❓ Frequently Asked Questions
Q1: Do you have a Minimum Order Quantity (MOQ) limit?
No, there is no MOQ limit. A 1-piece sample order or small quantities are available for testing and evaluation.
Q2: What is the typical lead time for orders?
Standard product samples take 3-5 days, while bulk orders typically take 3-4 weeks. Customized products require 3-4 weeks for both samples and bulk production.
Q3: How long do LiFePO4 batteries last?
Our LiFePO4 batteries provide over 4000-6000 cycles, which is 8 to 10 times longer than standard lead-acid batteries (which typically last 300-500 cycles).
Q4: Does the BMS have low-temperature charging disconnect protection?
Yes. The BMS includes low-temperature protection cut-off to prevent damage. Charge protection activates at 0ºC ± 4ºC, and discharge protection at -20ºC ± 4ºC.
Q5: What are the options for charging these batteries?
We recommend using a dedicated LiFePO4 charger (14.6V for 4-string). You can also use photovoltaic solar panels with an MPPT controller, or an inverter with a built-in AC to DC charging function.
Q6: Are these batteries safe for indoor residential use?
Yes, our LiFePO4 batteries use automotive-grade cells with a stable chemical structure that is resistant to burning or exploding. The built-in BMS protects against overcharge, deep discharge, and overheating (disconnecting at 75°C).
