No special charger is required.  Any normal lead-acid battery charger designed to output a Constant Voltage Constant Current (CCCV) charge profile, which 95% of chargers do, then this is fine and safe for LithiumPro batteries. Many battery chargers will have pre-programmed settings for different battery chemistries.  For Lithium batteries, select the ‘LiFePO4’ or ‘LI-ion’ profile. If your charger doesnt have a Lithium profile then select the closest charge profile between 14.2-14.6v. 

Of course, should you wish to upgrade you old charger to a lithium based charger, we would recommend this, as it will charge faster and more efficiently, whilst offering more enhanced protection features during charging, thus preserving the life of you battery.

You can charge your Lithium battery using any or all of the three simple ways listed below:-

1.  Harness your alternator’s surplus power to deliver a steady 14.4v charge voltage. Click here for DC-DC Chargers

2. Using a MPPT Solar Charge Controller, you can charge your leisure batteries at a regulated voltage using your solar panels ability to harness the suns energy. Click here for Solar Charge Controllers

3 Using a Mains hook-up charger, you can use a domestic 240v electricity supply to charge you leisure batteries via hook-up or shore power. Click here for Mains Chargers

IMPORTANT: When you first receive your battery, fully charge it until you get a ‘Cell Over Voltage’ (COV) notification. This indicates the battery is fully charged. Then, complete a full discharge until you get a ‘Cell Under Voltage’ (CUV) notification, showing the battery is fully discharged.This process allows your Battery Management System (BMS) to calibrate the State of Charge (SOC) in your app. The BMS will then learn to provide more accurate data, understanding both the 0% and 100% charge parameters.

It is recommended to charge your battery at ≤0.5C (0.5 times the battery’s rated capacity). For instance, if the battery has a capacity of 100Ah, the recommended charging current would be ≤50 amps. Please observe the maximum charging capacity listed on your battery.

Your Lithium Battery with a Constant Current Constant Voltage charger CCCV with a LiFePO4 charging profile.

Absorption should be set to 14.2-14.6v (14.4v Optimal)

Float should be set to 13.5-13.9v

De-sulfation/Equalisation should be switched off

Most Victron chargers already have a Lithium charging profile. However, should you wish to personalise your settings, please use the following;

Absorption voltage: 14.4V
Absorption time: Recommended setting is half an hour per 100ah of LiFePO4 battery (for example if you have 2x 150ah batteries select 90mins).
Float Voltage: 13.5V
Equalisation voltage: This must be disabled on all Lithium batteries as this can damage the battery with pulses of high voltages. This is designed for lead acid batteries to add with desulfation.
Temperature compensation: This should also be disabled on Lithium batteries.
Charged Voltage: This is where your battery is considered fully charged – Lithium batteries should be set to 14.4V for Victron equipment.
Low Temperature cut-off: All Lithium Pro Batteries have low temperature charging protection built into the BMS. SMARTCOMM SERIES batteries all have cell heating technology so this function needs to be disabled.
Discharge Floor: 0%
Tail Current: This is the minimum current at which the Smart Shunt considers charging or discharging finished. We recommend 4%.
Peukert Exponent: Not required – this is for Lead Acid batteries.

SMARTCOMM BATTERY PROFILE (HEATERS)
ULTRAVOLT (NO-HEATER)

Yes our ULTRAVOLT and ARCTICXTREME batteries are all ‘Drop-In’ Lead-Acid replacements. They are exactly the same size and shape as your old Lead-Acid batteries with the exact same terminal posts, so there is not need to change your electrical connections. They even have the base rail at the base to safely secure your battery in place. No need to look for inventive ways to strap Chinese replacement batteries down. Click here for ‘Drop-In’ replacement batteries.

Yes, all LithiumPro Energy batteries can be connected in Series or Parallel to increase the voltage or capacity respectively.

Our SMARTIQ BMS APP with also be able to display your battery system parameters as a whole in both Series or Parallel configurations.

