Eco Battery Gen2 batteries are only compatible with Gen2 SOC meters.
BATTERY VOLTAGE
The voltage will vary based on the current load or charge placed on the battery.
STATE OF CHARGE (SOC)
The state of charge is displayed in percent. 0% = empty and 100% full.
BATTERY CURRENT
Discharge current (in amps) is diaplayed as a negative number.
Charging current (in amps) is displayed as a positive number.
METER CALIBRATION
The Eco Battery SOC meter does not require calibration by the end user. The SOC meter performs a
self-calibration at the end of each full charge cycle. Accuracy is +/- 5%.
Due to lithium’s at voltage curve, SOC % is the most accurate method for monitoring a lithium batteries
state of charge. Please monitor the SOC % rather than battery voltage when determining when to charge.
Avoid running the battery completely dead. Although the BMS protects against detrimental discharge,
it is not advised to run your battery below 20%. When driving your cart, be aware of your state of charge,
just as you would monitor your vehicle's fuel gauge. The further you are from a charging location, the
more battery you should reserve.
Your meter may be programmed with a sleep timer that will darken the meter after a few hours of inactivity.
To wake the meter, the battery needs to see current in or out of it. Driving your cart a few feet or connecting
the charger, or cycling the power button will awaken the meter.
Some Gen2 gauges are programmed to display DTCs (Diagnostic Trouble Codes)
if a battery fault has been detected. These faults can vary in severity depending
on the situation. SEE PAGE 7 FOR TROUBLE CODES.
If a trouble code appears on your meter, please record the trouble
code and contact your dealer to discuss the code and, if necessary,
take any actions required to correct it.

The two connectors located on your meter cable are CAN
communication ports used for diagnostics, or communicating
with a charger or motor controller.
Some battery chargers are CAN enabled, and will have a male
CAN plug to connect to either one of the two CAN ports. If your charger
is CAN enabled, the charger will NOT charge unless CAN is connected.
If your motor controller is CAN enabled and compatible with the Eco Battery CAN protocol, connect the CAN
connector from the controller into either of the CAN ports on the meter cable.
The power button controls ow of power in and out of the battery.
It functions as a safety device to allow for safe handling of
the battery during installation and maintenance. It also serves
as a way to completely disconnect the battery during storage
to prevent unnecessary discharge over extended periods.
To power on the battery, press and release the power button until the green light illuminates.
To power o the battery, press and release the power button until the green light turns o.
If the battery is not charged or driven for an extended period of time, the battery will automatically
power o to conserve power. (See POWER SAVE MODE pg. 5 )
The power button does not need to be turned o with each use. It is recommended to leave
the power button on and the battery charger connected if the cart will be used within 15 days.
If the cart will be unused for longer than 30 days, fully charge the battery, disconnect the charger
AC power cord, and turn the battery o.
The power button MUST be turned on to charge or discharge the battery.

BATTERY CHARGER
Use only genuine Eco Battery lithium chargers, or a lithium
charger specically approved by Eco Battery. This will ensure
optimal charging and will extend the batteries service life.
DO NOT USE UNAPPROVED BATTERY CHARGERS OR TENDERS.
DO NOT CONNECT DC OUTPUT CABLES TO BATTERY WITH REVERSE POLARITY.
Doing so will cause irreversible damage and is not covered under warranty.
CHARGING INSTRUCTIONS
1. Connect the DC output ring terminals to the battery terminals.
2. Connect AC input to AC power.
3. Charger LED will will blink red when charging and will be steady green when complete.
Battery must be powered on with the power button illuminated to accept a charge.
Note: If your charger utilizes CAN charging, you will need to connect the CAN connector
from the charger into either of the two CAN ports on the meter cable.
CHARGE TIME
The charge time can be calculated by the formula below:
Ah capacity of Battery / Charging Amps of Charger
Example : 105Ah battery / 15A charger = 7 hours
(assuming the battery is fully depleted)
The Eco Battery charger is not a oat charger or battery maintainer, and will not hold the battery at 100%
after a charge. If left plugged in, the battery battery must drop below a pre-set voltage before a new charge
cycle can begin. It is normal for the state of charge to drop as low as 70-80% before the charger begins a new
cycle, but it will not allow the battery to be completely discharged while plugged in.
It is a common misconception that lithium batteries develop a “memory” while charging and that they
need to be completely discharged and charged with each use. This is not the case with Eco Battery lithium
batteries. Charging every night will not harm the battery and will ensure that you are always topped o
and ready for your next adventure. Topping o or partially charging to extend range is perfectly acceptable.
Recommended extension cord lengths:
Up to 15’ = 12 -14 AWG
10 to 25’ = 10 -12 AWG
>25’ = not recommended
All Eco Battery chargers are capable of accepting AC input of 100 - 250 VAC, single phase, 50 or 60 htz

