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.

Let customers speak for us
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.
lichter, meer cycli en capaciteit duurzaam.waard.
200Ah plus with 200amp BMS, it‘s awesome, I had purchased 2pack 100ah lead acid batteries, and now replace them with this lifepo4 battery, and it only weighs about 20kg, and works well with the solar panels we have installed on the campervan, quite a good battery!
I bought these batteries for solar storage on my off grid life, they were well packaged and quick delivered. Thanks for the great price. They are great product.They appear to be high quality and are exactly what I wanted.
I am very happy with the battery. A backup power source is being prepared. I tried the inverter. Perfect. Assembly remains.
I will definitely buy more. Product and customer service are also very good.
Jumped into rv life using solar generators. I bought this battery to build up my budget solar system and I couldn’t be happier. I plan on buying another so I can get 400ah capacity. Thanks sanfou! And I suspect they will be around as more people take the chance on this "no name" battery and are pleasantly surprised by it.
I bought these batteries for winter energy preparation, recommend buy on official site. I will come back review again after using for a while.
Ezeket az akkumulátorokat az otthoni napelemes rendszerembe telepítettem, és jelenleg mindent, amire szükségem van, és két napig tarthat egy felhős napon, majd a napelemek és az MPPT segítségével feltölthetem az akkumulátort. Csodálatos termék.
expensive,but worth it. I use it for one month.
High quality battery. Purchased after a detailed youtube review.
gran rendimiento, la extensión de la sanfou batería gran elegir.
