Connecting The Batteries In Series
Why connect in series?
Connecting your batteries in series has an opposite effect on your system that connecting in
parallel does. In this case, the capacities and current stay the same, but the system voltage is
additive. For example, if I have two 24V 100AH EG4-LL batteries connected in series, the
output voltage will be increased to 48V. In this example, the total capacity of the system remains
at 100AH, but that capacity will be delivered at a higher voltage.
How do you wire your batteries in series?
Note: EG-4 Batteries are capable of being connected in series up to 48v. DO NOT exceed a 48v
setup or you may severely damage your batteries and may void the warranty.
When you wire
your batteries in series, ALL BATTERIES SHOULD BE AT THE SAME STATE OF CHARGE
PRIOR TO CONNECTING. Please take a moment to charge your batteries with a proper
lithium charger to ensure they are at the same voltage.
1. Identify the positive and negative terminals on your batteries. These are color coded
red
for positive (+)
,
and
black for negative (-)
for your convenience.
2. Make a proper connection to the negative terminal of your first battery. Ensure that you
have followed directions to properly connect the cable to the terminal. Improper
connections can cause severe damage and may void your warranty.
3. Connect the other end of your cable to the positive terminal of the other battery you are
connecting to. Ensure you have followed directions to properly connect the cable to the
terminal.
4. Repeat steps 2-3 for additional batteries, but ensure that you
DO NOT
exceed 48V.
5. From the positive terminal of one battery on the end of the string of batteries, connect
your cable leading from your battery's positive side to the rest of your system.
6. From the negative terminal on the battery at the
opposite end of your battery string
,
connect your cable leading from your battery's negative side to the rest of your system.
