Discharging performance under room temperature
Discharging Capacity：
Discharged at 285A≥285Ah
Discharge capacity at 285A:
It’s the capacity (in Ah) when the battery is discharged to 2.5V at 285A at 25±2℃.

Discharging characteristics under high and low temperatures
Discharging Capacity：
a) Discharged at 55℃≥98% initial capacity；
b)Discharged at -20℃ ≥70% initial capacity；
Discharge capacity at high-temperature:
a）Standard charge；
b）Be set aside for 5h at 55±2℃;
c) Discharging the battery to 2.5V at 285A at 55±2℃, calculate the capacity.
Discharge capacity test at low-temperature:
a）Standard charge
b）Be set aside for 24h at -20±2℃;
c) Discharging the battery to 2.5V at 285A at -20±2℃, calculate the capacity

Rate charge Performance
Capacity≥97% initial capacity；
a）Under room temperature, discharge it at 285A to cut-off voltage 2.5V；
b）Under room temperature, charged to 3.65V at a constant current of 570A, and then, changed continuously with constant voltage of 3.65V until the current was not more than 3.75±0.5A. Put aside for 1h；
c) Under room temperature, discharge it at 285A to cut-off voltage 2.5V；
d) Calculate recovery capacity (in Ah).
There is no doubt that choosing LFP is the most cost effective, environmental way.

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

Attentions：
For safety usage, please be careful on below：
Warning!
1. Do not immerse the battery in water and keep it dry when not in use;
2. Do not knock, throw or affect the battery near a fire source or under extremely hot conditions;
3. Please charge according to the charging requirements;
4. Do not reverse the positive (+) and negative (-) terminals;
5. Do not short-circuit the battery by connecting wires or other metal objects to the positive (+) and negative (-) terminals;
6. Do not directly weld the battery terminals.
