One lithium battery 12v in a small case .
1. My battery pack stopped charging, what should I do?
A :Often if this happens it is due to the anti-spark feature built into the BMS. Say you did not properly make a connection somewhere and the wires sparked, the BMS would shut itself down to prevent damage to the system. If this happens the first thing you always want to do is to try resetting the BMS by using your charger to try charging through the discharge connector for a few seconds, maybe a minute. You just run a jumper (basically regular wires) from the charger's connector to the battery's discharge contact, making sure you go positive>positive and negative>negative.
2. How do i know when it is fully charged?
A: If your battery has a voltage display on it then you can tell that is fully charged based on the voltage readout, You can also test the voltage with a multimeter directly from the discharge connector.
3. Do you offer charger for battery?
A: Yes, we do
4.what's your MOQ ?
5. can i get a free sample ?
A: sample is fine , free sample you are thinking to much .
