CHARGING

PRIOR TO INITIAL USE, ENSURE BATTERY HAS TAKEN FULL CHARGE AND IS IN A FULLY CHARGED STATE. OUR BATTERIES MAY NOT BE SHIPPED FULLY CHARGED!
MAKE SURE THE CHARGER’S INDICATOR LIGHT HAS TURNED GREEN AND WAIT FOR 30 MIN. ELAPSE BEFORE UNPLUGGING, CHARGE TIME VARIES FROM MODEL TO MODEL!

When charging your battery, please follow the provided sequence below:

Attach Battery Charging Connector to Charger (This will vary depending on your selected model and configuration of battery)
Attach Charger to 110VAC Outlet
When Charging you should observe a RED LED Indicator: this indicates that the battery is currently in the Constant Current (CC) charging phase
Wait for a GREEN LED Indicator: this indicates the battery is currently in the Constant Voltage (CV) charging phase 5. Wait 30 MINUTES before unplugging the
Charger from the 110VAC Outlet FIRST and then disconnecting the Battery from the Charger SECOND

DISCHARGING (STANDARD, SERIES/PARALLEL <0.5C DISCHARGE)

Make sure your load accepts 12V nominal voltage.
Ensure the connection between the battery and the load can handle the current draw. Please consult references for the appropriate wire type.
The maximum continuous discharge current is 35A. Please make sure your electrical load consumes a current less than 35A continuous and 420 watts of power.
The battery outputs steady voltage until little capacity remains, do NOT rely on voltage as an indicator of remaining capacity, Aegis Battery recommends the usage of an In-Line Watt Meter for conveyance of accurate battery discharge telemetry.
Series: Each battery must be charged separately and given a full charge before connecting in series.
Parallel: Only connect batteries with equal state of charge in parallel. Also, measure the internal resistance of each battery and only use batteries with closely matched internal resistance of the same make, model and batch origin. It is highly recommended that resistors be used to achieve equal internal resistance between batteries and to add fuse(s) to the circuit for safety reasons.

SAFETY GUIDELINES

Please adhere to the following Safety Guidelines in addition to all disclosed information when using your battery. Any damage incurred as a result of a failure to adhere to the recommended usage guidelines as collectively disclosed may result in a partial or complete voiding of the warranty as provided upon purchase of this battery product. Additional Safety Guidelines are as follows.

Do not disassemble and/or attempt self-repair
Do not short circuit positive and negative terminals
Do not use lead acid chargers as they will cause damage to internal hardware
Do not dispose in normal refuse bin, recycle this product only at designated facilities
For long term storage, fully charge the battery and then discharge to 50% of the full capacity
Do not leave the battery unattended for more than 6 months or in the presence of children
Do not use the battery in or expose the battery to extreme temperatures

FAQ

+ How long will my battery last?****

– Several factors that affect battery life including weather, temperature, recharge cycles, depth of discharge (DOD), discharge current, charging current, charging method, vibration and duration of static use can all have dramatic effects on battery life. A properly maintained battery should last 1000+ charge discharge cycles or three times as long as lead-acid use in similar conditions.

+ Can I use lithium ion batteries with other types of batteries?****

– No. If different types of batteries are used together, or new batteries are used with old ones, the difference in characteristics such as voltage, capacity, and/or internal resistance may cause uneven discharge between the batteries leading to cell damage potentially resultant in fire.

+ Is it okay to use a universal lead acid charger with high enough charging current?****

– Using a lead acid battery charger is not recommended because they charge at a lower 2.30V to 2.45V per cell in addition to charging in multiple stages with a final float charge setting. This is distinctly different from the Li- Ion 2-Stage charge profile. Mixing of chargers between chemistries will result in damage to the battery.

+ Can I connect two of the same Li-ion batteries together for more voltage/ capacity?****

– Linking our Li-ion batteries in series or parallel connection is NOT RECOMMENDED and may exceed factory recommended usage parameters. It is recommended to purchase a single battery with the requisite capacity and discharge characteristics. Our Battery Management System (BMS) is designed for operations within a singular battery unit and we cannot guarantee operability of multiple batteries connected together regardless of configuration. If, however, multiple batteries are required please ensure 1) the batteries are from the same batch 2) the batteries are of the same make and model and 3) peak discharge is maintained at <0.5C peak.

+ My battery will not charge/discharge?****

– There are multiple reasons including but not limited to 1) charger failure, 2) external damage to battery has compromised either the cell pack or BMS, 3) battery voltage has fallen to zero in one or more cells, 4) there is a connection error within the pack, 5) a malfunction(s) has occurred within the BMS component(s) or in extreme cases 6) extreme high/low temperatures may be inhibiting charging efficiency of the cell pack itself.

+ Can I jump start a dead lithium ion battery?****

– It is not recommended. Li-ion batteries enter an elevated sensitivity state when empty and the introduction of unmodulated amperage in this state will damage the cell. We highly recommend using our chargers to recharge a fully discharged Li-ion battery as our chargers have the sensing circuitry required to modulate charge current to optimally recondition fully discharged batteries.
