Lanzar_Optidrive Posted February 23, 2015 Report Share Posted February 23, 2015 Howsit Guys I just wanted to find out if 6v 250 amp hour cells are good to use for car audio? I plan on networking 2 6v in series to make 12V .....and then run 3 sets of those 12V ( 2 x 6V in series) in parallel to step up the current. What are you takes on 6V cells?

redwolf2 Posted February 23, 2015 Report Share Posted February 23, 2015 For every 2 you would only have 250ah. They don't scale the way you're thinking of. So I must ask....

alaskanzx5 Posted February 23, 2015 Report Share Posted February 23, 2015 Would most likely get better/nite answered in the electrical section. Interested in the answers though. The way I see it 3 sets of 2 would give a 12v storage with a good ah. What would the discharge and recharge rate look like though? t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

magillaru Posted February 23, 2015 Report Share Posted February 23, 2015 Pretty sure you'd have to wire in series to make 12 volt but don't quote me on this...... You can use them..... But wait for confirmation on wiring from someone else who chimes in though. Singer Alternators Team Asshole #anothershittysingerbuild Link to comment Share on other sites More sharing options...
alaskanzx5 Posted February 24, 2015 Report Share Posted February 24, 2015 Yeah it would be 2 in series to make it a 12v battery (max charging voltage reading voltage would be unknown???). Then 3 sets of those wired in parallel. Gives a total of 3 12v batteries. Imo with the limited info on doing this for car audio and the work it would take plus the space it would use up isn't worth it. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

Broke_Audio_Addict Posted February 24, 2015 Report Share Posted February 24, 2015 Dude around here use to run a 18 volt setup with a trunk full of 9v volt Batts back in the day. Should specify they were big 9 volt batts not the little guys. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Lanzar_Optidrive Posted February 24, 2015 Author Report Share Posted February 24, 2015 Hi Guys These 6V cells are not that big as compared to my 12v that i have but they are almost equal in weight.... 12v were 63kg each and these 6v are 30kg = 60kg to make a 12v bank..... so its a loss of 3 kg per set also the 6v are newer also remember the 6V are 250 amp hour batteries at 6V - the CCA on them are 5000 each at 6V so when i series two - wont i get a longer time burst of 250 amp? the bank becomes bigger so in total im looking at 750 amp hours with 15000 CCA Link to comment Share on other sites More sharing options...
Lanzar_Optidrive Posted February 24, 2015 Author Report Share Posted February 24, 2015 someone told me that they were not good for sound... but batteries are made up of cells... but the guy said i must get 2v cells.. so now the doubt so decided to ask the experts Link to comment Share on other sites More sharing options...
alaskanzx5 Posted February 24, 2015 Report Share Posted February 24, 2015 The way I understand it Amp hours divide by 2 when 2 are ran in series So 125 per 2 (12v bank) So 3 12v banks gives you 375 amps. Say those 6v batts rest at 6.2 volts, gives you 12.4 resting voltage power back. Typical agm battery is 12.6-12.8. Losing some voltage. Them you have to consider internal resistance of each battery and all 3 banks as a hole. How high can you charge them? 13? 13.8? 14.7? 15.6? How fast do they discharge and recharge? How long can they do this before going out? Lots of other stats to look into. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
