What's Covered
The following are covered under warranty across all our battery products, subject to product-specific time periods listed above.
Cell & Capacity Performance
Battery cells are covered against premature capacity loss and cell failure under normal usage conditions. Coverage includes:
- Abnormal capacity degradation beyond expected curves
- Individual cell failure or imbalance
- Manufacturing defects in cells or assembly
Battery Management System (BMS)
The factory-installed BMS is covered against firmware faults, communication errors, and protection circuit failures during the warranty period.
Service & Diagnostics
Free technical diagnostics, cell balancing, and BMS service are included during the service warranty period for all eligible products.
Water & Splash Resistance
EV bike and select battery enclosures are engineered to be water and splash resistant for daily use in light rain. Note: they are not waterproof — see exclusions for damage caused by immersion.
Warranty Exclusions
The following situations are not covered under any warranty period. These exclusions apply across all battery product categories.
Water Immersion Damage
Warranty is void in case of damage caused by water immersion, flooding, high-pressure washing, or prolonged submersion. Splash resistance does not equal waterproofing.
Physical Damage & Impact
Warranty is void if the battery shows signs of physical damage, including:
- Dents, deformation, or crushing of the casing
- Cracks, fractures, or punctures of the enclosure
- Damage from drops, falls, accidents, or collisions
- Internal damage caused by external impact
Unauthorized Charger Use
The battery must only be charged using the charger supplied or approved by Hybrid EV Engineering. Use of any third-party, modified, or unapproved charger immediately voids the warranty — even if no visible damage has occurred.
Modified Factory Settings
Batteries are delivered with factory-configured BMS settings, voltage, and current parameters optimized for safety. The following void warranty:
- Tampering with or reprogramming the BMS
- Changing voltage, current, or temperature thresholds
- Opening the casing or breaking factory seals
- Unauthorized cell replacement or rewiring
Electronic Accessories
Warranty does not cover external electronic components or accessories, including:
- Charger units and charging adapters
- Display panels and digital meters
- External wiring harnesses and connectors
- Inverters, controllers, throttles, and motor accessories
Improper Use & Installation
Damage caused by improper installation, use beyond rated specifications, exposure to extreme temperatures, short-circuiting, or use in unintended applications is not covered.

General Conditions
Documentation Required
All claims must be accompanied by the original warranty card and proof of purchase. Claims without valid documentation may be refused or require additional verification.
Non-Transferable
This warranty is issued to the original purchaser and is non-transferable. It does not transfer to a new owner if the battery, scooter, or vehicle is resold.
Final Decision Authority
Hybrid EV Engineering reserves the right to make final determinations on claims based on technical inspection findings. Detailed reports are provided for any rejected claims.
Replacement Terms
Approved warranty replacements do not extend the original warranty period. The remaining warranty on the original battery transfers to the replacement unit.
