With a capacity of 1548 Wh, this add-on battery instantly expands your system autonomy, ensuring continuous power throughout the night.
The FlashSpeed Extra Battery 1548Wh features high-quality LiFePO4 (LFP) cells with a certified lifespan of 3,000+ charge cycles, retaining up to 80% of original capacity – equivalent to over 10 years of daily use. The exclusive LIFEBMS™ system provides multilayer protection against overheating, overcharging, and short circuits.
A standout feature of the FlashSpeed Extra Battery is its full AC charge in just 60 minutes. Simply connect the battery to the FlashSpeed 1500 and plug into the mains – maximum capacity in minimum time.
Thanks to the ergonomic and compact profile, FlashSpeed Extra Batteries can be safely stacked on top of power stations and on each other, optimizing space at your astrophotography site, in the boot of your car, or in your home observatory.
No setup required. Just connect the battery to the FlashSpeed 1500 via the included CP3500 cable and the system is immediately operational. The add-on battery discharges first, keeping the main power station always ready.
