sentix:I once experience that scenario, I went on youtube to see tutorials. Although I bought a new soldering iron from aliexpress that heats up in 5 seconds and the rest was history. 2 Likes 1 Share |

officialfestus:Good job,but the discharge and charging wires are too small |
Re: Diy Lithium Ion Like-minds by officialfestus(m): 7:00pm On Nov 26, 2023 |
obinna37:the capacity is just 40ah, by the way the wires for the discharge and recharge are pure coppers. |

@dollarnaira Please how do I make use of the buck converter? Can use my laptop charger to charge it using the buck converter to step down voltage? |

High quality 18650 lithium ion cells are still available for N500 per cell. |

My UPS turns on and off, after idling for 3 years, please what could be wrong with it? |
Re: Diy Lithium Ion Like-minds by officialfestus(m): 9:10pm On Dec 10, 2023 |
It seems this board is faulty after idling for years without use, because the UPS tries to power on but it immediately cut off power. can I make use of the transformer without the board? valto dollarnaira |
Re: Diy Lithium Ion Like-minds by Penuelseun(m): 5:42am On Dec 11, 2023 |
officialfestus:Nope, get another inverter or a new board, you can take the board to a technician to help you repair it 1 Like |

Hi, I want to know if I can replace dead batteries (10000mah) inside a mini UPS with lithium batteries.

Re: Diy Lithium Ion Like-minds by dollarnaira: 2:06pm On Dec 11, 2023 |
aieromon:You can but do not charge with it. |
Re: Diy Lithium Ion Like-minds by aieromon(m): 2:22pm On Dec 11, 2023 |
dollarnaira: That defeats the purpose. Do you have any idea where I can get replacement lead acid batteries? |
Re: Diy Lithium Ion Like-minds by dollarnaira: 3:26pm On Dec 11, 2023 |
aieromon:The above pix are lithium ion batteries Do u want to replace the lead acid with lithium ion batteries? |
Re: Diy Lithium Ion Like-minds by aieromon(m): 3:36pm On Dec 11, 2023 |
dollarnaira: Yes, that was my intention but you mentioned the charging issues. What are my options? I need a portable UPS for router only. |
Re: Diy Lithium Ion Like-minds by saint2ace(m): 5:57pm On Dec 11, 2023 |
aieromon: Depending on the space of the UPS, you can use cylindrical cells as replacement for the above pouch cells. The power density defers as the pouch cells are more power dense and lighter in weight but all else remains the same, assuming my brain serves me right . You should be fine with good 18650 cells, just solder terminals same polarity as the original and u're good to go... |
Re: Diy Lithium Ion Like-minds by aieromon(m): 6:18pm On Dec 11, 2023 |
saint2ace: What about the charging? |
Re: Diy Lithium Ion Like-minds by Yujiro: 7:27pm On Dec 11, 2023 |
Who have a 8s BMS with active balancer? |
Re: Diy Lithium Ion Like-minds by saint2ace(m): 11:04pm On Dec 11, 2023 |
aieromon: It should charge the same way you charge the pouch cells as both have the same charge profile and algorithm or is there another direction to Ur question? 2 Likes |

Re: Diy Lithium Ion Like-minds by saint2ace(m): 6:01am On Dec 12, 2023 |
aieromon: U're the one with the equipment not him. I'm asking you how u used to charge it before the cells started bulging, that will allow anyone contributing to make an informed submission. Cheers |
Re: Diy Lithium Ion Like-minds by aieromon(m): 7:10am On Dec 12, 2023 |
saint2ace: Ok, sorry for the mix-up. The mini UPS came with a basic charging cord, same type used by rechargeable lamps. |
Re: Diy Lithium Ion Like-minds by saint2ace(m): 5:11pm On Dec 12, 2023 |
aieromon: If the charging module inside is still functional then u'll have no issues with charging as the chemistry and charging behaviour for both pouch and 18650 cells are the same. 2 Likes |
