❓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.
