![]() ![]() I was actually thinking about moving the house battery next to the starting battery. I think there is still plenty of room to mount the ACR/switch close to the starting battery. However, an ACR and proper switch is far better, or just stick with the simple switch.Re: Do I want a VSR, Isolator, ACR, or Switch. If you wanted to attempt this, you would wan this type Alternator current would pass to the battery, but no current would pass back to the switch. Wiring like you talked about, remember and putting the diode in line between one of the batteries and the switch, will not work. Not going to go into it as its been debated a number of times. The issue with a 2 bank diode isolator paired with a traditional 1/2/both/off switch, in order to make the diode most effective, you would have to wire all your house loads direct to the house battery. Most have migrated to ACRs and VSRs like from blue sea and BRP Marine or simply stuck with a simple switch. This has been done in the past by many boat builders. Something like a stud type diode maybe but how many amps are the alternators in our boats throwing out? if over 100A then not sure if i can find a bigger one or if two of these in parallel could work ? for leaving on 1 always but having number 2 as back up to start if needded? then switch back to number 1 and leave it thwrw always?ĪCR is more expensive so u can isolate each way vs this may work if u plan to always be on 1, and 2 is just back up? tboughts? but in respect if u are on number 2 only you would NOT be charging number one because the diode is blocking it going back to 1.Ĭouldn't this be cheaper than an ACR. ![]() but no discharge can come from number 2, until the switch is turned to 2 or both. then simple jumper between negatives on 1 and 2? both are connected in parallel but with a diode on at least the positive side acting like a 1 way check valve allowing it to be charged but not discharged unless fully connected in parallel via switch set to both? I realze most diodes have around half Volt drop but good enough mYbe. In the meantime I'm developing a boat lift wake boat charging kit that will charge both batteries while I'm gone all week so i can monitor whats going on.Ĭouldn't you use like a 100A one way diode on the positive of 1 to positive on 2. after that incident I was planning on switching to number two at the sambar leaving number one for everything else ut my num er 2 seems to always be low or it coukd be that it has t cbarged back up, as when I'm on both i get a lower voltage than when on one only which means number 2 is pulling nimber 1 down. I switch back to both to run around for a little bit to charge it up the past couple of days but when I switch to number two it still shows low battery so I have to leave it on both ,or 1 only so either I have a bad number to battery or it's not charging or charging well. seriously malibu the low battery warning should be at a level that still allow starting the boat! both mine died low bat warningat the sambar so I mediately tried to start the engine and I was out of luck unfortunately mine was on both at the time so both batteries were run low. Strange but something I'm i interested in as well. Then when I switch to #1 everything seems to be fine. I tried using and running on both, but even when I do that I still get a low voltage warning when starting the motor. I read somewhere that you are supposed to primarily use #1 for nearly everything, and rely and #2 as a backup. ĪFAIK, ACRs are not a factory option so the only way the OP has an ACR in addition to a selector switch is if one were installed after-market. You're referring to an ACR, which is different than a battery selector switch. I use my on board charger religiously and still have the factory batteries 7 years later. I leave my switch set to the house (radio) battery so if it is discharged too low my starting battery is not affected. The key thing to note here if I am reading this correctly is that both batteries are always being charged regardless of switch position, but if you combine them 1+2/ALL both batteries will be discharged. Battery Isolators and ACRs are intended to distribute current from a charging source to all batteries, but leave the batteries isolated during discharge conditions so they are only impacted by their own loads. ![]() The reserve battery system is used for vital loads like engine starting, navigation or communications. Straight from Blue Seas web site: Battery Isolators, Automatic Charging Relays (also called ACRs, combiners, or voltage sensitive relays) are all intended to keep a load (or loads) from discharging the reserve battery system. ![]()
