You can use this: https://www.thecustomsabershop.com/3...ger-P1180.aspx

Just make sure you get the appropriate connector for however you plan to charge it.

Ok, looking at that picture, I’m not really sure I see how it works. Where/how do I plug the battery in? Do I use the jst connecter on the battery?

You can, if you get the matching adapter. You can also recharge it using a recharge port, again, as long as you have the right adapter.

Here's the adapter to use with the charger https://www.thecustomsabershop.com/T...pter-P701.aspx
