The above video explains the best way to store a lithium battery if you are not going to be using it for an extended period of time. This may be during the winter or in the summer for people only using their batteries for ice fishing. Below is a brief overview of this video.
1) Store your battery approximately 50% capacity. If you have Bluetooth this is easy to figure out. Without Bluetooth here is a good voltage for storage.
- 12.8V LiFePO4 - 13.3V
- 24V LiFePO4 - 26.6V
- 36V LiFePO4 - 39.9V
- 14.8V NMC - 15V
2) Never leave electronics or trolling motors attached to the batteries in storage. All devices connected to the battery will have a parasitic draw. Devices left attached to the battery will draw power when not in use. This can deplete a battery over time or even cause battery failure if stored fully depleted.
3) Charge every 3-6 months. We encourage a battery sitting for 3 months to be placed on a charger for a short period of time (10-15 minutes). Try to never go longer than 6 months without a charge or use.
4) Storage Temperatures: As with any battery, you want to make sure you store you batteries in temperatures between 40-80 Degrees. Lithium batteries are able to handle a wider temperature range than other batteries, but for proper long term storage and life expectancy, 40-80 degrees in a dry environment is the most ideal.
