Frequently Asked Questions

Get answers to the most common questions about our LiFePO4 batteries and solar storage systems.

What is a LiFePO4 battery?

LiFePO4 (Lithium Iron Phosphate) is a type of lithium-ion battery known for its high thermal stability, long cycle life, and enhanced safety compared to other lithium chemistries.

How long do your batteries last?

Our LiFePO4 batteries are rated for up to 6000 charge cycles at 80% depth of discharge, which translates to over 10 years of daily use in most applications.

Are your batteries safe?

Yes. LiFePO4 chemistry is inherently safer than other lithium types. Combined with our advanced BMS, our batteries offer protection against overcharge, short circuit, overheating, and over-discharge.

Can I connect multiple batteries in series or parallel?

Yes, many of our battery models are designed to be connected in series or parallel to achieve higher voltage or capacity. Please refer to product specifications or contact us for guidance.

Do you offer OEM/ODM services?

Yes, we provide custom battery solutions including design, branding, and packaging tailored to your requirements.
