The long-term feedback you’ve been waiting for is here!

2.5 years and over 100,000 km after upgrading this Leaf from 24kWh to a VIVNE 62kWh battery.

Here are some of the numbers:

Ahr: 180.0 Ah → 179.87 Ah

SOH: 100% → 99.93%

Hx: 97.66% → 97.59%

Cell voltage difference: 18 mV → 13 mV

Mileage: 205,614 km → 307,629 km

DC fast charges: 109

AC charges: 689

The car has now driven 102,000+ km with the VIVNE battery, and the owner recently drove it another 2,200 km from Dalian to Hubei. Video in the comments.

Can a Nissan Leaf Use Sodium-Ion Batteries?

This is a question we've been receiving more and more from Nissan Leaf owners, especially as sodium-ion battery technology continues to attract attention.

In this video, we explain why we currently don't use sodium-ion cells for Nissan Leaf battery upgrades — and the answer is more complicated than simply changing one type of battery cell for another.

The Nissan Leaf's entire high-voltage system was designed around NMC lithium-ion batteries. The voltage platform, BMS, charging system, motor controller, and vehicle control strategy are all designed to work together.

Sodium-ion cells operate at a different voltage range, and the original Leaf BMS was not designed to manage their different charging and discharging characteristics.

So why can't we simply add more cells to compensate for the lower voltage?

And what would actually happen if we tried to use sodium-ion cells with the original Leaf BMS?

We explain all of that in this video.

At the same time, we don't believe sodium-ion batteries are a bad technology. Quite the opposite — we believe they have great potential, especially for energy storage applications.

VIVNE is closely following the development of sodium-ion technology and exploring how it could be used in future energy storage products.

For Nissan Leaf upgrades, however, high-quality NMC cells remain the most mature, reliable, and balanced solution at this stage.

Your Nissan Leaf may be getting older, but that doesn’t mean it’s ready for retirement.

Sometimes, you don’t need a new EV. You just need a new battery.

Have you ever seen this warning on your Nissan Leaf?

Have you ever seen this warning on your Nissan Leaf? Before calling a tow truck, you may be able to diagnose the problem yourself with LeafSpy. We explain how to check the battery, read error codes, and what P0AA6 means. Video in the comments below.

A complete DIY Nissan Leaf battery upgrade story

If you're considering installing the battery yourself, I think this video could be really helpful. This lear owner completed the installation at home and documented the entire process, including detailed testing and LeafSpy data. I think it's a great reference for anyone planning a DIY installation.

Looking for Nissan Leaf installers in Gladstone, MO 64118 and Florida!

Hi everyone, Cora from VIVNE here, we're currently looking for someone who can help install a Nissan Leaf battery for two Leaf owners, one in Gladstone, MO 64118 and another in Florida.

The battery is a complete plug-and-play pack, so the installation is very straightforward, just remove the old battery, and install the new one. If you own a workshop or have experience working on Nissan Leafs and would be interested in helping, we'd really appreciate hearing from you. Please leave a comment or send me a message. I've posted the installation video in the comments so you can see how simple the process is.

Thank you in advance!

Can We Build a Bigger BMW i3 Battery? Here's the Truth

Can VIVNE build a bigger battery for the BMW i3?

Absolutely.

The reason we currently offer a 45kWh battery is not because we can't build a larger one. It's because we carefully balanced structural strength, battery weight, safety margin, and long-term reliability.

A larger-capacity battery is possible, but it may require compromises in some of these areas.

So we'd like to hear from BMW i3 owners:

Would you choose more range if it meant making some compromises in weight, structure, or safety margin?

14 Months Later — 50kWh Upgraded AZE0 Leaf Still Performing Excellent

Just received an update from a customer in Spain around 14 months after upgrading his AZE0 Nissan Leaf from the original 24kWh battery to a 50kWh pack.

The battery has now gone through 52 quick charges and 319 slow charges, with 16,871 km driven since the upgrade. Current LeafSpy numbers are still looking excellent: 99.94% SOH, 97.6% HX, and only 18mV cell difference.

Curious what most owners think these days.🤠

So everyone, if your Nissan Leaf only had 100km range left, what would you do?

A — Upgrade the battery

B — Buy another EV

C — Keep driving it

D — Sell it
