Watch the bass Posted September 26, 2013 Report Share Posted September 26, 2013 Try it out, and if you have electrical problems, fit up later. "in the abundance of water, the fool is thirsty" Bob Marley Link to comment Share on other sites More sharing options...

Watch the bass Posted September 26, 2013 Report Share Posted September 26, 2013 So I Might Not Even Need An ExtrA Battery? I would try first, to do a second batt if needed, is no problem (and no more monea than the batt and a vew feet 0/1 gauge) with your electricalsystem.

Agreene Posted September 26, 2013 Report Share Posted September 26, 2013 when you stated that you have 1/0 does this mean you did the big 3? deff need that to make sure the wire will allow the alternator to charge your system with max potential if anything the most you would need is another smaller battery in the trunk maybe an xs xp 950>?

Your 2500W of output would require roughly 3500W of power supply from the batts. Batteries of the 65 amp hour rating or higher can usually accomplish this. Check the rating of your current batt and upgrade from there. If your current batt is a wet cell, be careful when adding a 2nd batt to it as different chemistry batts reduce life when mixed together. Swapping your current batt for a larger batt that can supply over 3500W may be the best option. With your sized alt, Id say that you can go up to about 240 amp hours worth of batteries. So thats your range, 65-240 aH.

Bump4life Posted September 26, 2013 Report Share Posted September 26, 2013 See how your voltage holds now, if anything add a group 3400 size or larger in rear. Also be carful mixing bat types. if its a daily driver you should be fine. but it will reduce life of your AGM batteries if mixed with a wet cell and left sitting for extended periods of time. the newer AGMs will see the other wet cell batteries as a constant load since they rest at lower voltages than AGMs. Buyer/Seller Feedback Thread: http://www.stevemead...5015-bump4life/ MB C220 153 Trunk Car Build Log: http://www.stevemead...d/#entry1840136 MB C280 Ipad Dash SQ Build Log: http://www.stevemeadedesigns.com/board/topic/194484-bump4lifes-new-benz-tony-c-relay-kit-pictures-ce-electric-audison-front-stage-installed/ My SPL Log: http://www.stevemead...__fromsearch__1 BMW M340 xDrive Stock, for now.

vetkilr01 Posted September 26, 2013 Report Share Posted September 26, 2013 With a good alt...batt up front with that power should be all you need. Get a good batt, the biggest/highest ah you can fit and good for it. Link to comment Share on other sites More sharing options...
