Can you provide the datasheet of the BMS before sampling ?
No , but we can provide it after samples completed.
No , but we can provide it after samples completed.
If customer need, the lithium battery pack can be built in BMS according to device parameter.
Normally ,the discharge current of most 3.7v lipo battery is 0.5C discharge ,but some special lipo battery has high discharge rated ,we can provide the 1C discharge lipo battery if customer need.
The discharge temperature should be between -20℃ to +60℃.
We can check the appearance of the lithium battery first ,there shall be so such defects as followings,which may adversely affect commercial value of the cell.1.Scratch2.Rust3.Discoloration4.Dirt5. Deformation 6.Leakage
The cell should not be used with other cells having a different capacity ,chemistry ,or manufacture. Doing so could cause the battery to generate heat,smoke,catch fire,or explode.
The recommendation is SOC 10~50% for long-term storage
Usually, the battery condition at shipment SOC (State Of Charge ) not exceed 30% of rated capacity
If you don’t use the battery for a long time , you should better remove the battery to dry condition of low humidity. Even though the device has been turned off , the battery still will consume some current ,it will shortens the working life of the battery.
Our MOQ for power bank is 500pcs.
Yes , we can provide if you need .
1. application 2. working voltage range 3. max continuous current and peak current 4. max battery size
After charge, tested the batteries' initial state and capacity. Charge to 10.0V at 3C current, then charge to 0.01C at CV mode.Observe changes in battery appearance.
Yes, we can produce by your samples or technical drawings.
