About the battery BMS

Function: Detect and protect the battery from over-charge  ,over-dicharge, over-current short-circuit temperature detecting protection  and auotmatically voltage balance function . Build with high end electronic components (High End IC and MOSFET ) ,simple structure design will let it have more stable quality working performance , Flexible application ( it can be used for less series battery by leaving some connection pins at empty status ),full set of protection measures let it works well without any infulence from external unexpected accidents.

Shenzhen Li-ion Battery Bodyguard Technology Co.,Ltd was founded in 2013.
Mainly provide Battery PCM & BMS for Lithium ion ,Lifepo4 ,LTO battery pack.

Since 2013, the company has more than 400 types of hardware PCM/BMS,and software BMS including  HDQ/12C/SMBUS/RS482/RS232 & Bluetooth and so on.

Mainly covers battery assembly 1S-35S in series ,working current up to 350A;
the products are widely used in solar street lamp,golf ,LED light,power tool,electric bicycle,medical equipment,EV application......etc.

Shenzhen Li-ion Battery Bodyguard Technology has passed ISO 9001 (2015) certification.The company was awarded High Technology Expertise (HNTE) in 2018.

Products certification has ROHS,CE,UL...etc.

FAQ

Q: How do I judge what material my battery is ?
A: Please take a look at the battery body.if the normal voltage of your battery shows as 3.2V,the battery will be LiFePo4.If the normal voltage of your battery shows as 3.6V or 3.7V, the battery will be Li-ion or Li-polymer battery. you can also ask battery manufacturer the material of battery.

Q: Can I use this protection circuit board for my battery?
A: Can use this protection circuit board, or not?
There are 2 questions:
How much cells in series is your battery pack?
The protection circuit board you need to buy must be same cells in series as your battery pack.

What material is your battery?
Only the LiFePo4 battery has different electric parameter from other battery, so if you need buy the protection circuit board for LiFePo4 battery , Please let us know firstly.

Q: Do we need cell balance or not?
A: The function of balance : Since battery is made of many pcs of cells in parallel and in series, the cells can't be the same as no two people in the world is the same , so can only put in group with similar performance is not
without balance function

Q: Do you have Minimum Order Requirement (MOQ)?
A: No, We don't have MOQ, Different customer have different requirement ,We can provide various capacity and size as per your requirements,Also ODM / OEM is welcome.

Q: What is your term of payment?
A: PayPal, T/T, L/C,Western Union

About your products,just tell us the relative voltage/ cells/ current A or equipment etc,we will help to recommend the most suitable products for you.
