  • Relieve a cramped environment for your MOSFET and cables to sit to prevent it from over bending and damage
  • Utilize larger battery capacity
  • Eliminates the unsteady butt-stock by locking down the two metal rails
  • Maximum battery size approx 152mm long x 19.5mm wide x 11.75mm
  • Once installed, the TK45 remains just as compact as before - perfect for CQB use
  • Compatible also with the KWA Ronin 6 PDW Tanker Stock
Tired of using smaller batteries for an all-day game? Here's your solution!

One of the main issues encountered with the KWA TK45 PDW is the limited battery spacing to operate conventional sized LiPo batteries to endure a long-lasting skirmish event.

Once the LiPo was installed into the stock compartment, we found it difficult to fit the MOSFET, fuse and cables back inside without the risk of overbending (which weakens the circuit over time). Likewise, we wanted to minimize the prospect of denting the battery's surface from the cramped spacing.

By offering additional spacing inside the compartment, the Battery Extension Unit (BEU) is designed specifically to relieve all stresses on the TK45's components, while protecting it throughout to extend its durability. There are crevice's on each side of the BEU to maintain a constant flow of ventilation to the battery and components to prevent a buildup of heat.

The BEU is designed to fit beautifully with the TK45s original design by sitting seamlessly inside the stock compartment with no modification needed to install. Made of strong, flexible nylon that is resistant to BB impact and rough handling.

Dimensions: 70mm long x 40mm wide x 50mm

"I can fit an 11.1v titan battery using this on a QRF mod 1
by Justyn P. on 12/10/2021
"I bought this for the QRF mod 2 as i was having issues with the battery being a very tight fit and i wondered if this could even fit on. Fortunately the extension fits into the pdw stock perfectly and gives plenty of extra space. This does prevent the stock from collapsing fully, but i keep it extended out anyways.

Strongly recommend if battery space is needed or the cover needs to be replaced

"i got this for my ronin 6 pdw. although the gun has pretty decent battery space for having a tanker stock i needed more to fit an 11.1v titan power battery. this extension gave me just the right length to fit it. from the picture it looks like it wouldnt match the texture of the stock but it matches and fits perfectly. if it didnt have the airtech logo i would think the gun came with it from the factory
