Some FAQ About Energy Storage

Why use lithium iron phosphate batteries?

Lithium iron phosphate batteries(LFP) are much safer, longer life-span, and saving more space than many other lithium ion batteries, deep cycle is supported.

Can I custom my energy storage battery?

Yes, lithium ion batteries are customized and modularized. The exterior case, the capacity other than 200Ah, the BMS with active balancing and more are your option.

Are other modules also provided?

Yes. Though we are a battery manufacturer, other modules like solar panel, inverter, charger, and many others can be also provided as integrated system if require.
