I ask because I was going to have 2 120amp alts in my car and was thinking maybe a batcap would be better then extra batteries overall (weightIf you have dual 120a alts, how many watts RMS are you running? If you are running that type of alts, then you probably need much more than one small Batcap.
Are Batcaps flooded or AGM?That's a good find
Lol, this thing is massive

They are all AGM.
Gel-Cel = FTL
Yeah that is a big *****. I run 4 of the above with a kinetik 1800 in the trunk, for a total of 5 batteries and an Optima up front. MA HK 4000d at full tilt does not drop below 14v
If it does not drop below 14v, you are running 100% off your alt. Your batteries are there for nothing more than starting your car.
From what I understand about batteries that if you use small batteries that have less lead in them on a bigger system draw, you are cycling the smaller battery more than you would be the larger battery with more lead. The more you deep cycle a battery the more the lead gets depleted from the plates. What might be grand for a magic 4 seconds in the lanes might not hold up as well as a larger battery year after year of daily or competition use.
That is true about using too small of batteries. Usually, any thick plate AGM should hold up for at least 500 deep cycles. The thinner plate models (Optima) will not be able to do so. The thinner the plates, the shorter the lifespan. However, thinner plates are what give you higher amperage outputs. So you have a trade-off there.
Hummm did anyone check out the other batteries they have for sale. Looks good for the prices. I wounder how well built they are. Even have gel cell batts and AGM ones too.
Like I said above, Gel-Cel=FTL //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
