Engineering Support: Maintenance & Battery Warranty
BOOANT Engineering Support Hub
From first install to warranty claim, we provide technical support for maintenance, diagnostics, and warranty. Send a full BMS report first, so we can diagnose without guessing.
Warranty at a glance: 24 months, 50G 600 cycles, 50S 500 cycles, whichever comes first. SOH 70% to 100% is normal, below 70% within limit may be a claim. Claim must include a full BMS report. Warranty covers the battery pack itself, not the charger.
Maintenance
Proactive care to help your high-kW pack last.
- • Monthly cell voltage checks via Smart BMS App, look for large cell differences.
- • Terminal inspection for oxidation, loose connections, or heat discoloration.
- • Charge in a ventilated area, away from flammables, check charger and cable for damage.
Diagnostics
Quick fixes for common high-performance issues.
- • Troubleshooting BMS trips, send full BMS report, including cell voltages, SOH, and trip history.
- • Voltage sag analysis at the same current, sag under load alone does not mean a fault.
- • Regenerative braking adjustment, regen must stay below BMS charge limit, not discharge limit.
Warranty
Transparent coverage for your engineering components.
- • Manufacturing defects, including BMS and MOSFET defects, within 24 months and cycle limit.
- • Cell defects where SOH is below 70% within limit, with a full BMS report.
- • Process: Diagnose → Remote Review → RMA, with full BMS report before RMA.
Warranty Policy Overview
BOOANT provides a 24 month limited warranty on custom packs, 50G 600 cycles, 50S 500 cycles, whichever comes first, covering manufacturing defects and cell degradation below 70% SOH within limit. SOH is read from the BMS at full charge and normal room temperature, 70% to 100% is normal performance, not a defect. Warranty does not cover unauthorized modifications, opening the pack, user-caused shorts, water damage, or charger failure, as warranty covers the battery pack itself only.
