The T-Model 3 R-SPEC 5000mAh Battery is the top tier battery and a great upgrade for any 21700 flashlight. It's always great to have a backup ready too.

 - Flashlight not included - 

Here are GENUINE Model 3 cells saved from never cycled, assembly modules, usually caused by a bolt pattern, busbar, or BMS defect. The cells are professionally cleaned, tested, wrapped, and most importantly the positive cap is added which allows you to spot weld these cells just like any other cell. The Model 3 21700 cell is the most sought after cell on the market and we have them at amazing prices. Yes, these have the signature "3 lines" on the negative side.


Model 3 21700 cells are 5000mah capacity when new and these test consistently slightly above that rating which is why some are labelled 5000mah and others are labelled 5000mah. They are all the same cells. Since these are EV cells they are perfect for any application like flashlights, DIY powerwalls, EV conversions, mobile solar generators, etc.
