Special notice:

The product has been upgraded to version 3.0.
The main updates are that V3.0 removes the toggle switch and replaces it with a key switch control, and adds the function of battery charging. All other operating interfaces and procedures remain unchanged.

Notice

1.Please ensure that the environment is open and uncovered, if you can add a fan to dissipate heat, it is better.
2.In order to ensure that the battery clamps firmly, 18650 battery holders use compact battery holders, suitable for flat-head battery measurement!
Does not support charging of LiFePO4 batteries.
3.Note1: Due to product upgrades, you will receive a new and upgraded version. Note2:Applicable to 21700 but requires modifying the battery base, please contact us for details.
