researching to get a battery and this one 200ah says do not use > 800 watt inverter, see link. yet other ads for same battery dont display this limit, have looked at a few other brands which appear to have no limit.
have written to manufacturer...has anyone heard of this sort of limit b4?, has anyone used this battery with > 800 watts.
i will leave money in wallet for a bit longer......

Hi Stoney 123. I'd suggestion getting on of the other batteries. The reason I'm writing this is about the weight of 200ah batteries, not when they are in position but to move them. One needs a winch up their proverbial so to speak. Just a thought. Woody46

Some AGM's put a limit on how many amps you can draw to protect the battery, too many amps could overheat the internals reducing its lifespan, not sure if the same applies to lithium.
Mine are 4 years old & have been hammered at times when we have used our motorhome to supply power to the house in extended blackouts, 3000w PSW inverter on 600 amp hours of battery @ 24v, they get warm to touch.
Could be UPS style battery's your looking at, good for backup but not for constant heavy loads.

Stoney123 hi
Fusion Lithium 200 amp battery
No I have not had any experience with the batteries you asked about.
Weight 28.3 would be manageable only just.
The price of these particular batteries is coming down, good maybe very good.

Plus if it goes you lose all
If you have 2 x 110's as most do you can spread the load and also weight to physically carry around.
With inverters. Specially with a caravan.
Watch the wattage of. unless going the whole hog. electric kettle,microwave,frypan etc.
I use genny for them and air-cond.
I found that a 300w would give 2 lights, small TV and 240v electric house fan
600w watt would give 3/4 lights TV, sat box system and fan.
without draining the battery's too much.
using for the usual 4ish hrs or so of an evening.
Bigger the Inverter. the more juice it uses. Just being there when on standby.
If you going Lithium. Apparently. The best Lithium powder comes from NZ? and US.
So I read.

Sorry all. I didn't take the time to read the details so I'm like Sgt Schultz, I know nothing. One day I was hoping to get lithium type batteries but at the moment maybe I might wait some more. Cheers all. Woody46

Stoney123 these batteries are made up from 4 individual cells packaged in a case and include some sort of battery management system. I suspect the current draw limit may be related to either the management system or the cell interconnects, so I would wait for a reply from the manufacturer to clarify what is intended.
The price seems OK but look at other suppliers as well. One advertises on this forum and another that I have used and is very knowledgeable is Phil at Solar4RVS in melbourne.

Alan, have a look at the link the OP provided. They claim "Unlike many other lithium batteries, Fusion Lithium Batteries are made using prismatic cells."

Peter "prismatic" refers to the shape of the individual cells namely rectangular solid (as opposed to round). They are almost all made in China and then imported as individual cells into this country and made up into battery packs by various suppliers. These battery packs usually include a battery management system to control the charging and discharging limits for the system as well as controlling the individual cell voltages to keep the whole system maintainence free. However individual cells can also be purchased for a DIY setup but knowledge of the charging/discharging requirements and individual cel voltage balancing is required for safe use.

yes, more research shows there appears to be a problem with lifepo4 and inverters, it would pay to ask b4 purchase. (actually get it in writing)
one brand now make the claim " It's also built to withstand the load of a 1000w Inverter, where the other "Big" Brands can only run a 400w Inverter at the most."

i am not spruiking that brand, esp with its price.
Scary stuff if you have just spent 3k on two batteries...........
may just go with multiple agm until lifepo4 matures and price drops. i have still not received a reply from Fusion
