Its main object is a secondary battery,mainly to improve the battery utilization rate, to prevent excessive battery charging and excessive discharge, which can be used in electriccars, battery cars, robots, unmanned aerial vehicles.Detail imagesCertificationsPacking&ShippingThe lithium battery is Dangerous Good for shipment by Sea and By air and they should be shipped under the regulation of UN3480. All EVLbatteries are packaged by DG plywood case and we provide UN38.3 test report and MSDS.Please check shipping cost before place order, the lithium battery is Dangerous Good, the shipping cost is very different, so please check shippingcost before place order.Company Introduction EVL Battery Limited is a leading NCM Lithium Battery manufacturer from China and its public company in the Hongkong Stock Exchangemarket. There are 4 factories in Fujian and Guangdong. The production capacity of 4 factories is as much as 20 GWh per year. EVL BatteryLimited is the number one Lithium Battery manufacturer from China.Our Services & StrengthWe provide high-quality EVL Battery to clients all over the world and help clients deliver batteries from China to them by sea and by air at areasonable price. And we provide the necessary technical support and warranty to you!FAQQ: What is the life expectancy of a Lithium battery?A: The typical estimated life of the Lithium Iron Phosphate (LiFePO4) battery is 5-15 years or 2000 to 8000 charge cycles. One charge cycleis a period of use from fully charged, to fully discharged, and fully recharged again.Q: If I want to solar charge LiFePO4/Lithium Ion battery, which already has PCB, would a normal SLA controller work fine?A: For LiFePO4 / Lithium-Ion battery, we always recommend using the LiFePO4/Lithium-Ion solar controller. Especially if you are using the batteryas UPS (backup power supply). The Lead-Acid solar controller will constantly provide pulse current to the battery, in the long run, it mightdamage the PCB. So the PCB won't be able to protect the battery when it should be.Q:I am a distributor. Can I cooperate with the battery warehouse for a long time?A: Yes, Individual pricing for large scale projects and wholesale demand is availableQ: Why hasn't my ups or FedEx transportation number been updated?A: This is normal, in countries with tariffs, our packages need to pass the customs of your country before they can be delivered to the localUPS or FedEx. Once they pass the customs and update the transportation number, you can usually receive the goods within 3-5 days.Q: Are the cells I bought balanced? A:We know the importance of maintaining the consistency of each cell in the battery pack, so we will match and balance all cells to ensurethat the internal resistance, voltage, and capacity of cells are completely matched and balanced before delivery. This process is very necessary

Waterproof Li-ion 10S BMS 36V 30A Battery Management System For 3.7V 10 Cells Lithium Battery Pack Model: DL 10S (3.7V rated Li-ION Battery not for 3.2V Rated LiFePO4)common Version : common port for charge/discharge separate Version : separate port for charge/discharge We can customize any PCB from 3S to 32S lithium batteries with different current.1. Overview1.DL 10S 36V 10A/15A/20A/30A/40A/50A/60A/80A/100A/120A/150A/200A/250A bms is used for 10 series 36V battery pack2.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. Advantage1.Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.2.Strong load ability, constant discharge current 10A/15A/20A/30A/40A/50A/60A/80A/100A/120A/150A/200A/250A,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 protectionfunction 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. 6.PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating Packaging & Shipping Company ProfileDongguan Daly Electronics Co., Ltd. is located in Dongguan City, the world factory. It is a high-tech company specializing in the development of lithium battery management system solutions. Daly people are based on quality, technology as the core, innovation as the soul, and customer-oriented.

The group has more than 20 several senior engineers specializing in the battery management system industry for decades ,they are dedicated to product research and development. One-stop solution, Lithium / LiFePo4 battery packs, accept customized,OEM and ODM sevices, Any questions please contact us!We will respond within 1 business day or less. Our Services & StrengthWe are the BMS manufacturers, can provide customized services; We are specializing in provide reliable and stable BMS solution and program; our company has complete product line, guarantee delivery in time. 1.What is the common port and separate port?what is the difference? We take 13S48V15A BMS as an example, common port 15A 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 the same 15A. while the separate port is separately connected by charge cathode (C-) and discharge cathode (P-), so the charge current and discharge current are different, discharge current 15A, charge current 8A. 2.What is the balance function?The working principle and function are as followings, when your one cell voltage is upto alarm voltage(Li-ion upto 4.18V, Life Po4 upto (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 30ma(when balance discharge starts to work, BMS will starts a little heat up, which is the normal reflection), the cell is in both charging and discharging status, and others which are not reached to alarm voltage(Li-ion 4.18V, Life Po43.6V)are only in charging status, no discharging, when the fast cell voltage is reached to alarm voltage (Li-ion 4.25V, Life Po43.75V)BMS starts off power protection, all the other cells are all in stop of charging, this process will enable your battery charging in balance current, and your battery voltage are in balance status, but when your cell voltage difference are in a big range, then balance can not be functionning. well 3.The relationship between Battery capacity and BMS current?There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery, but rely on continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery capacity. 4. What type of charger should I choose?Lithium battery must choose specific charger, do not use Charger for Leadacid battery, for leadacid charger may have MOS with high pressure breakdown protection, which will not protect of BMS over charge. Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V. 5. What current BMS should I choose ?Take 10S36V as an example: what current BMS you choose is relied on your E-bicycle Motor power and current limitation of controller. eg., choose 15A for below 350W, 20A for below500W, 30A for below 800W, 60A for Below 1000W, higher than 1200W are contact with our service specialist for suggestions, one inall, continue current shall be higher than current limitation in Controller. 6. Whether my BMS damaged?if you want to judge if the BMS is damaged, please take the folowing steps, to test if each cell voltage is the same with voltmeter? if the cell voltage difference is over 1.0V, the fault is displayed that it cannot run far, no power supply at the start range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displyed as no charge, no discharge, no discharge while the battery has voltage.
