High-drain power for your 24V/25.2V power tool battery rebuilds.
This EVE 25P 7S 18650 Battery Pack is a pre-assembled bare cell configuration, featuring seven genuine EVE 18650-25P high-drain cells arranged side-by-side in series (7S1P) with spot-welded nickel tabs. It delivers a nominal 24V/25.2V voltage (29.4V full charge) and a 2500mAh capacity, with a powerful 12C continuous discharge capability.
The inline layout makes this pack suitable for rebuilding 24V/25.2V power tool batteries. Please note: This pack has NO GAPS between the cells. It is NOT compatible with power tool housings that require plastic cell holders/spacers.
IMPORTANT: This is a BARE CELL PACK.
-
No BMS (Protection Board) is included.
-
No wires or connectors are attached.
-
The nickel tabs are pre-welded at specific positions: Total Positive B+ and Total Negative B-. Please verify your wiring carefully.
-
You must have the skills to solder your own connections and install an external 7S BMS before use. Never use or charge this pack without proper protection.

Applications
Recommended For:
24V/25.2V Power Tool Rebuilds: Ideal for replacing dead cells in compatible tool batteries (requires 7S BMS and no plastic spacers).
DIY Battery Packs: For building custom 24V power packs for robotics, portable devices, and LED lighting.
Custom High-Drain Projects: Spot welders, portable jump starters, or any project demanding high burst currents.
Not Recommended For:
Power Tool Housings with Plastic Spacers: This pack has no gaps between cells. It will not fit into housings that require cell holders.
Beginners or Plug-and-Play Users: If you cannot spot-weld, solder, and install a BMS, do not buy this product.
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 7S BMS to protect against overcharge, over-discharge, and short circuits.
Q2: Will this fit my power tool battery?
A: It depends on your tool's internal design. This pack has no gaps between the cells. If your original battery uses plastic cell holders/spacers to separate the cells, this pack will be too wide and will not fit.
Q3: Does it come with wires?
A: No. It only includes spot-welded nickel tabs. You will need to solder your own wires.
Q4: Can I customize the nickel tab positions?
A: Yes. The image notes that tab positions may vary. We can weld the tabs according to your specific wiring diagram. Please contact us with your layout requirements before ordering.
Q5: What are the dimensions?
A: The seven cells are arranged inline, measuring approximately 128.8mm (Length) x 65mm (Height) x 18.4mm (Depth).
