Correct battery?

[Rod Fuller]

Ordered Li -ion 48V 20Ah, delivery note says 3.2V 10A
Before using this battery, I need to know if I have the item that I ordered
double cell would give say 15 x 3.2 = 48, current output?

Perhaps a link to what you ordered might help.

Battery was supplied by Shenzen BOTE Energy Technology Co. Ltd., as stated their test report aroused my suspicions.

I expect there's a capacity limit for shipping, so the test report shows the battery as being under this. I've had similar test reports with chinese batteries.

That's one monster of a battery. It must weigh 12kg. What are you going to use it for?

Not at all
Dimensions of metal case:L34.5, W15, H 8cm. Wt 4Kg
Manufacturer's spec:20Wh per cell, 100Wh per battery
I still do not relate this to 48V & 20Ah

Did you put it on the scales to weigh it. My 36v 10ah Headway battery weighs 4 kg. It has 12 10ah cells. Yours should have 32, so should be 2 1/2 times heavier. Also, it should be 33wh per cell.for 1056wh total. The 100wh is only for the shipping paperwork because that's the maximum you can send.

Yes I did weigh it, apart from that from what you say I am still not convinced I have the battery I ordered.

 

[Deleted member 4366]

If you weighed it, what is the weight? Are you saying it's really 4kg?

 

[trex]

you should see 38120S 10AH printed on the side of the cells.

maybe, but I wanted 20Ah! Nothing printed on the metal case.

How much does it weigh on your own scales?

You can check the size of the cells easily.
38120 cells are 38mm wide, 120mm high.
If not, give us the dimension of the pack or post picture we'll check for you.

Dimensions of battery box were given previously wt between 4 & 5Kg

that case holds only about 48V 10AH in LiFePO4 top.
I don't think they sent the right battery.

Thanks for that. I am trying to get a response from China.
