Longevity & Depth of Discharge
One of the advantages of lithium batteries over lead-acid batteries is longevity. If you want to realise
the long life potential out of your lithium battery, then consideration must be given to depth of
discharge.
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.
Baintech batteries have a cycle life of 5,000 at 50% and 2,000 at 80% DOD.

Battery Management System
Your battery comes with an integrated Battery Management System (BMS).
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 TradiePack battery 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
events.