POWER SAVE MODE
If your battery was built after 08/01/2022 (or has updated rmware) it will be programmed to enter
Power Save Mode after extended periods of inactivity. Power Save Mode will ensure that your battery
will not be fully depleted in the event that your cart sits for an extended time. The time that must elapse
before Power Save Mode will be activated, is dependent on SOC (see below). When Power Save is active,
the battery will be completely powered o (no charge or discharge) and the meter will turn o.
SOC = 21% - 100%
The battery power and gauge will power o after 7 days of inactivity.
SOC = <20%
The battery power and gauge will power o after 24 hours of inactivity.
When in Power Save Mode, the green LED on the power button will not be illuminated, even if the
power button is in the on position. To wake the battery from Power Save Mode, turn the battery’s
power button o, then back on.
If your battery has gone to sleep on its own, we suggest fully charging it before using it again.
It is always good practice to turn the key o to your golf cart when not in use.
For long term storage, fully charge the battery, unplug the AC power source to the charger,
and turn o the power button.
After long term storage, it is advised to fully charge the battery before use, regardless of SOC displayed.
During long term storage, the calibrated SOC may drift, and must be fully charged to re-calibrate.
The battery must be charged at least once every 6 months. Failure to charge for 6 months may
permanently damage the lithium cells, and is not covered under warranty.
If your golf cart will be stored below -20°F, remove the battery from the cart and store in ambient
temperature above -20°F. Also, keep in mind, while the battery will still function between -20°f and 32°f, the
battery will not take a charge below 32°f. (See Cold Weather pg 6)
DO NOT USE THIRD PARTY BATTERY TENDERS.

CLEANING
COLD WEATHER
Be mindful that there are sensitive electronics in your battery when cleaning your golf cart.
Although your lithium battery is well sealed, DO NOT CLEAN BY PRESSURE WASHING.
Pressure washing can lead to premature damage to the lid seal of the battery , and is not
covered under the warranty policy.
The recommended procedure for cleaning your battery is blowing o
with a leaf blower, or wiping it o with a clean damp cloth.
NEVER USE CHEMICALS OF ANY SORT TO CLEAN YOUR BATTERY.
Your battery is equipped with a temperature sensor that will shut it down in
temperatures below -20°f. This feature protects the battery from cell damage
caused by excessively low operating temperatures.
While your battery will discharge down to -20°F , it will not accept any type of
charge below 32°F. This includes plug in charging as well as regenerative charging
from your carts motor controller.
It is not recommend to drive a golf cart equipped with regenerative charging/braking systems when
the overnight low temperature is under 32°F. Doing so may cause the battery to enter self-protection
mode and can lead to braking system faults on certain carts.
It is important to note that the above temperatures are in reference to the core battery temperature
and not the ambient air temperature. Your actual core battery temperature could be drastically
dierent from the ambient air temperature as the battery will increase and decrease in temperature
at a much slower rate than ambient air temperature.
As with all batteries, you may notice a decrease in performance and range in colder temperatures.
This is normal and expected. Some decreases in performance may include shorter run times, slightly
slower acceleration, and larger than normal voltage drops.