WARNING: Never connect Lithium batteries of different brands, capacities, or ages together. All brands have unique Battery Management Systems (BMS), and mixing can cause imbalances in charging or discharging, potentially leading to overheating and premature failure. NOTE: Always fully charge each battery separately before connecting them in series or parallel. LithiumPro batteries can be configured as follows:

• In series to increase voltage up to 24V, 36V, or a maximum of 48V.
• In parallel up to a maximum of 4 batteries for the SMARTIQ SERIES. Or a maximum of 8 batteries for SMARTCOMM SERIES.

For series configuration, ensure each battery is charged to within 0.05V of each other to prevent imbalances.

For parallel configurations, use cables that are as short and identical in length as possible; batteries naturally equalise in voltage when connected this way.

LiFePO4 chemistry is the most stable and reliable of all lithium technologies.  If cared for correctly and used according to the manufacturers guidelines you should still be using your Lithium Pro battery in 10+ years time. LithiumPro Energy only use traceable Grade-A Prismatic cell technology in all of their batteries which are capable of over 4000-8000 cycles at 80% depth of discharge. Meaning if used every day it will last between 11 -21 years, and still retain 80% of their rated capacity. We are so confident of all our batteries they are covered by our comprehensive 5 year manufacturers warranty.

Yes, you can safely discharge your Lithium Battery down to temperatures as low as -20ºc However, in general Lithium batteries cannot be charged in temperatures below zero unless they have cell heaters embedded within the battery. All LithiumPro Batteries have a safety feature built into the battery to prevent it charging below 0ºc if they do not have cell heating technology. If you are using one of our SMARTCOMM SERIES batteries they are come with cell heaters built-in  as standard Click here to see our ARCTICXTREME V2 Battery designed for charging in colder climates.

When connecting batteries together for communication via CANbus ports, use standard RJ45 cable to link them and terminate last battery with the RJ45 termination plug provided. See diagram here.

If you wish to connect your SMARTCOMM SERIES batteries to Victron GX, Cerbo or the Ekrano you will need to purchase a SMARTCOMM SERIES Cable.

LithiumPro SMARTCOMM SERIES batteries offer full Plug & Play integration with Victron via CANbus

CLICK HERE for more information how to connect your Victron equipment to LithiumPro batteries

The RJ45 termination adapter included with your battery is for when you are using CANbus to connect you batteries together in parallel. It enables the BMS in each battery to communicate with one another and to Victron equipment. If you are not using CANbus integration then this is not required, but do keep it safe for the possible future integration.

This switch is for optionally disabling and enabling the charging MOSFETS of the  BMS remotely. This cable only works with V2 of the ARCTICXTREME.

When connected to RJ45 Port 1 and the switch is depressed this will disable all charging and discharging sources from the battery. You can use this when carrying out maintenance or just wish to stop all loads from consuming battery power.  You will still be able to monitor the State of Charge , SOC, of your battery as the BMS will still be active. 
If you wish to put your battery into long term storage 3-6 months we suggest using the BMS isolation switch at the top edge of the battery. This will also prevent all loads from draining the battery but will also shut the BMS down thus reducing power consumption to a minimum whilst in storage. Note: your app will not function in this state.  The battery should be charged to 65-70% before isolating ready for storage.

With the newer version of the ARCTICXTREME & SEATBASE batteries we have included a longer Remote Power ON/OFF cable. This also switches of the power to the battery for putting it into hibernation.  The power button is designed to be panel mounted for ease of access when isolating your battery for storage or maintenance.

The POWER button is for switching ON/OFF your battery.

When shipping your battery for the first time it will be shipped in ‘hibernation’ mode for safety.  You will need to switch the battery on to start charging the battery.

The isolation button can be used to put your battery into long term storage 3-6 months.  This will also prevent all loads from draining the battery but will also shut the BMS down thus reducing power consumption to a minimum whilst in storage. Note: your app will not function in this state.  The battery should be charged to 65-70% before isolating and putting into storage.

Do not leave battery at 100% State of Charge in storage, this can reduce the lifespan of the battery.
