Section 1 - Quick Start Guide
Cable Conversion Guide
Step 1. 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 Gauge 2 (35mm²)
2000W Inverter - at least Guage 00 (70mm²)
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.
Step 2. Your charger/s need to be programmed for Lithium, with a charging voltage of 14.0 -14.6 Volts
and Float 13.5 - 13.6 Volts.
Do not use a lead-acid charger if you want the best out of your battery. These chargers can damage the
battery if left connected and will void your warranty.
Step 3. Fully charge the battery and it is ready for use.
*Note: The above is a“Quick Start” guide, detailed information follows.
Page 4 Enerdrive B-TEC G2 Manual (Rev. 2.1)

Section 2 - Charging
Lithium batteries need to be charged slightly differently to other batteries.
To ensure they live a long life and provide maximum capacity, you must use a charger with a lithium
setting - this includes:
AC Chargers
DC to DC Chargers
Solar Controllers
If your charger allows, set the charge voltage from 14.0 -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 for the 100Ah & 125Ah batteries should be 40 Amps or less,
and for the 200Ah battery, 60 Amps or less. You can charge at higher currents, but the recomended 60
Amps or less is recommended. See Section 9 - 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. Enerdrive recommends the use of a Lithium
profiled charger that meets the batteries voltage specifications.
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 possible damage to the Lithium BMS system. The battery is not covered by warranty
if installed in this manner.
www.enerdrive.com.au Page 5

Section 3 - Discharging (using the battery)
The Enerdrive B-TEC Lithium Battery can deliver a maximum of 100 Amps for the 100 & 125Ah battery and
200 Amps for the 200Ah battery for 30 minutes due to the high power, high quality Battery Management
System (BMS) and prismatic Lithium cells inside the battery. For this to happen, you MUST USE cable of the
correct guage.
These are recommended wire guages and approximate current specifications for cable lengths shorter
than 1-2 meters:
Guage 2 35mm² 100 Amps
Guage 0 50mm² 150 Amps
Guage 00 70mm² 200 Amps
A 2000W inverter will draw approximately 170-180 Amps through the cables connected between it and the
battery - this will NOT be achieved with undersized wire.
Consider current like plumbing...
The thicker the pipe (cable) the more current can flow through it.
Page 6 Enerdrive B-TEC G2 Manual (Rev. 2.1)

Section 4 - 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 Battery Fully 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 5 - Restarting Your Battery.
www.enerdrive.com.au Page 7

Section 5 - Restarting Your Battery
We strongly recommend keeping the battery charged to avoid activating the internal low battery
voltage disconnect.
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 on top of the battery for 5-10 seconds
4. Release and wait 7 seconds
5. Power should now be restored and charging will commence
6. When the SOC (State of Charge) is above 20%, loads can be switched on if required
By continuously tripping the low voltage disconnect 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.

Section 6 - Using the Smart Phone Battery Monitor
The Enerdrive B-TEC Lithium Battery incorporates a Smart Phone Monitoring system. By downloading
the Android™ or Apple® app to your smart phone or tablet, you can monitor the following information:
Battery Capacity Individual Cell Voltage
Battery Voltage Battery Temperature
Battery Current (Amps) Battery Cycles
Battery State of Charge (SOC) Battery Alarms
Battery State of Health (SOH) Battery Event Information
Battery Status
* Red light is only an indicator, not a fault condition.
* The default password is 1234 (this allows you to change the Bluetooth name of the battery).
* A notification will only appear in the notifications page if under alarm condition.
www.enerdrive.com.au Page 9

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. Enerdrive Pty Ltd is not responsible
for any accidents cause by the usage without following our specification.
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) the battery will disconnect.
Section 7 - Warnings
Page 10 Enerdrive B-TEC G2 Manual (Rev. 2.1)

Section 8 - 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 the 100 & 125Ah batteries this is 100
Amps and for the 200Ah battery, 200 Amps. 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, ensure they are fully charged, 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.
Battery Monitor Shunt
(if installed)
Battery Positive & Negative Link Cable
must be equal lengths
Main Fuse
Main Negative Cable
Main Positive Cable
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.
Ultimately for larger AH systems, the best solution is to use the Enerdrive“Pro Series”battery system -
see our website or contact us for details.
www.enerdrive.com.au Page 11

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: Of course! We recommend an inverter size of 1000 watts maximum for the 100 &125Ah batteries
and 2000 watts maximum for the 200Ah battery.
Q: Can I install the B-TEC battery in a wet area?
A: It is not recommended - the best environment is a dry, cool, well ventilated area.
Q: Can I install the B-TEC battery on its side or end?
A: No.
