2.5
Discharge current
The battery discharge current cannot exceed the maximum discharge current specified in the specification. Excessive current
discharge will cause the battery to heat up and reduce its capacity.
2.6
Over-discharge
The battery may be permanently damaged when the battery voltage is less than 6V, and the product quality assurance of
Soshine will be invalid. According to 11.1.3.2 this specification, the internal energy consumption of the system should be reduced
to minimum when the discharge cut-off voltage is below 10.8V, and the storage time is prolonged before recharging. The
customer needs to train the user to recharge the battery in the shortest time to prevent the battery from over-discharge state.
2.7
Battery storage
If the battery is expected to be stored for more than 30 days, the SOC should be adjusted to about 30%. If the battery is expected
to be stored for more than 180days, the SOC should be adjusted to about 80% and the battery to be charged and discharged at
least once in the whole SOC range ( 10.8~14.2V) for every 90 days .
2.8
Charge at low temperatures
The battery should avoid charging (including standard charging, quick charging, emergency charging) in the low-temperature
conditions which is prohibited in this specification, otherwise, unexpected capacity reduction may occur. The battery
management system should be controlled according to the minimum charge and regenerative charging temperature. It is
forbidden to charge when temperature is lower than the temperature conditions specified in this specification. Otherwise, Soshine
shall not be liable for quality assurance
2.9
Battery heat diffusion
In the design of the electric box, the heat diffusion of the battery should be fully considered. Soshine shall not be responsible for
the quality assurance due to the overheating of the battery or battery caused by the design of the electric box.
2.10
Waterproof and dustproof
The waterproof and dustproof problem should be fully considered in the electrical box design, and the electric box must meet the
waterproof and dust-proof grade stipulated by the relevant national standards. Soshine is not responsible for quality assurance
due to the damage caused by the waterproof and dustproof problem (such as corrosion, rust, etc.).

Charger Requirements
3.1
Special charger for LiFePO4 battery
It is recommended to use a special charger for LiFePO4, constant current and constant voltage charging (fully charged cut-off
voltage 14.2V), with short circuit protection, overcharge protection, reverse connection protection, and anti-backfill function.
Charging current 12A (max).
3.2
Solar panel intelligent charge and discharge controller
Select LiFePO4 charger mode.
Constant current and constant voltage charging (fully charged cut-off voltage 14.2V), with short circuit protection, overcharge
protection, reverse connection protection, and anti-backfill function.
Charging current 12A (max)
3.3
Lead-acid battery charger
It is recommended to use three-stage charger with overcharge protection, and short-circuit protection.
Voltage range: charge cut-off voltage 13.5~4.6V, float voltage 13.7~3.8V, over discharge voltage 10.8~11V.
Charging current 12A (max)
Lead-acid chargers that meet the above requirements can be used, but the battery may be overcharged, and the long-term use
will shorten the life of some batteries or not fully charged, and the full capacity will be reduced by about 5% compared to the
normal capacity.
