Zendure SuperBase Satellite Battery – Plug-and-Play Expansion for SuperBase V

Adding this satellite to my SuperBase V took literally three minutes — roll it over, connect the cable, and it just appears in the app. Capacity doubled instantly and the system manages charging and discharging seamlessly. No configuration, no fuss. If you own a SuperBase V and ever wish it lasted longer, this is the answer.

Seamless expansion. The unit stacks neatly, looks like it belongs, and the app shows combined stats correctly. My backup time went from one evening to nearly two days of essentials.

It's a big battery so of course it's heavy, but the wheels make repositioning manageable. Integration with the SuperBase V is flawless. One star off only because of the price at full retail — at the sale price it's a no-brainer.

Works perfectly. Doubled my capacity with zero hassle.

Out of the box the satellite wasn't recognized by my SuperBase V and I spent a frustrating hour before a firmware update fixed it. After that, it's been flawless for four months — capacity adds up correctly and switching between units is invisible. I just think Zendure should ship units with current firmware. Hence three stars despite the excellent hardware.

Was so happy with the first satellite that I added a second when they went on sale. Now at four units I'll hit the full 23 kWh setup eventually. Each one integrates identically — plug in, done. For whole-home backup this is far cheaper than a wall-mounted system and doesn't require an electrician.

We run a cabin on solar and the SuperBase V plus two satellites gets us through cloudy stretches that used to force generator use. The build quality is excellent and the handles make it easy for my wife and I to move them around, though they're no featherweights. The app's energy breakdown helps us teach the grandkids about conservation too. Genuinely life-changing for us.

Capacity expansion works exactly as advertised and the charge/discharge handoff is seamless. During high-load charging the satellite's fan is audible in a quiet room, though it's quieter than the main unit. Still very happy overall.

What I love about the Zendure ecosystem is that I didn't have to buy everything upfront. Started with the SuperBase V, added this satellite a year later when my needs grew, and it slotted in perfectly. No proprietary nonsense, no compatibility worries. The battery chemistry holds charge well too — barely any standby loss over a month. Highly recommended.
