Nate Futuristic Posted May 30, 2012 Report Share Posted May 30, 2012 (edited) this may have already been answered i searched for a good 20 mins to find the best answer to my question and only came up with this: any xs power batteries mixed with non xs power batteries can deplete overall lifetime and performance of the xs power batteries! so here is my problem lol... i have 3 brand new d975s that are going in the back of my truck for a "midget battery bank" and i have a (N)ever start 700 maxx upfront (bought it from a friend when my optima started resting @ 11.8 ) im at the point of my build that i need to run the 1/0 and get the battery bank hooked up but i really dont want to "mix" them with that shitty flooded upfront! i plan on ordering a d925 for upfront tonight or tomorrow and it should be here by next week sometime. so my question is.............................................. if i hook up the back batteries to the front for lets say no longer than a week could i cause any serious problems to the D975s? or am i better off waiting the week or so till the d925 comes? the only reason i ask is i dont have my 4 channel hooked up and driving around with no music at all is kill me any help would be greatly appreciated!

HunterJohnson Posted May 30, 2012 Report Share Posted May 30, 2012 Im pretty sure its the other way around. the amg batteries bring down the wet battery Quote Scion tC SQ BuildiPad mini, lots of fabrication, daily drivenFord Explorer C Pillar Wall Build Just a cheap car to destroy with bass Link to comment Share on other sites More sharing options...
ALAMO695 Posted May 30, 2012 Report Share Posted May 30, 2012 (edited) Im pretty sure its the other way around. the amg batteries bring down the wet battery the agm batts usually rest higher than wetcells, therefore if you connect the agm with the wetcells, the wetcell will think that the agm is some type of charge and bring down the voltage of the agm to where they will "even out".edit causing the agm (if it rest bellow 12.6v) to develop sulfation on the cells, making that part of the cell pretty much dead.

Tebo Posted May 30, 2012 Report Share Posted May 30, 2012 (edited) no the wet cell will kill the agm, happened to me shits no fun. Just wait a week dude. OR make a small buss bar where ever your 0ga is running and hook your 4 channel up to that.

Nate Futuristic Posted May 30, 2012 Author Report Share Posted May 30, 2012 Im pretty sure its the other way around. the amg batteries bring down the wet battery HAHAH really? i assumed it would cause problems with the d975s because from my understanding the batteries that have the highest resting voltage (my d975s rest @ 12.7x NEW never charged and my flooded rests at like 12.3 or some crap) will be drained by the battery with the lower voltage... im just wondering if a week is a long enough time to cause damage Quote down rpping vanderbilt. 30 miles from victoria. i own the 3rd loudest setup here out of 3. but i did put together all 3 setups ^^ Cant wait to swalllow Ghost's babies Link to comment Share on other sites More sharing options...
ALAMO695 Posted May 30, 2012 Report Share Posted May 30, 2012 just eliminate the wetcell completely and run the 0g from the back batteries to the front terminal. You will then basically start your car from the rear battery bank. Quote Link to comment Share on other sites More sharing options...
Nate Futuristic Posted May 30, 2012 Author Report Share Posted May 30, 2012 i was thinking for the week or so shipping time ill just put one of the d975s upfront and have the other two in the back.... im still REALLY REALLY nervous to put a xs power battery under the hood because the radiator is RIGHT next to the factory battery location..... might have to buy one of those cases they sell for it to "so much money and time spent making copper windings move up and down a magnetic pole" Quote down rpping vanderbilt. 30 miles from victoria. i own the 3rd loudest setup here out of 3. but i did put together all 3 setups ^^ Cant wait to swalllow Ghost's babies Link to comment Share on other sites More sharing options...

Bump4life Posted June 1, 2012 Report Share Posted June 1, 2012 so what is the verdict. does using a flooded (stock) battery and an XS AGM or other bat togehter hurt the AGM bat or the flooded stock bat? and is it ok to combine and use both at once?
