GeorgeD1: At this time, lithium battery will still be at about 53V at least. One thing people don't fully appreciate in lithium chemistry is the improved charging efficiency. Lithium charging efficiency can be as high as 95% or more compared to about 80/85% for lead acid. So, you waste less solar power to charge your lithium batteries and on poor solar days you fill your battery more quickly. Lithium is just superior to lead acid in every way, people saying otherwise are just being purely dishonest or poorly informed. 11 Likes |

GeorgeD1: You and this your TriStar, still pumping amps. Nice one. |

adrusa: I think you have not been really reading through the thread, you pick what you like. No one is disputing lithium capacity. If someone ask a question, na crime to ask if it is not lithium , or answer the question on lead acid . Let me ask my brother do you have 5 years on lithium use. 2 Likes |
adrusa: 10:55am On Aug 02, 2022 |
samnaija: Actually, this question of 5 years is a fake question. You are asking knowing fully well that Lithium for solar became practicable/affordable only about 3 or so years ago, especially in Nigeria. However, if you are asking for experience with lithium batteries in general, then the answer is yes, even you are likely to have used lithium battery for more than 5 years. 4 Likes |

Thank you everyone for your responses to the Lead Acid and Lithium debate Key takeaways: 1. Lead acid takes more space, Lithium takes less space 2. Lead acid is heavier, Lithium is lighter 3. Lead acid has a lower DOD, Lithium has a higher DOD 4. Lead acid can give fewer cycles, Lithium can give more cycles 5. Lead acid is cheaper, Lithium is more expensive 6. Lead acid has relatively been cheaper all along, Lithium has only recently become more generally affordable 7. Lead acid has less capacity, Lithium has more capacity 8. Lead acid has inferior charging efficiency, Lithium has superior charging efficiency 9. Lead acid is cheaper, Lithium is a tad more expensive That said, I think that my first Lead acid installation will last a very long time, it has not been fully discharged since been set up. Infact, I turned it off each time that I got the low battery warning and that has happened less than 10 times. Each time that would happen, I recharged them using the generator. I intend to add solar s so I can do the charging without mains or generators. With what I know about DOD, I will never allow the batteries to go beyond that. But now having compared and contrasted the options open to me, I decided that it is better to upsize the installation to fridge, freezer and AC than try to purchase Direct Current fridge and freezers. I also want several days of autonomy. I also want all heavy loads of the mains, I intend to use mains only for lighting and my backup power source, and that is how all those questions came about. Your input (by your, I mean everyone who spoke for and against Lead acid batteries) has been invaluable and I attempt to take this route. Thanks. 3 Likes |

dammodee911: Deye was recommended to me, and this same problem occurs with Deye based on reviews on YouTube. They say you need a 20KVA generator to charge it. Maybe the experts will explain why. |

Hello house. Please I need advice on my connection. Breakdown of my unit. Solar 150w x2 Inverter is 12v 500w. 200ah battery. For faster charging, do I connect my in series or parallel . Max watt allowed for my unit is 300w

From some reviews, the basic challenges gradually facing Lithium is the use of less quality cells from most of these Chinko guys. The quality of these cells is a function of the durability of these battery System. Is there anyone that would want to get some cells from Alibaba? So we can collabo in the shipping of these batteries to Nigeria. Please any let’s indicate so as to reduce cost |

adrusa: my brother, as you know already resting voltage differs for various battery chemistries: nimh, nicad, lifepo4, lito, etc the 50.8v for my lead acid battery bank doesn't drop much during the night even under very heavy use, that is why battery bank sizing matters a lot. i doubt if mtn, glo, and all other telecoms mast operators including banks will be bothered whether their battery banks rests at 53v or 56v at sun down provided the batteries are delivering as expected with minimal or no supervision. we can go on and on about which battery chemistry is superior to the other (on paper) but the bottom line for them and for me too is value for money spent. 2 Likes |

Hi All, please does anyone know how to handle this. My inverter reads a higher volt than the BMS/meter on the battery. This just started a couple of days ago but it has happened last year. Can’t how it sorted itself out. Sometimes, the inverter volt gets so high that the inverter trips off for overloading. Meanwhile, the BMS app says it’s fine and there is no overload. Has anyone experienced this before? The first 29.3 is the battery volt shown by the inverter. It trips off at 30. Usually when the battery is full. The second is the meter on the battery which shows 26.4 volt and what the BMS app also says. @ojeysky @mcfopt @Valto @earthrealm Anyone with this experience please your input is needed.
