Hi all, Happy New Year to you all.

 

As the title suggests, what's the collective thought of these batteries from Ultramax? I have asked them if they are a direct replacement to the SLA type and they say they are indeed. Are they worth it, will they hold the system tight for much longer with mains failure than an 8 hour stint from SLA? As li-ion is the most unstable battery known to man, would you need to monitor its environment with regards to temperature triggering a zone maybe?

 

Look forward to your thoughts

What does your panel manufacturer recommend?

Its lighter & claims 6 x the service life of a lead acid battey

 

but its still only 7Ah & 6x the price of lead acid one ?

 

I'd rather buy 6 lead ones as 18-30yr service life it likely me or the equipment it powers will be dead ?

Good point, as Menvier brought out the M2000 they did specify a sla, but in fairness that was recommended over 13 years ago - tech advances have moved on.

Yes 

 

I would recommend upgrading panel and battery when you do it .....

Nah, I think I shall stick with the SLA, as its a lot safer or should I say less prone to getting warm and spewing sparks and smoke out. I have progressed from a TS700 years and years ago to my now M2000 which I really like - just wish it had more custom outputs because 8 just isn't enough for me. Do you still play with these al-yeti?

Yes , I bin them often as I can and use modern equipment that has what I need and customers need 

Fair enough, I may change one day when and if it packs in.
