SOC Data Sheet
Why my 200AH battery does not switch off when overloaded like reach 250A?
SANFOU 12.8V200A is equipped with a 100A BMS and supports a maximum discharge of 3C, which corresponds to a current of 300A.
However, for the safety of the battery and the protection of the electrical devices used, our instructions indicate that the maximum discharge is 200 A in 5 seconds. The actual battery triggers the BMS protection when discharged with a maximum current of 300A.
Don't worry about quality and safety. Our batteries without safety issues and BMS provide powerful protection features.
How many 12.8V 200AH batteries can be parallel?
Our battery supports up to 4S4P up to 51.2V800Ah battery system.
Can 12.8V 200Ah be used to start up my car?
Our battery is suitable to charge most devices on the car, which can be the best replacement of lead-acid battery on travel, but we don't suggest using it as a start-up vehicle engine.
How long will the 200AH battery completely discharge?
Discharge (hours) = Battery Capacity (Ah) / Current (A)
Take an example, 200Ah battery discharging at 20A ,it could run 10 hours.

Este a doua baterie pe care o cumpar.A sosit in cateva zile.Relatia cu vanzatorul excelenta.Multumesc Sanfou.
Ár/érték arányban a legjobb
J'ai installé deux upgrade 100ah dans un double coffre à batterie sur ma remorque. Je les ai chargées et j'ai campé pendant 5 jours avec beaucoup d'énergie encore disponible. Les ventilateurs, le réfrigérateur et l'éclairage sont alimentés au maximum. Satisfait de cet achat. Le plus important, c'est qu'il y a moins d'espace.
mppt screen explanation helpful, running paired with sanfou battery, accurate data and the charging progress is normal. I will check it again after using for some while.
I bought two of them a few weeks ago. I'm using them in a 24V offgrid system and they do the job very well! These batteries can really do the rated capacity! Huge upgrade from acid batteries. I recommend it.
Cela fonctionne comme prévu. Je suis très content qu'ils fonctionnent sur mes unités de climatisation. paresseux pour prendre une photo, en utilisant une image enregistrée
great advice on installation, I was absolutely convinced! I discovered this battery on youtube, since now I have been using the batteries for three months and there is absolutely nothing to complain about! a discount campaign before the purchase, I consult sanfou about the discount, they usually responds to emails within a day. Everything works as it should, you get support, that's how it should be!
Fast delivery and runs great. With carry handle, it's 10kg but so much better than the lead acid batteries I was using before, the battery casing is very sturdy, the instructions are clearly written, refer to some of the cable sizing recommendations for parallel and series. The delivery packaging does a good job of protecting the battery.
