Would a 3 amp inline fuse be correct? Running direct from marine 12v battery.

3 amp should work fine. If its not mission critical, you could start with a 5 and be ok. If its mission critical, i would go with 5a. These regulators do get hot if you're dropping down a lot of voltage. I use them to fun 12v leds of a 16v source and the linear regulator stay room temp. If i drop from 16 to 5v, it can get warm to the touch after long periods of time. That may blow a 3 amp fuse. I add an aluminum heatsink made for RAM on top of the coil, and it helps with the heat when you are dropping a lot of volts. For the price, it cant be beat.

I do not know. I assume you are hooking them parallel (? Is that right?) to keep the voltage at 12 volts, but longer run time. I have a deep cycle cell on mine, but have three motorcycle batteries and I have been thinking of doing this to get maybe more amperage. Don't know if there is more amperage. I don't know why you could not hook more up as long as you don't increase the voltage. How do they show hooking up the two motorcycle batteries? To get more amperage at 6 volts or increase voltage to 12? Sorry, a lot of blather here without saying much. I would be interested in what you decide to do. Good luck. I do not know.

Well its a replacement for a 12v system...I don't know what the exact range on it but you may be able to contact shoreline marine and ask them.

you are running on a 12 volt system I use 15 amp fuses, but I check my draw and output accordingly and don't push more than I need or run more circuits and have switches, like 6 flood lights and a separate circuit for appliances/tools, depends on your 12 volt battery, a trolling motor steady draw or a faster high output for tools with a short draw.

It comes with an inline fuse so yes, it can be connected directly to the battery. In my case I connected it to an auxiliary fuse block I already had installed.

It doesn't require an inline fuse. It is very low wattage. Sorry I couldn't help.

Not sure, The unit is designed for 12v deep cell low amp batteries used on boats to power radios, fish finder and lights but not to start high amp engines batteries to start car and boat engines.

Be sure the circuit (fuse) has the capacity to handle the load. I have an aux. battery in my van and charged from a Wagan Quick Jump Starter and it blew a 20a fuse after a couple of days of plugging it in. Be sure you isolate the aux battery in some way or your batteries will try to drain each other.

It uses a 200 AMP ANL Fuses. Make sure that the lead wires to the inverter are no longerthen 4 feet and are at least 2/0 (two aught) wire in thickness. Use two heavy duty marine gradebatteries in parallel maintaining a longer drain@ 12 volts.

Would recommend the 12 VDC approach. My 36v cart is wired to two batteries to supply all the aux items. And to your point, a fuse is an inexpensive insurance policy for when the powered device fails. Good luck

No, there is no onboard fuse so you should def add one inline with your power source.

Go with two high current 12 volt deep cycle batteries. Wire them in paralell; not series. You only want 12 volts; not 24. Use the same brand/capacity and type. Don't mix brands or current ratings. THE HIGHER THE CURRENT RATING;THE MORE TIME YOU'LL GET ON THE BATTERIES. I've seen systems with more than two batteries however, you'll need additional equipment to pull it off safely. You could also use a marine A/B Battery transfer switch and draw from bat A bat B BOTH of OFF. Don't forget to use fuses at key points. Amazon also has some pretty good books on the subject.

I have three batteries on my boat each is connected through an 80 amp continuous solenoid. The set up works fine it keeps me from having to open the hatch to turn the batteries on and off each time. ALWAYS remember to turn off when not in use or leave the battery charger on otherwise they will run the batteries down. Hope this helps. Charles

You can never go wrong adding an in-line fuse right of the battery connection. Most professional installs will place a fuse in the first 6-12 inches of wire/cable. The distance of the cable and constant watt draw does matter on the size of wire used. I will be using 4 AWG since I will be running it over 15 feet or so for a permanant mount in my truck. If they are recommending running 8 AWG wiring, it would be a 100 amp fuse by US standards for 12v applications. This would be at a full load.

I bought a 12 volt battery for an atv/motorcycle. I bought two small alligator clips( red and black) and attached them to the ends of the wire. Then just clip red to + terminal and black to - terminal. I don't submerge mine in the water so I had to adapt an intake hose. You'll need to suck on the output hose until the water gets through the pump. You'll need a small 12 volt charger for your battery. Not expensive, think mine was about $17. Hooking it up to computer power supply is probably not the best idea.

I'm sorry we have only had our battery for a little over a year & used it once during Hurricane Sandy October 2013 & did t have an issue with a marine battery I think it is 75 amps. I took the book to a store called batteries plus & they gave the suitable waterproof battery with a 3 yr warranty. Hope that helps a bit.
