Hi i have a quick question can a pure sinewave inverter be attached to a battery that is being charged by a gas generator i want to use a life poe 4 40 amp or more battery charger for when their is no sun for several days to charge my batteries as a backup or could i plug the charger drectly...

Awesome ty my charger does hold at that voltage when it is done my charger is a smart suoki 4 amp charger from Amazon quick question is a battery charger and battery maintainer the same thing would a maintainer be better if it's not a charger for keeping them charged for backup? I really...

Okay well I do want to protect them while in storage how do I hold them at the float voltage standby voltage? Would that mean I leave them hooked up to the battery charger constant? Also when I say percent I mean volts which I've already stated when my volt/ohm meter says 12.66 volts I looked...

Remember I said that it's charged with a smart charger that being said it's charged at 14.8 volts after it's full it'll be at 13.8% standard use or standalone the charger will say full at 13.8 so then I disconnected so I know it's being charged correctly all I am trying to find out is why a...

Ok ty attaching a picture of my battery so basically all I'm doing is charging my battery up with a battery charger that is a smart battery charger it shows the amps in and out and the voltage when it says full the battery is at 13.8%. after 1 hour after it's done charging and I have removed the...

Hi I have a question for those experts out there concerning charging your AGM or SLA battery I have 2 mighty Max 12 volt 15 amp hour batteries I charge them with a 4 amp suoki battery charger I use the SLA setting as I believe thats what the batteries are but I've been told SLA and agms pretty...

Ty yeah Amazon's got a good deal for 4-hqsts and I have a renogy panel already the old 100-d the panels are not a problem they're actually pretty good for the price it's just finding a well-rounded Mppt that doesn't break the bank lol

Thank you but as you can see this is the whole reason I want to just do AGM any one of the mppt's renogy hqst etc epevers all of those are great with agms no problems so that's why I'm seriously considering just doing an AGM battery bank and charging my lithiums off of that it would really be...

Ty 12voltinstalls so then I guess your saying the custom settings on the renogy and hqst and other of the more economical mppts are not that hard to configure on custom therefore just use a lithium batteriy to charge the others instead of two Agms which would be more practical in the long run...

Yea Amazon's got a hole section devoted to reneogys 40 amp mppt how terrible it is with lithium and the Bluetooth module and also a lot of the popular others that's why I'm thinking about just a simple way to keep the agms charged and only use them when I need them and since I'm only going to be...

Awesome bud ty! I needed that math on the watts I can hook the solar directly to the lithium battery threw the mppt normal just click lithium setting but I don't want to risk it because I hear so many bad reports on these mppts that they don't shut off and they do the float charges wrong and a...

Basically I'm just trying to have a recharge station for my lithium batteries if say a hurricane hits us and we're without power for several months or the grid goes down and yes lithium has low self discharge which I love but eventually they're going to have to be charged in a scenario like that...

hi i was thinking about getting one of the renogy 400 watt kits or hqst with a bougerv 40 amp mppt with fuses etc and having it set ready for any longterm powwer outtage or hurricanes hooked to 2 agm 100 amp batteries when i need to hook it up.Here is my question i just wanted to use the agm...

Ty pierre that's a good idea I'm looking into that too it's just I don't have half the knowledge you guys have I sure wish I did so I'm actually researching that as we speak I work nights as a security guard and in fact I'm just getting ready to clock out and go to bed that'll be researching...

The fridge I have will run 9.2 amp hours or 120wh in a 24 hour period I believe on economy mode or just straight the reason I need that regulated supply is because without it most batteries will shut off the fridge because it's showing low voltage usually around at 50% without the regulated...

Thanks Mike but I'm not planning on using the vehicle I bought the fridge is back up in case of a hurricane I live in Brownsville Texas right on the tip South Padre island baby so if we get hit and I'm without power for a couple of weeks or a month or so I need to have some way to have a battery...

Ty! I do have the Anderson power pole connectors and the ratchet I bought from powererx for my shortwave radios and scanners so that way I could use it to wire with the West mountain radio rig runners and such I'm thinking I could combine your idea with Bud's idea and make my own regulated DC 12...

Thank you bud didn't know about tripping the battery that's why I love getting all the info from you experts I really do appreciate it ? and thank you for the Amazon link!!

Here's a guy who made one for his solar generator I just wanted to make one to hook up to a direct 100 amp battery but the load on the receptacles I think can only take 10 amps here's another video to help you all understand the power pole would be nice but there's no way for me to go ahead and...

here's the link regardless of the refrigerator there are a lot of items that need to be run off a 12 volt regulated receptacle I call them cigarette lighter receptacles there might be called a different term so refrigerator or not I need a regulated receptacle that is exactly like in the solar...

It's a bouge 12 volt rv type fridge(you can find it on hobotech on you tube) It runs about 9 amp hours or 120 kw for a 24 hour period so any solar generator that's 300 watts on up can power it for several days especially if it's 500 watts or more the thing is they cost an arm and a leg and I...

Hi I'm trying to make a 12 volt regulated DC power supply cigarette Jack for a 12 volt refrigerator to run off lead acid batteries or maybe even lithium but I can't seem to find any inverters that have those in them so I was wondering do I need to buy a 12 volt regulator off Amazon and then just...

I have a Ub 12100 12 volt 100 amp and a couple of mighty Max 12 volt 15 amps and I was thinking about getting a couple other ub 100 amps so those would be the batteries I've contacted the company to get the specs but for some reason they don't seem to have a DOD chart or any of the info I need...

I'm sorry that's for wet batteries I'm curious about SLA and AGM

Yes lol btw I hear these charts are not accurate what is your opinion because they don't factor in when you're bearing a load so how do you know when to cut it off to charge?

Ty!

Ty I was wanting to set up a system for hurricane season that runs down here from June to November to have backup power for essential items I really appreciate the info offhand do you know is it the same for lithium ion batteries will high temperatures outside affect them?

hi im starting a 400 watt solar system maybe up to 800 and i have a question about lead acid batteries i live in brownsville texas AWESOME SUN but daily around 95 or more degress i know if its cold batteries are hard to charge but say i have a setup 200-400 amp battery bank in parralel to keep...
