If they under warranty they from brick and mortor store they sometimes replace them. Have good success with battery centre before
Out of warranty, they did actuallly last quite well but this year has fckd them totally. Were 2 x Mecer 105ah am thinking of finding someone who does reconditioning which might just get them to last a little bit longer.

Re-conditioning may give you a few more months, may. Would be cheaper to just go LFP now, longer cycles with better DOD.

You should be able to get some more life out of them.

Make sure the Person is using a Victron charger. I have seen some batteries last 4-6 more before they are dead dead
 
Can you put a LiPO battery on a regular inverter?

Or must the inverter+battery match?
You can. But if the inverter has no settings (like the IVR2400) just monitor the voltage of the battery. Otherwise the inverter will drop the voltage of the battery to below its bms cutoff and you will have a whole other issue of trying to wake up the BMS

Shouldn't the internal battery BMS on the 'drop in' LFP's like Hubble's S-120 prevent this?

The issue is when the BMS cuts off for voltage low, the inverter now sees no battery and won't switch on. You have to either connect a 12V LA like jump starting a car or connect an external 12V charger to "wake it up".

So they aren't exactly the 'drop in' replacements they are made out to be...

The chances of you taking it that low are very low. Some LFP's have a lower cut off than hubble so the inverter should cut off first and you won't have this issue. I have yet to hear anyone on the forums have this issue yet as the battery just lasts and lasts waaay longer than their old LA. Remember, LA under high load loses capacity, and you might only get 60% capacity vs LFP which doesn't have this problem. For example: LA 100Ah (C10) will give you 100Ah over ten hours (1200Wh@120W), now if you put a 500W load on it, this will drop to about 60Ah (720Wh@500W), nevermind the whole 50% rule.

100Ah LFP will give you (12.8Vx100Ah=1280Wh), regardless if you use a light load or a heavy load so even though they are the same capacity on the label, there is more Wh in a LFP.
