Bowens Pioneer S1 2.5Ah Battery with Shoulder Strap for the Pioneer DC Powered Flash System

At the heart of any portable flash system is a dependable battery and the Pioneer offers a choice of two. Both are sealed lead-acid batteries, noted for robust and trouble-free performance and none of the memory limitations that plague alternative types.

For added convenience, and no surprises while shooting your job, Pioneer batteries feature a charge level indicator that shows the state of charge at all times. They are also voltage-stabilised to +/- 1% with overcharge protection.
