FAQ

Can I use button-top 18650 batteries in these holders?

These holders are optimized for standard flat-top 18650 cells. Protected button-top cells can be used, but may require extra care when inserting due to their slightly longer length.

What wire leads come attached to the battery holders?

Each holder includes pre-soldered positive (red) and negative (black) flexible lead wires designed for easy stripping and circuit connection.

Can these holders be wired together in series or parallel?

Yes, you can easily combine the lead wires of multiple holders in series to boost voltage or in parallel to increase current capacity.
