3 deka batts or one crescendo?

[loudenuff]

I plan on dropping my amp to half ohm daily, which it claims stability in but I want to bump up my electrical a little first. I have a 275a singer alt, platinum agm under the hood, big 3, and I have one run of 0 to the back. plan on getting another though. so which would be better, 3 55ah deka or this Crescendo Logic HPL120 AGM PowerCell Battery - Crescendo Audio Factory Direct Online Store

boomsday's 155 amp hour batteries or the three 55 ah batteries.

how much is he asking for each?

AH is not nearly as important as people think. Also depends on whether you're running it at all with the car off. I would load test them and see what combo does the best above 11 volts. Deka's don't have a very high discharge rate but are perfectly good batts. If the Nendo tests anything like my d3100, I'd take the nendo over 3 of those g22 deka's.

Juice box 3100 or Duracell 3100 is what I'd spend my money on

The juicebox stuff is back ordered bad. Ive had guys get refunds from him and turn around a buy my batts. Boomsday is asking 220.shipped which is a good deal those things are massive

I've was EXTREMELY impressed with the load test on these: Exide g31 agm... and you if you go talk to a b&m dealer you may get a great deal on one. Exide has numerous batteries available for rebates this summer.

And the warranty is OUTSTANDING...

I don't plan on running with the car off. not for demo purposes, maybe for a hotbox every now n then lol I shot doomsday a pm for that Duracell. 100 pound battery sounds like my type haha, I got a run of 0 from a friend so I'll have 2 runs to the back, planning on redoing all of my wiring in the future with gp no b.s. 2/0 ofc. he has some sweet prices on that stuff

All of our Exide agm's slam on the ammeter lol. The replacement warranty makes it a no brainer, imo.

afaik all batteries are essentially made by the same 3 manufacturers anyway. but in this case: east penn = duracell = deka = quickstart (probably more I can't think of)

you'll probably get the dekas the cheapest, i bet you could get 3 of them for less than it'd cost for one of those crescendo batts (which are rebadged and marked up anyway)
