Frequently Asked Questions (FAQs)

What’s the cycle life of the LiFePO4 battery, is it available for bulk project purchase?

The lithium iron phosphate cell supports over 4000 charge cycles with low annual capacity decay, service life up to 8-10 years. Stable stock supply is available for bulk procurement and project orders.

What appliances can the max 500W continuous output run? Is it suitable for RV & field engineering?

It powers laptops, mini-fridges, LED lights, cooling fans and small onboard electronics, perfectly for RV refit, outdoor construction and household blackout backup.

Can the station recharge directly with our 200W flexible solar panel?

Yes. Equipped with dedicated PV input port, it directly connects to 200W flexible solar panel to realize off-grid solar charging without grid power.

How about protection performance of the all-aluminum casing for harsh outdoor environments?

Solid aluminum alloy housing delivers excellent shock & scratch resistance; works stably from -10℃ to +45℃ with dustproof & splashproof property for tough outdoor conditions.

Does simultaneous multi-port output trigger overload risk?

Multiple AC/USB/DC ports support concurrent discharging. Built-in intelligent BMS automatically cuts off power against overload, short-circuit and overcharge for safe operation.

Do you provide OEM & ODM customization service for B2B partners?

Custom service including logo silk print, port configuration and package customization is available for distributors and engineering clients with flexible MOQ.

What is your global warranty policy for bulk overseas shipment?

5-year warranty for whole unit and 2-year warranty for battery core. All items are certified with CE/FCC to meet customs clearance requirements of global markets.

How long can the full-charged 1000Wh unit sustain low-power devices?

For a 50W LED lamp, continuous runtime reaches around 20 hours; runtime varies inversely with the actual load power of connected appliances. Gaotu Innovation - ES900 Portable Energy Storage - Specification - 202512.pdf PDF
