12V NiMH Battery Pack 2800mAh (10x AA) – Compact 2x5 X-Type Block Layout with Large Tamiya Plug for RC Toys & DIY

High-capacity 12V power packed into a compact, space-saving block.

This 12V NiMH (Nickel-Metal Hydride) Battery Pack is constructed with ten high-capacity AA cells, delivering a robust 2800mAh capacity for extended runtime. Engineered in a compact 2x5 X-Type (Double-Layer) layout, it forms a blocky shape measuring approximately 70mm (L) x 49mm (W) x 29mm (H). Pre-wired with a standard Large Tamiya 2P Plug, it serves as a direct, drop-in replacement for your old or dead battery packs. NiMH chemistry is known for being eco-friendly, free from memory effect, and capable of providing stable power through hundreds of recharge cycles.

 Important Sizing Note: The physical dimensions of this X-type block pack are approx. 70x49x29mm. Because it is stacked in two layers, it is thicker (29mm) than standard single-row packs. Please carefully measure your device's battery compartment to ensure proper fitment before ordering. (Red wire = Positive +, Black wire = Negative -).
