FAQ

What type of battery is LiTime 12V/16V lithium charger suitable for charging?

This LiFePO4 battery charger is born for 12V and 16V LiFePO4 batteries. Its versatility makes it an excellent choice for a wide range of applications, ensuring that your devices operate efficiently and reliably.

Additionally, the charger can protect against over temperature, output short circuit, reverse polarity connection, output over voltage, output over current and output under voltage, giving you peace of mind during the charging process.

What are the differences between the waterproof version and classic version?

This waterproof version is specifically engineered for outdoor and marine use. With an IP65 waterproof rating, it is designed to withstand harsh environmental conditions, ensuring reliable performance even in wet or dusty environments.

In addition, the upgraded IP65 connector comes with waterproof caps that keep the port protected even when disconnected.

Can I charge LiFePO4 to 100%?

Yes, you can. However, charging a battery to less than 100% and avoiding complete discharge always increases cell longevity. Similarly, maintaining operation within the 20%-80% state of charge (SOC) range will prolong the life of lithium batteries. In the case of LiTime deep cycle lithium batteries, they can withstand over 4000 deep cycles at 100% Depth of Discharge (DOD), over 6000 cycles at 80% DOD, and more than 15,000 cycles at 60% DoD.

How do I know if my battery is charging correctly?

LiTime 12V/16V LiFePO4 charger includes LED indicators to show the charging status, which lets you know if the battery is being charged correctly.
