How To Find
the right deep cycle battery?
We provide 24 hours online service. Any interest, please contact service@osnpower.com for support and more information, our professionals will reply you ASAP. OSN POWER will provide you with a variety of lithium deep cycle batteries. We're here to help you find the right battery.
Features:
• IEC Certification on the combination of BMS and individual cell for complete safety peace of mind
• High energy density (less than half the weight of SLA) lowering total weight of application
• Fast recharge, battery is charged and ready to be used sooner
• Flat discharge curve, longer run time and more efficient use of capacity
• Extremely low self-discharge rate, can sit unused for longer periods of time
• Large numbers of cycles >2000 (100% DoD), up to 8 times cycle life of SLA lowering your total cost of ownership
• Safe and stable chemistry and integrated BMS, the use of LiFePO4 along with integrated BMS ensures protection against over charge/discharge, temperature and short circuit providing the highest degree of safety.
• Bluetooth versions available, monitor the health and state of your battery from your phone
• Greater capacity utilisation 60% more than SLA, gives longer runtime than equivalent SLA
