THIS OFFER IS EXCLUSIVE TO EXISTING CUSTOMERS
We introduced the sodium-ion battery in 2023, and after two years of real-world challenging, it has proven to be incredibly durable—far more resilient than lithium-ion batteries or stock NiMH batteries.
To survive the financial hardship and show our appreciation to early customers who helped lead the sodium-ion revolution, we're offering a replacement program to upgrade your aging (and possibly failing) lithium battery, this limited-time offer is to ensure our company's continued operation.
You do not need to return anything, simply purchase the replacement program that essentially cover the tariff and all the shipping fees. (shipping fees include oversea freight + domestic shipping)
PS: This replacement program DO NOT extend your warranty further, the money is paying to government and shipping companies, we simply want you to get back on the road with the least amount of money.
Additional Information
