November 10, 20214 yr Hi. Hope you all well. New here, so please be gentle I currently have a 24v Synapse 2.4KW inverter, connected to essential supplies for backups only during loadshedding. Currently have it hooked up to 2 x 12v 100ah deep cycle lead acid batteries in series (I know this is old school). These batteries are about 2 months old, and have been working fine) I have been looking at replacing batteries to 1 x Hubble AM4 (24V Lithium) and I have been wondering how this will affect my runtime and if I can add to the essential loads if I change to a Lithium Battery. Except for the additional 40% runtime, and the life expectancy boost of lithium batteries (Life Cycle), will the battery drain still be similar to lead acid? I have also noted that the Hubble AM-4 is rated at 2.6KWh. How is this different from the normal lead acids? Any advice would be greatly appreciated.
November 10, 20214 yr @mrafiq1303, your current batteries total 2.4 kW, you could also look at two S-100 Lithium batteries in series, they are just under R5000 each, they are a replacement drop in for lead acid/AGM batteries.
November 10, 20214 yr Author @Tariq Thanks for the confirmation. I am definitely looking at the S100's but just wanted to check that I am not missing something by not upgrading to the AM4.
November 10, 20214 yr The S100 are build by using second life cells. The AM-4 are using brand new cells. That's why there is substantial price difference between 2 x S100 vs 1 x AM-4. But in any case by changing to lithium, you will have much better DOD. 80%-100% with lithium vs 40%-50% with lead acid. This will give you instant longer running time for the same load.
November 10, 20214 yr Author Thanks for reply. Makes absolute sense. Now to wait 6 weeks for S100s to come back into stock. Cant find them anywhere in stock at the moment.
