The Age of Lithium Ions Arrives on HPA:
Owners of HPA (High Pressure Air) systems know how delicate the micro-batteries are for powering electronic control units (FCUs). Often, simply forgetting to leave them connected overnight is enough to find them irreparably swollen and ready to be thrown away. TITAN solves the problem at the root with this Li-Ion (Lithium Ion) battery: superior energy density, exceptional charge retention and zero risk of swelling. Buy it once and forget about the problem for years.
Slim "Stick" Format and Native JST Connector:
Designed to power the "brains" of premium HPA systems (such as Polarstar or Wolverine), this TITAN comes out of the box already equipped with the essential red JST connector. No soldering or wobbly adapters. With its 350mAh capacity, it guarantees the energy needed to drive the solenoids for thousands of firing cycles, maintaining lightning-fast trigger response thanks to the 16C discharge. Its elongated cylindrical format (156 x 14.4 mm) makes it perfect for housing in buffer tubes or handguards.
PAY ATTENTION TO THE LENGTH (Where to house it?): Read the measurements carefully! This battery is only 1 and a half centimeters thick, but it is almost 16 centimeters long (156 mm). Don't try to stick it in the motor grip of your M4 HPA, because it will inevitably protrude! Its natural "habitat" is inside the buffer tube, where it will slide without any problems leaving room for the FCU.
The Electronic "Vampire" (FCU): It's true, TITAN Li-Ions are practically immortal and don't swell like LiPos. However, HPA control units constantly consume a small amount of current even at rest. If you leave the battery attached for weeks, the FCU will completely discharge it. Always take the trouble to disconnect the JST connector at the end of the game to guarantee it a very long life!
