LFP is a king for now, all LV inverters use 40-60V range. Price is go down from every year. I buy a 16x280ah LFP Cornex + case with JK-PB2A16S-20P LCD4,3" by 1350usd and I mount it in 4h of work. And I do a 2week testing each cell by tester with save graphs to csv, compare all of them and this is a cheapest way now. All good nad price go down. This is 14,3kWh of storage in 51,2V.
1)Some lfp can handle way higher c rating. Some are geared chemically towards higher c rating. It depends on application and model.. just like with cars 2)the voltage range on sodium is a big issue. Delivering 10.000watt on 52v battery requires a lot less copper than one that runs down to 24v. Its a VERY big issue that you seem to ignore 3) lfp can be used to 0% soc with absolute zero issues. I recommend reading some of will prowders post with scientific research papers by professionals on this. 4) newer models from the last 2 years have hit 10.000cycles to 80% and they continue to improve. I think for most applications, most, not all, 3+ decades is beyond sufficient. By that time we probably have something better.
Thanks for the comment! 1. In this video, the only LFP referred to was the Lifepower4 v1. I will be covering other LFP chemistries in other videos. 2. I wasn't aware of the voltage range issue. If you have some links to more info I would like to learn about it. I do know that some Sodium batteries don't use any copper, and use aluminum in both the cathode and the anode. 3. Are you referring to Will Prowse? I know he has mentioned running LFP from 0-100%. I just used the recommendation from the EG4 manual. 4. I think we will see rapid improvements in sodium chemistries, probably in the next 5-10 years. For now, I'm sticking with LFP which has been working well for me.
@@tarant315 According to the Natron website they can even be shipped fully charged "Natron sodium-ion batteries are not considered hazardous goods and can be shipped fully charged and pre-installed in a battery cabinet."
Excellent presentation.
Thanks!

Nice system!

You can store sodium ion at 0 volt, without damage which would be good news for transportation and storage (insurance costs).
Also sodium don't heat up. I did hear there tests with a sodium and lfp in 1 pack for a car battery. The sodium protecting the lfp from high current

@@tarant315 CATL just launched a hybrid sodium/lithium battery called Freevoy that does exactly what you mentioned. I think it can charge at 4C.
