Always put on insulating gloves when connecting/operating battery to application.

WHAT’S IN THE BOX

BEFORE CONNECTING

READ THIS MANUAL IN ITS ENTIRETY BEFORE OPERATING THE UNIT.
Remove the insulating plugs on the battery.
Fully screw in the MS bolts on to the terminals.
Put on the insulating covers as needed to avoid metal objects to short circuiting the terminals.
The terminals are ready for use.

BATTERY SPECIFICATIONS

Nominal Voltage:	12.8V
Nominal Capacity:	100Ah
Internal Resistance:	<50 mo

STATE OF CHARGE (SOC)
This battery’s capacity (or state of charge) can be roughly estimated by its resting voltage. Please refer to the following chart for percentages and their corresponding voltages.

RESTING VOLTAGE
Resting voltage of Lithium Iron Phosphate (LiFePO4) batteries reflects more accurate state of charge than its voltage during charging or discharging. To measure the resting voltage, disconnect the battery from the application or charger, and let the battery rest without loading for 30 minutes. Then you can use a multimeter to measure the voltage by connecting the probes to the battery terminals.

CAUTION: If you plan to connect multiple batteries together in series or parallel, please note that it is extremely important to ensure all batteries are charged to the same resting voltage before connecting. Connecting batteries without charging them to the same resting voltage may result in permanent damage.

CONNECTING MULTIPLE BATTERIES IN SERIES/ PARALLEL

It is possible to connect multiple identical batteries in pairs to better match your power requirements. You can connect batteries in series to increase voltage or in parallel to increase total capacity. You can connect up to 4 Tenergy 12.8V 100Ah together. See connection examples below.

To Connect in Series: (Shown as 51.2V 1 00Ah Battery Pack)
To Connect in Parallel: {Shown as 12.8V 400Ah Battery Pack)
To Connect in Parallel & Series (Shown as 25.6V 200Ah Battery Pack)

CAUTION: Before connecting batteries, make sure to charge the batteries to the same resting voltage. Connecting batteries without charging them to the same resting voltage may result in permanent damage.

Use the following tips if you plan to connect multiple cells in series/ parallel.

Only use identical batteries purchased at the same time to make connection.
Do not connect more than 4 Tenergy 12.BV 100Ah batteries together.
Do not mix new and old batteries for connections.
Choose proper cable or copper bar for battery connection. Refer to a licensed technician on the choice of cable and wire gauge.
Balance before connecting the batteries by bringing all batteries to the same resting voltage or within 0.1V difference before making the connection.
Rebalance your batteries independently every 6 months to ensure all batteries in connection are at the exact same voltage.
Always wear insulating gloves when connecting batteries.

STORAGE AND MAINTENANCE

For long term storage, place the battery in a dry and ventilated room at temperature between 0°C to 30°C (or 32° F to 86° F)
The best storage voltage for this battery is 13.2V. To prolong battery life, charge the battery back to 13.2V every 6 month to avoid over discharge when not in use.
Do not store battery near corrosive material, fire, or heat sources.

FREQUENTLY ASKED QUESTIONS

Q: What can this battery power?
A: This battery can be used for auxiliary power in RV’s trailers, motor homes, boats, cabins, sheds, gazebos, dump trailers, and where you need stored energy. (Note: This battery is not designed for starting vehicles.)
Q: What does DOD mean?
A: DOD stands for depth of discharge, it refers to when the output of energy in the battery stops. For example, if you used one third of the energy, the DOD is 33%, if you used half of the energy, the DOD is 50%.
Q: What is the charge setting I should use for this battery?
A: We recommend to charge this battery through charger/inverter that comes with dedicated LiFePO4 (Lithium Iron Phosphate) charging mode. For LiFePO4 chargers, choose preset of 4S (or 12.BV) for charging voltage and 20A current for charging current.
Q: Can I use lead acid charger/charging mode to charge this LiFeP04 battery?
A: Yes you can, but only limited to programmable lead acid charger. Please use following setting on programmable lead acid charger if LiFePO4 charging mode is not available:
Q: Does this battery come with built-in protection circuit module (PCM)?
A: Yes, this battery comes with built-in PCM with following protective features: overcharge
voltage/current, over discharge voltage/current, short circuit, over temperature and under temperature. Each of these protective features has their own triggering point and will stop the battery from operating once an issue is detected.
Q: I tried everything but it’s still not working or not meeting my needs.
A: Please contact our customer service team for further assistance.
