More than 2000 cycles, C-rating is 3 – one 48V50AH module can output 150A continuosly.
Quadcell Easily parallel link up to 4 battery modules to form a larger capacity battery bank. Can use 2 such hubs to link up to 8 battery modules. Each battery module is light weight for one person to carry around – around 27kg. Each module has its own built-in BMS and charger.
During charging process, a conventional Li-ion Battery containing lithium cobalt oxide (LiCoO2) needs two steps to be fully charged: step 1 is using constant current (CC) to get 60% State of Charge (SOC); step 2 takes place when charge voltage reaches 4.2V, upper limit of charging voltage, turning from CC to constant voltage (CV) while the charging current is taping down. The step 1 (60%SOC) needs two hours and the step 2 (40%SOC) needs another two hours. LiFePO4 battery can be charged FASTER by only one step of CC to reach 95%SOC or be charged by CC+CV to get 100%SOC. The total charging time will be two hours.
A LiFePo4 is also safer. A LiCoO2 battery has a very narrow overcharge tolerance, about 0.1V over 4.2V of charging voltage plateau and upper limit of charge voltage. Continuous charging over 4.3V would either damage the battery performance, such as cycle life, or result in firing and explosion. A LiFePO4 battery has a much wider overcharge tolerance of about 0.7V from its charging voltage plateau 3.4V. Exothermic heat of chemical reaction with electrolyte measured by DSC after overcharge is only 90J/g for LiFePO4 verse 1600J/g for LiCoO2 . The more is the exothermic heat, the larger energy heating up the battery in its abusive condition, the more chance toward firing and explosion. A LiFePO4 battery can be overcharged up to 30V without protection circuit board. It is suitable for large capacity and high power applications. From viewpoint of large overcharge tolerance and safety performance, a LiFePO4 battery is similar to lead-acid battery.
Alike lead-acid battery, a number of LiFePO4 cells in a battery pack in series connection can balance each other during charging process, due to large overcharge tolerance. This self balance character can allow 10% difference between cells for both voltage and capacity inconsistency. Large overcharge tolerance and self-balance character of LiFePO4 battery would simplify battery protection and balance circuit boards, lowering their cost. One step charging process would allow to use simpler conventional power supplier to charge LiFePO4 battery instead to use a expensive professional Li-ion battery charger.
It is detrimental to have a LiCoO2 battery working at high temperatures, such as 60C. A LiFePO4 battery runs better at elevated temperature, offering 10% more capacity.

This GC2 sized replacement battery, 48V30Ah 15.6 kg, was designed specifically for golf cars, utility vehicles, LSVs and AGVs.
InSight batteries are drop-in ready and easy to install, just connect them in parallel for the capacity you need, up to 300Ah. InSight batteries feature an elegant BMS that provides precision balancing within a battery and between batteries in a parallel system without the need for charging batteries individually. In addition, our proprietary software determines and manages regenerative currents – unlike any other battery solution – avoiding unnecessary battery disconnects. These batteries are truely state of the art “smart batteries” with on-board management and SOC indication.
RELiON lithium batteries typically weigh one-third less and provide up to 50% more energy than traditional flooded, AGM, or GEL lead-acid batteries, and they provide more power. RELiON lithium batteries offer super-low resistance (and 99% efficiency), allowing much faster charging, with minimal losses. Lead-acid batteries lose power quickly during discharge. Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge. Lead-acid batteries typically provide less usable energy with higher rates of discharge. They are usually limited to 50% of the rated capacity to prevent diminished life. Rechargeable RELiON lithium batteries cycle 5,000 times or more, and higher rates of discharge minimally affect cycle life. Lead-acid batteries typically deliver only 300-500 cycles, as higher levels of discharge greatly reduce cycle life.
