4x4 Action Group

What do you guys think of this, seems like it's from Oz, but probably made in Shina....

Camponline is an Online store started by 2 of the Conqueror dealerships.
I did post about it previously.


Interstingly this is the 20Amp version at R2950. 00, but....

Takealot has the 25Amp version for R1000 more (R3990. 00).
The 25A one comes with Brad Harrison connectors

Interesting. Building a battery box for the x-Trail and was looking at what Victron has to offer.

This may be a contender (if I can find it in Namibia)

What does the equivalent “main brand “ cost?

Closest one is can find is the 4x4Direct Unit/Lumeno unit at 2.8k

WRND at 2.5k
https://4x4direct.co.za/dc-to-dc-charge ... -mppt.html

National Luna at 9k

And Victron an 5-7k depending on unit + 1000 for a MPPT charger separate.

Well then great price. Whether it will do the job safely and for how long would be pure conjecture.

Thanks Nic, that 1st one from 4x4Direct is a Badger with a big warning not to use the Calcium function as it does not work.

WRND, I hear the guy who made them Passed away, so that scares me off.

Victron doesn't do a combined DC to DC with MPPT, so you have to buy the DC to DC seperately and then buy a Solar controller.

Note that this Atem jobbie does Lithium...

Those Badger/Lumeno units seem right, but I run only calcium batteries (for now) so that doesn’t work.

WRND doesn’t fill me with confidence, at all for the same reasons.

I snagged a MPPT Smart Solar Victron Unit for 950 on Friday, and can get a 30A DC-DC Victron thing for decent price too, will probably end up doing that.

I do like that Victron has an amazing App Ecosystem, so I can always know exactly what my battery is doing, how my solar is doing and how much Ah (roughly) I have left.

But I made Ginger buy one of those ATEM things, and see if he can make it blow up.

4wD Warehouse mailed me to say they have the 40Amp version in stocck for R5000....

However, I did a 2 week trip recently (stand by for a Stunning trip report when I get the time) where I had a fridge in the back of Fearless for the full 2 weeks.
I have no Solenoid, no Isolator, no dual battery, no DC tho DC, no Solar controller.
Fridge never went above 7°C, was always full and I never plugged it into the mains.

But II am a Master Coolerr with an LlLB (Limiting Load to Battery) degree...

I found this Atem power thing on Ali express for double the european price... anyway...
There is a CE mark on this thing but that is the "China Export" mark, the european one has the C and E placed closer together. So this part did not pass european standards for reliability.

As with anything chinese, it will work and then fail in less time than you expect. For short term this will probably be fine. But honestly, you will replace this more often than the next, more expensive brands with good reputations.

Goedkoop koop is duur koop...
