Hello,

I don't know that much about electricity and electronics, I'm in this learning process trying to get this camera to work (just like maybe you are).

After searching the posts in this forum I have learned some things about the battery requierments
for the Konvas 1M camera's motor.

-That the original battery was a 8.5V 15aH battery.

-That a 12V SLA battery will be too much for the transistors and cause them to burn out.

-That a 6V SLA battery is ok for 8fps and 16fps but not good enough for 24fps and 32fps.

-That it is possible to modify the motor so that it can use 12V batteries.

So the most immediate thing I can do is get a battery and power this baby up, so
I've looked on the internet for 6V SLA(Sealed Lead Acid) batteries.

I've found quite a few 6V SLA batteries on the internet with a varying degree of aH.

Ok so, knowing that the original design used a 15aH with a 12V battery, what is the maximum aH I could use with a 6V battery?

Also 15aH?

If so I found this battery

6V 14aH SLA Rechargeable

What do you think?

or what do you think about this 12v DC to 8.5V DC Converter, would this work?

If you connected a 12V SLA to this and then connected this to the 15EPSS motor would it be good? :

This is bad device for 15EPSS motor.
At first - Peack current 11 A. The user manual of 15EPSS told about peack current 23A, nomimal 9A.
From other side, the circuit of 15EPSS power unit ask of battery, because to sum up of voltage of voltage changer with voltage of battery.
The AC-DC, DC-DC power supple can be unfit.

The original silver-zinc cell SCS-15 rare and will have very high price ( price of silver ).
The power unit can be upgrade for 6 v battery and will carry of all speeds with 6 v battery.
The 6 v 4ah and more high power battery carry of 24 fps with serviced camera.
( from my practical experience ).
I work with 6v 4 ah SLA batteries.
6v 10ah can be good, 15 ah battery can be better, but, need check of dimension and can you set of battery inside of power unit.
The wires from battery to power unit must have minimum length.


P.S You can ask me about upgrade of 15 EPSS power unit for 6 v battery.
