Other important things to note:

  • The maximum charge current for our 12V 50Ah battery is 14.6V, with a 10.5 discharge cut-off voltage.
  • The max charge current is 50 amps and the max discharge is 50 amp /170 amps (3s).
  • Solar chargers can be used!
  • Most standard lead-acid chargers without a “Desulfate” mode can be used. (As long as the current levels do not exceed the lithium battery charge requirements).
  • Your 12V 50Ah battery can be completely charged with a standard lead-acid charger that achieves 14.4-14.6 volts.
  • Battery chargers with a voltage of fewer than 13.6 volts will only charge the battery to 50% capacity or less.

Frequently Asked Questions

Can this battery be combined with a 12V lead acid battery bank?

We highly recommend NOT stringing lithium batteries to any lead acid batteries. Otherwise, the battery will be damaged. When wiring batteries, it’s recommended to connect batteries with the same type (lithium), same capacity (Ah), same voltage (V) from the same brand.

How should I handle the battery after it arrives?

When you receive your battery, please be aware that it may have a low State of Charge (SOC) due to the transportation and storage process. To ensure its optimal performance, we recommend charging the battery right away to avoid over-discharge. If you plan to store the battery for an extended period without usage, we suggest charging it to a SOC of 30% to 50% and performing maintenance every three months. These steps will help maintain its functionality and performance over time.

How long will a 50Ah lithium battery last?

roughly 10 years

On average, our 12V 50Ah battery lasts a whopping 3,000 to 5,000 cycles. This equates to roughly 10 years of battery use. Cycles are the number of times your battery is fully charged and then discharged. Most lead acid batteries have a usable capacity of 50-60%, meaning you have to charge them much more frequently.

What is the difference between a 50Ah and a 100Ah battery?

The only difference between using a 50Ah and a 100Ah battery is the amount of time that it will take to charge and how long you can run things. The power will last twice as long before you need to charge but then it will take twice as long to charge.

How long does it take to charge a 50Ah lithium battery?

How long does it take to charge a 50ah lithium battery? In a real sense, charging takes 2-5 hours at 0.2-0.5C per minute.
