Looked at some of the astronomical prices for a profoto Bat Pac   about $1900.  Some photogenic battery  packs about$300-400 bucks. seem more doable.

Recently read here some cheap Charlie decided to build his own,  a diehard car battery and an inverter.. yeah read the admonitions for a pure sine wave inverter   I have Honda EU 2000 I   which works fine..  except this time the gonzos 86'd my genie  and I had to rely on speed lites and a B1.... My profoto D1's suck power pretty good.. any suggestions on a DIY battery setup... I'm gonna put it on wheels... BTW profoto's specs say nothing about input  voltage requirements   110-  60Hz

First suggestion: Don't use a car battery. They are designed to maximize cranking amps and not for deep discharge.

What you want is a deep cycle battery, preferably an AGM so you don't have to worry about spilling electrolyte. Deep cycle batteries are built using thicker lead plates which aren't porous.

see http://batteryuniversity.com/learn/arti … _batteries

Second suggestion: Get a decent charger or an inverter/charger. The cheaper chargers you see at an auto parts store will damage an AGM battery.

I've used this charger for years, it does it all.

the D 1is a bit more than a thousand... Yes  not enough juice.

I did mention a DIY solution ?   I have a Honda EU 2000i...   sometimes the just don't allow you to take it along...
I have profoto d1's  and want to power them guys up... 500ws each   imnput  110-120V 60 Hz   aside from that   not much  more   everybody says get a pure sine wave inverter,,,, any recommendations??

The Profoto BATPAC is about 1900   bucks... guaranteed to work... wanna save a few  bucks

I understand wanting to save $$$
The BATPAC price tag is pretty insane
Just giving you some other options that I believe in one case is tested to work with your units
Also fairly cheap (PB unit $240)

$442 after rebate - This runs 2 D1's at full power for about 100 frames, or 1 for around 225 frames per battery, it comes with 2.

Looks like a nice setup only 3lbs
With 2nd battery a good deal as well

The Photogenic ION Lithium-ion Pure Sine Wave Inverter looks to be a copy of Paul Buff's Vagabond Mini.   The Vagabond Mini with an extra battery is about $330.

If the Photogenic ION Lithium-ion Pure Sine Wave Inverter will power your lights, then so will the Vagabond Mini.

Neither can match the sustained power output of the Profoto BatPac.  The BacPac is rated at 600W continuous output.  The Photogenic ION and Buff's Mini are only rated at 120W.  If you can live with slower recycle times (and your lights are compatible), the ION will save you a lot of money, and the Vagabond Mini will save you even more.


When it comes to portable power, you need to look at the peak demand of the lights, and how much less they will settle for.   A typical monolight can peak at 1,800W while recharging.  You are not going to get this from an affordable battery/inverter system.   The questions are how does the power source deal with the overload, and what happens to the light?

The Photogenic ION and Buff's Mini are current limited sources.  Under high load they maintain pure sine wave output, but voltage drops (perhaps as low as 65VAC).  Buff's and other compatible lights work with this lower voltage, but recharge more slowly.


Before buying a battery inverter system for your lights, I would find someone who has the desired combination of power source/lights and make sure they are compatible.

I'd research Jinbei discovery series... An LED modeling lamp makes it practical to use with Jinbei's lithium ion battery.  Price is good too.
