Section 1 – Installation

Your B-TEC battery must be installed in a dry and cool location.
Supplied battery trays and straps are the preferred mounting method. Ensure that sufficiently rated fasteners are used to hold the tray firmly to the mounting material.
Enerdrive highly recommend the battery is installed in the upright position.
Enerdrive approve installation of B-TEC batteries in accommodation areas of RV’s. Temperatures must not exceed the rated operating temperatures therefore natural, or fan forced ventilation maybe required.
There should be 25mm clear space around the B-TEC battery.
Consideration should be taken to not mount the battery near any metallic service lines such as LPG, diesel, or petrol lines. This is to ensure no accidental shorting of the battery terminals occur, especially when fitting or removing the battery.

B-TEC batteries must not be installed –

• In vehicle engine bays or in high heat environments, refer to Section 10 – Battery Specifications
• In wet areas such as caravan chassis mounts, open ute trays or boat deck areas.
• Inside compartments dedicated to carrying gas.

Section 2 – Connection

It is recommended that no more than four terminals be connected to a battery terminal, if you do have more than 4 terminals the use of a fuse block and negative busbar are recommended.
Cable terminal should be in the order with heaviest current draw (largest cable) in contact with the battery to light estimated current draw (smallest cable) terminals on the top.
Use of insulating terminal boots is recommended, especially in areas where accidental shorting may occur, such as storage lockers or under lounges and beds. Connect the Positive (Red) and Negative (Black) cables to the battery, ensuring you are using cable that is of adequate size for the demands of the system, and well crimped and protected termination lugs.

Example;
1000W Inverter – at least Guage 2 (35mm²)
2000W Inverter – at least Guage 00 (70mm²
3000W Inverter – at least Guage 000 (95mm²)

Cable Conversion Guide

The spring washers must be used on the battery terminal bolts – they apply pressure to the lugs for a secure connection. There is no need to over-tighten the bolts, simply ensure there is no movement of the cables. Make sure the main Battery Cable lug is mounted directly onto the Battery terminal with no washers between them.

Section 3 – Charging

Lithium batteries need to be charged slightly difierent to other batteries.
To ensure they live a long life and provide maximum capacity, you must use a charger with a lithium LiFeP04 setting – this includes:

• AC Chargers
• DC to DC Chargers
• Solar Controllers

If your charger allows, set the charge voltage from 14.2 – 14.6 Volts and Float 13.5 – 13.6 Volts and proceed with charging. We recommend charging at the lower end of the voltage scale for maximum longevity of the battery.
It is recommended that the charging current should be 30% of your battery capacity. You can charge at higher currents but 30% is the recommended for long life.
See Section 10 – Battery Specifications.

*Note:
You can charge a lithium battery with a non-lithium charger, but these chargers can deliver too much or too little voltage and may not cut off when the battery is full.
DO NOT use a charger with a “Pulse Stage” or “Equalisation Mode”. This will damage the battery and void warranty.
DO NOT connect this battery to a start battery with a VSR (Dual Battery System or “Voltage Sensitive Relay”).
The voltage of the Lithium battery may keep the VSR switched on resulting in it discharging into the start battery, and/or flattening the start battery.

Section 4 – Discharging (using the battery)

The Enerdrive B-TEC Lithium Battery can deliver a very high discharge current due to the high power, high quality Battery Management System (BMS) and prismatic Lithium cells inside the battery.
Refer to Section 10 – Battery Specifications for the maximum rated discharge current of your battery.
For this to happen, you MUST USE cable of the correct guage.

Inverter Usage
It is recommended to not put more load on your batteries than the rating of the BMS installed. We also recommend following the below even if you have two batteries in parallel, this protects overloading a single battery if the other battery in the bank was to shut down (i.e. low capacity).

• 12V 100AH B-TEC – 12V 1000W Inverter Max
• 12V 125AH B-TEC – 12V 1000W Inverter Max
• 12V 200AH B-TEC – 12V 2600W Inverter Max
• 12V 300AH B-TEC – 12V 3000W Inverter Max
• 24V 150AH B-TEC – 24V 3500W Inverter Max

Section 5 – Protecting Your Battery

Lithium batteries cannot be protected effectively by monitoring voltage due to their ability to maintain a higher voltage for much longer than AGM or flooded/sealed batteries.
“State of Charge” (SOC%) percentage is the most accurate and effective method of disconnecting loads from the battery – this requires a battery monitor which uses a “shunt” to measure the current going into (Charging) and coming out of (Discharging) the battery.

Example;
200 Amp BatteryFully Charged| State of Charge = 100%
---|---
50 Amps used| State of Charge = 75%
100 Amps used| State of Charge = 50%

It is recommended that Lithium batteries not be discharged below 20% State of Charge or the battery life may be shortened.
As an added layer of protection, the Enerdrive B-TEC Lithium Battery also has a built-in low voltage disconnect circuit. If this occurs, please refer to Section 6 – Restarting Your Battery.
If your battery has shut down due to low voltage you must charge your battery within 14 days to prevent permanent damage occuring to the cells.

