However, when using the windlass with the engine running, a surprisingly high current can be drawn through the charging cables. If these are enclosed in ducting, they do need to be substantial. Also, with a battery mounted in the anchor locker, you need to put a fuse or a

Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real available capacity will be smaller (it may be much smaller). Discharging the battery with a lower current will extend the real available capacity a little bit.

For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.

Above the initial current spec the battery could be damaged, or outgas dangerous amounts of flammable hydrogen gas, or it could even explode. With a high enough charge voltage you can nearly always get the battery to take more current than the recommended initial current, so it''s important to have a current limiting function.

C-rate is a measure that governs at what current a battery is charged and discharged. At 1C, a battery rated 1,000mAh charges at a current of 1,000mAh. In an ideal world the battery would be fully charged in 60 minutes. At 1C, the same battery discharges at 1,000mA. Li-Ion or Li-PO (both have same charge/discharge characteristics) -typically charged between
Learn MoreInternal Resistance – The resistance within the battery, generally different for charging and discharging, also dependent on the battery state of charge. As internal resistance increases, the battery efficiency decreases and thermal stability is reduced as more of the charging energy is converted into heat.
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.
It is this voltage that generally defines the “empty” state of the battery. Capacity or Nominal Capacity (Ah for a specific C-rate) – The coulometric capacity, the total Amp-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.
Your max realistic discharge rate for your battery bank is well over the the batteries realistic rate of 92a. Your inverter can actually handle peak ac loads near 4000w. This is approaching 350a @ 12v battery. Choose a couple of 12v lithium batteries. They handle high charge/discharge currents better than LA. Ask or advice.
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
This section describes some of the variables used to describe the present condition of a battery. State of Charge (SOC)(%) – An expression of the present battery capacity as a percentage of maximum capacity. SOC is generally calculated using current integration to determine the change in battery capacity over time.
