EZA 130 lithium power pack - anybody using one?

Power stations may be cheaper than a lithium battery as they are complete with solar mppt controller, inverta, mains battery charger ,cables

I’m very vaguely toying with the idea of replacing my AGM leisure batteries with lithium but am put off by the complexity despite the wealth of information on this website, mainly from Phil. As a result I am somewhat attracted by the very expensive EZA 130 system. Is this so much better than the standard but complex lithium install?

Looking at the specifications it’s a box with a battery with similar connectors that other makes offer but seems more expensive. I think that if it works for you then go for it. Some folks don’t need such a setup. I am thinking of a bluetti due to popularity and cost and portability. My existing wet batteries are fairly new and are well able to produce the power I need. The next step is LifePO4 batteries a DC2DC converter and a lithium mains charger upgrade. The lithium batteries last 10 years and can provide 80% of power. Whereas wet batteries last 4 years and offer 50% power draw. So lithium is the way to go but it depends on your needs. It’s better to install an inverter with lithium batteries and associated hardware than a powerbank due to extra batteries you can install but a powerbank offers flexibility that’s the main point I am reading

I think that's why these EZA units never really caught on, and have long been out of production now, just far too expensive for what they offered. As far as I can make out from the paperwork passed on with the van, it was installed when the van was a couple of years old in 2017 by Roadpro together with a Kisae 2KW pure sine wave inverter at a total cost of over £4k! Somebody had more money than sense.

It actually works really well, but at only 130ah, isn't really big enough for the way we use the van. I have replaced it with a Fogstar Drift 300aH, Victron Orion XS, BMV712 and 100/30 MPPT. The Kisae inverter will stay for now as it works perfectly well, but I'm itching to get a big blue box to replace that as well

Will also be adding more solar on the roof in due course.

We rarely use hook up, but have bought a Victron IP22 charger to replace the original factory fit CBE charger (no lithium setting) - just have to frig the 'net sense' connection that tells the CBE panel to trickle charge the vehicle battery when on hookup, and that will be achieved by using a very small 100mA LED driver to provide the 12v signal.

All completely unnecessary really, but for me, half the fun of owning a camper van

Picking up on a very old thread, but I have just removed one of these EZA130 power packs from my new (to me) IH630 and replaced with Fogstar/Victron, primarily due to my obsession with the brands, and just because I could

The EZA is actually an awesome bit of kit, with built in 50A B2B and 30A MPPT, with an internal shunt/external monitor very similar to a Victron BMV 702 (non Bluetooth)

It is in full working order, so wondered if anyone wanted to make me an offer, maybe £200? A significant saving over the outrageous original £3K purchase price

It weighs about 25KG, so would need to be collected from near Droitwich in Worcestershire.

PM me if interested and I'll send further details.

The battery has now been promised. Hopefully will provide it's new owner with hours of fun

What is a little different - and I won't put it as either a positive or a negative - for the EZA compared to other similar units of its time is that it includes a Battery in the box.
As an example, I supplied on request a time back a Redarc Battery Manager, which includes a DC-DC (B2B) Charger, an AC-DC (Mains) Charger, an MPPT Charger and a Shunt plus control panel. Given the cost of a Lithium Battery back when this EZA was introduced, the cost difference of the Redarc Manager 30 plus a comparable Lithium Battery is not that much less than the EZA130.
And going back to that time, the cost of Victron kit was way higher than it is right now.

I don't think it is really possible to look at the cost of this kit and say "what! that is way too much money" without considering how much stuff cost back then. Take the Relion RB100 100Ah Lithium Battery mentioned back in 2020 ... he said you could get a pair for under £1000? a couple of years earlier and those were £1,000 EACH. Right now people are buying 560AH Batteries for under £1,000.

I would describe the EZA probably as a forerunner of the more advanced integrated Power Stations, but not as capable in some ways and a bit better in others.
I don't know if they are made anymore? I doubt it very much as superceeded for sure, but has its pros still.
