Hi, thanks for reaching out! You can get in touch with Carlos Cauton (C.Cauton@BigBattery.com) by email and he'd be happy to discuss pricing and availability with you.

I think it's just his cart not like his business or something

Hi, thanks for your question. We were averaging around 18 - 22 mph throughout the range test. Typically, stock golf carts see top speeds between 15 - 20 mph, so we wanted to make sure we stayed around that range in order to see a true comparison of the range benefits of switching to lithium. Feel free to check out our 48V HUSKY 2 kits right here (bigbattery.com/golf-carts/) and give us a call at (818) 280-3091 if you have any questions!

Hi, thanks for your question. These systems would be installed and operated very similarly in a truck or tow-behind trailer. As long as your trailer's battery compartment is large enough to support the installation of your desired lithium system, you would simply be replacing the auxiliary power system with your new BigBattery set up, similar to what you see in the video. We have a wide range of kits at different capacities and voltages so however big or small your system needs to be, we can set you up with a tailored solution specifically for your trailer. Feel free to give us a call at (818) 280-3091, or send us an email at Sales@BigBattery.com, and a member of our team here can discuss your current set up in-depth and offer a personalized recommendation for you!

Hi Curt, thanks for your question! Unfortunately, lead-acid meters won't read accurately for lithium batteries. We always recommend using the capacity meter that comes with our battery kits since these meters have been specifically calibrated for our batteries' chemistry and voltage curve.

Hi Greg, thanks for reaching out! We're sorry to hear about any issues you're experiencing with your batteries. There could be a couple factors at play that might cause draining of the battery overnight. Give us a call at (818) 280-3091, or send us an email to Support@BigBattery.com, and a member of our Support Team can go over the issue in-depth and troubleshoot with you.

Hi, thanks for your question! To clarify so we can point you in the right direction, you're looking to understand how to connect an ETHOS stack to an existing AC-coupled system?

@@BigBattery I have SunPower panels. They all have mini inverters. That means that the power coming from my roof is AC. I am asking how your inverter deals with incoming AC.? It seems to me that it would need to be converted back to DC to charge ethos batteries. Then back to AC to power my home and the grid. I would lose some power in all 3 conversions. Please tell me if I’m wrong. Or tell me of an advantage that I am not seeing. I live in the southern ca high desert and air conditioning is a top priority I’m slowly changing out all propane equipment for heat pump or electric when heat pump is not available. I like your ethos battery backup mostly because I can start with 3 bricks and add on when needed. I like the small jump in storage at a reasonable price. Powerwalls cost a lot more if you need more than one but 2 is over kill.

​@@Skookman Thanks for the clarification! We hear you about the hassle and cost of upgrading your power when it comes to other single-unit options. The stackable, expandable design of the ETHOS is a great for an initial home system. To your question, the 12K Lux inverter(s) that's paired with our ETHOS Systems can absolutely handle any incoming AC power from your panels. These inverters feature both a standard grid connection port, as well as a second port specifically for external AC sources such as a generator or your solar panels. In regards to power loss during conversion, there will always be some nominal amount of loss during transfer for every inverter on the market, but with high efficiency conversion and fast transfer times, that loss becomes negligible. The 12K inverter we offer has a transfer time of 20 ms or less, with 95% - 99.9% efficiency so you shouldn't experience any noticeable loss of power between conversions. Plus, these inverters allow you to set timeframes where your solar panels are feeding directly to your home appliances, bypassing the battery and reducing conversion steps. Feel free to give us a call at (818) 280-3091, or send us an email to Sales@BigBattery.com, and one of our team members here can go over your current system in-depth and offer a personalized recommendation for your power needs!

Hi, thanks for your question! You absolutely can. There should be no issue with leaving the batteries on when not in use. While shutting them down overnight can prevent self-discharging, this discharge rate is very nominal and shouldn't be noticeable when returning in the morning. Plus, our HUSKY 2s feature a Standby Mode, so if they don't detect a current after a while, they enter Standby and reactivate once a current is detected. Feel free to give us a call at (818) 280-3091 if you have any additional questions. Thanks!

Hi, thanks for your question! Many of our customers do use the ETHOS for emergency backup power. However, some homeowners also use the ETHOS to offset the cost of their monthly electric bill, and some even get rewarded each month by giving excess power back to the grid through incentive programs and tax credits, covering the total cost of their system in as little as 2 years! Some serious power enthusiasts have even taken their entire home off-grid with our ETHOS Systems. Generally, our base 10.2kWh ETHOS System can support the average 2 - 3 bedroom for a day should the power go out, but if you avoid using non-essential appliances and reduce power consumption, that can improve to 2 or 3 days. Keep in mind, there are a lot factors involved in determining the size of your home's power system, but since the ETHOS is stackable and modular, you can easily expand upon your system later on as needed. Feel free to give us a call at (818) 280-3091, or send us an email to Sales@BigBattery.com, and one of our team members here can go over your current usage and offer a personalized recommendation for your power needs!

@BigBattery thanks for the info but 8 grand for the cheapest is still wayyy more expensive than a generac especially where i live. But thanks anyway, have a good one.

​@@kratos7893 you can pay off the system in 4.5 years. After that no bills. Electric bill will not be the same in 5 years. Will it be $600 or more a month in 10 years? Probably.

