Space Vector Batteries

Powering our National Defense.

Space Vector currently fabricates a variety of rechargeable (secondary) batteries used in launch vehicle, spacecraft and Unmanned Aerial Vehicle (UAV) applications. These rugged 28 Vdc batteries power vehicle systems under severe boost and space conditions. Batteries can be mounted with or without isolators. The 2.5 AH battery is used on several range approved RCC-319 Flight Termination Systems (FTS) and often coupled with our FTS relay box to power the command/destruct receivers, S&A, and destruct ordnance as shown the block diagram below.  Our batteries have successfully passed qualification level thermal cycling, vibration, shock, vacuum, humidity, fungus resistance, fine sand, salt fog, explosive atmosphere, and EMI/EMC testing and have flown on a variety of missions and vehicle configurations.

Space Vector produces a line of aerospace grade lithium-ion and lithium-polymer batteries. The 2.5 Ah Li-Ion FTS battery is designed as a drop in replacement for our existing 2.2 Ah Ni-Cd battery and incorporates high-current cells capable of delivering over 30 Amps (30 ms pulse) at 28 Vdc under extreme environments. The 20 Ah Lithium-Polymer (Li-Po) system battery is capable of delivery over 200 Amps continuously from a single, lightweight package. Each battery uses SVChargeTM Smart Battery Technology which provides Programmable Protection and Monitoring. The cells within the battery are balanced during charging with optional “Flight Mode” lockout of protection features during flight. Li-Ion and Li-Po batteries can be purchased either with an internal or external Battery Management System (BMS). Battery Chargers are available to discharge the batteries in the field, measure capacity, and display cell voltage, current, and temperature.
