3 aa batteries barely charge a flashlight for 10 hrs ya tweaker. Wtf math are you doing? It’s not anything from this planet...

This is why I told him he needs to learn about Amp Hours. He's very clearly not factoring in the hourly consumption at that power factor...or the fact that AA batteries have never been designed to output that kind of power. The fact that the OP didn't start thinking about using deep cell batteries, when I brought them up, leads me to believe this dude is just a troll.

Hi i found these light strips i have 8 ish square feet grow 2m by 2m ish 1.5m tall
6-10plants and no plug totally off grid i am going to wire these to batteries with a timer and i was wondering how many meters of this i should buy or if i should buy this

The sun is pretty powerful and an off grid favorite.

He isn't factoring in potential voltage drop either.

I actually have a battery pack that could run some lights for awhile and I can tell you that those sad, underpowered strips and some AAs ain't going to do shit. Each cell in these packs has a maximum continuous output of well over 100 amps, 10 ah battery life and are 3.2 volts nominal. It is currently configured as 16s4p for a total output of 48v, 480 amps peak output and 40 ah. This is a nasty powerful little pack and I still wouldn't be able to run a grow room for very long on a charge. OP is either a troll, or hopelessly uninformed on the subject.

They work great in a small grow space where they are close to the plants, and surround all sides of the plant, like in a space bucket grow. But you are talking about 2M x 2M, which BTW is 42.25 square feet (not 8 ), and that is a completely different ball game. For that type of square footage, and that type of LED, you would need more than 2,500W of LED. Sounds like you need to do a lot more research.

I have been gone for 2 hours and every1 has seen this post and thought i was an idiot well peoble these calculations are wrong i dont need 2500w i need 693 w he forgot to take the sq.ft. and divide it by 4. This will give you the square foot of an individual plant, which is vital in figuring out the right wattage you need over your plants 2m×2m is 43.05 sqaure feet not 42 sqaure feet and 693w i i am only going to have 6 plants so i wont need more than 600w need 150ish batteries to power that from 10 different led strips per 70 days i haven't decided which strip to pick so i dont have exact numbers so its 150ish batteries but even 200+ batteries are okay they are cheap in bulk so np and i am disgusted that peoble took 1 look didn't even read and dare to call me stubid meth/heroin/idiot and more after barely reading and i hope u peoble that posted that shit read before they start throwing those terms around and yes i made a mistake with sqaure footage calculations but i had the watts spot on and i have been growing for 2 years and have done alot of research thnx for all that tried to help me

I have looked for hours for a battery like this tell me more but yes it would work i have seen peoble making it work online it would decrease yields alot but my elictrician friend said that no battery would be powerfull enough to power 700w charged every 12 hours unless i had 3000$

set a stationary bike up to a little generator and battery packs and pedal until its charged. you will get a good work out by the time you harvest.

Or get the wife to do it. Tv with some cake show or whatever and you're good to go.

Growing is my hobby i am good at it i grow qaulity weed but i have moved i have no space so i have to take move my plants off grid which will hurt yields but i can live with that

My pack is built with headway 38120hp cells. 64 of them. I believe my total cost for the batteries was about $1000 plus another couple hundred for the battery management system (BMS). If you configured the pack for 54 volts rather than 48 and had a decent BMS you may be able to set it up to run a few hundred watts of strips or quantum boards, but you'd still need a way to charge the pack. With a 40 ah pack like mine you might get a couple days of light before charging but you have to consider other needs like fans. Either way its going to be a big investment.

P.s. my pack is designed to output 4800 watts to an electric motor, but under that kind of load it's only good for a few hours of use. If you kept the draw around let's say 500 watts you'd get quite a bit more .
