I reside in Dutse Alhaji but I have a place in gwarimpa where you can meet me...


But I don't have any finish stock on ground at the moment except what am working on...

samoney:
i tried calling you yesterday u didnt pick i can come around to see you so we can discuss i got some jobs for you

Boss,

Here we go, If the capacity is rated 42AH at 3.7V, we assume all cell with 3.7v are in parallel.

In order achieve 14.8v, 4 cell will now be in series 4s.. then parallel, that mean 42AH will be divided by 4. That is 10.5AH at 14.8v

Hint: if you have a 4 cell rated at 3.7v 2500mah, it simply mean 3.7V 2.5AH..
Connect in series you have 14.8V at 2.5AH
connect in parallel you have 3.7 at 10AH

For power or energy capacity simply multiply V X AH
14.8 * 2.5 is 37WH, same as 3.7 X 10

What can I power with 37WH?

if your appliance is 37w.. this battery capacity will last only 1hour
If your appliance is 3.7watts this battery capacity will last 10 hours

Dam5reey:


When in parralel voltage is kept low, hence higher capacity..
Series connection increase voltage and reduce capacity..

Capacity will reduce 4times since the voltage has been increased 4 times..

The Total capacity remain the same in both case but, 42AH looks big if you don't know the rated voltage...

Hint:
42AH is a capacity at 3.7V, which is the same as 14.8V at 10.5AH
But if he state 10.5AH it looks smaller

42 * 3.7 is 155.4Whours
14.8 * 10.5 is also 155.4Whour

But 42AH rated @ 14.8V is higher in capacity.. 621.6WH

Sir I'll like to order for one of your packs, thou I have the normal Telecom ba3 hooked up to power grid and solar panel, but presently our tranformer is down and the rain has been misbehaving for some days now so not enough sunlight to charge my battery so I'll like to order for one due to the portability of your product so I carry to my office and charge but my question is can I charge with the normal souer intelligent charger because I already have that, please I await your response.

I believe most of us knows what power bank is.

But this is bigger and better, firstly let me enlighten some of us who doesn't know what power wall is.

Power wall are arrays of 18650 lithium cell arranged in series and parallel to achieve required capacity, this power pack could range from 24ah to even infinity so long as you have the cells.


Reasons why you should chose lithium over lead batteries.

1. They have longer life span than lead acid batteries

2. They recover easily from over discharge

3. They are lighter and far less bulky than lead acid batteries.


This power pack could be used with solar panel, charged with PHCN or gen.

But for charging with PHCN or Generator then you have to order alongside it's charger.


Spec of power pack and price.


42ah battery with 20a charge controller, no charger. 13k

84ah battery with 20a charge controller, no charger. 25k

Without charge controller cost a little less.....


The charge controller are inbuilt and enable you to charge directly with your solar panel.


Charger is 5k.....


I harvest my 18650 cells from very good source and proper integrity check are done on each cells before they are used, so my capacity are genuine.

If you want huge power wall, I can set that up too.


Please feel free to ask any relevant question

You may not need an inverter if it's for just laptop...

I can set it up just to cut down cost of buying an inverter, with universal car cigarette charger like this one.

To get my battery pack you have to place order and then I will tell you when your pack will be ready.

Preparing a pack takes about a week at most two weeks. you are not paying until your pack is ready. Just send me a text with your full details to order

I can weigh bill to anywhere in Nigeria if you like.

My 42Ah pack is about 620w so divide by your laptop watt to get the number of hours.

ameh99:
100ah pack....

ameh99:
100ah pack....

ameh99:



42ah can power just your laptop for up to 30hrs depends on how many watt you device consume.

Dami12345:

Price?

Trippledots:


How much? I'm about purchasing a battery for a small solar build. Kindly reply asap.

ameh99:


48k without charger..

Trippledots:


With charger, how much? And how long to prepare a 2packs?

Can we talk on whatsapp?

ameh99:
Please note that for now I only use new cells. And also have 18650 2600mah 3C for sell.
