This one may be too big. You need to measure the space first. **Q: What is the connector? i bought this and the jst connector does not fit the jst connectors i have, so what is that connector ???** A: It is JST PH (2mm pitch). There is 12 types of JST connectors listed on Wiki. **Q: Can i cut the connection off so i can solder it to a circuit? if so which do i cut first?** A: Cut one connection at a time, do NOT cut through both at the same time… if you short them together they may weld together and then proceed to burn. If you do cause a fire don’t use water, use sand, dry soil to smother the battery. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by T***H on 12 February 2026* works great and good value ### ⭐⭐⭐⭐⭐ Great replacement battery. *by A***D on 27 January 2026* Great replacement of the battery in an old car hands free Bluetooth speaker found in storage after years which was no longer charging or powering up.
