Vaping (Unprotected): Using bare, unprotected cells in mechanical mods is extremely dangerous and not recommended.
FAQ
Q1: Does this battery have a protection board (BMS)?
A: No. This is a bare cell pack. You must install an external 3S BMS to protect against overcharge, over-discharge, and short circuits.
Q2: The battery arrived folded. Is it damaged?
A: No, we fold the nickel tabs to save on shipping. You can carefully unfold it to a straight line before soldering. Just be gentle and do not bend the cell terminals.
Q3: Can I use this to rebuild my laptop battery?
A: Yes, this 11.1V 5000mAh 2P3S configuration is standard for many laptops. However, you must verify the physical dimensions of your original battery casing and ensure you have the skills to install the original BMS.
Q4: Can I customize the nickel tab positions?
A: Yes. If you need a specific layout to match your BMS, please contact us with your wiring diagram before ordering.
Q5: What is the actual discharge current?
A: The EVE 25P cells are rated for high-drain applications. However, the actual current depends on the original BMS and wiring you install.
