How to use DOGCOM Lipo battery safely?

- First charge

Before using the DOGCOM Lipo battery for the first time, please fully charge the new battery with the specific Lipo balance charger for it.

- Charger
Charge the DOGCOM Lipo battery with a specific Lipo balance charger only, other types of charger are not recommended.  

- Charging Current
Battery charging current must never exceed the manufacturer's specified maximum which was regulated by specifications. Higher settings may lead to charging insufficiency, inferior performance, heating, and even leakage.

- Charging Voltage
Charge the DOGCOM Lipo battery at no more than 4.20V per cell (4.25V is the maximum cell charge voltage). As for the battery pack in series, please choose balance charging or charge each cell respectively. Series charging is not recommended.

- Charging Temperature
DOGCOM Lipo batteries must be charged at a place within the temperature range from 15℃ to 35℃, or it may lead to the reduction of charging & discharging efficiency and charging insufficiency. Stop charging immediately if the battery surface temperature exceeds 50°C (120°F).

- Reverse charging is prohibited
Please correctly connect the positive (+) and negative (-) electrodes of the battery, and strictly avoid reverse charging. Reverse charging will destroy the battery cells and may reduce the charging& discharging performance and security of the battery, even resulting in heating or leakage.

- Abnormal charging
If there’s any abnormal condition occurs during the charging process, please discontinue the charging process immediately and consult relevant professionals for disposal.

2. Usage

- Checking Voltage
Please check the voltage of the pack before using it. The voltage difference between any two cells should not be too huge, if within 30mV, no need to charge. If between 30mV-100mV, recharging is advised. If the voltage difference between two cells is too huge beyond 100mV, recharging is required before usage. The one with lower voltage may happen to over-discharge while using, causing battery swelling, heating, and finally deteriorating the performance and shortening the cycle life.

- Discharging Current
Always observe the maximum discharge current of the designed continuous discharging current which was regulated in relevant specifications, or it can become very hot and swell and will deteriorate and cycle life be shortened, causing breakage, internal short-circuit, etc.

- Discharging Temperature
Ensure the battery temperature during discharge remains within 65℃, if higher, the battery should be suspended using until it cools down to ambient temperature naturally. Higher temperatures may result in battery swelling and performance deterioration.

- Minimum voltage
Please make sure the cut-off voltage is not lower than 3.0V, and we highly recommend not lower than 3.3V, otherwise, the battery's performance may be severely affected because of over-discharging.

3. Storage & Transportation 

- Transportation
Please avoid severe vibration, shocks, extrusions, and high temperature during batteries' transportation, and please do take care while carrying them. All batteries should be packed with soft materials for protection.

- Long-term storage
If stored for a long time, batteries must be stored at about 3.8V/cell (approximately 50% charged) in the semi-electric status (about 3.8V). Do regularly charge & discharge them for maintenance (about 1-3 times every 3 months).

- Storage Environment
Do store DOGCOM Lipo batteries at a place with low humidity and free from corrosive gas within the temperature range from -20℃ to 40℃.

4. Precautions and warnings

- Crashing, hitting, bending, and short-circuit batteries are prohibited.
- Under any circumstances, disassembly of batteries is prohibited.
- Do not throw DOGCOM Lipo batteries into a fire or soak batteries in any liquid.
- Do not store DOGCOM Lipo in a car or other container that may get hot.
- Always land your model when the power starts to reduce.
- The replacement of bare cells should be conducted by the supplier rather than the user.
- Used or damaged batteries shouldn’t be discarded at random, but should be handed to a specific Hazardous Waste Facility for disposal.
  1. - Store DOGCOM Lipo batteries in a part-charged state and out of children.
