Two 5.12/5.32kWh batteries have a continuous discharge of 100A. This means that the maximum charge/discharge is limited to the 90A of the inverter. Other Current Limiting Factors Your current should also be suitable for the rated current of your battery cables.
The battery charge/discharge rates are measured in current (A). To work out the maximum charge/discharge power of the battery you will multiply this current (A) by the BMS voltage. The BMS voltage of a battery will vary between make/model/manufacturer so always refer to your batteries datasheet/manual for the correct current and voltage limits.
You set the charge/discharge current for the batteries on the inverter in the battery setup page of the settings menu. The Sunsynk 5.12/5.32kWh batteries have a capacity of about 100Ah and a 50A continuous charge/discharge current so you can set the capacity charge and discharge using these values.
The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
The higher the discharge current, the more power the battery can provide. For example, a battery with a maximum discharge current of 10 amps can provide twice as much power as a battery with a maximum discharge current of 5 amps. This number is important for two reasons.
As the discharge rate ( Load) increases the battery capacity decereases. This is to say if you dischage in low current the battery will give you more capacity or longer discharge . For charging calculate the Ah discharged plus 20% of the Ah discharged if its a gel battery. The result is the total Ah you will feed in to fully recharge.

The discharge rate is usually expressed in terms of amperes (A) or milliamperes (mA). For example, a common AA battery has a discharge rate of about 2.4 A. That means that it can provide 2.4 A of current for one hour, or …
The safe discharge limit for Absorbent Glass Mat (AGM) batteries refers to the minimum charge level that should not be exceeded to maintain battery health and longevity. Typically, this limit is around 50% of the battery''s total capacity.
Technically the minimum amount of voltage for charging will be anything above the current state of charge. But that''s probably not the answer you''re looking for, from Lithium-ion battery on Wikipedia:. Lithium-ion is charged at approximately 4.2 ± 0.05 V/cell except for "military long life" that uses 3.92 V to extend battery life.
Max Continuous Discharge Current (A)=C-rate×Battery Capacity (Ah) Example: For a 5000mAh (5Ah) battery. ... The DOD represents the percentage of the battery''s capacity used during discharge. For instance, a DOD of 80% means 80% of the total capacity is consumed. A discharge to at least 80 % DOD is referred to as a deep discharge.
The Peukert value or exponent is directly related to the battery''s internal resistance. The higher the internal resistance, the higher the losses while charging and discharging, especially at …

The service life of a deep cycle battery is measured in discharge cycles. This is usally promised by the manufacturer of the battery. Each 100ah promised by your battery bank is at a 20 hourly rate at 5 amps. The amp-hours drops the greater the current draw. At 5 hours on a 100 a-h battery for example you might get 82a-h at 16 amps.

Common AGM Battery Limits: – Maximum discharge current – Maximum charging current – Recommendations from manufacturers. Discharge Current: The discharge current for AGM batteries typically should not exceed 0.2C to 0.3C. This means for a 100Ah battery, the maximum continuous discharge should be between 20A to 30A.
A current required for a 1-hour discharge is described as 1C, a 2-hour discharge is C/2 or 0.5C and a 10-hour discharge is C/10 or 0.1C. The table below shows the discharge times for different C-rates.
Max. Discharge Current This is the maximal current a battery can provide without overheating. Over this current the battery overheats which leads to quick damage and a significantly lower capacity compared to nominal capacity. However, peak current might still be possible (1-2s) when switching on appliances.
So, for example, in a battery with a battery capacity of 100 Ah, you can use up to 80% of the battery capacity, or 80 Ah, before you need to consider recharging the battery. What is depth of discharge in batteries?
Does anyone know what the maximum discharge current of various m18 batteries is? Specifically looking at using either an 8.0 or 12.0. In some anecdotal testing that others have done, it seems like certain tools will draw 80-100A peak, that should be enough for this starter, but it would be cool to know if there was some margin.
Battery discharge on a turned-off system should be a fraction of that. If you consider that a disconnected Lithium Polymer charged to about 60% can last months without falling below 40% at room temperature it indicated. Wikipedia has a table showing self discharge of various types of batteries - and bandies a rate of 2-5% per month depending on ...
