A Nigerian customer contacted Toppingdom with real photos and video of existing rack-style lithium-ion energy storage batteries and asked for sourcing support. The units shown are branded ES Energy Storage System by IPT Powertech. Visible interfaces include P+/P− terminals, RS485-A, RS485-B, RS232, address settings, dry contact and SOC indicators.
Important: the small specification label in the supplied photos is not clear enough to responsibly confirm the exact voltage, Ah or kWh rating. We do not guess these values. Before matching a replacement, the battery label and inverter/system specification must be confirmed.
What we check from a customer photo
- Battery chemistry and nominal voltage
- Capacity in Ah and usable energy in kWh
- BMS and RS485/RS232 communication
- Inverter compatibility and communication protocol
- Terminal layout, rack dimensions and installation method
- Required quantity and whether all units must be identical
- UN38.3, MSDS and other shipping documents required by the selected route
Why matching matters
Two batteries can look almost identical while using different voltage windows, BMS protocols or communication settings. A cheaper battery is not a saving if it cannot communicate correctly with the customer's inverter or existing energy-storage system.
How Toppingdom handles this type of inquiry
We convert the customer's photos into a supplier checklist, request comparable models from China, compare the confirmed specification and packing data, then review the China-side cost and available logistics route. Lithium batteries are sensitive cargo, so the shipping method must be confirmed before payment.
Information to send us
Send clear photos of the front panel and specification label, inverter brand/model, required quantity, whether the battery is a replacement or a new system, and your delivery city in Nigeria. If possible, include a short video showing the current installation.