Section 6 – Restarting Your Battery

Batteries with Reset Button on Battery
We strongly recommend keeping the battery charged to avoid activating the internal low battery voltage discconnect.
If your DC system shuts down, the battery may require re-starting. Please use the following procedure:

1. Turn off all DC and AC Loads
2. Connect charging source/s and switch ON
3. Hold the “Reset” button 5 seconds, release and quick press
4. Release and wait 7 seconds
5. Power will be restored and charging will commence after a few seconds
6. When the SOC (State of Charge) is above 20%, loads can be switched on if required

By continuously tripping the low voltage discconnect of the battery you may cause damage to sensitive electronic equipment that is attached to the battery. i.e. battery chargers, solar controllers, inverters, stereo equipment etc – all of which are not covered under the battery warranty.

Batteries without Reset Button on Battery
To reconnect, a charge voltage of ≥12.8v must be applied to the battery before the over-discharge release will activate and allow charge current to flow into the battery. This can be done via a momentary reset switch between the start battery and B-TEC or by jump starting with a portable power pack.
Follow the above steps to turn off all DC and AC loads, turn on charging sources and then activate reset switch or apply jump start pack, disconnect as soon as chargers begin charging.

Section 7 – Using the Smart Phone Battery Monitor App

The Enerdrive B-TEC Lithium Battery incorporates a wireless Smart Phone Monitoring system. By downloading the Android™ or Apple® app to your Smart Phone or tablet device, you can monitor the following information;

• Battery Capacity

• A notification will only appear in the notifications page if under alarm condition.

Section 8 – Warnings

Please read and follow the cautions listed on the battery before installation. Improper use may cause heat, fire, rupture, damage or capacity deterioration of the battery. Dometic Power & Control (Enerdrive) Pty Ltd is not responsible for any accidents cause by the usage without following our specification.

WARNING!
Failure to follow these instructions may result in early battery failure or possible personal injury.

• Do not use the battery for cranking/starting applications.
• Do not series connect the battery.
• Do not dispose of in fire.
• The battery must be installed far away from heat sources, high voltage, and avoid exposed sunlight for long periods of time.
• Do not throw the battery into water.
• Do not connect the positive and negative terminals of battery together.
• Do not ship or store battery together with metal.
• Do not disassemble the battery. Battery warranty will be voided if the case is opened.
• Do not drop, impact or puncture the battery.
• Do not allow the battery to sit in a discharged state511.50V
• When the battery capacity is low (515% SOC), please charge the battery.
• Please use the matched or suggested charger that contains a Lithium charge profile for this battery. Failure to install the correct battery charger will void all warranty.
• If the battery emits a peculiar smell, heating, distortion or appears to have any abnormality during operation or storage, please stop using the battery and take it out of service. Contact Enerdrive for further details
• If the battery leaks and gets into eyes or on skin, do not wipe. Rinse with clean water and seek medical attention immediately.

Low Battery Voltage Disconnect
The battery has a low voltage disconnect incorporated for self-protection. If the battery is drawn down to the internal low voltage disconnect set point 2.8v per cell (11.2V for 12V battery) the battery will disconnect.

Section 9 – FAQ

Q: Can I parallel B-TEC batteries?****

– A: The short answer is yes.
The long answer is – if you are drawing large currents, the maximum current delivered will be limited to the maximum instantaneous discharge capacity of one battery, for example; 200A on a 200Ah G2 B-TEC Battery.
With low to medium current draw installations (the vast majority of applications) you may never see an issue and your storage capacity will be greatly increased – I.E. 2 x 200 Amp = 400 Amp capacity.
When installing, fully charge the batteries separately – then let sit for 30 minutes before connecting together. When connecting in parallel – take the positive from Battery 1, and the negative from Battery 2 to your system as per the diagram below.
The Smart Phone App will only show the information from one battery at a time – not both. This is another advantage of a separate Battery Monitor – it will show the total system environment.
*Note: Slight variance of State of Charge or Amps may occur between the batteries in parallel however these should not vary by more than 5%.
It is recommend that annually the batteries be disconnected and individually charged allowing them to sit at a fully charged state for 12hrs each before connecting back together.

Q: Can I series connect B-TEC batteries to achieve higher voltage?****

– A: No. Enerdrive offers higher voltage Lithium solutions – contact us for details.

Q: Can I use an Inverter with my B-TEC battery?****

– A: Yes. Refer to Section 4 for more detail.

Q: Can I install the B-TEC battery in a wet area?****

– A: No. Due to the construction of the B-TEC cases the batteries must be installed in a dry environment to protect against moisture ingress.

Q: Can I install the B-TEC battery on its side or end?****

– A: No.
