Can you recommend a good lightweight secondary battery for a motorcycle. I plan to install in a saddlebag.

[@YugiSatan]

So, currently have an 07 Civic Hybrid. I know it has a DC/DC converter instead of your typical alternator. So, how would I go about running a second battery in the trunk? I don't like running everything off the 12v under the hood. Current setup- BOSS BV765B 4x QEA QRS65 2x QWX2000-12D4 QEA800.2(adding fans to this today as it overheats and goes into protection mode after a while of playing at high volumes when there's constant highs&mids) QEA2500.1D(this stays relatively cool, only gets warm to the touch really)

@@reyesjose214 yes it will definitely kill both your batteries w/ this typical way of installing a 2nd battery! I'm going to be installing my 2nd battery sometime this week cuz I JUST received my Stinger battery isolator today, (THIS is the part that is missing in this style of install, that will allow you to be confident that you will never have a dead car battery to start your car w/!) You can get an 80Amp stinger like I just received on Amazon for just some pocket change more than $15 greenbacks! Then the installation is more or less the same layout & same amount of wire needed etc, etc..... Just 1 ignition sourced ground location is your only other step involved in an isolator set up... FYI, if you have an extra $20 you can live parting ways w/I'd advise you to go the isolator route, if for nothing else, just piece of mind knowing you'll NVR need to stress bout weather or not your ride's going to start or not (due to audio installation issues that is) cuz you let your stereo play for a few minutes after the engine is shut off.... just MHO....To each their own of course....

He's doing it correctly to.. A lot of people won't ground the secondary battery and it will kill their Alternator" or they"ll Ground it to a capacitor thinking that will work! The best way to do it is already laid out have the amp ran Normal get the "Converters" run the power through them and ground both batteries..Also Kids Learn As they get older like me lol! But Most Deff Hook Up A CrossOver for the bass you'll never go without one again And If Yur Doin 2 Batteries Run the Big 3!!

but adding a battery isolator will prevent the sub amp from using power from the main car battery. Its just running from the 2nd battery and charging from the main one. The only benefit from that is you now have a very short length power wire from battery 2 to the amp. Zero extra capacity

[@G3RMZONE]

when is a battery isolator needed?

[@christopherhaynes8633]

Battery Isolator is good when you want to listen to the radio while the car is off. This is so that if you listen to the radio for too long, the car will still start. If you only listen while driving or the car is running there is no benefit to it. For me it is useful as I have a van and like to hangout in the van and listen to music without the engine running. If I fall asleep or leave the radio on by accident, I know that the van will still start up when I want to drive away.

[@nathanielthomas2502]

@@christopherhaynes8633 With an isolator, where should the 2nd fuse be placed after the one up front? Should it be placed just before the isolator, right after the isolator before the 2nd battery or both?

[@adamnelson9661]

The batteries will end up drawing off each other and shorten their lifespan. Really bad idea unless you have matching batteries. Usually it’s the smaller battery drawing off your more expensive battery.

[@tw6946]

Why would you ground amp and battery in different spots? That causes ground loop issues and unwanted interference

[@tw6946]

At least that's what I researched. I really don't know I just want to get it right the first time

[@ProvoBeastAudio]

Ground loop is from poor grounds in general and low quality rca cables. Grounding an amp different from a secondary battery has nothing to do with that. Don’t believe all the “research” you have.

[@humptydumpty8976]

Rob J No you’re right. They should eventually upgrade the battery. But like they said it’s only hooked up to a 5 channel so no need to upgrade the alternator.

[@Aedan-Silk]

Awesome video, very clear! Couple questions though.. Should the fuse from primary battery to secondary battery match the rating of the fuse from secondary battery to amp? Also, does running two batteries require an upgraded alternator on most vehicles? Thanks

[@ProvoBeastAudio]

For starters, it depends on how many amps you are pulling as the alternator is charging those batteries. So to answer your question, yes. You alternator will need to charge those batteries, so if your system is bigger than your alternator can support, then eventually it is recommended to upgrade.

[@kevingrafton5397]

Great video, clean set up. So this isn't in parallel to use power from both batteries?

[@jeffdeering3886]

Jeff Deering you don’t always have to. If you’re doing a crazy system you might have to. If you have problems keeping up a charge maybe try an isolator first

Hi guys. Great video. I'm learning everything i need to know to install 2 new amps in my car. (my old amp finally died) My sub amp has 2 zero gauge power and ground hook ups. My mid range amp has one 4 gauge hook up for each. (DD audio M4b and SS4b) I'm running zero gauge and upgrading fuses. My previous installer had run the ground wire all the way from under my engine bay to my 2nd battery in the trunk. Was that a waste of wire? Your video here makes running new zero gauge ground wire from the engine bay to the trunk battery look unnecessary. I would appreciate some reassurance that for my application it's ok to ground closer to the trunk somewhere. thanks.

[@yellobelly420]

You'd be better running a ground from battery to battery as long as its gauge is think enough to support the current. Copper is more conductive the steel! Also should eliminate posible grounding issues

[@danieldouthitt1415]

Your ground should be same as positive nothing less and I don't see a purpose of bonding both batteries as long as the factory ground tensile wires have been replaced hopefully with the big 3 that should be done before a second battery

[@bobbyz3125]

Yeah, I hear you about the warranty. I would definitely check on that b4 doing any modifications. I'm not an install professional but upgrading your "big 3" makes a big difference with your voltage. If you can't install like a 300 amp alternator see if you can upgrade the big 3. Which is replacing 3 main cables on your vehicle. The batt ground to the chassis, the chassis to the engine block, & the alternator plus to the batt plus. You'll go from 4 ga to 0/1. Plus a capacitor tends to help as well. I'd say go for 1 farad for every 1K Watts of RMS. I know a little bit but it would be better to talk to a pro. I don't know what you're running but good luck and keep the dB's up 😁
