LITHIUM BATTERY F.A.Q. 

Q: What is your warranty and claims process?

A: There is a link above to our Warranty and Claims Process Warranty and Claims Policy (pdf)

Q: How long will it take for delivery?

A: We aim to deliver as quickly as possible. Our goal is 25 days or less for batteries that weigh under 140lbs with crate or packing material. For batteries over this weight delivery time can be 30-60 days depending on the battery model. We find this to be at or above the industry standard, and will strive to shorten the lead time in any way possible.

Q: Will I receive regular updates after my order?

A: You will receive a Tracking number usually about 5 days before delivery (so that’s about 13-17 business days after order according to delivery times shown above), much of the lead time is processing, assembly and customization of the Battery Management System when applicable. Keep in mind most batteries are hazardous rated freight items, so the tracking number might take time to update if the battery came from a freight forwarder before being sent to local UPS or Fedex “hub”.

Q: Do you have 24V, 36V, 48V, 72V or 96V lithium batteries

A: Yes, we can design and build any lithium battery with same standard lead time.

Q: Do you have any lithium batteries made in USA?

A: As of today, there are no LIFEP04 Lithium mines or manufacturers in the USA. Beware if any seller claims that. All LIFEP04 is imported.

Q: How long have you been in business?

A: We have been selling Lithium Batteries, first for solar applications, since 2010.

Q: How can I be sure I am getting a quality product with quality components?

A: Four Reasons: 1) We have the most sales experience with lithium batteries of any other source, simply put 2010 was the start of this technology. 2) Our manufacturing partners are carefully selected (Quality, Service, Warranty Coverage) and they are the largest battery manufacturers in the world. 3) Through our experience we eliminated the elementary issues the often cause problems in a transaction; such as but not limited to product quality. We have already solved many of the common issues that other dealers are just learning about today. 4) We only accept Paypal or Credit Card which is the safest way to buy online, ensuring delivery and quality.

Q: Do your batteries come with a BMS? 

Yes all of our batteries are complete with a Battery Management System. The BMS Functions are: 1. Over charge protection 2. Over discharge protection 3. Over Current protection 4. Short circuit protection 5. Over Heat Indicator (Indicator Only) 6. Balance Cells Function. You might want to consider a battery blanket, some type of heater if you will have an uncontrolled charge source below the recommended operating temperature range.

Q:😡 The Program for the BMS is in Chinese! Do you have an English Version of the Program? 

The program has several languages, to access the English version follow the following button sequence:  fifth button from the top left, second choice on pulldown. Select “English”

OPERATING TEMPERATURE

Lithium performs better in (reasonably) warmer temperatures within the operating temperature range. For 12V 100AH and 200AH batteries the BMS will only offer a high temperature safety warning,  the BMS will not actually stop charge or discharge based on temperature. We do offer custom Battery Management Systems and solutions that will stop charge and discharge based on temperature on larger battery systems and wholesale orders. Please email sales to inquire within. Please Note: It is important to monitor temperatures with your LIFEP04 battery. For cold temperature applications  there are heating options to consider if needed.

TEMPERATURE RANGE

For Charging: 0°C~45°C

For Discharge: -10°C~60°C
