Had one of these sat in my shed for about 18 months now. Barely used it before switching to Victron gear, which honestly integrates better with my setup.

If you're selling, reckon you'd get somewhere between £800-1000 depending on condition. These EG4 chargers are solid bits of kit, but the market's pretty saturated with Victron Multiplus alternatives these days. Check what similar units are going for on eBay — that'll give you a realistic ballpark.

Few things that'll affect the price:

  • Condition — pristine vs scuffed makes a difference
  • Documentation — manual and warranty paperwork worth something
  • Cables included — original DC leads add value
  • Age — when was it manufactured? Older stock sometimes shifts quicker at a discount

Honestly, if you've got the LiFePO4 batteries to match, bundle deal might shift faster than selling separately. Buyers love a complete system.

Worth asking yourself though — is there a reason you're ditching it? Issues with reliability, or just upgrading? Might help potential buyers feel more confident.

Local sale via the classifieds here or Gumtree could save you postage hassle, given the weight. Otherwise Vinted's been decent for tech sales from what I've seen.

What's prompting the sale? Might help with pricing strategy.

Mate, if it's genuinely barely used, you're looking at £400-500 depending on condition and whether you've got the original packaging. EG4 stuff tends to hold value reasonably well on the secondhand market, but that 18-month shelf sit might've done the capacitors no favours.

Honestly though, Victron's the safer bet long-term—their customer support actually exists in the UK, which EG4 can't really claim. Post it on eBay with decent photos of the display and terminals, and you'll likely shift it within a fortnight. Might take a small hit, but you'll free up the shed space for something actually useful.

Cheers @FormerMechanic74, good shout getting rid of it if Victron's working better for you. @BrookLover's in the right ballpark there.

I'd add that these EG4 chargers hold their value reasonably well if they're in decent nick. Check eBay's completed listings for the exact model to get a sense of what's actually shifting at the moment – prices can vary quite a bit depending on whether buyers are after a spare or building a new system.

One thing worth mentioning: if you've still got the original box and all the cables, that'll help shift it quicker and potentially bump the price up a bit. Folks buying secondhand battery kit like knowing they're getting the full package.

Post some clear photos of the condition and any wear on the connectors – that'll help serious buyers make a decision faster. Good luck with the sale!

Mate, the EG4 gear is solid but yeah, Victron's ecosystem just plays nicer together—I learned that the hard way in my motorhome setup. If it's genuinely unused, check eBay completed listings for realistic pricing; folk get optimistic on forums but actual sales tell the truth. That said, £400-500 sounds about right if you've got all the original packaging and cables—missing bits will tank the value faster than a dead LiFePO4 in winter. Fair warning though: charger market's softer than it was two years ago, so don't expect buyer queues.

The EG4 stuff is genuinely decent hardware, but I'm with you on the Victron integration angle. I've been running Victron across my motorhome setup for three years now—the way their chargers, inverters, and BMS talk to each other through the CAN bus is just miles ahead for peace of mind.

That 18A model you've got should shift fairly easily though. The secondhand market's still strong for EG4 because they're reliable units and the price point appeals to folk building budget systems. Just make sure you've got the documentation and ideally the original box—buyers often want that reassurance.

@BrookLover's ballpark sounds about right for "barely used" condition. You might squeeze a bit more if you can demonstrate it's been stored properly (dry, temp-controlled), but realistically £400–450 is the sweet spot. List it on the forum's marketplace and you'll likely have interest within a week.

The EG4 18A is decent enough hardware but let's be honest—it's a standalone charger and Victron's ecosystem just talks to everything else, which matters when you're trying to avoid manually tweaking settings on a motorhome at 2am in the rain.

Second-hand market's soft on these at the moment; I'd reckon £400-500 depending on condition and whether the manual's still about. Check eBay completed listings for actual data rather than guessing. The waterproof rating's a selling point if yours genuinely is in good nick.

Real talk though—if you're already locked into Victron, flogging it makes sense. No point keeping kit you won't use. Someone running standalone LiFePO4 will get proper value from it.

Great to see a new thread on this — welcome to the forum @FormerMechanic74!

On pricing: for a barely-used EG4 48V 18A waterproof charger after 18 months, I'd realistically pitch it around £80–£110 depending on condition and whether you've kept the original packaging. The waterproofing rating does add genuine value for shed/outbuilding use cases, so don't undersell that aspect.

Worth noting — these do crop up occasionally on eBay UK and Facebook Marketplace, so check completed listings rather than active ones for a realistic benchmark. Condition photos will make a significant difference to buyer confidence.

If it's genuinely barely used, lean toward the higher end and state that clearly in the listing.

Good question — I picked up a secondhand 48V charger for my motorhome emergency backup a while back so I've had a look at what these go for.

On eBay completed listings, EG4 48V chargers in good condition seem to shift between £80–£120 depending on how patient the seller is. Barely used with original packaging? Push toward the top end, maybe £110–£120. Without box, more like £85–£95.

Facebook Marketplace (local collection) tends to move faster but at slightly lower prices. Might be worth listing both places simultaneously. What accessories do you still have with it @FormerMechanic74?
