SANFOU 12.8V 100Ah Lifepo4 Battery

4S2P with 8 pieces cell, 4S1P with only half pieces, The more cells, the better the quality?

The quality not decided by the number of internal cells.

Fewer internal cells can make the internal stability of the battery higher, lower internal resistance, and reduce the weight of the battery.

How many SANFOU 100Ah Lifepo4 Batteries can I connect in Series and parallel?

It supports up to 4P4S to reach 51.2V400Ah battery system. With 2,048kWh of energy and a maximum load power of 2,048kW.

What is the difference between the old version and the new version of 12.8V 100Ah?

We have optimized the battery.

The old version 12.8V100Ah is composed of 8*3.2V50Ah through 4S2P. The current 12.8V100Ah is composed of 4* 3.2V100Ah through 4S1P.

The weight has also been reduced from the previous 12.5Kg to 11.5Kg.

Can I charge SANFOU 12.8V 100Ah Lifepo4 battery with 100w solar panels?

Sure, you can fully charge 100AH Battery about 12.8hs by use SANFOU 100w solar panel.

SANFOU 25.6V 100Ah Lifepo4 Battery

What size of the trolling motor recommend for 25.6V 100Ah lifepo4 batteries?

We recommend 70 ~ 100 lb

How many SANFOU 25.6V 100Ah Lifepo4 Batteries can I connect in Series and parallel?

We supports up to 2 in series and 4 in parallel (Max 2S4P) to get a 51.2V 400Ah battery system, which with 20.48kWh energy.

Can I use it to start-up my car?

All our batteries 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. Start up can will relase max current, it will huge reduce SANFOU batteries lifespan.

Why does the battery’s max.5-second discharge current exceed the value on the battery parameters and is still discharging? Is the BMS protection function invalid? (SANFOU All battery)

SANFOU BMS protection needs to meet two conditions:

① The instantaneous discharge current of the battery continues to exceed this value

② The internal temperature of the battery reaches the protection value temperature (>55 degrees Celsius)

Since our internal batteries and BMS are made of high-quality materials, even if the instantaneous current generated is very large, the internal temperature of the battery will not be very high, so without the protection if the above two conditions are not met, don't worry about the safety issue.

However, we do not recommend that the instantaneous discharge current of the battery exceeds the value of the battery itself, as this will reduce the service life of the battery.

SANFOU 12.8V 200Ah Lifepo4 Battery

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.

Calculate same as other battery

Why my 200Ah battery does not switch off when overloaded like reach 250A?

SANFOU 12.8V200Ah 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 and series?

Our battery supports up to 4S4P up to 51.2V800Ah battery system.

SANFOU 12.8V 50Ah Lifepo4 Battery

Can I charge SANFOU 50Ah lifepo4 battery with 100w solar panels?

Sure, you can fully charge 50AH Battery about 6.4hs by use SANFOU 100w solar panel.

How many 12.8V 50Ah batteries can be parallel and series?

It supports 4 series and 4 parallel up to 51.2V200Ah battery system.