Hi, thanks for your question! As long as your cart is on the smaller side (4 or fewer passengers, no cargo bed with heavy loads, etc.) than one HUSKY 2 should be more than sufficient. However, if you have a larger cart, or find yourself going through harsh driving environments or frequently carrying a lot of weight, than we would recommend going with 2 or more batteries to ensure you never find yourself low on the power throughout the day. Feel free to reach out to our Sales & Support Team at (818) 280-3091, or by email at Sales@BigBattery.com, and one of our team members can discuss your cart more in-depth and make a personalized recommendation for you! You can also see all of our golf cart kits right here: bigbattery.com/golf-carts/

Hi, thanks for your question! Our ETHOS is compatible with a wide range of inverters including Enphase. However, in order to capitalize on AC coupling and receive UL9540a-certified permits, you'll need to use the ETHOS with our paired LUX inverter. Keep in mind though that exceptions can be made and we recommend reaching out to your local/regional AHJ to see if your system qualifies. Also, feel free to reach out to us at (818) 280-3091, or send us an email at Sales@BigBattery.com, and one of our team members here can discuss your current setup more in-depth and determine how to get the most out of your power system!

Yup! You can even keep adding additional modules for more power!

Hey please reach out to our team! Call (818) 280-3091

Awesome to hear! We’re here for you if you need anything, anytime 🔋

Yea Bro! You should hear it in our Golf Cart powered by the Husky 2! : )

Lithium batteries are currently being transitioned out of favor. But they are still the highest performers on the market. But like i said, there are dozens of alternatives currently working their way through the manufacturing process

Hi Robert, At BigBattery, we're proud to source our lithium domestically from the USA, which constitutes less than 1-2% of our batteries. We use Lithium Iron Phosphate (LFP) technology, relying on abundant and locally accessible elements like iron and phosphate. When your battery reaches the end of its long lifespan (15-21 years), we offer free recycling services to ensure environmentally responsible disposal. Excitingly, within the next two years, we plan to introduce Sodium-ion batteries, predominantly made from table salt, carbon, iron, and phosphorus. Our commitment to sustainability means we avoid conflict materials, focus on local resources, and design our batteries for easy repair and recycling. Thank you for engaging with us!

Nothing is without flaw. Batteries arent a perfect solution, as they are today, but battery technology advanced as demand and funding increases. Like all advancements in technology. Our current dominant sources of energy have had their chance to reinvest in their own efficiency and have failed. Gasoline is still only 35% efficient Coal is only 40% efficient Natural gas is less than 30% efficient There is plenty of room to extract more energy and produce better engines But they havent So now a new form of competition has emerged, and yeah its environmental promises are effectively lies, because the type of pollution is different, green house emissions are lower, but water pollution and other hazardous toxins are byproducts. But even that will change over time Short term, yeah its trading bad for different bad Long term, it is a net benefit for the environment and economics

Someone eliminates reliance on the grid, avoids peak energy charges, stores power to prevent a blackout, and can sell energy back to the grid… Yet you have something negative to say?

With all due respect Lunchbox90, LFP batteries are indeed cleaner and better for the environment than NMC batteries. They use abundant, locally sourced materials in the USA, avoiding harmful heavy metals like cobalt, which is often mined in conflict zones with severe human rights abuses. LFP batteries also have a longer lifespan of up to 6,000 cycles compared to 4,000 for NMC and are fully recyclable, significantly reducing environmental impact and reliance on conflict minerals. Additionally, using solar and LFP batteries is a more environmentally friendly solution compared to power companies burning coal or natural gas in Peaker power plants. Nature has been powered by a massive fusion reactor 93 million miles away from earth long before we got here.. We prefer harnessing that energy for mankind. Thank you for your input.

Hi Josh, thanks for your question. Since the meter is powered by the batteries, as long as the batteries are on, the meter will be on as well. However, the power usage from the meter is less than 1mA so any additional draw from the meter should be negligible. Feel free to reach out to us at (818) 280-3091 if you have any other questions or concerns!

Appreciate your support - we'll keep making more videos to help share our new products. : )

Hi, thanks for your question! Our 24V HUSKY 2 comes in at 95 lbs with a 5.12kWh (200 Ah) capacity. You can see this battery and our other HUSKY 2 Kits on our RV/Van page here: bigbattery.com/rv/

Hi, thanks for your question, and we feel your pain! All that watering and maintenance just for an hour of runtime is unsustainable for food truck businesses. We have a few all-in-one systems for food trucks that have revolutionized how business owners power their trucks and afforded them massive lifetime savings. If you're looking for a similar 15kWh system in 24V, feel free to check out our 24V HUSKY 2 Victron Kit here (bigbattery.com/products/24v-3x-husky-2-kit-victron/) These kits have been some of our best sellers so they're currently on backorder until June 7th, but we have plenty of upgrade options for commercial vehicles on our RV/Van page if you need something sooner (bigbattery.com/rv/). Our 24V kits can range from $2,350 - $9,450 depending on system capacity and type of charger or inverter, but no matter what kit you choose, our lithium batteries afford charge times up to 4x times faster than equivalent lead acid options, and require zero routine maintenance. If you have any questions, feel free to give us a call at (818) 280-3091, or send us an email to Sales@BigBattery.com, and one of our team members here can discuss your current setup in depth and find the ideal system for your truck!

What a stupid thing to comment about the fifth largest economy on earth.

39,100,000 People live in California. It is the most populous state in the USA with Texas coming in as #2. Fortunately - we are establishing a 310,000/SF manufacturing facility outside of Dallas TX. That's the beauty of America - You can live where you want and follow your dreams! Thank you for your comment.

Our ETHOS currently starts at $8,940 for the 2-module 10.2KWH system. Keep in mind that we are currently the best-priced UL Certified stackable system in the United States, which we are very excited to share!

Hi, thanks for your question! Since lithium batteries are a fraction of the weight of lead-acid options, those counterweight boxes are necessary in order to keep the overall weight consistent with the original certification for the vehicle and ensure your scissor lift is still operating properly and within safe parameters.
