✅ The BMW i3 battery upgrade effectively enhances driving range, continues to use the original BMW i3 BMS, and does not impact power performance, while charging time increases moderately.

✅ After the battery upgrade, the original voltage range is maintained, ensuring that the vehicle’s electronic systems (ABS, ESP, onboard computer, etc.) remain unaffected and function normally.

✅ The BMW i3 battery pack is protected by a CFRP frame, and upgrading the battery does not change its mounting position or impact protection structure, ensuring that vehicle rigidity and crash safety remain unaffected.

✅ Yes, the upgrade is possible. We will ship a pre-programmed 120Ah/154Ah SME to the customer for direct replacement of the original vehicle’s SME. Once the new modules are installed, no additional software adaptation or upgrades are required, and the vehicle will function normally.

✅ You need to go to a third-party workshop for the upgrade. BMW dealerships typically do not offer battery upgrade services and only support original battery replacements, which can be costly.

✅ A professional third-party workshop can install the 120Ah/154Ah battery following our installation guidelines. Once installed, the battery will function immediately without additional software adaptation. The workshop only needs to ensure proper installation and confirm the safety of the high-voltage system.

✅ Our battery operates under the original BMS management, meaning it will function normally once installed correctly, ensuring full compatibility with the vehicle’s system.

✅ In most cases, a battery upgrade does not affect insurance claims, as it does not alter the vehicle’s core safety structure, and insurance companies will process accident claims as usual.

✅ However, in the event of a total loss claim, the insurance provider will not cover the new battery separately. Instead, the payout will be based on the vehicle’s original factory-labeled value in the second-hand market, not the upgraded battery’s value.

✅ It is recommended that owners consult their insurance provider when purchasing or renewing a policy to clarify specific terms and ensure compliance with insurance requirements, avoiding potential disputes.

✅ Upgrading the battery is significantly cheaper than buying a new car.

• A new electric vehicle (e.g., BMW iX1, Tesla Model Y) typically costs $40,000-$60,000 USD, while upgrading to a 120Ah/154Ah battery is a much more affordable option that extends driving range.

✅ Battery upgrades effectively extend the vehicle’s lifespan.

• The BMW i3 features a CFRP (Carbon Fiber Reinforced Polymer) chassis, making it highly durable. With a new battery, the vehicle can continue to operate efficiently for many more years, avoiding the depreciation costs of a new car purchase.

✅ Buying a new car may come with additional costs.

• Higher taxes & insurance fees: A new car purchase may involve increased registration fees, higher insurance rates, and possible sales tax.
• Charging compatibility issues: Some newer models require higher-power charging stations, which may necessitate upgrading home charging equipment.

✅ A battery upgrade allows you to retain the BMW i3’s unique driving experience.

• The BMW i3 is well known for its lightweight design, rear-wheel drive, and efficient electric motor. By upgrading the battery, you can continue to enjoy the car’s unique driving dynamics without adjusting to a different vehicle.

✅ Slight Weight Increase,But Minimal Impact

Compared to the 60Ah battery, the 120Ah battery is slightly heavier, but thanks to the BMW i3’s carbon fiber reinforced polymer (CFRP) body, the car remains lightweight. Acceleration and handling experience minimal changes.

✅Charging Time Changes

A larger battery capacity slightly increases charging time, depending on the charging method:

• Household 220V socket (2.3kW): Charging time increases from 8-10 hours to 12-14 hours.
• 7kW Wallbox (AC 7.4kW): Charging time increases from 3-4 hours to 4.5-5 hours.
• DC 54kW Fast Charging (10%-80%): Charging time remains approximately 40-50 minutes, and the upgraded battery still supports fast charging.
