XBERSTAR Li-Ion Battery Storage Box 3x7 18650 Holder for DIY Battery Special Plastic DIY kit, Black (Black)

Tight fit, but woks well.XBERSTAR Li-Ion Battery Storage Box 3x7 18650 Holder for DIY Battery Special Plastic DIY kit, Black (Black)

Kit included everything except batteries. Nickel strips spot-welded reliably and are adequate for continuous use at about 200w level. BMS board works as described. The finished product is NOT an exact replacement for a 12v SLA (sealed lead acid) battery even though the physical form factor would suggest such, but the 12.7v terminal voltage is ideal for various 12vdc computer peripherals such as switches, routers, and hubs that one would like to power directly from a battery source. Very useful item. I purchased several, and will do so again in the future.

I know im not the only one that noticed the questions being asked about this product. Im not making fun honestly, but if you wrote a question on this product,please just buy it and take it to a profesional because this are dangerouse if not handled safely. 1 asked do u need a spot welder? If you have worked with 18650 the picture is obviouse that you do need one. Another asked what configuration is it . Description says 12v, if experienced then 3s is the way to go for 12v. If they dont have the knowledge of how to identify or answer there own question than that means that they have no experience what so ever, im not saying there stupid,they just lack the basic knowledge, wich can be fixed with experience with this and by no means touch this. Sorry but im just concered people can get seriousely hurt.

The nickel strip doesn’t line up with the 18650 holder so you’ll end up needing to buy some or make your own. I also noticed that the cells for the positive side don’t protrude a lot so you would have to push the nickel In a bit to get it to make a connection but with that being said it seems to be a solid little kit for a battery pack.Update: even after grinding down the plastic there are edges that push up on the nickel so the weld lifted which is not good if you wrap the pack in shrink wrap because then you’ll have to do twice the work to fix it. This kit is decent but I wouldn’t recommend it to anyone else and I can’t return it because I grinded it.

You'll need a small spot welder to connect the batteries but overall this is a very good kit.

Useless metal part that hooks two 7 links 18650 batteries is very handy to hook, so don't buy this junk. I setup to return is but cost to much to do so!

Good

It was nice to have everything you needed in one package but the holes in the plastic pieces that hold the batteries were to small for the batteries. I had to modify them to get the batteries to fit. I used standard 18650 batteries. 3.6V 2500mah. Some batteries would fit but most had to be really forced and a few wouldn't fit at all. when you got the batteries in the holder, it caused the holder to warp and wouldn't hold its shape. Finally got it all together but it was highly moidified.
