February 9, 20242 yr Quite decent specs for this battery 1C Charge/Discharge for the 100AH Although 0.66C Charge/discharge for the 150AH 6000 cycles at 80 - 85% D.O.D - remaining 80% Capacity 10 Year Warranty Not sure which battery is in the competition though as there is conflicting info: 1. The competition "Magneto_Email_EnterandWin" document displays the 51.2V 150Ah 7.6KWh battery. 2. The Poweforum 29 January topic "Hey Everyone so to give you an Update on the Giveaway the Awesome People at Magneto Energy has confirmed that they will be giving us a BRAND NEW MAGNETO Lithium-LiFePo4 Wall Mount 48V 7.6KWh Battery for the lucky draw battery review giveaway!!"" 3. However, the review is on the 51.2V 100Ah 5.12KWh Battery. Either way, winning this would be great.
February 9, 20242 yr Eish! Some fellas complaining about having to use an installer. I can do this, and have numerous times, yet I'll use an installer, no problem. For two reasons: 1. I'm grateful that Powerforum runs these kind of competitions. So there's no complaining from me. and 2. maybe I learn something new from a different installer. You never know. Knowledge is valuable. Anyway, just saying. Enjoy the weekend!
February 9, 20242 yr Would love this battery as the previous solar company(Stratton Power Solutions) ran away with my money!!!!! I also had a look at Magneto's Super Capacitor Battery!! What a invention!!! But very pricy.

Same Range of battery same cell tech and BMS just larger Capacity Magneto was going to give away the 5.12KWh rack mount battery but they decided to do us a Favour and give us the 7.6 KWh Wall Mount instead if you follow the link to the battery value its on our online store and 10K More than the 5.12KWh

So what will you learn from your long term review? That it works. Of course it does. It is almost certainly a high quality LTO battery. You would obviously not open it up, but there is a simple test. Charge and discharge it as fast as you can a few cycles in quick succession. (Supercapacitors can charge/discharge almost instantaneously). If it heats up significantly it is not a supercapacitor. (In the test referenced above one charge cycle heated the battery to 44) I will even make you an offer: Cut it open. If it has no chemical batteries in it (only capacitors) I will buy the wreckage from you at full new price. If not, sue the manufacturers for defrauding you, and stop selling it in your store.

Thanks for this post. Due to the marketing bluff around it and the internal battery inside I did not want to burst the bubble. As you said we just have to look at the sirius to know more about the so called tech. As always if the market=automotive have not been keen takers then there is for sure a kink as indicated.

I was very disappointed when I saw that @Powerforum Store was selling this - I can only assume that they have also been taken in by the con-artists. The beauty of this con is that the victim only finds out in 10 years that they have been scammed. A bit like the 20-year warranty house paints... The final straw for me was that @Powerforum Store is now actively promoting these. I suspect that there will be a (well deserved) glowing review, as they do not appear to have the technical knowledge to understand the con. Now at least they cannot say that they have not been warned. Edited February 11, 20242 yr by Calvin

Sorry for posting a reply based on the invention Robin mentioned. We know that the super capacitor batteries we have seen was not a new invention but @Calvin explained why we thought of contributing. If one had to buy it at R53th or R166th it would be a lot of money for what could just be another lithium battery. Admin please delete if out of line or in the wrong section.

For the record the review is being done by an Electrical engineer and the battery will be checked from A to Z Magneto nor Powerforum Store will affect the outcome we pride ourselves in doing honest unbiased reviews of the product. Yes we list the product on our store reasons are consumers have been asking for the product however it is so expensive that one rarely gets sold.
February 12, 20242 yr Fingers crossed I am the lucky winner of this Magneto battery. If I do win it, would be very curious to see if it pairs with my Svolt batteries which also use a Pace BMS - I guess the installer and I would find out, if I win. Results would then be shared with the forum of course!

Yes we list the product on our store reasons are consumers have been asking for the product however it is so expensive that one rarely gets sold. My apologies - I have obviously not expressed my concerns well. I have no doubt that the battery will pass any normal test with flying colours, and I certainly do not believe that the test will somehow be fudged. The problem is with what you can reasonably test. The characteristics that justify the high price (long calendar and high cycle life) can unfortunately not be tested easily. The high charge and discharge rates that capacitors have can also not be tested as these batteries are limited to 2C (30 mins), which is not uncommon for a LTO battery. If the test is as rigorous as the other one we will see that, just like the other one, the temperature will increase significantly when charging or discharging at full current. That will be a tell-tale - capacitors charging/discharging once an hour would show negligible heating. Detailed discharge curves will also reveal the truth: batteries have very different discharge characteristics to capacitors. That could theoretically be masked by having DC-DC voltage converters, but theses batteries clearly do not have them. Read the extensive discussion on @Coulomb and @weber 's AEVA forums (Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale - AEVA Forums) for a very detailed discussion on this topic. Executive summary: there are no capacitors available that can do even 5% of what would be needed to make these devices. I have no axe to grind here - I do not have any commercial interest in any part of the solar industry. I simply hate to see people being scammed out of their hard-earned money.
