In an effort to save you money and keep things simple we do not sell the batteries and chargers. These types of batteries are widely available on the internet and from hobby shops. You can pretty much use any battery as long as it can output at least 4aH at 12volts and will fit in the Stroboflash case. We suggest NiMh batteries but NiCd (a little cheaper) or Lithium (expensive!) will work just fine.

 Batteries and chargers- please purchase from links below:

Need Qty. 1  RB-HC10R2T-MT5000 Robot / RC car batteries

Battery Chargers:
Need Qty 1  CHUN-123


12v Battery and Smart Charger Combo:



Alternate Battery sources:

Batteries and chargers are available at most hobby shops. They are used for robots and remote controlled cars. Any 12v NiCd or NiMh battery pack will work (make sure it fits in to your case!). Must be minimum 2500 mAh. 5000mAh or larger is best. 12v lead acid, lawn mower or car battery is great too but probably wont fit in the Stroboflash case.

NEW! Refurbished Stroboflash IV units.

When available.

Complete 200 Watt Second Stroboflash IV unit including Head. $175.00
(RBPS II and Battery not included.)

The best strobe light in Photography!


New 21st Century technology!


The old, heavy, capacitor pack has been replaced with a 21st century printed circuit board and new modern light weight capacitors. Same 200 Watt Second power as the original with half the weight. This is what is inside the refurbished Stroboflash IV. Power selector switch is protected against arcing by large solid state rectifiers. No more burned switch contacts!

Here is what is included in the refurbished Stroboflash IV.

* Refurbished capacitor pack. New power selector switch, printed circuit board, new capacitors. Coil cord is vintage but tested and working. Vintage plastic case may or may not be repainted depending on condition.

* Refurbished Stroboflash head with solid state trigger and new trigger capacitors for 21st century reliability.

Please NOTE:

If you are going to use a Stroboflash with a modern digital camera you must use a Wein Safe-Sync (available from B&H and Adorama) between your camera and the sync cord connected to the Stroboflash head. Most digital cameras can only handle less than 12volts at the PC socket or hot shoe. Stroboflash is MUCH higher than 12volts!

Stroboflash IV refurbished unit only $ 175.00 US

Rechargeable Power supply (RBPS II) and NiMh battery and charger not included.
