LIFOS GO 72Ah Lithium Iron Phosphate Battery User Manual

LIFOS GO 72Ah Lithium Iron Phosphate Battery

Introduction

This guide should be read in conjunction with the main instructions included overleaf, but the following points will enable speedy deployment of your Lifos Go 72Ah battery.

1. Your Lifos Go 72Ah will be supplied partially charged. This is because transportation regulations prohibit shipping a fully charged lithium battery. Please ensure the battery is fully charged before first use.

2. Please ensure you depress the On/Off button before its first charge. It will be clear the battery is active because the indicator will glow green. If you intend to deactivate the battery or leave it for long periods without using it, please press the button again to turn it off. This process helps prevent natural power loss and will keep your battery in top condition. Note, if the power button is in the On position but has not had any charge or discharge for a period of 12hrs the indicator light will turn off. This confirms the battery is in a dormant state to conserve energy but will instantly switch back on again once a load or charge is recognised.

3. Lifos Go 72Ah can be charged by a solar panel (via a suitable charge controller), vehicle alternator (via a suitable DC to DC converter) and any lead acid or lithium iron phosphate battery charger.
   In general, any charger with a voltage range of 11.2v to 14.7v will charge Lifos, however, be aware that some chargers that do not reach 14.7v may not 100% fully charge your Lifos battery. Do not use chargers with an upper cut- off voltage higher than 14.7V i.e. those for designed for NMC / LCO lithium chemistry. If in doubt, please contact hello@lifos.co.uk

4. The Battery Management System (BMS) within each Lifos Go 72Ah battery may give inaccurate data via the Bluetooth App until ten charge and discharge cycles have taken place. This is because during these ten cycles the BMS is balancing and calibrating the four lithium cells within Lifos Go 72Ah.

5. If more than one Lifos Go 72Ah has been purchased and you wish to connect them in series, parallel or both please see page 1 of this manual for detailed instructions.

6. Always use an appropriate sized cable and fuse based upon the expected current of your load. This ensures the electrical circuits within the load and the battery are protected at all times. Fit the fuse/s as close to the Lifos Go + terminal as possible. If in doubt consult a qualified electrician or contact Lifos – hello@lifos.co.uk (or its retailers / agents) for advice.

Tips

A few tips on how to get the best from your Lifos Go 72Ah battery:

• Protect the battery from direct sunlight although it will work well in a wide temperature range (-20 to +60 degrees C).

• Lifos Go 72Ah has an IP rating of 54. This means that water splashes from all directions, such as light rain, and dust ingress will not damage the battery.
  This does not mean the battery is waterproof and should be protected from the elements particularly if permanently used outdoors.

• Observe the correct polarity otherwise permanent damage could be caused – the battery casing is marked with + and –.

• Don’t short circuit Lifos Go 72Ah otherwise permanent damage could be caused.

• Lifos Go 72Ah can be connected in Parallel (Fig.1). You are able to connect up to 4 Lifos Go 72Ah batteries in parallel giving you a battery bank capacity of 288Ah (72A x 4).

• Lifos Go 72Ah can be connected in Series (Fig.2). You are able to connect up to 4 Lifos Go 72Ah batteries in series giving you a battery bank voltages of 12v (single battery), 24v (2 x batteries) 36v (3 x batteries) or 48v (4 x batteries).

• Lifos Go only generates limited heat and no noxious gases.

The Lifos Go 72Ah can be connected up in parallel or series when needed but only in the below configurations:

Parallel

|

Series

---|---
|

1 (12v)

| 2 (24v)| 3 (36v)|

4 (48v)

1

| YES| YES| YES| YES
2| YES| YES| YES|

YES

3

| YES| YES| NO| NO
4| YES| YES| NO| NO

Please note – when connecting multiple batteries, fully charge each battery and allow at least 6 hours to ‘settle’ and then check each is within 50mV of each other.

Once all are within this tolerance they may be connected to one another.

• Most mains lead acid battery chargers will charge the Lifos Go 72Ah but some smart chargers might only charge up to 85%. If this is the case we recommend getting a new charger, please see our website for recommendations on the FAQ pages. However you will not cause any damage to the battery if using your old charger.
  For DC – DC charging please also check our website for recommendations on the FAQ pages.

• Lifos Go 72Ah can be used if it is positioned on its side but will give best performance if it is positioned with its terminals facing upward.

NOTE – do not mix new Lifos Go 72Ah batteries with old batteries, whether in series or parallel.

Storage of Lifos Go 72Ah

Lifos Go 72Ah has an extremely low rate of self-discharge but if you intend not to use the battery for an extended period please charge the battery to approx. 80% and turn the power button off prior to storage. It is recommended to re-charge the Lifos Go 72Ah once every 3 months.
NOTE – allowing the battery to over discharge (+3 months since its last charge) can lead to a shortened life, could damage the battery and invalidate your warranty.

Accessing the Lifos App

The App is available for all Apple and Android devices. Search the Apple App store for Lifos and down load for free. If using an Android device go to Google Play search Lifos and down load for free. The App will give you full visibility of your Lifos Go 72Ah battery and its performance. Your device connects to the Lifos App via Bluetooth so you need to be within 10m of the battery to access its data. Each time you wish to view the data you will need to log on via the App but this is quick and easy.

If you are using more than one Lifos Go 72Ah battery, you will not be able to identify each battery separately if they are in close proximity to one another.

If you have connected your batteries in parallel then you only need to look at any one battery (it does not matter which one) to see the total power for the complete battery bank (SOC).

If you have connected your batteries in series then you also only need to look at one battery to see the total power for the complete battery bank, however you will only see the voltage of the battery bank from the single battery and not the battery bank as a whole.
If you have any questions about this connectivity please visit www.lifos.co.uk for help.

NOTE – only one Apple/Android device at a time can be connected to each battery

Lifos Go 72Ah battery load limitation

The Lifos Go 72Ah battery is perfectly suited to heavy DC loads such as motor movers, but its Battery Management System (BMS) will not allow any load higher than 150A or 1875w at 12.5vDC or 1500w at 230vAC through an inverter. It should be noted that inductive loads, even if rated at 1875w may not be powered by the Lifos Go 72Ah because the inrush current of these devices can often be many times the rated load during initial start up. Examples of inductive loads are microwave ovens.

Resistive AC loads (via a suitable 12vDC to 230AC inverter) that can be powered by Lifos Go 72Ah include: toasters, travel kettles, travel irons, hair dryers, heaters etc (Max 1500W).

NOTE – in the event an AC load higher than 1500w is connected to Lifos Go 72Ah the battery will shut down and will not power the device but the battery will not be damaged because its BMS will protect it. In this circumstance the Lifos Go 72Ah will be instantly reset so it is able to power loads within its approved power range as noted above.

Connecting up your Lifos Go 72Ah battery

When connecting to the Lifos Go 72Ah using the bolts and washers provided, we recommend a torque setting of 8Nm.

Please connect the Positive (+) connection first before connecting the Negative (–) connection.

In all circumstances, an appropriate sized fuse must be fitted to all positive cables being connected to the + terminals of Lifos Go 72Ah as failure to do so could result in damage to either load circuit or Lifos battery in the event of an accidental dead short etc. Please consult a qualified electrician if guidance is needed regarding fuse or cable size appropriate to your load.

Disconnection is the reverse process, Negative (–) first, Positive (+) last. (This is standard disconnection procedure for connection and disconnection of batteries and will help to avoid short circuits).

Disposal

Disposal of a used or damaged Lifos Go 72Ah battery must be done at a certified recycling location. There are many of these nationwide – please see www.lifos.co.uk for details.
