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:
1. Attach Battery Charging Connector to Charger (This will vary depending on your selected
model and configuration of battery).
2. Attach Charger to 110VAC Outlet.
3. When Charging you should observe a
RED
LED Indicator: this indicates that the battery is
currently in the Constant Current (CC) charging phase.
4. 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)
1. Make sure your load accepts
48V
nominal voltage.
2. Ensure the connection between the battery and the load can handle the current draw. Please
consult references for the appropriate wire type.
3. The maximum continuous discharge current is
100A
. Please make sure your electrical load
consumes a current
less than100A continuous and maximum 4800 watts of power.
4. 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.
1. Do not disassemble and/or attempt self-repair.
2. Do not short circuit positive and negative terminals.
3. Do not use lead acid chargers as they will cause damage to internal hardware.
4. Do not dispose in normal refuse bin, recycle this product only at designated facilities.
5. For long term storage, fully charge the battery and then discharge to 50% of the full capacity.
6. Do not leave the battery unattended for more than 6 months or in the presence of children. It
is recommended to charge the battery every three months if it is not used.
7. Do not use the battery in or expose the battery to extreme temperatures.
