HOW DOES LITHIUM-ION STACK UP AGAINST LEAD-ACID?
PROMISING INDUSTRIAL APPLICATIONS
Lithium-Ion (Li-Ion) battery technology has emerged as a challenger to traditional lead-acid batteries in industrial applications. Which battery makes sense for you? It depends on your application.
WHAT ARE LITHIUM-ION BATTERIES?
Sealed batteries that retain their charge capacity for thousands of complete charge and discharge cycles1
3A family of battery technologies that use Li-Ions to store energy

Longer run times
Tolerates high shock & vibration environments
Four times lighter and three times smaller
Can be left partially discharged
No maintenance
Higher power capability
Fast charge capable
Higher cycle life
2 Lightweight, rechargeable, high energy density batteries
Prices should continue to drop with maufacturing economies of scales and incremental technologies improvements. Li-Ion is currently 4-5x more expensive than lead-acid but has a better total cost of ownership (TCO) in some applications.

CELL QUALITY
Not all Li-Ion batteries are equal. The cathode material used in Li-Ion batteries gives them their unique temperament. High quality, low variability manufacturing controls must be used for cell assembly
BATTERY MANAGEMENT SYSTEM (BMS)
Use and approve a BMS that can disconnect the cells or stop their charge/discharge
Consists of well made cells, a battery management system, and an intelligent charger. How do you do that? See below.

PACK INTEGRATION
A holistic risk management approach to the battery pack will design in safety at every level of integration. Consider cooling, interconnects, electrical insulation and packaging
SAFE AND SMART CHARGER
Delta-Q’s IC Series Industrial Battery Chargers are capable of charging both lead-acid and Li-Ion battery packs. Delta-Q works with major battery manufacturers to ensure safe operation of the battery and charger systems. Additional capabilities include support for CAN bus communication and customizable charging algorithms for motive applications.
By choosing a flexible charger, you will have the ability to use the same charger even if the battery type changes (lead-acid to Li-Ion)
An appropriately designed BMS is a necessity when lithium-ion is involved.“

HOW TO SELECT A LITHIUM-ION CHARGER?
Pick a charger that will accurately recharge the batteries Voltage accuracy means you always get to 100% charge.Control accuracy means the charger responds appropriately to given commands.
2Pick a charger as smart as your batteriesBatteries are getting smarter with integration of CAN bus, USB, Modbus, and more. A charger that can connect to a BMS will form a robust system. Working together, the charger and BMS will keep you informed on your machine’s performance.
