FAQs
Q: Can I use Timeusb LiFePO4 Lithium batteries as starting batteries?
A:
Timeusb LiFePO4 batteries are intended for energy storage and are not suitable for use as starting batteries. They lack the Cold Cranking Amps (CCA) needed for starting applications.
For more details, please refer to the article "Deep Cycle VS Starting Battery."
Q: Can I use the Timeusb 12V Lithium Ion Battery 140Ah for my trolling motor?
A:
Timeusb lithium ion battery 12V 140Ah is compatible with trolling motor thrust between 30 and 70 lbs. If you have additional questions, we can provide you with recommendations based on your needs.
Q: What is the maximum number of Timeusb 12V 140Ah deep cycle batteries that can be connected?
A:
Timeusb 12V battery supports versatile connections including series, parallel and serial-parallel connections. You can connect up to 4 batteries in series (4S), 4 in parallel (4P) or 16 in series-parallel connection (4P4S).
Q: Can I charge Timeusb 12V Lithium Ion Battery 140Ah in cold weather (under freezing temperatures)?
A:
LiFePO4 batteries can be safely charged between 32°F to 113°F (0°C to 45°C). Timeusb 12V Lithium Ion Batteries 140Ah feature low-temperature charging protection, which automatically stops charging when the cell temperature drops below 32°F. This prevents damage to the battery cells when charging in freezing conditions.
Q: How Long Will a 12V 140Ah Battery Last?
A:
The duration of a 12V 140Ah battery depends on the current drawn and the specific application. You can estimate this using the formula:
Battery life (in hours) = Battery capacity (in amp-hours) / Load current (in amperes)
For example, if we assume a load current of 10 amperes:
Battery life = 140Ah / 10A = 14 hours
For example, with a 10-ampere load, you can expect approximately 14 hours of continuous operation. However, the actual duration may vary based on factors such as system efficiency, fluctuations in load current, and the overall condition of the battery.
