Old electric vehicle battery upgraded for $5,000, doubling its range!

The battery upgrade kit, valued at around $5,000, increases the i3’s 30-40 kWh energy storage capacity to 54 kWh, boosting the range to nearly 400 kilometers.

Such upgrades are quite common in China. For the BMW i3, importing this kit from China now makes it possible to refurbish the vehicle at a very affordable price.

With advancements in battery technology, the availability of such 'aftermarket' battery kits and businesses specializing in battery upgrades is expected to grow in the future.
