The Most Advanced Lithium Hybrid Battery Upgrade Is Now Here

After 8 years of dedicated research, development, and rigorous testing, Nexpower is excited to offer the solution for your aged and failing nickel metal hydride (NiMH) battery. Nexpower's advanced lithium iron phosphate (LiFePO4) hybrid battery modules replace the traditional nickel metal hydride modules thus elevating the performance of your hybrid vehicle.

If you are experiencing decreased capacity, poor fuel economy, warning lights, diminished power and trouble codes, look no further! NexPower replacement modules offer a cost effective solution that provides more power than your stock battery and better efficiency with the best live vehicle performance data on the market when paired with the Dr. Prius app.

6 Benefits of Lithium Power

Cost-Effective Replacement

Nexpower's lithium upgrade modules offer a more cost-effective solution than replacing the OEM battery. By only swapping out the modules, you utilize the battery case that your vehicle came with. And no need to worry about core charges and wondering when you'll be reimbursed!

Enhanced Power and Improved Fuel Economy

Nexpower's lithium battery modules deliver an average peak power of 260Amps, compared to the 150Amps peak power from the standard NiMH battery giving you 110% more power right out of the box.

Improved Fuel Economy

Nexpower's lithium battery modules maintain optimal voltage to encourage the vehicle's computer to favor electric power, resulting in enhanced fuel economy.

Weight Advantage

The typical hybrid NiMH battery weighs roughly 80 lbs. Nexpower's lithium pack, on average, weighs less than half of your OEM pack, presenting a significantly lighter alternative.

Highest Level of Safety

Rigorously tested in extreme conditions worldwide ensures safety and reliability. For detailed test and installation videos, search for "Dr. Prius lithium test" on YouTube.

Toxic Free Solution

Nexpower lithium battery upgrade modules are an environmentally conscious, toxic-free alternative to your OEM battery. Therefore eliminating the emission of hazardous chemicals like KOH. No spilling or harmful vapors, skin irritation or other issues that are present with NiMH batteries.

“Wanted to let you know the Nexcell battery worked like a charm. My Prius is better than I've ever experienced. It seems like I can't drain it to 0%, even if I tried. - PriusChat.com

Finally got to California and tested pack over Siskiyou pass... It's a totally different car at the highest elevation of I-5 when it's down at 2-3 bars. Still lots of power! So much different than a worn out NiMH that runs out of power and the engine needs the accelerator nearly floored with no speed or power to keep going. I was so impressed my first thought is you should brand it as such. Call it the "Hill Climber Lithium Power for Prius" Rush hour in Portland in EV mode was almost as awesomely impressive as well - YouTube

First time hitting 3 miles on pure EV mode, incredible, car drives like new and accelerate faster then new. Thank you Dr. Prius
