Optimum Ion 12V 120V Battery

Used once then failed – Purchased on ebay July for $666 this suppised 130ah battery was, l admit, sitting for s few months unused while the solar panels snd holding frame were designed, fabricated and were fitted to the car, going thru a ctek charger. The battery worked ok for one day ...then the next morning it was dead and no amount of slar panel or alternator input could bring it back to life. Never again fothis expensivechinese rubbish ..... back to heavy AGM matt which actually work !

Atomic Number3 similar SCAM, avoid at all cost – Similar SCAM as Atomic Number3. RIP OFF merchants putting significantly lower energy battery packs into the box. These are coming from China. Wise up, buy from an Australian manufacturer with a track record.

Not to bad – I purchased one of these batteries about 12 months ago and so far so good I use it mainly for my charging my 4s 6s RC batteries because I get a faster charge from 12 volts as apposed to 240 (go figure). I also use it for my water snake 54 lbs thrust electric boat motor. Now the catch, the only issue that i have is that it doesn’t seem to last long when using it to charge RC batteries, still to determine why,hope this helps

Optimum Ion Lithium Ion batteries sold by SiriusForce is a scam – My (alleged) 120ah lithium battery is no more than 35ah and wont charge above 11.5volts on 240v charger. They are shocking and something needs to be done legally. My battery wouldnt last longer than 3hrs with my Waeco on it. They do not reply to msgs. avoid at all cost.

Under-rated Lithium batteries from eBay/SiriusForce – I purchased a 120Ah "Optimum Ion" Lithium battery from SiriusForce on eBay. I was alarmed that the battery was only 7kg! (A LiFePo battery should be 14-16kg) I am a Solar Engineer and did a charge/discharge test which showed only 35Ah, not 120. The battery sounded like it had a small (5kg?) battery pack sliding around inside. To expedite the refund process, I paid a large Battery Retailer to fully test the battery and give me an official report. The report showed 27% capacity and the conclusion "BAD & REPLACE" I included this report in my eBay 'Refund Case' and attached a copy to the battery. SiriusForce refunded promptly.
