Why 80Ah?

As lithium cells become larger, their cycle life decreases, 80Ah is a good balance between practicality and lifespan.

Daly

Using top quality (A-level) protective integrated circuit IC, from Seiko of Japan. The IC itself has power a balancing function. The circuit is simple and reliable
Strong load ability, high constant discharge current, using high voltage tolerant and ultra low resistance power MOSFETs. Daly's extra large heat sinks and sealed thermal coating greatly assist cooling
Voltage detection for each cell so each cell will be protected from over charge or over discharge. The over current and short circuit protection function is a built-in feature to preserve the life of both the BMS and cells.
Temperature protection during charging and discharging
Extremely low power consumption. The consumption of the whole device is between 50 - 600uA depending on the model without Bluetooth. While the Bluetooth module is on, 15mA.
Program via UART to PC cord or let Solar 4 RVs know your battery capacity and we can program the unit for you

With the repeated charging and discharging, the battery's capacity will gradually decline. The number of charge-discharge cycles a battery can go through before it reaches 80% of its rated capacity called cycle life.

5-YEARS after-sales guarantee. If there is a serious non-compliance with the technical standards of A-grade cells not meeting the following:

the cell capacity must meet or exceed 80ah
capacity tolerance within 1.5 Ah
voltage tolerance within 5 mV
resisitance tolerance less than 0.2 milliohm

Daly

Daly guarantee a 3-year product warranty, if the damage is caused by improper operation, we will conduct the repair with charge. The warranty does not cover shipping costs, the cost of shipping both to and from the user must be paid for by the user.

Assembly

The assembly of the cells and BMS is a free service Solar 4 RVs supplies and the warranty provided covers the individual components, not as a single unit. Therefore, if a BMS failure were to occur, a replacement BMS would be supplied under warranty, likewise if a single cell were to fail, a replacement cell would be supplied to the user. Solar 4 RVs will replace any faulty cell or BMS into an assembly as a free service if the end user returns the assembly back to base but Solar 4 RVs will not cover any labour costs by a third party.

Failure of LiFePO4 cells is incredibly rare and when an appropriately sized and high quality BMS is used, the failure rate of the BMS is also incredibly rare.
