How many volts should a deep cycle battery discharge?
However, The deep cycle batteries FAQ states that it is not advisable to allow your batteries to discharge below 50% of the batteries capacity. That would be below 48.24 volts. My system starts with a full charge (about 51 volts read from the XW SCP) and by the time morning comes the voltage all read about 46 volts.
How fast does a lithium battery discharge?
The hotter a given battery is, the quicker it will self-discharge. Most lithium-ion batteries have a self-discharge rate of between 0.5-3% per month. This means that lithium battery will lose between 0.5 and 3% of its charge per month. At lower temperatures, this discharging rate will increase drasticaly. How fast do lithium batteries discharge?
Do lithium-ion batteries self-discharge?
However, it is something that you need to keep in mind when storing the battery or during peak summer heat. If you’re new to the world of rechargeable batteries, then you might be surprised to hear that lithium-ion batteries self-discharge after being fully charged.
What voltage should a 48 volt battery be charged at?
A 48v battery is fully charged at 54.6v. The low voltage cutoff is around 39v. It is best not to discharge more than 80% of the capacity for good cycle life. 80% DOD is around 43v depending on cell chemistry. Li-ion has a flat discharge curve. The voltage will drop from 54.6v down to 50v fairly quickly then level off.
What is a 48 volt battery?
48 V is the nominal voltage. The actual battery voltage will vary depending on state of charge and what its load is at that moment. As you noticed a 48 V battery at full charge with no load is more like 53 V.
How fast do lithium ion batteries self-discharge?
Lithium-ion batteries self-discharge at a rate of around 0.5-3% per month,depending on battery chemistry,enviroment,BMS etc. Strikingly, they discharge very fast while they are still fully charged.
