eghos12:Funny enough, I don't get humming sound when powering my fan, I use it to power my tv, home theater, fan, phones and bulbs. |

eghos12: Satchet inverter can go below 10v from my personal experience, the load on the inverter matters, just powering single 5w bulbs on an inverter can make the inverter go to 9v |

ksmart027: Do you use normal standing fan or rechargeable |
Re: Diy Lithium Ion Like-minds by Penuelseun(m): 10:57pm On Apr 21 |
eghos12:victron satchet inverter can go as low as 9v but very expensive 1 Like |

eghos12:I use a 50w normal standing fan most times, but i mostly use a DC fan. |

eghos12:I'm getting a pwm, the exact type penuelseun posted here. |
Re: Diy Lithium Ion Like-minds by eghos12(m): 11:50am On Apr 22 |
officialfestus:Don't buy it if you have not paid o. except you can cut the panel as penuelseun has said. You better go for mppt because it going to be slow when charging your battery due to the fact that pwm controller can not convert excess voltage to current, it will only take the 18v needed to charge the battery and expel the rest as heat.. but mppt will convert it to current and send it to the battery. 1 Like |

eghos12:ok, I never buy am thanks. |

ksmart027: Msw cut off at 10v is cool depending on the amp of the battery used. |

officialfestus: Afa give me your WhatsApp no I stay edo too I want to ask some edo solar questions |
Re: Diy Lithium Ion Like-minds by officialfestus(m): 3:14pm On Apr 22 |
eghos12:ok bloodline. E they my signature now. |
Re: Diy Lithium Ion Like-minds by officialfestus(m): 10:06pm On Apr 23 |
My inverter came today.

Re: Diy Lithium Ion Like-minds by officialfestus(m): 10:08pm On Apr 23 |
It was worthy every Penny as it can go as low as 9.4volt, with a load of 90w. 2 Likes

officialfestus: Congratulations. Very compatible with lithium but severe damage awaits LifePO4 users. So dont use it with LifePO4 oooooo unless a bms at 3v cut off per cell is attached. Enjoy!!! 1 Like |

dollarnaira:ok sir, thanks. |
Re: Diy Lithium Ion Like-minds by zenith4biz(m): 11:29am On Apr 26 |
officialfestus: Hope your cells are well balanced with BMS attached, if not you will be killing some cells at that voltage |
Re: Diy Lithium Ion Like-minds by officialfestus(m): 2:30pm On Apr 28 |
zenith4biz:yeah, I even plan on buying an active balancer soon. |

Penuelseun:can this be possible with jinko 440w solar panels |
Re: Diy Lithium Ion Like-minds by Penuelseun(m): 9:28am On Apr 29 |
orkman:I don't think so |
Re: Diy Lithium Ion Like-minds by orkman(m): 5:06pm On Apr 29 |
Penuelseun:okay. Thanks |

flotwz: You'll need a digital multi meter and a timer (clock) or your phone time. First connect the battery to the meter, if the battery is fully charged, you'll get 4.25v or 4.45v pending on the battery type, now connect the fan to the battery while the meter is still connected, once connected, time it, I time mine 1mins, sometimes 2minis. (This is where the clock comes in). If it's a good battery, it should read 4.24v or 4.28v, now that's the voltage drop. (Eg Below). That's how to know a good battery, if it drops below that, it's bad, even if it drops to 4.00v, connecting it together with other cells in series or parallel is risky. Let's take for example, if the battery reads 4.25v while connected to the meter, then reads 4.20v when you connect the fan (voltage drop), that is 4.25 - 4.20 = 0.05. After your 1mins has enlaps, disconnect only the fan, now the battery voltage will rise back to the default voltage it was which is 4.25v, some will rise to 4.24v then slowly reach 4.25v. Now that's a good battery. Any battery that doesn't rise back to it's default voltage is close to going bad. If after your calculations and yours drops below 0.05, don't mix it with others that is above 0.05. 1 Like |
