بطارية تخزين طاقة 300AH 12.8V LiFePO4

Quality - The capacity of the battery looks the same 3 months after first run so that should mean battery quality is good.

Purpose - I am using them with a 24v All in one invertor from the same brand. Testing the system with 2 batteries with 1500w heater and measuring 220V output shows about 7000wh. First 6000wh was discharged with rate of 40-50A. than I continue on 25A because the invertor shows that battery cannot handle it.
For purposes of my needs batteries work on 50A continues discharging and for rear situetions100A discharging for a couple of minutes.

Capacity - So about 3500wh per battery, not counting invertor losses regarding my tests.

Delivery - in exact 30 days. You need to contact the support first, spatially if it is urgent. Because when products are not at the nearest warehouse it can takes months. It happened before with different purchase.

Support - Support is good but can be reached only viа WatsApp. They don't respond on emails. Chat in a browser also not work for me anymore.
You can reach them starting chat in a browser and than wait in a WatsApp somebody to reach you. They are pretty supportive and helped me with technical details and delivery estimations.

Just waiting for delivery. Delivery more then 90 day... very long
