This waterproof variant is specifically engineered for outdoor and marine use. With an IP67 waterproof rating, it effectively prevents dust ingress and can withstand immersion in water up to a depth of 1 meter for a duration of 30 minutes.

Trickle charging is not acceptable for lithium batteries. Charging a LiFePO4 battery with a trickle charger not designed for this type of battery could lead to overcharging or damage due to the different charging requirements of lithium batteries compared to traditional lead-acid batteries.

For a complete charge of a 12V LiFePO4 battery, a charger with a voltage ranging from 14V to 14.6V is necessary. If a charger with a lower voltage is used, it can still charge the battery, but it won't reach full 100% capacity.

Yes, you can. But 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.
