Lifos 72Ah FAQ
What can I power from the 72Ah battery?
Lifos can power a device just the same as a lead acid 12V battery can. The maximum drain of power from the battery is 80A and the maximum charging rate is 40A.
Is there a Bluetooth device inside this battery?
Yes, the BMS (battery management system) uses Bluetooth and an app to let you see what's going on in the battery.
What is considered to be a “battery cycle”?
A full battery cycle is a 100% charged battery going to 10% charged and back again to 100% charged. This Lifos 72Ah should let you complete more than 2750 of these cycles in its lifetime. If you only use the battery to 50% discharge (1/2 a cycle) then you could possibly get 5000+ cycles in this battery’s lifetime.
How many cycles should I expect to get form this battery?
Depending on the depth of discharge you should see over 2750 + cycles in your battery’s workable life.
Can you prove the battery can achieve the said cycles, or is it based on what could be?
Yes, we test our batteries with an accelerated charging cycle this is done 2000+ times (eight cycles a day) and takes over 250 days of cycle testing.
What connections are on the Lifos 72Ah battery?
We have a choice of connections on the Lifos 72A h battery
Quick release compatible terminals.
Top connections M8 bolt, spring washer and washer included.
Low profile connections M8 bolt spring washer and washer included.
How long should it take to charge this battery?
This is very dependent on the charger you are using but to give you some idea a 20A mains charger would charge this battery in around 3.5 hours (20A x 3.5h =70Ah).
Can I put this battery into a battery bank?
Yes, but a limited one. You can connect two in series, giving you a 24V battery bank or two in parallel giving you a 144Ah capacity battery bank.
How many batteries can I make into a battery bank?
This battery is limited to a maximum battery bank of 24V (i.e. two connected in series)
It will not work at higher voltages.
Will this battery work on a 24V or higher system?
This battery is limited to a maximum battery bank of 24V (i.e. two connected in series)
It will not work at higher voltages.
Can I mix Lifos batteries in a battery bank with other sized Lifos units?
No this is not supported.
I have an old Lifos 72Ah and want to add a new one in a battery bank is this ok?
While you can do this, the newer battery will only work as well as the older battery in the bank. We do not recommend this unless prior approval is gained from one of our technical team.
Can I mix chemistries in a battery bank?
No this is not supported.
Do I need a special charger for this battery?
No, you don’t as long as you only use around 90% of the capacity it will charge from most standard lead acid battery chargers. If you run this battery flat, then you would need a charger that presents voltage to the terminals even though there is no voltage at the terminals.
My battery has been run down to 0V how can I get this working again?
You need a charger that presents voltage to the terminals even though there is no voltage at the terminals. We have a 3A unit available on our web site HERE. Once your battery has 2 or 3 % charge back in it you will be able to use most lead acid chargers.
How can I get the app for this battery?
Depending on the phone / tablet you have you will need to visit the Apple app store or the Google play store. Search for Lifos, or click on the links at the top of this page. It’s a free download.
What information will the app give me?
The app will let you see:
Voltage of the battery terminals.
SOC (state of charge) of the battery form 0 to 100%.
Power in watts either charging or discharging.
Power in amps either charging or discharging.
Temperature of the battery.
My Lifos app won’t connect to the battery, what can I do?
There are two different steps to try and help fix this for you –
Step 1 - Make sure that “location services” are enabled on your phone.
Firstly, completely close the Lifos app.
Specific guidance on how to check location services on your device will be available in your device’s user manual, but we have provided links for the basic instructions for each platform below –
o iOS - https://support.apple.com/en-gb/HT207092
o Android - https://support.google.com/accounts/answer/3467281?hl=en
Once you have confirmed that location services are definitely enabled and there are no restrictions for the Lifos app, you can close that function on your device.
Now reopen the Lifos app and try to reconnect to your Lifos battery.
If this hasn’t resolved the issue, proceed to step 2.
Step 2 – Uninstall and then reinstall the Lifos app
Uninstall the Lifos app.
Specific guidance on how to do this on your device will be available in your device’s user manual, but we have provided links for the basic instructions for each platform below –
o iOS - https://support.apple.com/en-gb/101550
o Android - https://support.google.com/android/answer/13627402?hl=en-GB
You can now download and re-install the app from the relevant platform store, and the links for these shown towards the top of this page.
Now reopen the Lifos app and try to reconnect to your Lifos battery.
If these two steps don't resolve the issue, please contact technical support by emailing support@solartechnology.co.uk, or phone 01684 774000 for further guidance.
