❓Frequently Asked Questions
Q1: What is the lead time for orders?
Standard products take 3-5 days for samples and 3-4 weeks for bulk orders. Customized product lead times are typically 3-4 weeks for both samples and bulk orders.
Q2: How are the goods shipped and what is the shipping time?
We offer air delivery (6-12 days via FEDEX, UPS, or DHL), sea delivery door-to-door (25-50 days), and airport delivery (3-5 days) for urgent heavy packages.
Q3: Does the BMS have low-temperature charging protection?
Yes. The BMS includes a low-temperature cut-off function to protect the battery from damage. Charge protection activates at 0ºC ± 4ºC and discharge protection at -20ºC ± 4ºC.
Q4: Do I need a special charger for LiFePO4 batteries?
We recommend using a 14.6V lithium iron phosphate charger. You can also use photovoltaic solar panels via MPPT or an inverter with built-in AC to DC charging functionality.
Q5: How long do LiFePO4 batteries typically last?
Our LiFePO4 batteries provide 4000+ to 6000+ cycles, which is 8 to 10 times longer than standard lead-acid batteries (which typically last 300-500 cycles).
Q6: Are these batteries safe to use at home?
Yes. LiFePO4 has a stable chemical structure resistant to burning or exploding. The built-in BMS protects against overcharge, deep discharge, overheating (disconnecting at 75°C), and short circuits.
