Really learning a lot from you. One thing I like about your video is the way you explain thing without too many words, just simple diagram and wording it accordingly.
Good info. I am perplex on how to install VSR and battery switch and if the latter is still needed. I have a wet battery for the starter/engine and two different batteries for the house.
Hi robercoles, Thanks for watching, usually you have the VSR or the battery switch. Rare are the ones that install both. Now I have a question for you when you say you have a wet battery for the starter/engine and two different batteries for the house. Your house batteries are what kind of batteries? Mixing of cells can result in battery leakage and sub-optimal device performance. You cannot mix AGM and flooded batteries within the same battery pack. AGM batteries should be paired together with AGM batteries of similar age and ratings within the same battery pack. Let us know 👍
Great video. If you had a solar panel instead of a charger, would you need a dual vsr to allow the energy from the solar to reach the starter as well as the house battery, or would you simply be able to wire the solar directly to both batteries?
hi brunoplayfaircal, Thanks for watching. Are you looking for this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VkG28P2Oc3c.html check it out and let me know :)
Thanks for your post it was very helpful. My question is .. when I’m at home i want to disconnect my batteries completely to prevent and draw (parasitic or if I left anything on by accident) where in the circuit can I wire a battery isolator/ main battery switch …. thanks in advance Rob
Hi robertevans, thanks for watching, usually people will put a VSR or an battery isolator not both. here is a video with isolator switch with position bat1, bat2, both and Off which your probaly looking for. Let me know :) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-USG1xZju1DA.html
Thanks for that Joe, very clear. I also have a 4 position isolation switch battery 1, battery 2, All Off, or Emergency Parallel. How would this slot in to this layout please?
Hi ME, I would take this setup: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-USG1xZju1DA.html and install a dual VSR between the 2 batteries. So positive of starter battery to red prong of VSR and the other prong of the VSR to the house battery. Install fuses on both sides to protect your VSR. Then you have ground left connect it on ground bus bar. That should do what you want it to do 👍. Let me know if it’s clear.
This way you can get away with only one battery charger like you had mentioned. I never done this setup physically but I would do it the way I mention over this comment. Let us know the results 🙂
@@joetheboatguy5394 Thanks once again Joe, so direct from battery + to battery + and not from post 1 of switch to vsr to post 2 of switch, right. Also is a dual VSR a different type of VSR? Mine has an earth wire, one sensing battery terminal post and then the 2nd battery terminal post.
Hi ME, you can connect at the switch or at the battery. In reality It’s the same thing since the battery is connected to the switch. What ever is less messiest for you. Now difference between single and dual VSR. The single will let voltage pass on one side only, so your charger should be on the same side as the alternator (starter battery ). A dual VSR will let voltage pass both ways. So your alternator is on the starter battery and your charger can be plug on the house battery and everything will work fine. Example: if you have a single VSR and put your charger on the house battery, your starter battery will not be charged by the charger. Won’t let the voltage pass.
I love to have your graphs on electrical for boats, am getting ready to wire a complete boat, have you ever thought of putting them on pdf format and selling them 😊
Great video!! One question. I have this exact set up and have purchased a VSR on Amazon (Spartan smart batter isolator) in your example you have a single bank charger. I have a dual bank charger. Would a 2 bank charger "confuse", fry or short out the VSR? I think this spartan brand one is a single vsr. I could also set it up with a single bank charger but which battery would I have the single bank charger connected to with a single VSR (your example shows the charger on the house battery but with a dual vsr?
Hi Kenny Clark. Thanks for watching and nice comments. The only reason I put the charger on the deep cycle battery on this video was to show that with a dual VSR doesn’t really matter what battery you plug your charger both batteries will charge. If it’s a single VSR then you would have your charger on your starter battery since VSR will let the voltage only pass one way. Now for the dual charger. With the VSR it’s not necessary of having a dual charger. But if you have a dual charger it should charge faster (depending on charger). Your VSR should not fry (check your VSR specification). Now this is what I’m saying but I haven’t seen your setup or equipment. What i have understood from your comment your VSR should be fine. In reality a dual VSR is just a switch that’s let voltage pass one way or the other when it over the voltage required by VSR….. no reason to fry in my opinion.
Let us know how your setup goes :) that is a good question about the VSR lifespan.... i don't have the answer, sorry :( Some people say it lasts years Some other 6 months but i suspect bad wiring or wrong use of the unit....
@@joetheboatguy5394 My VSR is already not working. I'm wondering if the dual charger ruined the VSR. It did work, I could hear it kicking on and off when the charger was connected. Then it had a red LED light for a while............now it's dead.
Hi Kenny Clark, How old are your batteries? Make sure both batteries can still charge and keep it charge. A faulty battery can cause problems. Let us know.
Hello gilleslagardere, thank you for watching. In reality You don't need to fuse both cables if one or more are suitably installed/protected and cannot short, but you do need at least one to protect the VSR from overload. If your VSR is rated 80amp then you can put a 80amp fuse. Hope this helps 👍
@@joetheboatguy5394 hi there, how do you know the rating? I bought on amazon a 12v 140 amp dual Isolator VSR. I need help. I don't want to get the wrong fuse. Thanks in advance for your help
If the specification of the VSR is 12v 140amp. Then you can put a fuse of 140amp. Some people put a little higher fuse like 15 to 20% higher, but if you don’t need more then 140amp then put a 140amp fuse. It’s safer.
