BATTERIES AND USE

1. WHICH BATTERY DO I NEED FOR MY ELECTRIC OUTBOARD OR TROLLING MOTOR?

The AV line (AV stands for Adjusted Voltage) has been specially developed for use with 12V trolling motors. The voltage of our other (Angling line) 12V batteries is slightly higher than that of a lead battery. Always consult the manual of your electric outboard or trolling motor and use these battery only if your electric motor accepts an input voltage of up to 16.8V, otherwise you should always choose an AV battery. The 24V batteries work with all common 24V electric motors. If in doubt, consult the supplier of your electric motor. See also question 11 What are the differences between the Angling and the AV line?

2. HOW DO I SAFELY CONNECT MY ELECTRIC TROLLING MOTOR TO A REBELCELL BATTERY?

Use cables of sufficient thickness and (ANEN) plug connections to connect your electric motor to the battery for safe use and always place a suitable fuse between the battery and electric motor to protect both. Never use crodocile clamps to connect your trolling engine to the battery! These connections are not safe and can lead to a large heat development with dangerous situations and damage to your electric motor and battery. Damage due to incorrect connections and cabling is expressly excluded from the warranty. Make sure that you always tighten the screw terminals of the battery (with a socket wrench, for example).

Tip: the Quick Connect EM cable has been specially developed to safely connect your electric motor to a Rebelcell battery.

3. How long is the runtime with my Rebelcell battery?

This depends on the type of battery, capacity of the battery, the power of the trolling motor and the circumstances (currents, wind, temperature). More information about this can be found on the product page of each battery. We recommend that you ask the supplier of your electric outboard motor for advice on the correct battery.

4. How can the 12V50 Angling li-on battery replace a 12V105Ah lead-acid battery in practice?

This has to do with the lithium battery technology. Unlike lead-acid batteries (which can be discharged to a maximum of 50% to 70%), all our lithium batteries can be fully discharged (100%). In addition it makes no difference for the capacity of our batteries if you discharge in 20 hours, or in 5 hours. This is not the case with a lead-acid battery: the usable capacity for discharging in 5 hours is much lower than for 20 hours with a lead-acid battery. The actual capacity of a lead-acid battery can be up to 35% lower than the sticker capacity if discharged quickly, as a lot of energy is lost in heat and cannot be used to power your e-motor.  It is a bit like an old fashioned light bulb vs a LED: a 60W light bulb gives the same amount of light as a 10W LED, as a lot of energy is lost to heat (and this is not the case with a LED).  As a result of these two factors in practice the effective runtime of our 12V50 li-ion battery is comparable to a 12V105Ah lead-acid battery. This has also been tested and confirmed by both Carp anglers and Predator anglers.

5. How deep can a Rebelcell li-on battery be discharged?

All Rebelcell batteries are protected against abuse through an integrated battery management system (BMS). The battery can be fully discharged (up to 100%) without negative effects on user life or performance. It is recommended to charge the battery as soon as possible if it is fully discharged.

6. Can I use the 12V battery with a 24V E-Motor/trolling engine?

That is not possible, and we strongly discourage it. When the batteries are connected in series the voltage becomes too high for safe use with your 24V E-Motor, and it can create irreversible damage. For 24V electric outboard engines we have developed the 24V batteries.

7. Can I use a Rebelcell battery with a 12V DC/230VAC converter?

This is possible, but you need the right converter. For the Angling line you will need a converter with an input voltage between 12-17V and for the AV line with an input voltage between 9-15V. Most converters, however, need an input voltage between 10-15V, so they only work with the AV line but switch off if the battery falls below 10V. Consult the manual of your converter for this.

8. Can I use a Rebelcell Battery with a fishfinder?

Yes, that is possible. The vast majority of fish finders (with input voltage 12V-17V) can be connected to the battery without issues. Certain types of fish finders (like the Raymarine Dragonfly series) have a lower input voltage. To use the 12V25 / 12V50 battery with these fishfinders you need to place a DC Stabilisor in between the battery and the fishfinder. This Stabilisor will slightly lower the output voltage of the Rebelcell battery and therefore make it suitable for the Raymarine Dragonfly. The 12V18 AV battery can be used with all fishfinders (including the Raymarine Dragonfly) without any other converters.

9. Can I use a Rebelcell battery as a starter battery for my outboard or my car?

That is only possible with the Rebelcell start. This Battery has been specially developed as a lithium starter battery for outboard engines up to 200 hp. All other batteries are designed for discharge over a longer time such as with an electric trolling motor and are unsuitable as a starter battery. The peak current required will damage the battery. Rebelcell batteries cannot be used as a starter battery for a car.

10. Are the batteries waterproof?

Our batteries are splashwater proof according to the IP54 standard. They cannot be fully immersed in water or handle heavy rains. To avoid problems use a waterproof battery container and position the battery upright on a slightly elevated level so that it is not continously standing in the water, or water can enter via the top of the battery.  If you use a battery carrying case please ensure that water (from rain for instance) remains in the battery bag as this can damage the battery. Water damage is explicitly excluded from our warranty terms.

Tip: The Rebelcell Outdoor Boxes are a robust, waterproof power source and specially developed for use in wet conditions such as carp fishing and electric boating.

11. WHAT IS THE DIFFERENCE BETWEEN THE ANGLING AND THE AV LINE

The Angling line batteries (12V50 Angling, 12V100 Angling – color black) have been developed for short use in angling (short sailing at a low setting, trolling at low speed with predatory fishing etc). Because the voltage is somewhat higher (12.0V-16.8V), they are less suitable for long-term use such as for an electric outboard.

The AV line (AV stands for Adjusted Voltage) batteries (12V35 AV, 12V50 AV, 12V70 AV, 12V140 AV – color blue) have a lower voltage than that of the Angling line (9.oV – 12.6V). The AV line has been developed for both short and long-term use. In addition to fishing, the batteries from the AV line are frequently used as a power source for electric boating with an electric outboard engine.

CHARGING

1. How long does it take to charge my Rebelcell battery? And can I partly charge my battery in between full charge cycles?

The charging time of each battery with the different battery chargers can be found on the product page of the battery. For example, the 12V70 AV can be fully charged within 4-5 hours with the 12.6V20A . You can also recharge the battery in between charge cycles. The charge cycle can also be interrupted or not completed without affecting the performance or life of the battery.

2. Can I charge my Rebelcell battery with a lead-acid battery charger or any other charger?

That is not possible. Lead batteries are charged at a different voltage and with a different charging profile than our li-ion batteries. Most Lithium chargers are also intended for LiFePO4 batteries, and not for the Li-ion batteries from Rebelcell. We therefore recommend that you always charge with a Rebelcell charger.

3. Can I charge a Rebelcell battery with a solar panel?

Yes, that is possible. You do need a special solar charge controller that provides the correct voltage and charge profile for our batteries. The Solar charge controller indicates which model you need for which battery.

4. How can I best charge the batteries if they are not used for an extended period of time, such as winter storage? 

We recommend charging the batteries to 50-70% capacity if they are to be stored, to disconnect the charger and all other equipment and cables from the battery terminals and ,If applicable, to turn off the power button on the top of the battery. Because there is hardly any self-discharge (~ 2-3% per month) the battery will not be empty at the end of winter. No trickle charger is therefore required. For the first use after storage we recommend to fully charge the battery.
