To avoid contact resistance, the following points must be observed:
✔️ Thoroughly clean the battery terminals with ethanol or pure alcohol to remove oxide layers.
✔️ The terminals must not be touched with greasy fingers – they must be absolutely grease-free and clean.
✔️ Ideally, the contacts should be cleaned with a brass brush or fine sandpaper (grit 1000).
✔️ The contact surfaces of the cell connectors must also be carefully cleaned.
❌ The use of assembly greases, copper paste, or similar substances must be strictly avoided – they cause contact resistance, which can lead to heat generation and measurement errors during operation. As a result, the full capacity of the cells cannot be utilized.
🔧 Tighten the M6 screws with a torque of 6 Nm.

Diese Batteriezellen haben meine Erwartungen übertroffen. Sie sind brandneu und in einwandfreiem Zustand angekommen. Die Leistung ist stabil und die Zellbalance ist sehr gut. Ich verwende sie in einem Solarspeichersystem und habe keinerlei Probleme festgestellt. Der Verk?ufer war professionell und die Lieferung erfolgte schnell. Insgesamt ein sehr hochwertiges Produkt, das ich gerne weiterempfehle.
Ich habe diese Zellen für mein DIY-Speichersystem gekauft und bin sehr zufrieden. Die Qualit?t ist sehr hoch, und die Zellen sind gut aufeinander abgestimmt. Der Innenwiderstand ist niedrig und die Kapazit?t entspricht den Angaben. Nach der Installation l?uft mein System stabil und zuverl?ssig. Auch die Verpackung war sehr sicher, alles kam unbesch?digt an. Klare Empfehlung für alle, die ein zuverl?ssiges System aufbauen m?chten.
J’ai acheté ces cellules pour mon système de stockage solaire et je suis vraiment impressionné par leur qualité. Les cellules sont parfaitement équilibrées, avec une très faible résistance interne. La capacité est conforme aux spécifications, ce qui est très rassurant pour une utilisation à long terme. L’emballage était solide et sécurisé, aucun dommage à la réception. Après installation, le système fonctionne de manière très stable. Je recommande fortement ces batteries pour toute installation fiable.
All batteries have the specified capacity and show no visual defects. Excellent batteries.
Everything has arrived in good condition, well packaged. Tha batteries are perfect!
