Audited Supplier Daly manufacture for fishing machine Liion 3s 12v 40a common port with balance
1. Overview
1.DL3S12V40A bms is used for 3 series 12V battery pack
2.We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc.
3.The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc.
4.According to the customer request we can develop PCM in different sizes and structures.
5.BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle serivce life time.
2. Advantage
1.Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.
2.Strong load ability, constant discharge current 10A/25/35A/45A/60A , use high voltage resistance, low inner
resistance power Mosfet. The heat sink will greatly help cooling.
3.IC itself has power balancing function. The circuit is simple and reliable.
4.Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection
function is very reliable.Long time short circuit of the load won't affect the PCB and the battery.Temperature protection during charging and discharging.
5.Extreme low power consumption. The consumption of the whole device is less than 50uA.
6.PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.

Dongguan Daly Electronic Co.,Ltd was established in 2015, engaging in research and development, production and marketing. Daly professional manufacturing lithium battery protection plate, such as Li-ion BMS, Lifepo4 BMS, LTO BMS. Daly BMS is used in electric vehicles, power tools, energy storage, AGV, forklift.Daly bms specifications are 3 series -32 series, voltage 12V-120V, current 5A-500A.In the last year,Our company research production smart BMS with BT, UART, RS485, Can, LCD, GRS by the vast number of clientsof,Popular in America, India, Philippines, Europe, Asia, North America, etc.Top level for each BMS to market,Welcome field survey to Daly,Looking forward to establishing a long-term cooperative relationship with you.
Q: How do I know what material OR type my battery is ?
A: Please look the battery body,if the normal voltage of your battery shows 3.2V,the battery is LiFePo4.If the normal voltage of your battery shows 3.6V or 3.7V, the battery is Li-ion or Li-polymer battery, You can also ask battery manufacturer for the material of battery.
Q: Is this BMS suit for my battery?
A: This BMS suit your battery or not depends on below 2 points:
How many series you cell is in your battery pack? The BMS you buy must be same series as your battery pack.
What material your battery is? Only the LiFePo4 battery has different electric parameter from other battery, so if you need buy the BMS for LiFePo4, Please let us know firstly.
Q: What is the Common port and Separate port? what is the difference?
A: We take 13S 48V16A BMS as example:
Common port 16A means your charge cathode and discharge cathode are connected in the same point end (our P-), charge cathode and discharge cathode are used in the common connection port, so the charge current and discharge current are same as 16A.
Separate port is separately connected by charge cathode (our C-) and discharge cathode (our P-), so the charge current and discharge current are different, discharge current is 16A, charge current is 8A.
Q: The relationship between battery capacity(AH or mAH) and BMS current(A)?
A:There is no direct relationship between battery capacity and BMS current, big capacity doesn't mean big current, but rely on continue current, that is to say if your engine is powerful, you should choose high current of BMS, it is not relied on battery capacity.
Q: What type of charger should i choose?
A: Lithium battery must choose specific charger, don't use charger for leadacid battery, for leadacid charger may have MOS with high pressure breakdown protection, which will not protect of BMS over charge. LiFePo4 battery charger voltage = number of battery strings X 3.6V, while Li-ion battery charger voltage = number of battery strings X 4.2V.
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 and so on, everything can be talk.
Q: How to contact for BMS?
A: Please send messages at below or E-mail us and we are always glad to help you with BMS.
