Polinovel Effective Lithium Battery Solution

● General

Yes, we accept sample orders to test the quality and service first. It’s also an excellent opportunity to better get to know each other before establishing deep cooperation. Just tell us the battery model or specification you are interested in.

No limited, but the more quantity you order, the better price will get.

● Product

To get the correct battery for replacement, you need to know your voltage, capacity, power, and size requirements. Don’t hesitate to contact Polinovel technical support if you need assistance. They will be happy to assist you in choosing the correct battery.

LiFePO4 batteries can charge as fast as 1 hour. While a rate that charges in 2-5 hours is more recommended, which is good for the lifespan of a lithium battery. Please get in touch with us for more detailed recommended charge rates.

BMS stands for Battery Management System. It works to protect the cells from getting damaged against over or under-voltage, over-current, high temperature, or external short circuit. In addition, the BMS will shut off the battery to protect the cells from unsafe operating conditions. All Polinovel batteries have a built-in BMS, that are not visible for customers most of the time to manage and safeguard battery against these types of issues.

LiFePO4 batteries can discharge up to 100% without risk of damage. Make sure you are charging your battery immediately after discharge. We recommend discharging the battery to 80-90% depth of discharge (DOD) to avoid the BMS disconnecting the battery.

The discharge rate of the LiFePO4 battery does not affect the delivered capacity. That is not the case with lead-acid batteries, whose capacity decreases significantly as discharge rates increase.

Series connections involve connecting 2 or more batteries to increase the battery bank’s voltage. Parallel connections involve connecting 2 or more batteries to increase the battery bank’s capacity. For example, if you connect 2 x 12V 100Ah batteries in series, the battery system will be 24V 100Ah. If you connect 2 x 12V 100Ah batteries in parallel, the battery system will be 12V 200Ah. Please feel free to contact Polinovel for assistance if you have any connection queries.

Yes, you can mount your lifepo4 battery in any position because there is no acid inside the lifepo4 battery. Instead, a small amount of liquid electrolyte is contained and sealed within the cell. As a result, you have more flexibility to mount the battery where it best suits your application.

● Technical

The reason may be related to the conformity of the battery. In this connection, it is more difficult to make good conformity on different batteries, or the cells in different batteries. The voltage difference between the batteries will get large too, which in turn may lead to high impact current inside the batteries, and damage the BMS.

Active balancing is realized in the form of power transfer, which relies on expensive chips and transformers, and also requires peripheral components that are larger and more costly. It is mainly used in electric vehicle applications. Balancing plays an auxiliary, not a deciding role. The core is to guarantee the battery’s conformity.

● Customization

Yes, customer’s designs such as battery voltage, capacity, charge discharge current, size, shape, terminals, etc are welcomed.

Yes, we accept brand printing on the battery case, label sticker, or silk screen both available.

We also provide functional, appearance customizing services, such as LCD Indication, Bluetooth Monitoring, Handle, Communication, waterproof level, etc.

● Service

Generally, it is 7-20 days for sample orders or 20-35 days for bulk orders. It is according to quantity.

We provide our customers with one-stop-shop lithium battery solutions in custom battery, packing, and accessories if needed.

● Payment

Sample order 100% in advance. Firm order T/T 30% deposit in advance, balance before shipment. If you have another question, please feel free to contact us.

● Shipping

  1. For sample order, by air or by express.
  2. For bulk order, we arrange shipment by sea or by air according to your requirement.

Standard export carton or wooden case according to battery size and weight, the package will be strong enough for long-distance transport.
