Maintenance Tips      

• Match exact specs: Only use true 48V G70-compatible pack—wrong voltage can damage controller or reduce range.
• Check connector type: Confirm plug shape + pin layout before buying (G70 versions vary).
• BMS safety: Ensure replacement has a proper Battery Management System (BMS) for overcharge, overcurrent, and short protection.
• Capacity consistency: If replacing one battery in a dual setup, keep both batteries similar age/capacity to avoid imbalance.
• Balance charging: Fully charge new battery before first ride, then do a few normal cycles for calibration.
• Avoid deep discharge: Don’t regularly drop below ~20%—it shortens cell lifespan significantly.
• Heat control: Never charge immediately after a ride; let battery cool 20–30 minutes first.
• Storage rule: Store at 40–60% charge if unused for 2+ weeks.
• Water protection: Keep battery dry—moisture can damage BMS and connectors even if casing looks sealed.
• Connector care: Periodically clean terminals and check for looseness or corrosion.
• Load awareness: Heavy acceleration, hills, and max speed riding increase battery stress—use moderate throttle for longer life.
• Replacement timing: If range drops ~30% or charging becomes unstable, consider replacement or cell reconditioning.
