dollarnaira:A 3s LV is at 9v (3v/cell), 12v inverters would shut down at max 10.5v; (3.5v/cell) "Any 12v inverter" would work but not efficient. |

ewizard1: True bro I have an msw dat shuts down at 9.45 and the 2nd one 9.78v. But truth is from 10.5 to 9.78v is roughly 30mins from my test on a 40w load or so. |
Re: Diy Lithium Ion Like-minds by ewizard1: 9:35pm On Feb 23 |
dollarnaira:10.5v to 9.78v is different from 10.5v to 9v The 9.45v is a better one. |

Searching for 12v inverters that would match a 3s Li-ion setup led me to studying the sachet inverter circuitry and I realised why. 1 Like |

dollarnaira:Firstly, the input current at such lower voltage would be higher and require costlier components. Secondly, the High side Mosfets gate driver might not switch effectively leading to shorting mosfets. I once successfully modified a TL494 driver based modified sine wave inverter and it worked. |

I've always been fascinated by all these DIY Setups but a total novice. I will like to delve into it, I don't mind paying to get a good graps of it all. Anyone to teach and guide me? I will really appreciate it. 1 Like |

eghos12:how's your setup fairing? How best is it compared to a powerbank? |
Re: Diy Lithium Ion Like-minds by eghos12(m): 3:05pm On Mar 17 |
officialfestus: Have not used it yet. I want to arrange an array with it. Just got a pwm yesterday, I still need an inverter. |

Good morning boss, did you use insulation for the covering of the pack? Cc dollarnaira |
Re: Diy Lithium Ion Like-minds by dollarnaira: 10:21am On Mar 21 |
officialfestus:Yes Just to keep the batteries from dangling |
Re: Diy Lithium Ion Like-minds by officialfestus(m): 10:28am On Mar 21 |
dollarnaira:did you also use something like this?
|
Re: Diy Lithium Ion Like-minds by dollarnaira: 10:41am On Mar 21 |
officialfestus:What exactly do want to achieve? Used cotton clothes can be cut in different ways. The most important part is to get good insulator for separation of each 's' |
