Please can I parallel 12v 70ah lithium ion battery to another 12v 35ah lithium ion battery to make it 12v 105ah. I saw where they said that lifepo4 can be parallel together. |

So recently I have been thinking, how do you charge your 3s battery with solar controller? Due to the fact that most pwm controller has max bulk charge at 14.4v. Don't you think running 4s is a more better option |
Re: Diy Lithium Ion Like-minds by Penuelseun(m): 1:38pm On Apr 16 |
Obnoxious2001:the controller I posted up there has both 3s and 4s lithium profile, 4s configuration is not good for most 12v inverters in the market as the maximum voltage they can work with is 15.5v, 3s will also limit you to around 50% of your battery capacity as most inverters shut down around 10.5v. 7s and 14s is the best configuration for li-ion cells 3 Likes |
Re: Diy Lithium Ion Like-minds by Obnoxious2001(m): 3:15pm On Apr 16 |
Penuelseun: I get your point very well. How ever, on 4s low battery cut out is going to be around 12v....., Which is too early. Kia. Make I see the one I go do first |

I have this spare 800/1600 Pure Sine wave sachet inverter for sale. Price - 50k firm. Location - Oshodi/Isolo, Lagos

Re: Diy Lithium Ion Like-minds by Wizyoung(m): 10:55pm On Apr 20 |
The bosses in the house... I greet you all. How can one tell that an inverter is Pure sine wave and not modified sine wave at first use? It has come to my notice that many modified sine wave inverters are advertised as Pure just so they can be sold at a higher price. |

Re: Diy Lithium Ion Like-minds by eghos12(m): 9:07am On Apr 21 |
officialfestus: Bro please explain how the usage with the ups has been. What volt does it trip off. |
Re: Diy Lithium Ion Like-minds by officialfestus(m): 9:41am On Apr 21 |
eghos12:usage from a 1kw diy lithium ion (12v 3s) battery, usage has been poor, because it shuts down at 11v powering just a 90w tv for two hours, the UPS is not efficient with power, I ordered a 2600w pure sine wave sachet inverter from aliexpress and it has arrived my state, hopefully I get it this week, I'll keep the house updated on how it goes. |

Got a 385w Canada panel, I hope to get another jinko 400w soon.

officialfestus: You know you are buying mppt charge controller sha because of this size of panel ba |
Re: Diy Lithium Ion Like-minds by Penuelseun(m): 12:35pm On Apr 21 |
eghos12:he can divide the cells into 2 and use with the pwm controller if he knows his way around it, voltage will be reduced from 36v to 18v thereby doubling the current 3 Likes |

Penuelseun: Thank you for this |
Re: Diy Lithium Ion Like-minds by eghos12(m): 6:38pm On Apr 21 |
ksmart027: How is the msw doing does it give bad sound What are the appliances you are using it for |
Re: Diy Lithium Ion Like-minds by eghos12(m): 6:39pm On Apr 21 |
So my diy enthusiast wast the suppose cut off voltage of 3s li ion battery pack when connected to an inverter |
Re: Diy Lithium Ion Like-minds by ewizard1: 6:52pm On Apr 21 |
eghos12: A 3s Li-ion is at 0% at 9v (3v per cell). However, you won't find and inverter that'll go that deep before it shutdown. |
Re: Diy Lithium Ion Like-minds by ewizard1: 6:53pm On Apr 21 |
eghos12:A MSW inverter would ALWAYS give bad sound to inductive loads. |
Re: Diy Lithium Ion Like-minds by eghos12(m): 7:16pm On Apr 21 |
ewizard1: Ok Na to gather body buy pure sine wave o |
Re: Diy Lithium Ion Like-minds by eghos12(m): 7:18pm On Apr 21 |
ewizard1:I which we can see inverter that goes below 10v above 70% would still be okay |
