La batterie lithium-ion Booant 72 V 35 Ah est spécialement conçue pour la moto électrique tout-terrain EBOX. Elle utilise des cellules Samsung 21700 50S d'origine. Elle offre plus de 800 à 1 000 cycles de charge/décharge, garantissant une autonomie longue durée.

Cette batterie est équipée d'un système de gestion de batterie (BMS) Bluetooth intégré, permettant de surveiller en temps réel la tension, la température et la capacité via une application mobile, ainsi que de fonctions de protection contre les surtensions, les surintensités et les courts-circuits. Elle prend en charge la charge rapide lorsqu'elle est associée à un chargeur rapide.

Il prend en charge plusieurs connecteurs de décharge (QS8/10, Anderson, XT90F/M, câble uniquement) et options BMS (80 A pour les moteurs 72 V 4800 W, 100 A pour les moteurs 72 V 6000 W). C'est une solution d'alimentation fiable pour les vélos électriques EBOX.

Important Notes

  • Optimal State of Charge (SOC): Maintain 40-60% (3.7-3.8V per cell)
  • Prohibited States: Avoid long-term storage at <10% or 100% SOC (accelerates aging)
  • Temperature Control: 15-25°C is ideal environment (<2% annual degradation)
  • Permissible Range: -20~45°C (requires SOC control)
  • Strictly Prohibited: Above 50°C or below -20°C (hazard risk)
  • Physical Protection: Avoid compression/impact (even with ABS casing)
  • Short Circuit Prevention: Keep away from metal objects to prevent short circuits

Storage Recommendations

For long-term storage (>1 month), perform periodic brief charge/discharge cycles to maintain lithium-ion activity and ensure normal energy output. We recommend performing a shallow cycle (30%→80%) every 3 months.
