A longer cable can be included so you can connect it to your own connector. 3. Check the dimensions. If they are critical, please consider this. 4. The amperage determines how long your battery will last with your device. The higher the amperage, the longer it will last. I have batteries in different amperages; please check my other listings. 5. I assemble the batteries myself. I install the batteries or pack, the protection device (BMS), the connector cable, and the insulating PVC material, along with a label indicating the correct voltage and current.
