High-Capacity Battery for B1 and B1X

The Profoto MKII lithium-ion battery powers Profoto B1 and B1X monolights, delivering up to 325 full-power flashes on a single charge. It is designed for photographers who need reliable, portable power for extended location sessions with compatible off-camera flash units.

Verify Monolight Model and Charger Access

Confirm that your flash unit is a Profoto B1 or B1X 500 AirTTL model before ordering. Check whether you have the 4.5 A quick charger for the 1.5-hour recharge or the 2.8 A multi-voltage charger which requires 2.5 hours, as charging speed depends on the charger used.

Integrates Directly with Compatible Monolights

The battery slides into the B1 or B1X body, adding only 1.2 lbs and measuring 3.3 by 4.1 by 2.6 inches, so it fits existing kits without extra mounting gear. Built-in fuel-gauge LEDs on the battery and chargers show real-time charge status, letting you monitor power at a glance during shoots.

Questions about this item

Does the Profoto MKII battery ship with a charger, or do I need to buy the 2.8 A multi-voltage or 4.5 A quick charger separately?

The battery itself is sold alone; both the 2.8 A multi-voltage charger (2.5-hour charge) and the 4.5 A quick charger (1.5-hour charge) are separate accessories you must purchase.

I see two charger options — 2.8 A and 4.5 A — which one should I choose for the Profoto B1/B1X battery?

Choose the 4.5 A quick charger if you need the fastest turnaround (1.5 hours); the 2.8 A multi-voltage charger takes 2.5 hours but may suit travel where only standard voltage is available.

What does the 325 full-power flashes rating mean when I use the battery with a Profoto B1X 500 AirTTL monolight?

At the B1X's maximum 500 Ws output you can expect roughly 325 pops per charge; at lower power settings the count rises into the thousands.
