XBERSTAR 18650 Battery Holder,12V 3S 7P Li-ion DIY Case Holder for 18650 Powerwall Battery Pack Spot Clamp (Black)

I have converted my UPS batteries to lithium with these. Pretty straightforward to build, doesn’t forget a BMS! It all fits in the battery box and silicone glued together. Done with the lead acid batteries!!!

Made myself a 21P battery and added a USB converter. Works perfectly as a power backup for my cabins WiFi and camera system. Would buy again in a heartbeat.

For the most part okay for the price. But one had a chipped corner in the lid. Will keep it and use it. Not worth sending it back.

I had to cut the ends off the battery holders to fit it into the case but besides that it matches the size of my APC batteries so it was any easy swap. Worth it to get it in a short amount of time over other suppliers.

Building a back up power supply

I like the design, looks just like the AGM battery. The great thing is that the bad batteries can be removed easily, and the whole series, parallel battery can be rebuilt over and over again using the same case. The battery holders are included to space the batteries apart so they cannot rub against each other. The top snaps on, no glue needed.

Perfect!

sucks i ewas really waitting for this

Produit pas complet pour le montage, pourtant il me semble que dans l'annonce ça y était. Mais j'ai regarder trop tard....

enligt beskrivning

Does wot it.says on the rin

Grundsätzlich einwandfrei. Nur die Zellhalter sind für 18650er Zellen sehr eng. Ich hatte Zellen mit einem etwas dickerem Schrumpfschlauch drumherum. Diese passten nur mit Kraft hinein, was der Funktion keinen Abbruch tut. Der Deckel rastet nicht ein und muss um zu halten verklebt werden. Kontakte sind sehr fest und lassen sich gut anlöten. Sonst sehr gut

When you need a DIY battery pack. Good case.
