Custom Battery Packs

National Battery Supply provides custom battery packs for battery replacements and range extenders. Our custom batteries use high-quality Grade A cells, components, along the best manufacturing techniques. In most of our builds, we actually use pure copper welding with 0.2-0.5mm copper, which is 4 times as conductive as nickel. The low resistance enables your packs to run cooler and push more amps. Our Smart battery management system is installed in replacement packs. Also, we CNC or hand-cut all of our copper and nickel as well.

Custom Battery Pack Solutions & Manufacturing

Our team serves as a full-service custom battery manufacturer with full design and engineering capabilities. We have extensive experience with lithium-ion, lithium polymer, metal hydride, nickel, cadmium, and alkaline battery packs and assemblies. Our most lithium and NiMH custom battery packs require a BMS system (battery management system), which actually manages and maintains each cell, improves battery performance through balancing, overcharge, and discharge.

Why Choose Custom Lithium-Ion Battery Packs?

By using our custom lithium-ion battery packs, you’ll get many added benefits. By customizing your battery packs in terms of voltage and output power, you will get your desired maximum delivered energy.

You can select the right configurations, which lead to longer operating times, and use them on other electric vehicles.

Our team can build your customized battery packs with a dimension shape, connection parts, and maximize the use of available space.

I've been using these LiFePO4 batteries in my RV for over a year now, and they're absolutely incredible! They last 3x longer than my old lead-acid batteries and charge so much faster. The peace of mind knowing I have reliable power for extended camping trips is priceless. Best investment I've made for my RV setup!

Mike T. Mike T.

During the recent power outage that lasted 18 hours, this 3000W pure sine wave inverter kept our refrigerator, lights, and essential electronics running perfectly. No noise, no issues - just reliable backup power when we needed it most. My family felt secure knowing we had this backup system in place.

Jennifer L. Jennifer L.

This portable power station saved our outdoor wedding! When the venue lost power 2 hours before the ceremony, we were able to run the sound system, lighting, and catering equipment without missing a beat. Quiet, reliable, and powerful enough for everything we needed. Our guests had no idea there was ever a problem!

Dave K. Dave K.

These portable solar panels have been a game-changer for our camping adventures! We can charge our phones, tablets, and portable battery pack completely off-grid. They're lightweight, fold up compact, and work great even on partially cloudy days. No more cutting trips short because our devices died - we now have unlimited clean power wherever we go!
