running battery and keeps my trolling motor batteries charged while the engine is running. I have a LF150C/D four stroke outboard. Q1-Does Yamaha have any experience with these devices? This device switches from charging a fully charged running battery to a partially charged trolling battery on one minute intervals, Q2-Will this negatively affect the life expectancy of my volt regulator or alternator? Q3- According to my motor manual the voltage regulator maintains 13 volts output when charging. For this device to work it requires the bat voltage to reach 13.7 volts. Q3- Is this accurate? Otherwise this devise will not work.

How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
The VSR allows for two batteries to be charged at the same time. When the engine is started, and the start battery reaches 13.7 Volts, the relay closes, Combining the battery banks (start and house) and allowing them to be charged simultaneously.
The Voltage Sensitive Relay (VSR) allows two batteries to be charged at the same time. When the engine is started and the start battery reaches 13.7 volts, the VSR engages, allowing two battery banks (start and auxiliary) to be charged simultaneously.
Attach both red cables to the VSR. The cable from the start battery goes to the stud on the VSR with the painted RED DOT and marked “Positive + Sense Batt”. The cable from the auxiliary battery goes to the unpainted stud and marked “Positive + Second Batt”.
Disconnect the leisure battery , make sure the terminals are safely isolated from each other and the van, start the engine, wait a minute and check the voltage at the ends of the leisure battery leads, if you get 13. – 14 volts there the relay is working ok, switch the engine off and this voltage should disappear.
Yes, however, you would not be able to use an older VSR (Voltage Sensitive Relay) system. This is because the relay merely allows the alternator`s charge to be passed to the leisure battery, usually at a fixed voltage.
Any circuit that includes an auxiliary battery that needs to be charged from an alternator source needs a DCDC charger and not a VSR. The only real exception is vehicles with fixed output alternators that provide a constant output voltage over 14.2V and with a similar or same battery to the cranking battery.
A 5V relay module is a single or multi-channel relay module that works with a low-level trigger voltage of 5V DC. The input voltage can be from any microcontroller or logic chip that outputs a digital signal.
It is a switch that comes with an electromagnet to close or open a circuit. Mostly, it uses an armature, an electromagnet, contacts, and a spring. Generally, a power relay gets power from the battery source, and the electromagnet draws the armature. Also, it includes a moveable arm made of iron.
There are three key wires in the loop: a positive wire for the battery, a sensing wire for voltage, and an igniting wire. The ignition input wire is linked to the engine. The energy detection cable monitors voltage and transmits it to the converter, while the energy wire links the alternator and the engine.
It is typically used to prevent over-discharging of car battery and is very common in a dual battery system. A VSR is usually classified into 12V / 24V range with varying amperage. A single sense relay only detects voltage at one pole while a dual sense relay detects voltage at both poles.
Take the leads of the multimeter and connect them across the coil terminals of the relay. For a normal coil, the multimeter should read anywhere between 40Ω to 120Ω. If the coil is damaged i.e., it is open, the meter shows out of range and you have to replace the relay.
To test the leads, connect a multimeter between the leads of each relay and check the resistance value. If the Relay is On (closed circuit), you will see 100 mO of resistance for the 10 Amp Control Unit, or 50 mO of resistance for the 30 Amp Control Unit.
In theory the large current flow through the VSR will drop the starter battery voltage and so trigger the relay to open circuit and so switch off this circuit stopping the drain and saving the day.
12V 100Ah LiFePO4 batteries are currently some of the most popular for off-grid solar power systems. They`re a drop-in replacement for 12V lead acid batteries, and a great upgrade. They are fully charged at 14.6 volts and fully discharged at 10 volts.
VSR Operation: The Voltage Sensitive Relay (VSR) allows two batteries to be charged at the same time.
VSRs can also engage and disengage frequently with the large and rapid voltage changes from a smart alternator and so the high current contacts may fail prematurely.
You can use a 32A fuse for each battery. Use real thick wires! and as short as possible. One voltage drop over a wire uses 83 watt, that will fry your wire for sure.
If a fuse is used with a voltage rating lower than the circuit voltage, arc suppression will be impaired and, under some overcurrent conditions, the fuse may not clear the overcurrent safely.
Voltage relays are used to detect rapid increases in voltages due to generator failure, low voltages caused by power interruptions or short circuits, etc.
All automotive relays work on 12 volt power (there are relays for 6 volt electrical systems, but most commonly available relays are designed for 12 volts). You need 12 volt positive and ground to trigger any relay. This is done on terminals 85 and 86.
If the relay fails it will cut off power to fuel pump and ignition system, which will result in a no power, and therefore no start condition. You may find that turning the key may power on the accessories, and may even crank the engine.
Wire or cable is usually classified as high voltage if it is rated for over 1,000 volts. High voltage can be used to describe a single wire or a multi-conductor cable. Wire or cable that is classified as high voltage is typically used for electrical power transmission.
YES you can and we did many times.. . BUT, they must all be the same chemistry, and preferably the same manufacturer and even same type.. . . Don`t mix brands if you can avoid it, and NEVER mix different chemistries . . Don`t even mix wet-acid with AGM or Gel.. . .
Step 1: Fully discharge your powerbank. Step 2: Plug the USB voltage current meter to the USB power source. Step 3: Begin charging the empty powerbank and start timer. Immediately take note of the Amp reading.
