• Charge the 48V 16Ah battery in a cool, dry place and avoid heat above ~40°C to prevent cell degradation and capacity loss.
• Keep daily charge levels between 20–80% to maximize lifespan and reduce long-term battery wear.
• Avoid full deep discharges (0%) as they stress lithium cells and shorten cycle life.
• Do not leave the battery plugged in for long periods after reaching full charge—unplug when fully charged.
• Let the battery cool ~20–30 minutes after riding before charging to avoid heat-related damage.
• Always use the original ENGWE charger to ensure correct voltage and protect the BMS system.
• Store at ~40–60% charge if unused for long periods (2+ weeks) to maintain cell health.
• Keep battery contacts clean and dry to prevent connection issues and power drops.
• Avoid water exposure and high-pressure cleaning around the battery housing and terminals.
• Check battery mounting rail regularly to ensure firm locking and prevent vibration damage.
