In this video, I delve into the lead acid vs lithium batteries debate, specifically focusing on LiFePO4 vs lead acid comparisons. As we progress through the video, I'll weigh in on the lifepo4 vs lead-acid battle by breaking down their characteristics side by side. From their life cycle to depth of discharge and efficiency, we examine each aspect to see how lead battery vs lithium ion stack up against each other.
Starting with traditional lead-acid batteries, I assess their robustness, life expectancy, and the financial implications of their lower upfront costs. Understanding these aspects is essential for anyone considering the established path in off-grid solar power systems.
Transitioning to the innovative LiFePO4 batteries, I spotlight their remarkable longevity, minimal weight, higher efficiency, and their superior depth of discharge. LiFePO4's safety parameters, temperature resilience, and charging rates (C-rate) to give you a clear perspective on their rising popularity in modern off-grid systems.
The video end with an in-depth cost analysis, comparing the long-term value of LiFePO4 against the initial affordability of lead-acid. This vital comparison is designed to resolve the lead-acid vs lithium debate, aiding you in making an informed decision tailored to your solar power needs. Watch as I break down how these two types of batteries will interact with your system's fuses and overall efficiency, ensuring you select the right battery for your energy needs.

My first battery bank of 12 volt flooded lead acid marine batteries lasted me right at 5 years in an off-grid system that was almost always fully charged up and run down to about 12.1v on a daily basis, sometimes a little lower, 11.8v was the lowest I ever saw I think. Doing the math that comes to around 1850 Cycles. Going to 6 volt sealed lead acid batteries and not going under 12.4 volts, usually 12.6, will possibly get me about 3,650 Cycles I think, which is a much more favorable comparison to the lithium batteries. I think I would need two of those 100 amp hour lithium batteries to do what I'm having my 6 volt batteries do and that would be a $600 Vs 439 comparison. Will be interesting to see how long these Mighty Max batteries last. I've got two years on my oldest set. I think around 1 year on another set, and maybe 6 months on a 3rd. I'd like to see how long these latest lithium batteries actually last and if there's any catastrophic failures. I'm old, I don't trust new technology. 😅

Lead acid is simpler than lithium indeed. If you don't have the need to replace the batteries then sticking with lead acid can be ok too. Otherwise there needs to be some changes to the system. But long term, lithium will always win.

You should do a comparison of industrial flooded lead acid compared to Lifepo4. Over 2000 cycles at 100% depth of discharge, over 4500 cycles at 50%. Much better for off grid applications

One might reconsider the last cost comparison and instead divide efficiency cost by the expected life cycles which shows LiFePO4 batteries cost 9 cents (USD) per cycle where AGM Lead-Acid batteries cost 45 (USD) cents per cycle... cost/cycles=cost per cycle

Great addition, thanks! Formulas: lead-acid $488/1000=$0.48 and LiFePO4 $466/5000=$0.9

Im starting to lean towards lithium as days go by. My clients hardly know how to maintain lead acid batteries. But they know how to use a smart phone and its easy to connect to the bms.

Lithium batteries don't need maintenance as long as there are no BMS problems ;)

For deep cycle use running my 1500w inverter, the higher current draw over a longer period of time, the lithium battery wins over lead acid. The lead acid battery you can get a voltage drop with higher currents and the inverter then shuts down. I was amazed how good lithium performs for deep cycle use compared to lead acid. For smaller loads the lead acid can be fine though.

And they are almost the same price!

Lifepo4 can't even compared with lead acid, i got 4 new lead acid in my solar system and after i put Lifepo4 i been much more happier and working very nice the system, not even close to lead acid.

I have been using 12 6volt lead acid batteries til 2 of then died and I am currently still using 8 of them. I am looking to replace them with lifepo4 batteries and I think I am able to use just 4 lifepo4 batteries to do the same work .

Yes, 12V 100Ah lead acid is the same as 12V 50Ah lithium, but with more advantages. Check my video 'Replace Lead Acid Battery With Lithium' for a guide on how to exchange them.

No, you are mistaken. You are talking about Li-ion batteries which are found in phones and electric bikes/kick scooters. LiFePO4 swells when overcharged and does not produce a flame when punctured.

@@kevinward7498 Because lithium-ion is more suited for fast charging and discharging amongst others. Every battery type has it's designed purpose.
