[stefsbattery]

I need two more batteries from Greenworks . I am from Montenegro (small country in europe) and i need it for my string trimmer.
Now shipping is soo expensive and hard to get. So i was think if can do this. This is cheapest i can find.
But this : LINK and this link 2 , and find some electirician to put it together. My question is, are this possible and secure?

I've put together quite a few power tool batteries as a hobby. If you want, I can help.

No idea what cells you linked since I don't have a temu account.
Here are some cheap brand name cells that will work

Thank you for links, i will consider this.
What i want to know, how i can know that batteries will be 24v 4a? It can be 5a or similar, but 24v is a must and 4a is a minimum.
I dont know nothing about this so sorry if this question is nonsence to you.
Right now i can trim about 30-40min, and with another pair of batteries i can get another 30m-1h(depends of battery), which is enought for me.

The greenworks battery case you linked needs 12 cells. 2 parallel rows of 6 cells. If you use the Samsung 25R cells you will get 5Ah, if you choose the red Sanyo cells you will just barely get 4Ah.

Another option is to just buy 24v batteries with cells in them. https://a.aliexpress.com/_EG4aYyK

These could last a year or two. I had a greenworks 40v battery from AliExpress that lasted me 2 years. The way it died was from corrosion, if I had known that I would have sprayed some clear varnish or used some nail polish.
And if the battery does die after some time then you can just replace the cells with brand name ones. This is the most economical solution in my opinion.

Don’t trust any cells where the seller doesn’t know what they are selling. They are describing them as lithium polymer (lipos) in their description.

 

[eee291]

For about a 10€ difference you'd be stupid not to buy those and just run them till they die. You can always replace the cells afterwards.

The problem is that this batteries from aliexpress dont ship in my country (Montenegro), i will be happy if i can buy them but they not ship. So right now only way i see is to get a shell and then get batteries and find someone to put this all together. I also try ebay, batteries dont ship.

 

[stefsbattery]

Cheapest in my country is this, which is soo expensive:
BATERIJA 3.7V Lithium 18650 2200mAh - Quantum Elektronika, BATERIJA 3.7V Lithium 18650 2200mAh - Quantum Elektronika, https://ananas.me/proizvod/gembird-litijum-jonska-18650-baterija-10c-2500-mah-plava/2178578 .
Thats the reason why i go to look in ali, temu and similar.

 

[eee291]

The issue is that even if I weld a pack, the battery still has to go through customs and be taxed again.
And for some reason Nkon does not list Montenegro, maybe they have some high tax on batteries or it needs to be shipped as hazardous goods.

 

[stefsbattery]

correct, cheapest way is temu, Montenegro on Temu dont pay taxes becasuse temu allready include taxes for Montenegro
But i am not sure about battery quality.

 

[eee291]

If you like I can buy the greenworks battery or the case and cells and then ship it to you.

Or try Ebay, I have thro' Ebay ordered bits and pieces I needed from china which I could not get directly via Aliexpress, I have contacted sellers directly and they have taken the order for an alternative item and sent the one I wanted and that has been for a 48v battery.

Are you sure you can send battery?
I try ebay, only option is this, but its pricey because of shipping, and plus taxes, it will be about 150usd. Which is extremely big price for just 1 battery.

I tried everything, thats the reason why i ask here about alternative ways. There is a lot of shipping forwarders, but price is about 50usd for shipping plus taxes plus battery omg.

 

[dgc]

Is this the same battery

 

[stefsbattery]

I think it is. I cant find it because i am from Montenegro.


believe me i will instantly buy 2 if i can get for 45usd.

 

[dgc]

It's a joke, I assume any local suppliers charge thro' the roof.

 

[eee291]

2 Batteries are €53 with shipping. I can buy them right now.

what, original? Are you sure? Can you send link? Are youre your post can send?

 

[eee291]

I said nothing about original, like I said before, buying just the cases is almost as expensive as the batteries with cells in them.

 

[stefsbattery]

i read that nonoriginal can explode so i am afraid.

 

[stefsbattery]

give me advices, is soo anoying that i can only trim about 40-50 minutes. Just one pair more will make a extremely big amount of difference.

 

[eee291]

I could weld you those packs with Samsung 25R cells. Material cost ist already €110 and then add work, shipping and import duty and you're looking at probably over €200 for 2x 5ah batteries

 

[stefsbattery]

oh, soo expensive, plus taxes in my country. it will be about 250.

 

[eee291]

Indeed, that is why I recommended buying 2 Chinese made packs and once the cells die after a year or two you can replace them with high quality ones.

i read that they can explode when charging. Thats the reason why i am afraid.
