A battery lifespan is rated by the number of cycles before the original capacity has reduced
by a certain amount; a cycle is defined as discharging from fully charged, to a percentage
Depth of Discharge (DOD), and then charging back to full again. So, DOD describes what
percentage of the battery capacity is being used each time.
Note: DOD is different to State of Charge (SOC, also known as Charge Level); in fact, they
add together to 100%. So, 80% DOD equates to 20% SOC.
The less DOD you use each cycle, the longer the battery will last.
This fact should be considered when choosing the battery Amp hour capacity. You will have
a higher return on battery investment if there is enough capacity at hand such that you are not
heavily discharging the battery on every cycle. Extra capacity ensures lower DOD, extended
life and a higher financial return on your investment.
LBS SP batteries have a cycle life of 5,000 at 50% and 2,000 at 80% DOD.
4.0 Battery Management System
Your battery comes with a Battery Management System (BMS) mounted internally.
The BMS is an electronic solid-state circuit board which manages the cells and protects the
battery across a range of scenarios which primarily includes over charge and over discharge
protection. Unlike lead acid batteries, over charging or over discharging a lithium battery may
lead to a hazardous scenario. Therefore, the BMS is the heart and soul of a lithium battery.
The Standard Power (SP) family BMS is a highly reliable solid-state device which is primarily
designed to keep the cells safe and the overall pack from being damaged by excessive voltage
or excessive discharge event.
The LBS High Power (HP) family has a BMS with sophisticated diagnostics and if that is a
requirement of your design then contact LBS about their HP battery products.
