Hit 20kWh at 400V nominal, so it’s basically a workhorse for electric vehicles or stationary storage — we’ve seen it handle daily cycling without much fuss, and the 185kg weight means you’ll want a lift for insallation.

400V 50Ah NMC Battery Pack

Continuous discharge is 50A, but you can push 100A for 30 seconds or so — that peak gives you enough headroom for quick acceleration or load spikes, though it’s not designed for sustained heavy draws (check your duty cycle).

NMC Battery Pack Internal Structure

Cycle life is 2000+ cycles, which holds up better than some older chemistries we’ve dealt with, and BMS covers overvoltage, short circuits, and thermal runaway — UN38.3 and CE are in place, so shipping is straightforward.

Battery Pack Testing

Operating range is -20°C to 60°C, but capacty drops roughly 10-15% below freezing — most buyers go with the metal case for added durability, and liquid cooling is worth it if you’re running it hard in hot environments.

Certified Battery Pack

You can scale it from 12V up to 800V by connecting in series or parallel, and OEM service is availble — lead time is usually 4-6 weeks, but confirm stock before ordering.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for this 400V 50Ah NMC battery pack?

MOQ is typically 10 units for standard orders, but we can discuss smaller trial quantities for first-time buyers if needed.

How long is the lead time for a batch of 50 units with OEM customization?

For a batch of 50 units with OEM branding and custom BMS settings, lead time is around 25-30 working days after order confirmation and deposit.

Do you provide UN38.3 and MSDS documentation for shipping this battery?

Yes, all our batteries come with UN38.3 and MSDS certificates as standard, so you can ship them safely by air or sea without extra hassle.

Can this battery pack be configured for a 48V system instead of 400V?

Yes, the pack is scalable—we can reconfigure the series and parallel connections to support voltages from 12V up to 800V, including 48V setups.

What cooling options are available for thermal management, and which do you recommend?

We offer both air and liquid cooling options. For high-rate discharge applications like EVs, liquid cooling is more effective, but air cooling works fine for steady energy storage use.
