2 tank and empty recently (Gen 3 engine in car at the time). You can see this car gets WAY more than your average V. I would take the plunge especially with rising gas prices and invest in your future. (Yes that's 425 miles at half tank and yes, that's also 623.5 miles at the end of the tank).

 

Seems your gauge showing over half is slightly off when 8 of the 12 gallons have been used. Regardless, 50 mpg with a heavier v and its higher numerical final drive ratio (3.703 vs 3.268) is impressive, assuming the transaxle was not changed.

 

Transaxle not changed. Also, 1 bar above half is actual half tank btw…

 

Missed that part when I read the manual or over my 12 years and 300,000 miles of driving a v. But if you say so I guess my gauge is calibrated wrong.

 

I have an ultra gauge plugged into the OBD2 at all times that tells me how much gas is left in the tank. I checked it at this mark and it said 5.95 gallons left both by hand and electronic device.

 

I have the NexPower battery in my 2012 Prius v.

 

And?

 

Yes.

1. The research and development is done by YOU.
2. If you consider your wife’s dining room table as your “workbench”, it would be be much better to engage professional assistance and stay the safe road by having “your mechanic” replace it for you using an original one. HOA’s, buying service contracts for everything, landscaping services, etc. Besides you might get something on the driveway and your insignificant other may not approve.
3. Jack is a great guy. You will find much fanboy fawning over him. However he is just a man. And you should be one, too- and not some owned fanboy b!tch.

 

Do not listen to this Ford guy.

Clearly drinking some hateraid by the gallon.

I'd want to know howto use it if I were going to get the lithium upgrade from
Toyota hybrid battery upgrade pack– NexPower Energy

Attention to details when installing or having it installed is a good thing.

 

Hi there, I am having some issues with my NexPower battery installation. It seems to be extremely loose when I torque the pressure bars to spec. They move all over when I rotate the battery to place the sensors back, any suggestions?

 

A 2005 Prius, right?
Some times it helps to read the instructions again.

If you're still not getting the blades in tight you may want to see if there is a Nexcell installer near you or send Jack an email.

You did put the bolts on the bottom of the pack back in, yes?
