Infiray BOLT Series Battery Extender

The Infiray BOLT Series Battery Extender (model AC37) enhances the battery capacity of compatible BOLT thermal devices by allowing the use of a larger 18650 battery in place of the standard 18500 battery. This extender threads directly onto the existing battery compartment, providing over 75% additional battery life for extended operation.

Designed specifically for modular compatibility, the AC37 fits BOLT TL35, TL35V2, TH35C, TH50C, TH50CV2, and TD50L models. It is not compatible with BOLT SE Series models. The extender requires flat-top 18650 batteries and does not support button-top variants.
