FAQ
Q: Can it directly replace the original lead-acid battery?
A: Yes, 12.8V is compatible with 12V systems, with adaptive size and consistent positive and negative poles, plug and play; it is recommended to check if the charger supports LiFePO4 (14.4V-14.6V).
Q: Does it support parallel expansion with multiple batteries?
A: Yes, it can be paralleled with up to 4 batteries, with a total capacity of 1600Ah, meeting the demand for large loads.
Q: Can it be used in low temperatures in winter?
A: The standard version can be charged above 0℃; the optional low-temperature heating version can be normally charged and discharged at -20℃, suitable for RVs in northern winter.
Q: How long is the service life and warranty period?
A: 3000+ cycles (70% DOD), usable for 8-10 years under normal use; 5-year warranty (free of charge for non-human damage).
Q: Is maintenance required?
A: Zero maintenance, no need for water replenishment, balancing or regular charging, low self-discharge rate, and slow power loss during long-term storage.
Q: Is it safe? Will it explode?
A: It adopts LiFePO4 (lithium iron phosphate), which has stable chemical properties, non-flammable and non-explosive; built-in BMS multiple protection and flame-retardant shell, safe and reliable for RV use.
