Just starting to assemble my setup, and have been researching batteries. Seems that a marine deep cycle is the way to go, and group 29 or higher? At least that’s how i understand it.
My pump is currently a Seaflo 5.5 GPM 60 PSI, but will probably get a bigger pump eventually… like a 7gpm or fatboy or whatever they are called.
Is this battery ok? Everstart Marine Group 29 885 MCA - $100
Yay, nay? Less expensive quality option anywhere?
Go with a AGM marine battery. Batteries plus has good price on. Just tell them you need for a trolling motor. Got mine from Sam’s club for about $100. It’s 1/2 the size and weight. One you’re looking at weighs 61 lbs. Got one like that and never use. It’s worth the extra money to get the AGM
61 lbs! Holy moly, didnt even think to look at that.
Matter of fact, i had wanted to get one like the one in your video, but i couldn’t make out the model number. Going back to the video, i can see that it says 775 cca (i think).
Searching on Sams website for AGM marine with cca 775 turns up this group 34 for $120.
Guess i will go for that, unless there is a better option.
Thanks for the help!
Collect all the old batteries you can. Usually battery shops will give u a $10 per old battery, to put toward your new battery.
I looked up the pump that you were using. I noticed that it’s an rv/marine/etc pump. Is that really any different than say this? Other than the gpm and it’s no delavan, just curious.
Out of curiosity. Whats battery life for these set ups? And do u just trickle charge it the evening before you need it?
In general they are the same type of pump. I looked up the one you have there… i showed it at $210 for a 4GPM. Buy the ones at pressure tek instead, they are what most people use. The 5.5GPM is around $130.
Yes, most people just hook them up to a battery tender at the end of the day. 1 good marine deep cell should stay strong for the day, unless you are on the trigger constantly. Some high volume guys might use two batteries.
We’ll the reason I ask is that the one shown was on Craigslist listed for $60, supposedly never used.
Depends on what you’re going to do with it. At moderate pressure you’re only going to get about 2gpm flow out of that. Plus need to see what kind of seals it has. Got to be chemical resistant. Go with a NT, delavan or versa jet 6gpm from pws. NT has a 5.5 for $139 that works pretty darn well plus cheap warranty.
If you’re just doing an occasional small roof, one battery should last you all day. The problem is that as they get a little weaker, can cost you some distance. I run 2 in parallel
Have any of you ever considered running two pumps in parallel??? Then they could go upstream of the mixing system and push, instead of pulling from downstream. One on SH, one on water, maybe soap would get pulled in like with downstreaming? Lol. Maybe not I guess.
People have tried everything with these 12v
