Airtech Studios built the Tanker Battery Extension Unit to relieve the stress on the KWA TK45 PDW's battery and component wiring. This BEU offers additional space for the MOSFET, fuse, and cables all while protecting everything for extended durability. Maximum battery size capacity is approximately 152 mm (5.98 in) x 19.5 mm (0.77 in) x 11.75 mm (0.46 in).

Why choose this BEU?

• Made especially for the KWA TK45 Airsoft Rifle
• Increases capacity for larger batteries
• Separate compartment for MOSFET and cables prevents overbending and damage
• Side crevices provides ventilation for battery to prevent heat buildup
• Locks down TK45's metal rails to steady the buttstock

Why not?

• May add extra bulk to your rifle
• May not be compatible with other AEGs

Pro Tip:
A MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) is an internal component found in some AEGs. The MOSFET prevents battery over-discharge and electrical arcing, which wears out the gun’s trigger contacts. MOSFETs also allow for programmable firing modes, like 3-round burst.
