1. Q: Can these battery packs be compatible with my inverter?  do you have a company list of the inverter which is compatible? 
    A: Yes sir, our battery pack can compatible with most brands of inverters on the market, contact us and let me tell you more.

2. Q: Wiring in parallel or series?
    A: When using lithium-ion batteries in a system, one important consideration is whether to connect them in parallel or in series. The choice can have a significant impact on the overall performance of the system, including the amount of available energy (amp-hours).

Connecting batteries in parallel increase the total capacity of the system while maintaining the same voltage. This means that the system will be able to store more energy and deliver it over a longer period of time. For example, if you have two 12V lithium-ion batteries with a capacity of 100Ah each, connecting them in parallel will give you a total capacity of 200Ah while still maintaining 12V.

On the other hand, connecting batteries in series increases the total voltage of the system, while maintaining the same capacity. This means that the system will be able to deliver more power, but for a shorter period of time. For example, if you have two 12V lithium-ion batteries with a capacity of 100Ah each, connecting them in series will give you a total voltage of 24V, but the same capacity of 100Ah.

So, which is the best choice for your system? It depends on your specific needs.

Additionally, batteries wired in series and parallel should be identical batteries with the same voltage, capacity, and BMS rating. Connecting different batteries may lead to problems that may damage them or even more severe outcomes.

3. Q: What benefits of LiFePO4 Batteries Over Standard Lead Acid Batteries?
    A: Lightweight: 
Lithium batteries are significantly lighter than lead-acid batteries, making them much easier to handle and install. Lithium iron phosphate (LiFePO4 or LFP) chemistries deliver about 50% more useable electrical capacity with up to 70% less weight than lead-acid batteries. LiFePO4 units are also lighter than some lithium ion batteries, around half the weight of lithium manganese oxide (LMO) batteries.

Longer lifespan: 
Lithium batteries have a longer lifespan than lead-acid batteries, meaning they need to be replaced less frequently. This not only saves money in the long run, but it also means less time spent on maintenance and battery replacement.

Higher energy density: 
Lithium batteries have a higher energy density, which means they can store more energy in a smaller space. This makes them ideal for use in boats, where space is often limited.

Faster charging: 
Lithium batteries can be charged much faster than lead-acid batteries, allowing for more time in the water.
Battery charging time for LiFePO4 batteries is quicker than for lead acid or other lithium batteries, Typically LiFePO4 units have four times the energy density and charge five times faster than lead acid batteries.
The cycle life for a LiFePO4 battery is up to five times the cycle life of some lithium ion batteries, often reaching up to 5000 cycles without any significant drop in performance.
LiFePO4 battery packs can also run down to 100% DOD (depth of discharge) without any damage or drop in performance.

Better performance in cold temperatures: 
Lithium batteries perform much better in cold temperatures than lead-acid batteries, making them a good choice for boat owners in colder climates.

No maintenance: 
Lithium batteries require no maintenance, as there is no need to add water to them like lead-acid batteries.

4. Q: Bluetooth Functionality
    A: Our LiFePO4 battery is undoubtedly a huge innovation that brings great convenience to the user experience. Also features Bluetooth for displaying battery information on your phone. Just download our APP on the phone according to the instructions.

5. Q: Are the batteries waterproof?
    A: All of our LiFePO4 battery has an IP65 protection class, are Made with quality ABS plastic, has a wide range of operating temp: Charge: 0°C to 50°C(32°F to 122°F); Discharge: -20°C to 60°C(-4°F to 140°F), IP65 level waterproof set you free from worrying to install indoors or outdoors. But when charging or discharging the battery, please be careful not to let the post bolts or terminals come into contact with water, as this may damage the battery.

6. Q: How do I store my battery when not used?
    A: Never store your battery fully discharged. It is best to put a 50% charge on your battery and avoid leaving for a long period of time without charging and in a cool dry place. To ensure the best performance from your batteries for many years, put a charge on your battery at least every 2-3 months. Store your battery in temps of 40-80 degrees and never leave it on the charger or charge it in below-freezing temperatures. 

7. Q: How long can I expect to get the sample? 
    A: The samples will be ready for delivery in 3~7 days after we receive the payment.

8. Q: What products do you offer?
    A: Our main product is Lithium Ion Batteries. Now we can offer Home Energy Storage, LiFePO4 Lithium Battery 12V 24V 48V etc.

9. Q: The battery is heavy, will it damage easily on the shipment?
    A: This is a matter of great concern to us too. After long-term improvement and verification, our packaging now is safe and reliable, please rest assured about that. 

10. Q: Are your battery's real capacity?
      A: All of our battery cells with Grade A, are 100% new, and have real capacity. 

11. Q: How can I contact you?
    A: Email us directly at and we will get back to you ASAP.
