- Batteries, Batteries, Batteries!
When it comes to the topic of Batteries, there is so much to learn and ultimately be aware of, especially if you're a first time buyer!
In this episode, we'll be taking you through some of the pro's and con's around Lithium-Ion batteries specifically, and we'll be giving you a breakdown on what you need to understand about these batteries when you're out shopping for yours!
We learn all about what kWh and Ah stand for and why it's important to take the numbers on that datasheet into consideration when buying a Lithium-Ion battery for your Solar system!
As always thank you for watching, leaving any questions you may have in the comments below, and we will see you in the next one!

Very cool and super insightful! Keep them coming 🔥
Thanks Blaize :)
Thanks for the enlightenment
Awesome.
Yeah, click that On/Off button 🙂
Great vid, legendary.
Please make videos of the more recent products that have been released in the past few months.
Brilliant share - Thanks
I am from PAKISTAN
Please do share a comparison chart indicating Top LFP LiFePO4 Batteries
I have purchased Solis RHI 5kW with Pyontech US3000S
Brilliant! New subscriber...
Thanks
Thanks ..
Questions.Kwh what does it mean in terms of discharge durations?
For example if you had 1kW worth of appliances running, the battery would last 5 hours.
Maybe I’m a bit slow but I didn’t quite understand or get how you determine how many appliances/devices you can run and for how long? Grateful if you could clarify
Here’s our guide that goes into detail on sizing that battery bank solaradvice.co.za/solar-batteries#howto
Good day and thank you for this video. Kindly advise what to do, I have a 5kwh 200ah 24v lithium battery which is new. It charges well but at each attempt at discharge, the BMS trips off after a few minutes (sometimes up to 1 or 2 hours). Please what’s the possible cause for this and what can be done? I was thinking the inverter used is incompatible with it but I wonder if. Besides I want to be sure so that I’ll not change inverter and still face the same issue.
It sounds like the comms between the inverter and battery isn’t right, do you if it is compatible? It can be as simple as replacing the comms cable for the correct one.
nice❤
very informative when i use 25 % of charge then charge its counts full cycle or .25
Yes. It doesn’t matter how much you consume as long as you replace what you have consumed it’s a cycle. Even if it’s 10%.
Just bought a Solar system from Solar Advise, I see on your website the warranty on the battery is 5 years, video says I should ask why not 10 years?
It depends on the battery, but for most of the batteries on the market it's 10 years.
What is typical life time of LFP batteries in terms of cycles ?
The majority of them at the moment are 6000 cycles, from the low end 4000 up to 8000 cycles, there is a brand offering 10000!
Not with load shedding. Many cycles less.
I bought a lithium battery FUSION 4.8 to be specific, i was using GEL BATTERY before . Please help me with the settings of this battery to Axpert inverter in terms of charging and discharging and the communication (using comm cable)
among themselves and if possible the fuse or breaker to use between them (Inverter and battery).
If you have an Axpert then you don’t have the option of comms, you will have to set it in user defined and manually add the amps.
@@solaradvice Thank you, should i use the same settings as those of GEL battery ?
I am asking you this because i was using GEL and after installing Lithium battery my Inverter blew MOsfet transistors (it came with code 09) i was thinking it might be the settings.
Yes you will need to set the Ah to 100 and the DOD to 30A
@@solaradvice Thank you very much..😄
I love lithium batteries they are just costly around here in Africa
💯
100 % DOD should be avoided at all costs in my opinion. I believe that a larger battery pack with CAN communications to your inverters are key. I wish you well.
For what reason would you not want the option of 100% DOD?
@@solaradvice 80% DOD should be a minimum with LIFEPO4 chemistry, I favour 60% DOD on a larger battery pack in series for longevity at 48 volts, it’s just a personal thing. Incidentally do the battery packs you were showing have a PCR Pre Charge Resistor built in too the on and off switch?
@@jeremyallard5449 manufacturers state 100% DOD but this to state that it could reach that limit, I agree that you wouldn’t want to deplete the reserve to that extent, I run mine to 75% although it is 80% DOD
Can we increase the discharge rate from . 5c to 1c ?
Hallo, i ask for 4 room house know how kw baterry i buy
Probably about a 10kWh
question, how do you know or check(if possible even) how many cycles you have or got left?, i mean, nowadays people buy batteries and use them for 5 days and return them cause they do not perform as expected, how do you know they are not selling you a used battery? and before you say, NO they WONT do that, believe me, where i am from, THEY WOULD LOL, a company here selling batteries only give a warrantee on them till cycles are depleted, so if its got 150 cycles, no warrantee even if the battery is 150 days old
Lol, good question, unfortunately you can’t unless it has an LCD screen, if it does then you can access it on there.
Great summary of LFP situation but not enough emphasis on QUALITY, you mention for 5 secs at the end. 99% of these pre assembled batteries are made in China and the cells used to make up the battery is critical. CATL are the biggest cell manufacture in the EV market for good reason, because they are the best full stop. I have clients in the UK that were pleased with EVE batteries three years ago but are already seeing degradation from daily cycling to 100% DOD. Buy batteries that contain certified quality cells and use them between 80 - 20% DOD ie avoid the steep part of the charge/ discharge curve for maximum cycle life. Discharge no less than 20% and recharge no more than 80% you will get >6000 cycles or 12 - 15 years.
lithium-ion?? you mean "lithium iron phosphate"... WAY different!! they are 2 totally different chemistries. Li-ion has different characteristics than LiFePO4.
Correct, we refer to LifePO4 as lithium for simplicity sake, there aren’t many phosphate batteries for sale compared to LifePO4
@@solaradvice yes, sir. just making the clarification as you kept referring to them as "lithium ion" in the video. and the title is also "lithium ion". and what you have in the video, and talk about are not "lithium ion". they are lithium iron phosphate. WAY. DIFFERENT. it's like saying you are going to talk about 'what you need to know about alkaline batteries', then holding up a prismatic cell...
not to beat a dead horse anymore, but sorry, words mean things.
if you had just kept to "lithium" batteries, it wouldn't be a big deal. or a deal at all! "lithium" batteries encompass a few different chemistries. it's that you kept saying "ion" after the lithium that is misleading.
@@dobrzpe yes 100%, it’s something we should have referenced in the video
