We found 6 Reddit comments about Battle Born LiFePO4 Deep Cycle Battery - 100Ah 12v with Built-in BMS - 3000-5000 Deep Cycle Rechargeable Battery - Perfect for RV/Camper, Marine, Overland/Van, and Off Grid Applications. Here are the top ones, ranked by their Reddit score.
BUILT-IN BMS: BMS stands for "Battery Management System" - the brain of our deep cycle lithium batteries. Our BMS protects your battery from most common causes of battery failure, such as temperature volatility or ground faults. The BMS regulates the amount of power taken out of the battery and acts as a shut-off system to protect the li-ion cells (and you) from unsafe operating conditions.LITHIUM ION TECHNOLOGY: Unlike Lead Acid batteries, Battle Born's deep cycle lithium ion batteries have unlimited mounting capability, exceptional longevity, and are more cost effective. When factoring time and cost into your purchase, our lithium ion battery banks come out ahead every time. Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults.GREEN ENERGY BATTERIES: Made from 100% safe, nontoxic, renewable energy, Battle Born Batteries last for more cycles and can be charged and discharged repeatedly (and charge faster than any other battery). We make our renewable, sustainable green energy batteries because they’re simply better than anything else out there, including other green batteries.LIGHTWEIGHT AND VERSATILE: At a sleek 31 lbs, our 100Ah 12v battery weighs in at only 1/3 the weight of lead acid batteries! With no acid in the battery, you're able to safely mount in any position. This makes li-ion batteries perfect for marine, RV, campers, golf cart, off-road and off-grid applications!BUY WITH CONFIDENCE: Proudly designed and assembled in the Reno, Nevada - the epicenter of the lithium ion battery world. We test (and re-test... and re-test again) literally every battery we ship and all of our batteries come with an industry-leading 10 year warranty. We believe you should be as confident in your battery as we are.
Awesome to hear another van dweller is in here! my current electrical design includes installing a two alternator system from nations and 4 100AH lithium batteries. That should give me enough power to run the speaker system, TV, Router and Modem and lighting for around 12 hours before needing to start the van and charge up the system. The automation is a total luxury, and adds the wow factor, but if implemented properly may be worth it to me. Budget isn't a huge issue, this will be the first house I ever build. My salary is pretty good and I'm spending $1500 a month to live here in southern california. Without the added rent expense I can justify making this thing an awesome place to live. Maybe a better idea would be adding a separate, solar electrical system with a 5th battery so that the wifi and automation system can stay on at all times.
I don't personally have one, but I've heard good things about the Battleborn batteries.
Contrary to what a lot of people say, as long as you don't abuse them Lithium batteries (especially lifepo4) are pretty safe.
If you want a single battery, get a 100ah lithium iron phosphate... its gonna cost you though...
AGM batteries are only useful for 50% of their advertised AH rating vs like 80%+ for Lifepo, also lifepo are lighter weight, and have more recharge cycles.
I run 2 of these right now to get 100 useful AH, and I am hopeful that in ~3 years when its time to get new batteries the cost of LifePo will have come down b/c they really are vastly superior in every way.
Depth of discharge.
I'm not sure how you get triple the cost for lithium, even if you can only buy from Amazon and only count up front cost. You're looking at 4x$170 lead batteries or 2x $500 lithium ones (in both cases the cheapest ones Amazon sells), which means $680 vs $1000. For triple the cost ($2040) you could buy name brand lithium instead (Battle Born or Renogy). And of course you're looking at 3000-5000 cycles to 90% DoD from the lithium rather than 300-500 to 50%... that extra zero really does affect the cost per cycle.
Here's a 'shopping list' for as light-weight a system that I can think of throwing together from 'off the shelf' components:
>Solar Panels:
Two of these will give you a light-weight solution for 400 watts of power!
https://www.amazon.com/Dokio-Monocrystalline-foldable-Inverter-Controller/dp/B075SZMFP2/
>Charge Controller:
The included controller won't be terribly useful I'm afraid, because it's for Lead Acid, and is a crappy PWM controller anyways. So, let's assume you're going to DIY this a bit and build a weatherproof box for your battery and a controller like this one:
https://www.amazon.com/Solar-Controller-Monitor-Temp-Sensor-Package/dp/B06XNP1BGR/
>Batteries:
Here's where you drop the real cash; At least one but preferably TWO of these guys.
https://www.amazon.com/LiFePO4-volt-Deep-Cycle-Battery/dp/B06XX197GJ/
>Inverter:
If you'll be needing AC power, you'll want something like this:
www.amazon.com/AIMS-Power-Watt-Inverter-Cables/dp/B002AMPHHC/
>Container of sorts:
You'll be needing something weatherproof for all this non-weatherproof stuff to sit inside. Find the 'weatherproof storage lockers' at sporting goods stores, and you can machine them to be what you need for stuff like this. It'll need to fit your batteries, inverter, and charge controller, and you'll need to mount them in there somehow so it doesn't bounce around. Then all you need is some slick weatherproof electrical connectors to mount going through the wall of the box, and you've got yourself a great system. You can even put in things like a 12 socket and weatherproof volt meter to keep an eye on your battery voltage.
Overall, this would cost probably around $3000. But, it'd work well. :)
If you can give me more specs on what sort of weight you can carry, you could have the option of switching to Lead Acid as a battery type; but that would add like 150 pounds of weight to this whole setup, but you'd save $1500 or there about on the batteries, and you COULD use the included cheap PWM controllers... but honestly that MPPT I think would be worth the extra cash.
The comparable product (excluding the panels, and assuming you only got one battery) would be the Goal Zero Yeti 1400 Lithium. It's $1700 and is about the same thing, again excluding the panels.
Honestly, for your purposes, the Goal Zero Yeti looks pretty good if you're not really into the DIY stuff; cause you'd be looking at $1700 plus $500 for the 400 watts of panels, so $2200 total. That's not bad! (Assuming you DIY it like I'm suggesting, and only use one battery, you're looking at around $2000. So, really, not much cheaper if the weight matters to you.)
Glad the info helped! Let's say you're using 100 watts (Xbox with TV). It sounds like you may be using only 90 watts, but we want to allow for electrical inefficiencies so we add 10% to your usage, so in this case that's 99 watts. Let's say 100 watts for simplicity and for a little extra margin.
The GoalZero website says their battery has 280.8 amp hours (Ah). You don't want to discharge a lithium battery more than 90%, so your real capacity is 252.7 Ah (280.8 * 0.9). Your system uses 8.34 amps (100 watts / 12 volts = 8.34 amps). To find out how many hours you can power your system on this, divide your Ah by amps, so 252.7Ah / 8.34A = 30.3 hours...which means your math is correct :) Keep in mind that it will take around 9 hours to recharge this battery.
A little more math: You can get a 100Ah lithium battery for $950, a 600 watt pure sine inverter for $220, and a lithium battery charger for $175. Throw in $20 for cabling and you're up to $1,365, so let's say $1,400 if there's any extra shipping. That's less than half the cost of the GoalZero and you'd get 10.8 hours of play from it, and recharge time would be 3.3 hours.
If you get two batteries, your numbers would be $2,315, 21.6 hours of use, with a recharge time of 6.6 hours.
I'm not saying you shouldn't get the GoalZero since it may be the perfect solution for your needs. Just trying to show you other possible choices.
