What are some common questions to ask when buying lithium batteries?
Every product has its value and demand, and it must first be accepted by the market and appreciated by consumers. For procurement personnel engaged in lithium battery procurement business, only by having a more detailed understanding of various aspects of lithium batteries can they select products with high cost-effectiveness.

Lithium Storage are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

1. Are Lithium Batteries in Stock?
Lithium batteries are generally not kept in stock, and belong to the customized products. Different customers have different requirements, and even the voltage and capacity are the same. Other parameters may also be different. Once the order is confirmed, our lithium battery manufacturer can quickly complete the samples.

2. What parameters must be provided for custom lithium batteries?
For custom lithium battery, we need to know the working voltage range, working current, peak current, battery size (storage space), battery capacity, charging current, and so on.

3. What is the delivery time for bulk orders?
The delivery time for lithium batteries is usually about 28 days, depending on the actual situation.

The company is the world’s best lithium iron phosphate battery manufacturer supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

4. What certification certificates do the batteries have?
Due to the fact that lithium batteries are customized products, certificates cannot be used universally and require additional application; you can list the required lithium battery certifications, and specialized personnel will assist in applying together.

5. Is a lithium battery charger provided?
When you purchase lithium batteries, a special charger for lithium batteries is provided. Select a suitable charger from the lithium battery manufacturer to charge the battery; if it is not the charger provided by the original manufacturer, there will be a mismatch and long-term damage to the lithium battery.

I used ABBA logistics to do the customs work, mostly because they were the ones who received the incoming paperwork. You can shop around for this service, but it could only save about $100 max from the service charges. I heard that you can process the paperwork yourself, but it was not worth the trouble for me.

I collected the batteries from a warehouse in Botany. This saved a local delivery charge. They forked the small pallet onto my trailer, but I could just as easily have put the 9 boxes into my car. 200kg battery weight.

A few cells were covered in two layers of the thin blue wrap. They appear to have scratches on the first cover. I consider this to be a very minor defect.

This was my total cost:

They included double bus-bars for me at no extra cost. They are tinned copper 2mm thick, 20mm wide.

Shipping charge from the seller was DAT (Delivered at Terminal) to Sydney/Botany. I paid all other charges locally.

Here is a listing from the same seller, but for the more popular 280Ah size:

Linda Shaw (+86 131 ) at Shenzhen EEL Electronics Co., LTD was very helpful and responsive. All shipping paperwork was provided promptly.

I charged two batteries with a bench power supply and discharged with a battery discharge tester (

I charged to 3.6v (99% SOC) and discharged to 3.0v. After a moment without load, cell voltage &#;recovered&#; to 3.23v (20% SOC). That 79% SOC change should have been 181Ah (.79*230Ah), but I measured 199Ah, indicating that I have slightly more capacity than promised. The cells had test stickers indicating around 236Ah (more than the 230Ah spec). I am off by ~4% on SOC calculation or ~9% on battery capacity, which I cannot explain, but it is in my favour, so I am not worrying about it.

All sampled cells had similar starting voltage of 3.26 or about 35% SOC. I am going to charge the tested cells to the same voltage and try my luck with the Batrium BMS top-balancing them in the vehicle. I will then manually charge/discharge any cells that are causing problems&#;

My recent battery experience on Alibaba: I ordered 45 x 230AH batteries from Shenzhen EEL Electronics Co., LTD. Online reviews were good. I also had a local friend in China check them out, no concerns raised. They had the best price for 230Ah batteries (the best size for my EV conversion) and promised Grade-A cells. From my payment until batteries cleared customs in Sydney was 6 weeks. Batteries were boxed (5/box) with thick foam and arrived in great condition.I used ABBA logistics to do the customs work, mostly because they were the ones who received the incoming paperwork.
