Hi all,

I am going to get an Elinchrom Ranger RX Speed AS generator
I know I am going ot have to change the battery and that is not a problem

I have a problem as the seller does not have the charger

For me it should not be a problem as I already have a freestyle but I want to have another charger

I have seen that charger are insanely high priced
I is just a lead battery to charge to I was thinking of building my own

does anyone have the reference of the connector and a schema for soldering?

Thanks in advance

Fabrice

I believe it's just a SLA (lead) battery and you should be able to use any charger aimed at the automotive market designed to charge 6V, 12V, etc. batteries. The challenging part might be rigging up the interface so you don't have to pull the battery from the housing to recharge it. If the charge port on the housing simply runs directly to the battery and not through other electronics, you can probably just add the appropriate plug on the cable of the charger you buy. If the charge port does run through additional circuitry, you could perhaps add your own port to the housing to plug in the aftermarket charger and bypass the original charge port.

FWIW, you could also look into replacing the SLA with a lithium battery instead. I did this with my four Quadra packs. I replaced all the SLAs with LiFePO4 batteries in identically sized battery housings and ran the charge port and cable out the side of the battery box. The Quadra battery box for the SLA battery is just a direct cable connection to the charge port and the terminals that mesh with the generator/pack without any intermediate circuitry. With this conversion I can do day-long shoots with multi-hundred shots at the fastest recycling speed and not need to charge the battery. With the original SLAs I'd maybe get 100-150 shots at most and the recycling rate would drop relatively quickly.

I found this worked fine with the old Quadra packs but the newer ELB400 did not like the converted batteries when doing rapid series of flashes. It's probably more sensitive to voltage/current fluctuations than the older packs. And indeed, from a teardown I saw of an ELB 400 battery, it has a complex looking circuit board between the battery and the terminals that connect to the generator.

But the Ranger RX is at least as old or older than the Quadra and might similarly tolerate such a 'hack' lithium conversion.

When I bought the lithium batteries, the supplier had two types. One type was for continuous power drain applications and the other was optimized for deep surges, such as starting a vehicle. I bought the continuous drain style because it was available in the identical size housing as the SLA battery used by Elinchrom. But the other type probably would work better for use with strobes because it's designed to better handle the sudden surges each time the strobe is fired, particularly at or near full power. Unfortunately the smallest battery of this style was too large to fix the Quadra battery box. But with the Ranger system, the battery box is much larger and it should be possible to use this option instead.

Also worth mentioning is that the lithium battery will be much lighter. And you should be able to get a much higher capacity battery the same size as the original one for the Ranger.

Does anyone have any current Ranger Rx compatible lithium battery recommendations? I see a lot of possible options on Amazon.

Also does anyone know what kind of connector the original charger uses? I would like to use a smart charger like this but at a lower price: https://www.ebay.com/itm/225799998732

Edit: Pretty sure it uses a 5 pin DIN connector: https://www.amazon.com/Plastic-Female-Adapter-Interface-Connector/dp/B09N1J8Z8N/

Thanks

Below is where I bought LiFePO4 batteries for my Quadra conversions. Due to the Quadra's small battery box, I went with the same form factor, same voltage (of course), but higher capacity than the original SLA. I'd think it would be the same with the Ranger - same voltage and whatever capacity you can afford or can fit.

The battery I bought was their PVC-wrapped style with two leads coming out the side. One for charger, one to connect to the battery box. The charge lead I passed through a hole I drilled in the battery box and taped it to the side. Not super elegant, but it bypassed the original charging port and avoided the need to find/figure out the correct plug to then adapt to the smart charger.
