Battery Safety and Care

Blue Robotics has a nice description of how to keep your batteries working and how batteries work.

The Wi-Fi module has a simple internal battery protection system to prevent damage your batteries by over-discharging them. The battery will be electronically disconnected when the battery charge falls below 12V, and the battery must be disconnected for at least 10 seconds and a charged battery connected to restart the Wi-Fi.

You should follow these steps to prevent damage to the battery:

• Always use a balance charger.

  • A balance charger compatible with 4S (14.8V) Lithium batteries is required

  • Most users already have a balance charger for their ROV battery.

• Power off the Omnitrack after use using the switch.

  • Running a battery below the cutoff voltage (<12V for a 4S) will likely cause permanent damage.

• Remove the battery from the enclosure whenever practical.

• The supplied battery can run about 10 hours on a full charge. It's good practice to recharge after every use, and to limit the time used to about 5 hours.

• Batteries should be charged to ~60% state-of-charge (SOC) for long term storage. Storage at high SOC (>80%) over time will reduce the battery's usable capacity.

• Shipping regulations require batteries to be shipped with less than 30% charge. Charge your battery before its first use.

IF you use q different type of battery, let us know at Cerulean and we can supply a battery interconnect PCB that does not shut off power at 12V.
