Frequently Asked Questions
We have compiled a list of answers to frequently asked questions about Battery Bro. If you think a question should be added to this list please contact us and let us know.
What is an 18650 battery?
A 18650 battery is the most promising and popular commodity-type cylindrical lithium-ion cell which finds its use in everything from laptop packs, electric vehicles, to personal vaporizers and space rovers.Recently 21700 and larger formats are showing promise to surpass them because of better energy densities.
Are we Chinese?
The co-founders of Battery Bro are American and Swiss. However, our staff is spread out over the world including in China. We like to think we have the costs of the Asian wholesaler with the vision of a silicon-valley startup.
Why did you make Battery Bro?
The future of humanity rests in the world's ability to store and discharge energy efficiently. It is the perfect time to step in and provide high-quality, authentic power for new technologies like drones, vapes, and electric vehicles. There are far too many counterfeit lithium-ion batteries and information is inaccessible. We wish to facilitate improving energy storage by combating fake batteries and publishing clear, accessible information.
Why should I switch to Battery Bro, I already have a good supplier?
Because you shouldn't settle for less. Once a battery is found to be faked, have specifications exaggerated, or under-performs, your customer will likely try a competitor's product instead. If you are racing, fishing, or competing to be the top in your space, having Grade A batteries makes all the difference. And always safety is absolutely paramount and can only be guaranteed with authentic cells. It sounds scary, but it is true, and there are countless reports of counterfeiting and large well-known brands selling millions of fake batteries every year which can lead to explosions and serious injuries.
We stand behind the batteries we sell.
- We are laser-focused in providing only the best, 100% authentic, Grade A cells
- We are dedicated to providing efficient, effective free consulting
- We are often cheaper because of our close relationship with manufacturers in Asia
- Our policy is to be transparent, honest, and open
How does Battery Bro work?
Our MOQ is 50 batteries but we have the capacity to contract manufacture millions of cells depending on the requirements. DAP or DDP terms apply for air freight. Purchase with a credit card, or bank transfer. For larger orders or custom battery packs we work closely with our clients every step of the way.
What other services do you offer?
We also do on-site factory inspections, quality-control, and build custom lithium-ion battery packs.
Do we ship outside of the US?
Yes! We ship worldwide to most countries. Many countries do have sanctions or shipping restrictions for lithium-ion -- if this is the case get in contact and a support representative will look up the current regulations for you.
How can we provide such low prices?
We are a group of Americans that launched the business in Hong Kong. We have years of experience and the relationships or “guanxi” needed to bring you factory-direct pricing. Our established logistics accounts means you never have to worry about goods arriving or paying more than you have to under Incoterms set.
Do we sell to individuals?
No, we strictly sell B2B for example to businesses, researchers, and manufacturers. We may sell to university students and DIYers with good credentials. Battery cells are not intended to be handled individually by consumers and doing so is a gross misuse of the product.
Where are we located?
The members of Battery Bro are located all around the world so we can provide faster service to all time zones. We also have dedicated workers in Mainland China handling logistics, engineering, inspection, and other tasks and an R&D team in Europe. Most products ship out of Hong Kong or Shenzhen.
What is your MOQ?
Our MOQ is typically 50 battery cells, however for certain models that are not readily in production, we may request an MOQ of 5,000 or higher (especially for small format lithium polymer cells). Custom electrolyte and battery chemistry or shape can require a purchase of 50,000 cells or more.
What kind of batteries do you sell?
We are laser focused on only selling lithium-ion rechargeable batteries. We focus on the commodity cylindrical type - 18650s but also supply other sizes like 21700, 26650, coin cells, lipo, and prismatic cells.
What is so special about lithium ion?
Lithium-ion is a relatively new battery type that is fueling the rechargeable revolution. It has a very high energy density, a long cycle life, and is now very safe for manufacturers to use.
