96 speedster battery?

[cncsignman]

Looking to replace the battery in my 96 speedster. It has been converted to use one battery plus we have added a stereo system with a 2600 watt amp. What size/brand battery would you recommend? Should I add a dedicated battery for the stereo or just get one big battery?

Most of the recommendations I have seen is to run a second battery just for the sound system

I run dual batteries with a ab switch so if you kill one you have a back up. Makes charging easier just turn the switch to off and charge don't have to disconnect the cable.

I have a 4-Tec Speedster. I'm thinking about this same topic for my boat. The boat came with a group 24 battery. I have a few options to consider.

Keep the g24 battery and add an EC5 plug for a lithium boost box.

Upgrade to a group 27 battery and add an EC5 plug for a lithium boost box.

Keep the g24 battery and mount a second smaller boost battery from an RXP.

Mount two group 24 batteries. With an A/B switch.

Do I want the weight of two batteries (I'm considering carrying more fuel which adds weight too)? Will the charging system be able to charge two discharged batteries without blowing a fuse?

With an A/B switch, can you switch batteries while the engine is running?

If you get a battery isolator, do you no longer need an A/B switch? Can you use different sized batteries with an isolator or do they have to be the same size batteries?

I never tried to switch to the other battery when the boat is running. I am assuming you can as long as you don't pass off to kill the power. I think wiring the AB switch gives you more control. Its basically is the same thing but but the isolators do it automatically for you. I don't see why you can't use different size batteries. I use the same class in my boat but they are different types and amps and that. The isolator take place of the AB switch

So you charge the discharged battery once you get home? That works for me since that's what I would do if I carried a boost battery on board.

I usually switch batteries when I beach the boat. I charge the batteries when I get home.

I will definitely go with a separate battery for the stereo So which would be the easiest way to go... A/b switch or isolator?

An isolator is easiest because they charge each battery automatically. http://www.***********/gp/aw/d/B00400IYTK?psc=1#productDescription_secondary_view_div_1454008511035
