A battery charger of 50 amps, for instance, calls for a cable of 50:3 or 16.6 mm². The standard cable closest to this is 16 mm². This applies when the distance is three metres at most.
Send message »· A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh. Since voltage is pretty much fixed for a battery type due to its internal chemistry (alkaline, lithium, lead acid, etc), often only the Amps*hour measurement is printed on the side, expressed in Ah or.
Send message »The current in the circuit is the result of total voltage divided by total resistance in the circuit. Therefore the total resistance equals the 4ohms plus 0.5 ohms =4.5ohms The current is 3V/4.5ohms =0.667A The terminal resistance is the voltage a.
Send message »Likewise, for the same battery a charge current of 250 mA corresponds to a C-rate of C/2, meaning that this current will increase the state of charge of this battery by 50% in one hour. [4] Since the unit of the C-rate is typically implied, some care is required when using it to avoid confusing it with the battery's capacity to store a charge, which in the SI has unit coulomb with unit symbol C.
Send message »Battery manufacturers might be able to provide an estimate for the actual battery capacity if the application's current profile (e.g., Figure 6.1) is provided. The ratio of the battery's actual capacity to its nominal capacity is called the battery efficiency factor.

Send message »An RV battery at 50% battery will put out between 12.06-12.10 volts, on average. If your voltmeter has a number below this, charge your battery immediately. If you're going to be boondocking a lot, however, it's definitely worth investing in a decent battery monitor or gauge if your RV didn't come with one.

Send message »If you always taking it to 50% or even going beyond it from time to time then you will most likely be on the low end of the average, so 3 years out of a battery given your load is to be expected. If you want to increase your battery life I would suggest a large AH rated pack, as the less you pull from the battery the longer they tend to last.
