How long will a KHLiTech® battery last ?

KHLiTech® advanced lithium-ion technology can give you with 3000 complete charge and discharge cycles at eightieth DoD (Depth of Discharge). once 3000 cycles, you may still have over eightieth of usable energy left. just in case you discharge KHLiTech® at sixty fifth DoD rate, you’ll be able to expect to urge 5000 cycles.
● Example 1: KHLiTech® 12V-100Ah battery, once being discharged at eightieth DoD for 3000 cycles, is currently a 12v 80ah battery.
● Example 2: One KHLiTech® 12V-100Ah, once being discharged at sixty fifth DoD for 5000 cycles, is currently conjointly a 12v 80ah battery.
In term of your time period, If you discharge eightieth of the KHLiTech® and so recharge it on a daily basis, seven days every week for height years, you may still have eightieth of usable battery energy left. this can be an outsized increase in period of time compared to a traditional Lead Acid battery (AGM, Gel) rated at five hundred cycles for five hundredth DoD cycles.

What's the Grade A Lifepo4 lithium battery?

Grade A:Battery cells made completely according to the standard of the orginal manufacturer.
Grade B: Cells under-perform or have other defects.Usually the efficiency of the grade B cell is 80%~90% of that of the grade A cells.
Grade C: Batetry cells are used, swelling, salvaged, or damaged.Grade C batteries are below average in every way.

For more details, please refer to: The diffeerence between Grade A Battery and Grade B cells

What is the Battery Management System (BMS) and the way will it work ?

Each KHLiTech® embeds a inherent BMS. This BMS could be a advanced style that manage 2 main aspects of battery throughout operation :
Protection options :
● Low Voltage Protection Switch – mechanically disconnects at 10.0V
● Over Voltage Protection Switch – mechanically disconnects at 14.8V
● Short Circuit Protection Switch – mechanically and safely disconnects battery
● Reverse Polarity Protection Switch – mechanically and safely disconnects battery
● Over temperature – mechanically shut-down battery till traditional temperature recovery
Balancing options :
● Internal cell reconciliation – mechanically balances Keheng® cells throughout battery operation. reconciliation algorithmic rule has been developed to confirm excellent balance between cells throughout battery life.
● Charge reconciliation – for Keheng® connected in parallel and/or nonparallel, the BMS can balance every Keheng® severally, so as to produce a perpetually balanced battery system.

How do I charge a KHLiTech® Lithium-ion battery ?

KHLiTech® uses the most recent and most advanced intrinsic battery management system (BMS) to watch and stop injury to the battery throughout use. you will utilize a Lead-acid charger with KHLiTech® Lithium battery, however some customers prefers employing a Lithium charger to stay a much better life.
Several charging sources area unit possible:

● Alternator: Most alternators (marine, RV, cars) can with efficiency charge KHLiTech® lithium ion technology as before long generator charge voltage is between 14.0V and 14.6V (for a 12V battery)
● Conventional lead-acid accumulator charger: KHLiTech® Battery Management System (BMS) is intended to be compatible with customary chargers. you would like to ascertain that charger encompasses ainherent CC/CV charge algorithmic rule (Constant Current / Constant Voltage) and charger most voltage is comprised between 14.0V and 14.6V (for a 12V battery)
● Lithium-Ion charger: this can be the simplest thanks to charge Keheng ® Lithium-ion battery. These chargers embeds some dedicated charge algorithmic rule with precise charge voltage. It conjointly manage with efficiency charge floating voltage and period so as to maximise battery life.
