The client was referred by our old customer who bought lifepo4 battery from us.

The batteries are for replacing the existing acid battery on a sailboat.

Currently there are 4 units of deep cycle battery of 200Ah that fit into a compartment of Length 680mm x Width 850mm on a boat. 

According to the boat manual, the minimum requirement is 4 units of 140AH battery. 

However, the power requirement on the boat now is far higher than 140AHx 4, with many new electrical equipment installed.  

Boat system is 12V. 

The original and minimum requirement for power is 140AH x 4 = 560AH , but customer thought he need higher capacity now, as they have higher electrical consumption on the boat now, so they would like to make use of the storage space for service battery we have on the boat, which is Length 680mm x Width 850mm x depth maybe around 220mm.

According to the request and condition，we suggested customer to chose Thunder Sky Winston Battery 3.2V 700Ah LiFePO4 prismatic cells.

Our customer from Malaysia purchased 4pcs Winston Battery 700ah batteries and 1piece BMS 300A from us.

The winston batteries and BMS were shipped to door service by sea and the delivery time only took 23 days.
