Best mains charger for Lithium

[Lenny HB]

It depends on how you want to use it. If you are rarely on EHU then there's not much advantage over separate charger and inverter. But if you often use a site/aire with EHU then it has many advantages.

From another point of view, I rarely use EHU but I fitted a Multiplus, one of the reasons was if my batteries are low I can hook up on an Aire for a couple of hours for a few Euro and get a good charge into my batteries.

It also made the wiring simpler as I didn't need to fit a mains changeover, also I get a 120 amp charger instead of a 30 amp one.

My plan was to unplug the 240v female kettle lead socket feed to my 119 Electroblok. Swap the 3 pin plug over on the 40a Fogstar lithium battery charger to a male kettle lead plug, then connect those two together. It's a simple swap back over if I ever required it for original 240v charging again. The charger leads +&- would then be run back to the busbars, simple? .

I assume you’ve checked to see if there is a spare 230V connector? I found a spare one hidden away so now have the EBL (with internal charger disabled) connected and the Victron charger connected. If you don’t have a spare 230V connector, I believe you can get a Y connector for a kettle lead - one in, two out - so you could use your existing EBL kettle lead to power the EBL (internal charger disabled) and the Victron charger. That way you don’t have to unplug and re plug stuff whenever you want to use EHU.

Thanks, as far as I know all the 240v does in the electroblok is run the charger when on EHU. I've not seen a secondary socket,but I'll keep you're idea in mind of the dual kettle lead, but I'll give it try without it first and see if it needs amending.

I wouldn't even contemplate putting a 2000W load on a single 100Ah battery. Discharge rate is too high and bms will shut down.
Even if you do get a 100A load out of a 100Ah is not healthy. Max draw 0.5C as in 50A load out of a 100Ah battery.
For a 2000W load, you will need 300Ah battery to supply and sustain that load.

As for the multiplus, I can't recommend it enough, skip the mickeymouse options, and buy once: get a multiplus that will do loads of things, and very robust.
In the event of change of plans, it still has a strong re sale value and little loss if anything.

I agree and think I'll defo get a multiplus. It's just what size to go for. I've just bought the eco worthy 285ah lithium battery so that should power things for a bit.
I was looking at the inverter being able to power truma 6e if I ran out of gas but think it pulls lots of power so I'm thinking the 12/1600 will do for a little 1000w air fryer etc.

I've also not got loads of space to fit all this kit in

I had the 1600 and wasn't quite enough for 1400-1500W load.
I switched to the 2000va model and very happy. The 3000va is almost the same physical size, but, the standby consumption is more. I'm a great believer in limit by design, the 2000va at full chat will never be able to leave me without power or to abuse my batteries.
I would skip the 1600 and go one up.
