1. Become An Expert On Your Application.

Depending on power performance needs, size limitations and the other electronics a system runs off of, battery requirements often vary. Before you’re able to design a custom battery, you must be knowledgeable about your product.

Once you partner with a lithium-ion battery consultant, you receive guidance on how to determine your voltage, Amp-Hours (Ah) and other measurements needed for designing a battery solution.


2. Determine Your Required Energy Charge.

There are a few measurements that go into properly sizing for a custom battery. When talking about batteries, “sizing” does not just refer to physical size, but also your battery’s energy charge. You must take into consideration:

--Depth of discharge
--Cycle life
--Recharge rate
--Daily capacity needed
One of the most common mistakes engineers make when designing a battery solution is neglecting to factor in the Amp-Hours (Ah) usage needed between discharge cycles. It’s also common to design a battery that doesn’t have enough capacity to efficiently operate your system, especially if you fail to consult an expert.

You may consider designing multiple smaller batteries instead of one large battery to fit your product. This versatile option allows you to change out your batteries more easily due to their smaller size and lighter weight. However, be mindful that too many small batteries may put you at higher risk for bad connections.


3. Create The Right Shape Battery Solution For Your Product.

Sometimes, oddly shaped lithium-ion batteries are necessary to power your application most effectively. While finding an off-the-shelf battery may be impossible in this case, a custom-designed battery will be a perfect fit.

However, when designing the shape of custom batteries, many engineers make the mistake of mixing up European sizes (DIN) and U.S. standards (BCI). Unfortunately, this results in a battery that doesn’t fit or doesn’t work for your product. A lithium-ion battery expert is able to help you avoid this mistake.

With a custom lithium battery, your application benefits from a battery designed specifically for your system’s needs and optimal performance. Plus, your customers receive all the performance advantages lithium has to offer.
