This battery is great, the capacity is good along with the charging current but the discharge current is amazing to the point where it is more than enough for what I’m needing. Love it.

Nice communication via Whatsapp. Shipment to Greece. All good. Thank you.

These batterys have great capacity and excellent discharge curve will buy more for my next set-up Regards Dave

All four cells has identic voltage about 3.27 volts. Cell package was perfect with foam parts. The next order will be placed at Hakadi.

I am very satisfied with these HAKADI batteries! The only small problem is that the wrap is fragile, so I had to change it all the time. Otherwise, these are excellent batteries that I highly recommend!

Hi colleagues,
I have gratefully received a second sodium battery (210 Ah).

Both batteries work with a BMS (4s 200 A).

The two BMS are connected in parallel.

The batteries are used as storage for the emergency power supply of an oil heating system.

The batteries are charged via a Victron 100/30 charge controller of a small PV-system.

The charge controller was set to a maximum voltage of 15.5 V.

The batteries are monitored via a TeView app.

A 24-hour test was successful.

The batteries completely met my expectations.

Thank you very much!

W.H.
