⚠️ Attention:
Some older FLi-OVERLANDER units were built with non-replaceable battery packs and do not include the two-prong JST connector used in the current design.

Because there’s no easy way to know which version you have until the light is opened, we include a two-prong JST connector with every replacement battery.

If your light already has a JST connector, you can simply plug the new battery pack in.
If it does not, you’ll need to solder the provided connector into place to complete the upgrade.

Note: Installing the connector requires soldering and basic electrical knowledge. If you’re not comfortable with this process, we recommend consulting a technician or experienced hobbyist.
