In brief. A power distribution unit replaces the cluster of cable lugs on the battery terminal: one connection, one protected output for each accessory, and the ACC wire that switches everything off when you remove the key. On Endurrad, there are the LOBOO CB20, with three outputs rated at 20, 15 and 10 A (480 W total stated), and the CB10, with a single output of up to 30 A (360 W stated).
The choice is made with a calculation: divide the accessory's watts by 12 V to get the amperage to put on a channel. Here you will find the manufacturer's stated protection thresholds, which channel is for which load, what the ACC wire does and does not do, and how to install it. It works on any motorcycle with a 12 V system because it is not a model-specific product; the stated input is 12-15 V, so it is not suitable for 6 V or 24 V systems.
Why you need a distribution unit
Every electrical accessory you add seeks the same thing: the battery terminal. After the third one, the terminal is a cluster of overlapping cable lugs.
- a single connection to the battery, instead of four cable lugs on the terminal;
- accessories turn on with the key and switch off when you park, without switches and without the risk of leaving something on;
- if an accessory shorts out, only its line is disconnected, not the entire electrical system;
- below a voltage threshold, the loads are disconnected and you retain enough power to start the engine.
- is neither a battery charger nor a maintainer: it distributes power, it does not recharge;
- is not a jump starter;
- does not replace the fuse near the battery: it is additional protection, not the only one.
This is the step worth taking when auxiliary lights, heated grips, a USB socket and a navigation device coexist on your motorcycle. For the lighting section, see the motorcycle auxiliary lights comparison; for the USB-C socket, see the guide to the 100 W socket.
CB20 or CB10: the choice in one table
It is the same product in two sizes, with a shared manual and photos. The number of lines changes, not the philosophy.
| Feature | CB20 · three outputs | CB10 · one output |
|---|---|---|
| Outputs | OUT1 20 A, OUT2 15 A, OUT3 10 A | One only, up to 30 A |
| Rated power | 480 W total | 360 W |
| ACC wire | To be connected: turns on and off with the key | Not necessary |
| Destination specified by the manufacturer | OUT1 for high loads such as spotlights, OUT2 for medium loads such as heated grips, OUT3 for low loads such as USB sockets and a navigator | One large accessory on its own |
| Endurrad price | 72,00 € | 59,00 € |
Which one to choose
The CB20 is the answer when the loads differ from one another and it makes sense to keep them on separate lines, each with its own indicator: one light going out does not switch off the phone socket. The CB10 makes sense when there is one major accessory to power, such as a pair of spotlights, and you do not want to depend on the ACC wire. If you have three or more accessories, the CB20 saves you from having to add up ring terminals again.
Calculating amps: from wattage to channel
The wattage is written on the accessory. For the system, amps are what matter, and they are calculated by division.
Why the 480 W is not the sum of the channels
The three channel maximums add up to 45 A, or 540 W at 12 V (calculation). However, the LOBOO panel specifies 480 W total for the CB20, equivalent to 40 A at 12 V (calculation). These are two different limits: the limit per line and the overall limit. In practice, the three channels should not all be pushed to their maximum simultaneously.
| Accessory | Power draw | Location |
|---|---|---|
| LOBOO C36 USB-C socket | 130 W specified, at least 10.8 A at 12 V (calculation) | OUT1 or OUT2. Not on OUT3 at full load: 10.8 A exceeds the channel's 10 A |
| LOBOO L11 spotlights | Power not specified in the datasheet | Check the wattage on the rating plate and divide by 12; the high-current channel is OUT1 |
| LOBOO CP06 compressor | Current not specified in the datasheet | Powered at 12 V from the cigarette lighter or battery terminals: check the rating data first |
| Navigator or charging mount | A few watts: read the value on the power supply | OUT3, specified by the manufacturer for low loads |
Declared protection thresholds
The manual gives precise values, not a generic “multiple protections.” This is the manufacturer's table.
| Protection | What happens (LOBOO data) |
|---|---|
| Undervoltage | Below 11 V, the OUT2 and OUT3 indicator lights flash slowly for one minute, then the outputs switch off. Below 10 V, OUT1 follows, with three minutes of warning |
| Overvoltage | Above 24 V, all outputs switch off and the indicator light goes out. Rated withstand up to 55 V |
| Overcurrent | Over 25 A on a single line: automatic shutdown and indicator light flashing rapidly |
| Short circuit | Immediate shutdown of the affected line |
| Overtemperature | Above 80 °C, the device switches off by itself |
| Reverse polarity | If the positive and negative are reversed, the device does not deliver power |
Why undervoltage really matters
A battery drained by accessories while the motorcycle is switched off is the most common reason for a failed start. With the 11 V and 10 V thresholds, the control unit first disconnects the medium and low loads, then the high load, leaving enough power in the battery to start the engine. It does not replace a healthy battery: to understand which one to choose, see the adventure motorcycle battery guide, and for long periods of inactivity, how to keep your battery alive in winter.
The ACC wire: accessories follow the ignition
It is the connection that transforms the control unit from a «junction box» into a system that never leaves anything switched on.
How it works
On the CB20, the ACC wire must be connected to a point on the motorcycle that carries voltage only when the ignition is on. When you turn the key, the outputs turn on; when you remove it, they turn off. The CB10 does not need this: one output only, with no ACC wire to look for.
What you receive and how to install it
The three Endurrad questions: will it fit my motorcycle, what do I receive, and how do I install it?
- the motorcycle's system is 12 V (declared input 12-15 V);
- the battery is lead-acid, AGM, maintenance-free, or lithium iron phosphate;
- there is space under the seat or in the compartment: it measures 72.8 × 50.4 × 16.9 mm and weighs 127 g with the cable and indicator light.
- it does not work with 6 V or 24 V systems;
- there is no model-specific compatibility: it is a universal accessory;
- it is not designed for areas with direct high-pressure jets: the rating is IP65, dust-tight and protected against water jets.
What you receive
According to the manual's parts list: the control unit, three output cables with female connectors, eight heat-shrink solder rings, fifteen cable ties, and the battery maintenance card. The kit photos also show the power cable with a fuse holder; the fuse rating is not specified in the product specifications. The manual in two languages can be downloaded from the product page.
- Choose the location. Near the battery and protected from heat and moving parts. With its IP65 rating, it is well suited for mounting under the seat.
- Disconnect the battery. Disconnect the negative terminal first, then the positive, and reconnect them in reverse order when the work is complete.
- Connect the power supply to the battery. Positive and negative, observing the polarity: reversing it stops the power output, but it is not a good test to perform deliberately.
- Connect the ACC wire (CB20 only). To a point that carries power when the ignition is on.
- Connect the accessories to the outputs. Put the highest load on OUT1, medium loads on OUT2, and low loads on OUT3. If you need to extend a cable, use solder seal connectors: strip the section, insert a wire into the ring, cross the two conductors, heat it until the solder melts, and then shrink the sleeve. No crimping tool is needed.
- Secure it with the cable ties and test it. With the ignition on, the indicator lights for the connected outputs should illuminate; with the ignition off, they should turn off.
Limits and data that LOBOO does not specify
It is better to know this before ordering.
What is not stated in the specifications or manual
- Supplied fuse rating: the fuse holder appears in the photos, but the amperage is not specified.
- Quiescent current draw: the current drawn by the control unit with the ignition switched off is not specified.
- Cable cross-section: the output cables do not have a specified cross-section in the specifications.
- ACC points by model: there is no motorcycle-by-motorcycle list. On motorcycles with CAN bus, it is advisable to ask first.
