Q1: What are the environmental features of this battery?
The battery is made from lithium iron phosphate (LiFePO4), an environmentally friendly material that does not contain heavy metals or rare metals. It is safe and stable, not prone to burning or exploding under high temperatures, impacts, or short circuit conditions.
Q2: How should this battery be maintained to prolong its lifespan?
Regularly check the battery's exterior and connections to keep them clean and dry. Avoid keeping the battery in a state of overcharge or deep discharge for extended periods. Be mindful of the ambient temperature during use; avoid charging in extremely cold conditions.
Q3: What are the installation requirements for this battery?
The battery can be installed in any position as it does not contain acid. Ensure that the battery is securely mounted to prevent vibrations and impacts during movement.
Q4: How long do BetterESS batteries last?
Our LiFePO4 lithium iron batteries can provide 2000+ cycles, which is significantly more compared to the 300–500 cycles typically found in lead-acid batteries. The service life of LiFePO4 batteries is 8 to 10 times longer than standard lead-acid batteries.
Q5: Are your batteries safe?
Yes, our LiFePO4 batteries are designed with safety in mind. They are manufactured using Automotive Grade LiFePO4 Cells, offering higher energy density, no memory effect, and more stable performance. The stable chemical structure of LiFePO4 ensures they do not burn or explode, even under high temperatures, short circuits, impact, or drops.
Q6: Are there any special handling or maintenance tips for this battery?
The LiFePO4 battery requires minimal maintenance. However, it is recommended to regularly check connections and ensure the battery is kept in a dry and ventilated space. Avoid exposure to extreme temperatures to prolong battery life.

Die Qualität der batteriezellen ist…
Die Qualität der batteriezellen ist sehr gut.
Es hat alles reibungslos geklappt von der Bestellung bis zur Lieferung....nun hab ich meinen selbst gebauten batteriespeicher seit 10 Tagen in Betrieb und hab seitdem keinen Strom mehr vom Netz gebraucht.
Ich werde etwas später wieder bei ihnen einkaufen.

Alles bestens geklappt! Empfehlenswert!
BetterESS hat mir zuverlässig einen Sendungstermin und zwischendurch Statusnachrichten geschickt, was ich sehr gut finde. Die Bestellungen haben bestens geklappt. Die Ware ist zuverlässig zum angegebenen Termin versendet worden und sicher verpackt in einem 1A Zustand angekommen. Ich bin vollstens zufrieden und würde meine nächsten Akkus wieder hier bestellen. Ich kann BetterESS ohne Einschränkungen weiter empfehlen! Danke!
