Eyes on Ukraine has added a new tool to our arsenal: universal 5kWh expansion batteries for EcoFlow power stations.

These expansion batteries increase the capacity of EcoFlow Delta 2 and Delta 3 power stations from 1–2 kWh to 6–7 kWh, providing reliable power for much longer during blackouts and frontline operations.

Here’s how it works:

• We ask our partners whether they use an EcoFlow Delta 2 or Delta 3 and if they need additional capacity.
• They send us a photo of their power station so we can verify the model.
• We ship a compatible expansion battery and connection cable.
• Before connecting it for the first time, we ask them to watch our instruction video. It explains how to match the voltage of the EcoFlow with the external battery before the initial connection—a crucial step for safe operation.

We focus on the EcoFlow Delta 2 and Delta 3 for now, because they use the same battery chemistry and voltage as the external batteries, allowing us to provide simple, reliable plug-and-play connection cables.

Cost per expansion kit (battery + cable): €550–€700

We have already prepared seven expansion battery kits for shipment. As soon as our financial situation allows, we will begin processing the remaining requests. The demand is there, we just need the funding to keep building and delivering them.

Support Eyes on Ukraine and help us deliver more high-capacity power solutions to those who need them most. 🇺🇦
