Product FAQs

BigBattery Frequently Ask Questions

Q1. Can your batteries be used in series?

A1. We no longer offer our batteries for use in series.

Q2. Do your batteries have a thermal management system?

A2. All of our batteries have a thermal management system that is controlled by the BMS (Battery Management System). This Thermal management system will not only prevent the battery from being used if the temperature is too high, but also if the temperature is also too low.

Q3. Can I use my OEM charger?

A3. No. Lead acid battery chargers charge at different currents and voltages than our lithium batteries. Using your OEM charger can damage your battery cells and void your battery’s 10 year warranty. We have several chargers optimized for and calibrated to every battery we sell.

Q4. Why does the voltage drop when unplugging the charger?

A4. The voltage drop that you experienced is called the “bubble voltage” and is perfectly normal for Lithium Batteries. LiFePO4 batteries behave differently than other battery chemistries. The Voltage vs Capacity is not linear. For example, if you have a voltage between (13.3 – 14.6) or (26.6 – 29.2) or (53.6 – 58.4) you will have more than 99% of the capacity. This essentially means that “Bubble Voltage” contains less than 1% of the entire capacity and the drop when a load is placed is instant.

Q5. Can I leave my batteries outside?

A5. No. Our batteries are not marine rated or weather proof, so leaving them out under the sun all day or in the rain can damage the batteries. (This type of damage is not covered under the 10 year warranty.

Q6. How many years will my battery last?

A6. Lithium Iron Phosphate (LifePO4) batteries can be cycled from 3000 to 7000 times. If you cycle the battery daily with an 80% DoD (Depth of Discharge), then you can get even more than 10 years of use from your battery.

Q7. How do I install my battery?

A7. All of our batteries come with free ring terminals that can be used to connect your battery to your inverter, cart, or busbar system. We also sell a parallel busbar that can be used in tandem with the included ring terminals to parallel multiple batteries.

Q8. What is the difference between the 12 A and the Upgraded Charger?

A8.

Upgraded Charger:

Charging Current: 15A
Input Voltage: 110V / 220V
Output Voltage: 58.8v
Charging Time: 5 h (approx)
On-Board Charger: Yes
Protection: IP65

12A Charger:

Charging Current: 12A
Input Voltage: 110 / 22V
Output Voltage: 45V,50.4V,58.8V
Charging Time: 6.5 h (approx)
On-Board Charger: No
Protection: IP50

Q9. Doe Big Battery sell used/surplus batteries?

A9. In the past Big Battery sold refurbished batteries, such as solar batteries made from recertified Nissan Leaf modules. As of the year 2020, all batteries sold are new, never-previously-cycled batteries that come with a complimentary 10 year warranty.

Q10. Do you ship outside of the United States of America?

A10. We only ship within the continental United States. All shipping is done via ground shipping methods. We recommend looking into a freight forwarder to receive shipments outside of the continental United States of America.

Great MID from EG4

I recently installed the EG4 GridBoss along with the EG4 18KPV inverter and EG4 wall-mounted batteries, and I’m very impressed with the entire setup. The integration between all the components was seamless, and the system has been running reliably and efficiently since installation. The GridBoss makes grid interaction smooth and dependable, while the 18KPV inverter delivers plenty of power for my needs. The wall-mount batteries are compact, well-built, and hold charge efficiently. Overall, this EG4 solution has exceeded my expectations — highly recommended for anyone looking to build a stable and scalable solar power system.

This is the Ferrari of Sauna. The quality, craftsmanship, and durability of this product is TOP NOTCH. Paired with the Harvia Heater, it is an exceptional sauna. The look is so modern and chic. Easy to clean, looks great everywhere. And the tech setup for the Harvia is so simple, I was up and running in 5 minutes. Could not recommend this more. Also. If you really want you can fit more than 3 it is quite spacious. 10/10

Great tub, easy setup

It’s amazing that this is a portable hot tub. It was easy to setup and looks like a permanent hot tub! It took about 2 days to heat to 104. We live in a place that snows so we added extra insulation to the panels and extra ground cover.

The jets are not super strong so I would have preferred getting the Tribeca which is less expensive and comes without jets. It does have bubbles.

But overall a great product, first of its kind I believe.

Outdoor Sauna CL4G Cube

We pre ordered this sauna. It’s all put together with the help of a contractor. It took 2 guys 2 full days. We are very pleased with the sauna all together. It’s clearly top of the line. The sauna fits 2. Maybe 3 if you want to squeeze. The sauna fits well in our backyard. It adds a sense of tranquility to our favorite space. Off grid was extremely easy to work with. It was clear they put the customer first!

Love the machine!

I absolutely love the machine. I use it everyday. I was disappointed to see some paint scratches on it when it arrived. However, after some contact with their Customer Service department we were able to sort it out. I highly recommend getting a freeze dryer!

Ideal Power station AC180P

I was in the market for a power station that has enough power and capacity to power my fridge and some essential appliances at my house. I come upon this power station from OffGrid living Solutions and I have been using it since. It has enough power for a longer period of time and has multiple ways to charge (AC/Solar Panels). This station is perfect in size and comes at an affordable price. Thank you OffGrid Living team and Bluetti ....

Anker Solix F2000 with Solar Panels

This unit is perfect for power outages! We were looking for a unit that can power our essentials during outages like TV, fridge, microwave, lights, and our wifi. This unit can also act as a UPS so nothin shuts off when the power goes down. I like to connect my solar panels to the station when it looks like the outage will be extended. GET THIS STATION! YOU WILL NOT BE DISAPPOINTED!

Great Solar Generator!

System performs well in powering things and amazing hardware build quality. One issue I have with AC200Max is that I cannot control it remotely via the internet so when it shuts down due to depletion of battery and turns on again after solar hits the panels, I have no way of turning the AC output on remotely. The other thing is that it lacks portable wheels, carrying this thing is a chore. Other than that, this is a pretty good unit and for those who don't need to have the remote control, this could be your solar generator. OLS team was good and respondant on all of my questions. Overall, this solar generator offers excellent power output and capacity to run nearly anytthing you plug into it.

Great product and keeps you cool during trips

Wave 2 is a quiet portable air conditioner, even when you put in on Max mode. I purchase this is for my van for during the hot days during camping. Love that I can carry this to around with ease. I plan to use the heating feature once it gets colder. I'm happy with my purchase and can't wait to see how it functions on the heating side.

A Game-Changing System

I recently invested in the EcoFlow Delta Pro and I am beyond impressed with its performance.

Setting up the Delta Pro was a breeze. The user-friendly interface and informative display made it easy to monitor power consumption and remaining battery life. Plus, the variety of charging options means I can harness energy from solar panels, car chargers, and regular outlets, making it perfect for both everyday use and outdoor adventures. One of the standout features for me is its portability. Despite its robust power capacity, the Delta Pro is surprisingly lightweight and compact, allowing me to take it on camping trips, picnics, and even to power my work tools at remote job sites.

The customer service I received from EcoFlow was exceptional. They promptly answered my questions and provided helpful insights into maximizing the Delta Pro's capabilities. Overall, I would highly recommend this portable power station.