Hi Larry Johnson, thanks for watching don't forget to subscribe :) Here are some differences. Isolator • Eliminate multi-battery drain when two or more battery banks are in a charging system • Perform as well or better than existing factory installed components • Designed to exceed OEM specifications • Solid-state electronics • Isolates each battery circuit and allows each battery to discharge and charge according to its own needs ACR • Automatically combine batteries during charging and isolate batteries when discharging and starting engines • Start Isolation (SI) protects sensitive electronics by temporary isolation of house loads from engine circuit during engine cranking • Hermetically sealed to IP67 • Dual sensing - senses charge on both battery banks • LED indicator light displays functionality and battery status VSR • Automatically combines two batteries when charging and isolates the two batteries when not charging • Footprint dimensions similar to battery switches • Robust Glass Fibre reinforced Nylon enclosure • Built-In LED function (On when VSR engages) • Manual Override capability • Surge protected circuits • Silver tipped contacts • Surface mounted complete with stainless self tapping screws ACR and VSR differ from a battery isolator? Battery isolators use one-way electrical check valves called diodes that allow current to flow to, but not from, the battery. ACRs use a relay combined with a circuit that senses when a charging source is being applied to either battery. VSR's, ACR's, Combiners, Parallel Combiners etc. and they all do just about the same thing. The term ACR is a trademarked term by Blue Sea Systems for their version of a VSR or voltage sensing relay Let me know if this helps
What I meant is all your negatives need to be connected. So if you’re all going on one negative of the battery, don’t forget to bring the other negative of the battery also. Basically, both negative of the batteries need to be connected together and the negative of the VSR to the negative of one battery
@@joetheboatguy5394 So Just run a wire from the negative of the "house" battery to the negative of the Starter battery, and also the negative wire from the VSR to either one of the negative terminals?
Hi Joe, Is there a need for a negative jumper between the two batteries, will it effect the system ? And what is the real effect of conecting the negatives of both batteries? Also I think this sensitive relay will work fine with the regular (1,2,both) battery switch right?
Hi Ali Al jarian, Thanks for watching, the answer to your question is yes you do need to connect both negative together to complete the circuit. On this circuit both (Battery) negative go on the Busbar. Yes, the Battery switch and the VRS can work together, its got to be wired right. Usually, one can replace the other but can work together also.
I'm about to hook up a 22$ boost converter that will turn 12V into 15V(10amp). If my starter battery goes out, I'll use the secondary battery to power up the VSR via the boost converter thats wired to a switch inside the cab. That way, I can basically use the VSR to link the batteries whenever & jump start my vehicle with the push of a button. 😁
Hi GigaTheory, thanks for watching. Be careful, If you install just a VSR without a switch than your start up battery will receive too much voltage and might damage the starter battery. Let me know what’s your setup. 👍
@joetheboatguy5394 the VSR is a switch. What do you mean? The vsr senses the Volt increase when the alternator runs to link the batteries(to charge 2nd)... so if my main dies, I need to physically use jumper cables to jump. My solution is to use a 12 to 15v boost converter to apply power to the VSR in that situation the VSR will think alternator is running and link the batteries. Viola a "jumpstart" using a button.
This is what I’m understanding in your setup. (I might be wrong, let me know) you have a main start up battery that starts your engine. And you have a Deepcycle batterie in the cabin to run equipment. They are both connected by a VSR so when engine is running your alternator is charging your main batteries and when voltage rises over 12.5V your VSR will connect to your second battery (deecycle battery) to charge that one also. Is this your setup? In this setup I’m talking about Single VSR. So, from Main to deepcycle. Let me know 😊 sorry its hard to figure out sometime without seeing.
Hi Joe, I have an idea. Can I run two LONG 6 gauge positive wires and ONE 6 gauge negative wire that are connected to 2 batteries at the back of the boat, inside the cabin to wire the ACR, the ON and OFF switch, the CIRCUIT BREAKER PANEL, the BUSBARS, and FUSES for easy access?
Hi Bean Iril, if you are only running one black 6-gauge wire back to batteries then depending on how long your wire is, you will be limited to 50Amp max if your wire is 19 to 22 feet. Make sure your ACR, switch and other equipment can handle the appropriate amperage.
@@joetheboatguy5394 -I have a 21 ft 225 yamaha walkaround and what i’m trying to do is, placing the start and deep cycle batteries inside the cabin, about 14 ft away from the motor, using perhaps 2awg positive and negative wires and build everything from that point on, like the acr, switch, fuse panel, circuit breakers, and solar panel for a clean and easy access. Do you think the 2awg good enough to crank the motor?
Hi bob novak, thanks for watching, I was actually working the video for solar panels, it will come out this week or next week. I will let you know when it’s out 👍
@@joetheboatguy5394 outBoard. Also a power steering pump.. and why are the hoses labeled green and red port and starboard ? Left and right ? I installed two starboard one time. And sold it. I haven't heard from the guy since
Hi Darkone Mylife, I’m more of a electronics tech, when it comes to water pump, sorry I can’t really help you. I have not done that. I work more on small bass boat. For the outboard and connection to handle and steering wheel that I have done but don’t have video 😟. I will see if I can make one soon.
Hi ultimatejay, thanks for watching. Adding an on/off switch is an option, but it will only lead to human mistakes. In the event that you turn off your switch and plug in your charger, your batteries may not be charged the following time you want to go out. So, adding a switch on batteries can be a double edged knife.
