Gawd dammit, I just paid $166 for the 12 | 15A the other day! I needed it for the weekend though. Oh well.
I just bought a 100ah lifepo4 battery to use when camping, is this what i need to charge it from the wall? I'm on a budget as well so will the 5A be enough or should I go for the 10A? I was looking at the ATEM one on Amazon but may go for this.
5A will do the job but will take a long time if battery is quite depleted.
Victron makes great chargers, but to be honest for charging your LifePO4 the Atem would do just as good a job.
If you are only going to use it for your 100Ah and around $85 is the most you wanted to spend, I'd probably just go with the Atem for the extra amps.
If you are going to be charging AGMs or your car battery as well and/or can stretch it to the $128 then I'd say get the Victron 10A. The BT and data in the app is pretty handy, and the charger can be used in power supply mode if you ever needed that too.
Probably a dumb question. However are the bigger chargers able to 'step down' as much as the smaller ones?
I guess what I'm really asking is would there be any problem buying the 15A to charge larger 100A batteries and still using it on my smaller 15A motorbike battery? Or would the 5A be a better option for that.
The 15A can be set to 15A or 4A in the app, I use mine for a small motorcycle battery, no issues…
Personally I think it's worth going for a 10 or 15 so you have the ability to recharge a 100Ah battery overnight if you have to… (i.e. if you need to charge it overnight at a paid/powered campground or such)
(My 15 gets pretty hot on the bottom so it's worth being mindful what you sit it on)
You'll probably want a charger with a low current mode for small AGM batteries to be sure you're not going to cook them. The Victron 15A has a low current mode of 4A (10A is 3A, smaller models are 2A). Not sure what your 15Ah recommended charge rate is but I'm guessing somewhere between 2 and 4A?
Thanks, that sounds reasonable. I guess if I don't need the extra features, I'll just go the cheaper route, so long as it gets the job done.
Li-ion doesn't need 101 stages of charging, desulphation etc. 0V charging might be useful though if you drained your battery to the point of the BMS shutting it down.
If you're game to try there are these chargers claiming 20A output for under $70 too (probably less if you looked hard enough).
15 amp would be my choice depending on your usage. If you move around a little and spend every third night in a caravan park and want to charge your dead battery fast you will welcome the extra grunt.
I go with my family for 3-4 days at most at a time, so I'm hoping the 10A will do the trick.
Seems overpriced. I bought a $23 one from Amazon and it works fine on my 12V battery. Charged it from empty to full 3 times now. No issues and just left it charging in my garage overnight each time.
You could say that about almost anything eg “Lexus seems overpriced. I bought a Kia Picanto and driven it to Woolies 3 times now”.
You get what you pay for, I wouldn't risk a cheapy charger on my $500 battery, or take the risk of my campervan going up in smoke…
I'll be the guinea pig then. I'll report back when my car looks like a bonfire

It's worked 3 times? What more could you want!!My batt fails cos I've just joined Kobo and their device drinks batt juice like crazy when car not running. Insurance is void if I unplug. Planning on switching away
The 30A Blue Smart IP22 charger is down to $171.68 from Micktron https://www.ebay.com.au/itm/285120905488?mkcid=16&mkevt=1&mk…
Thanks, got this one. Seems like a no brainer - double the current for $20 more than the 15A one. Seems like its more pro than consumer level of the others.
Just have to make up your own alligator clamp cables or whatever, which isn't a huge imposition for me.
Yeah, my purpose is to replace my battery charger in my van which doesn't support lithium, so I can eventually replace the lead batteries and reduce weight.
If all you are after is a trickle charger then wait for an Aldi charger to be offered for around $30. It’s basically a cheap CTEK.
10 is sold out but other sellers have it at the same price:

Anyone have any recommendations for a DC DC charger? Going to buy a 100 or 200ah lithium set up with the 15amp charger above.
Not Renogy. I have 50A Renogy and it has this weird design decision/fault….
If your house battery takes itself offline (if it has a fault or whatever, which it is totally supposed to do). The Renogy DCDC will suddenly start pulling 1A from your starting battery for no reason. Its like it goes into kind of boot up phase where it just keeps looking for your house battery, all the while draining your starting battery to do all this "work".
As you can imagine, your starting battery will subsequently go completely flat after a couple of weeks of this. Like if you go away and leave your vehicle unattended for a few weeks. Stupid Renogy device has totally killed my starting battery, had to buy a new one as it refused to take/hold a charge after it got Renogy'd.

We have 200 Ahr lithium in our camper trailer. We did a year around Australia so were living out of it. We had the 15A Victron for AC charging when available (caravan parks etc), 25 A Projecta DC/DC and 200W solar. All worked flawlessly and kept us in juice for the trip. 2 fridges draw on average 1 Ahr/hr, so ~50 Ahr/day.
We had the DC/DC mounted in the camper. Even with 3 AWG cable to an from, you were getting ~3V drop to the charger. This means the charger will pull 35A+ to put the 25A into the battery. So watch your cable size - I doubt you could put a larger DC/DC, and certainly not through a regular Anderson.
Basically sounds like the exact set up I'm trying to achieve for our camper. Currently have a 200ah agm that is almost dead so needing to replace it but means I'll need a new dcdc, lithium battery and the AC. Will check out your suggestions. Thanks heaps.
damn. I got the 15A for 180 earlier 3 months ago :(
Not sure about pricing but these chargers are one of the best and the mobile interface and charge stats you get are very informative
