Full models are as follows:

Why lithium-iron-phosphate?
Lithium-iron-phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. The nominal voltage of a LFP cell is 3,2V (lead-acid batteries: 2V/cell). A 12.8V LFP battery consists of 4 cells connected in series; and a 25.6V battery consists of 8 cells in series.

Service life
LFP battery does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of LFP compared to lead-acid. Other advantages are the wide operating temperature range, excellent cycling performance, low internal resistance and high efficiency (see below).

Efficiency
In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance.
The round trip energy efficiency of a LFP battery is 92%.
The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached, resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy is required (battery operating in 70% to 100% charged state). In contrast, a LFP battery will still achieve 90% efficiency under shallow discharge conditions.

Cell balancingand and monitoring
LFP batteries have integrated cell balancing and cell monitoring. Up to 5 batteries can be paralleled and up to 4pcs 12V batteries or 2pcs 24V batteries can be series connected,so that a 48V battery bank of up to 1500Ah can be assembled. The cell balancing/monitoring cables can be daisy-chained and must be connected to a Battery Management System (BMS).

Battery Management System (BMS)
BMS Function:
1. Disconnect or shut down the load whenever the voltage of a battery cell decreasesto less than 2,5V.
2. Stop the charging process whenever the voltage of a battery cell increases to more than 4,2V.
3. Shut down the system whenever the temperature exceeds 75°C.

Company advantages:

YM Power Tech Limited is a professional lithium-ion batteries supplier that offers custom-made services for different specifications of lithium-ion battery packs and system integration. Of course, lithium-ion cells, BMS chargers, etc can be supplied as well.

YM is our brand. YM has two meanings. That is Yoctometer(ym) Tech Powers Yottameter(Ym). Although Yoctometer tech now is hard to achieve (the most advanced level now is Nanotech), powering yottameter is much possible. Our aim is to use the most advanced technology to make the best lithium batteries.

YM's lithium batteries are widely used as power batteries for different kinds of electric vehicles, such as electric scooters, electric cars, electric motorcycles, AGV, golf carts, electric wheelchairs, etc. Besides, YM lithium batteries are also applied as storage batteries, such as for home solar storage systems, backup power supply, UPS, solar street light, RV, etc.

Except for pure lithium batteries, YM also offers solutions to the complete EV powertrain kit and the complete energy storage system, including not only lithium batteries but also motors, motor controllers, charge controllers, inverters, etc. OEM & ODM services are offered.

YM's products have won many national invention patents and some products have passed the CE certificate. At present, YM has cooperated with many low-speed electric vehicle manufacturers in China.

By 2019, YM has built an R&D center, domestic sales office, and production factory. Production factory covers an area of 2000+ square meters with 1 manual production lines and 1 automatic production line. The annual production capacity can reach 1GWh. The factory has got ISO9001 quality management system certified and ISO14001 and OHSAS 18001 certified.

In 2020, YM started to develop overseas business. It is believed that YM will do a good job in the international market!
