I would get 4 or 6 and I could power a great deal of the house with it.

 

Too good to be true for this price?

From the info i see your guys share on used batteries the sellers online on Lazada and Shopee listing the Nominal Ah on batteries and not the real, so maybe can expect 60% effective Ah?  

 

From this topic

 

So if 60% only that would mean 60Ah, for that price it still isn't that BAD ????

If that really is a 48V x 100Ah pack I think Elon Musk might be interested

18650 = 3.7v@ 3500mahr.

39 x 3.7 x 3.5 = 500ahr = 0.5kWhr.

Thx @BritManToo ????

 

Edit: 1 question though, where then comes the 100Ah from. Their calculator broken? ????

I reckon they're using pretty naff 2.5Ah 18650s.

 

Pack is 3P13S so I divided 100Ah by 39 cells giving 2.56Ah per cell.

 

In reality 3 x 2.5Ah in parallel gives 7.5Ah which is the real capacity.

So to get 100Ah, you would need 100Ah/7.5Ah = 13 Packs. Correct?

 

And 13 * 3566 = 46358 THB ????

 

As usual: if it sounds too be good to be true then it usually is (<- Strikes again)

Even 13 packs couldn't fix this scam as you need 14 x 3.7v cells to make a standard 48v pack and these muppets only use 13.

Ebike batteries are notorious 'mislabelled'

My 48v30Ah battery is 1/3 the size of 

my 48v10Ah battery, which goes 3X as far, at lease.

And only cost 2X more. shy of 6k baht vs 3000

 

I was not surprise or really expected it to meet the posted specs.

I was enough for my needs, as only need about 15-20kms a day,

It's like amps or speakers , 10000 watt pmpo , don't even try to get more then 10 watt out (or in) them , as it would fry .

The list goes on and on and on ...

They just add a few numbers nothing even remotely related to a real value . Just think about stuff and check out what is possible and what not ( and stay away from high numbers , as they always are fake ( unless priced similar ))
