Standalone Mods

Start with the power source

The LETO 2.1 Brushed uses an 18650 IMR battery. Its product page gives a minimum continuous discharge current, to be completed by the calculation matching your coil. A high capacity in mAh does not replace this current check.

Check the complete build

Check the condition of the insulators, the contacts and the switch lock. Measure the atomizer's resistance before installing it and make sure the value stays stable after assembly. The mechanical mod guide describes the order of these checks.

Finish comes after operation and size criteria. To keep your gear in good shape, look up the mod parts and the maintenance instructions. A part that looks similar or a thread that starts to catch is not enough to confirm compatibility.
