How many RELiON lithium trolling motor batteries do I need?
With competitive price and timely delivery, Lithium Storage sincerely hope to be your supplier and partner.
It depends on your trolling motor voltage. RELiON offers 12-Volt and 24-Volt Lithium batteries. If you have a 12-Volt trolling motor then you can choose from several 12-Volt options. If you have a 24-Volt motor, you can use 2, 12-Volt batteries in series or a single 24-Volt battery. If you have a 36V trolling motor system, you can either go with pairing three 12V batteries in series, or getting a single 36V battery. RELiON has the perfect 36V trolling motor battery in the RB36V40.
Which RELiON 12-Volt battery should I use for my trolling motor?
RELiON offers several 12-Volt battery options to choose from. The most common models are; RB52, RB75, RB80 and RB100, which are 52Ah, 75Ah, 80Ah and 100Ah respectively. To get the same runtime as a wet or AGM lead-acid battery, use a lithium battery that is 60% the capacity of that lead-acid battery. If you want more time on the water, size up from there. Ex. 60Ah RELiON lithium battery = 100Ah lead-acid battery
Are RELiON lithium batteries a drop-in replacement to my lead-acid battery?
RELiON offers the standard size batteries; Group 24, Group 27 and Group 31.
Can I install my RELiON lithium batteries on their side?
Although they will operate on their side, we recommend installing them upright in marine applications.
What size cables should I use to connect my RELiON lithium batteries?
For most applications, we recommend either 4-AWG or 6-AWG cables.
Are my RELiON Lithium batteries waterproof?
RELiON lithium batteries are enclosed in an IP66 case, which means water projected from any direction will not be harmful. They will get damaged if they are submerged in water. We recommend you do your best to keep your batteries dry.
Do I need to use a lithium starter battery if my trolling motor batteries are lithium?
No, you can use a lead-acid starter battery with your lithium trolling motor batteries.
Do my RELiON lithium batteries have peak current limitations?
Yes, please refer to the data sheet to get the peak current limit for your particular model.
Does RELiON offer a lithium starter battery?
RELiON has an RB100-HP, which is a Group 31 dual-purpose battery that can be used for starting.
I have an RB100-HP for cranking and but it's not enough to run all of my electronics. Can I add an RB100 in parallel?
Yes, connecting them in parallel is fine. Although rare, we do have some anglers running a second RB100-HP for their electronics. For this application, a second battery is fine.
How much can I discharge my RB100-HP dual-purpose battery and still start my engine?
The RB100-HP can be discharged up to 70% (30% state of charge) and still start most engines.

Is it OK to connect my starting battery in parallel with one of my RELiON lithium trolling motor batteries to assist with starting if needed?
Yes, however, if you do so, it is required that you use a switch to isolate each battery so that they can be charged separately with a multi-bank charger.
How long will my RELiON lithium batteries live?
RELiON's Lithium Iron Phosphate (LiFePO4) batteries are designed to provide over + cycles at 80% depth of discharge.
Will my existing battery gauge provide an accurate state of charge for my lithium batteries?
Not if it is a typical lead-acid, voltage-based battery gauge. You will need to use a lithium battery gauge for an accurate state of charge.
What does it mean if the voltage of my RELiON lithium battery is '4-Volts?
Lithium batteries come with Battery Management System (BMS) to protect the battery from various abusive conditions such as low voltage, high voltage, high current and high temperature. If the BMS goes into protection mode, it will disconnect the battery from the terminals and the voltage will read between 0 to 4-Volts. If this happens, simply disconnect the battery cables and reconnect and the voltage should return.
How do I store my RELiON lithium batteries?
For long term storage, from 3-12 months, lithium batteries should be stored in a dry environment between 23°F to 95°F (-5°C to 35°C), ideally at 50% state of charge.
What type of charger should I use for my RELiON lithium batteries?
We recommend you use a multi-bank charger so that each 12-Volt battery can be charged separately to ensure they stay balanced and get fully charged. The ideal way to charge a LiFePO4 battery is with a lithium charger, as it will be programmed with the appropriate voltage limits.
How long will it take my RELiON lithium batteries to charge?
That will depend on several factors; how much your batteries were used and the output current of the charger. Lithium batteries can be charged faster than wet or AGM lead-acid batteries, however the charger needs to provide the higher current to do so.

What is the maximum current I can use to charge my RELiON lithium batteries?
RELiON Lithium batteries can be charged at a maximum current of 1C (C = the capacity of the battery). Ex. 80Ah RELiON lithium battery can be charged with a maximum current of 80A Refer to the data sheet for your battery for charge current specifications.
Do I need to charge my batteries each time I use them?
Unlike lead-acid batteries, lithium batteries do not get damaged if they sit partially discharged for extended periods of time. However, we do recommend you charge them after each use to ensure you have the maximum runtime available, every time you use your boat.
Will it harm my batteries if I leave the charger connected for extended periods of time?
No, you can leave the charger connected to your batteries indefinitely and it will not harm your RELiON Lithium batteries. The Battery Management System (BMS) in each battery will protect it from being over-charged.

lucl said: Click to expand...In most cases, the battery does not communicate to the rest of the system. However, some of the more advanced batteries do have communication methods that allow them to communicate with the rest of the system. Furthermore, all BMSs have a built-in shunt that allows them to calculate the current in order to do over-current protection. Smart BMSs (with blue-tooth or some other communication path) will almost always use the shunt to track state-of-charge and present that via the communication protocol.

Smart BMSs (with blue-tooth or some other communication path) will almost always use the shunt to track state-of-charge and present that via the communication protocol.Right now, the com ports are used mostly to communicate data, but not to coordinate among components.....but some advanced systems do coordinate.The challenge with tieing the BMS/Battery into the rest of the system over the com port is that there is no standard protocol. Therefore, even if everything has something like a CAN bus interface, the chances are good that they can not communicate and coordinate. Right now, systems that integrate and communicate well are systems where everything comes from the same manufacturer. As an example, Victron has ways to get their chargers, inverters, batteries, etc to all communicate and coordinate. We are starting to see some equipment that is designed to mimic the protocols of other manufacturers, but that is still the exception, not the rule. It would be nice if there was a standard for this, but I am not aware of anyone working on a standard.
