I divided currents by 4 and 8 so that we can see some detail. As for the improvements in test gear: Application Battery Energy Storage System.

This feature enables the user to operate the sl;b cells under extreme environmental and operational conditions. As for the Kokam battery: Notify me of new posts by email. LTO cells can also be re-operated after an event of an over-discharge, unlike conventional graphite based Li-Ion cells.

With Kokam patented cell internal structure the Kokam produced cells belong to the largest size both dimensions and capacities Lithium cells.

Kokam produces large scale of Lithium-polymer cells. It is suitable for extremely volatile and dynamic operational conditions.

If you continue to use this site we will assume that you are happy with it. These cells can be used as emergency power supply batteries, energy storage system for fotovoltaic power plants, large scale energy backup systems in electric power distribution, backup electric supply in facilities where the continuity of electric energy supply is crucial.

UL for all types of cells. Upon 25 years of accumulated field experience, Kokam have supplied aggregate of over MWh battery system around the world. But also new hardware for the electronic load, so testing conditions have improved.

Cell specification 65Ah Remarks Capacity Ah 65 0. For further technical details, price quotation, delivery conditions, actual stock pieces or lead times, please contact us via our contact form.


With no memory efect they have singnificantly longer lifetime than lead acid, gel based or Nickel based NiCd, NiMH batteries usually used in these devices. The heat dissipation is also correlated with safety. Advantages of Kokam Lithium Polymer Battery. We use cookies to ensure that we give you the best experience on our website.

Silverclean design by Iceable Themes. Proudly powered by WordPress. The battery cell is the basis of an Energy Storage System. With capacities from 20 Ah upto Ah and current supply upto A permanenty or A in peaks below sopb these cells represent absolute top products on Lithium-Ion battery market. But have a closer look at the numbers: It also looks like the pack is dying cycle over cycle.

Capacity decreases each run — mAh, mAh and mAh respectively the exact mAh steps might be a coincidence. The cells also show very low slb resistance, which is more than an order of magnitude lower than mine. So for higher currents where contact resistance and also wire resistance plays a role, current regulation seems to become a bit less stable, but overall performance stays consistent.

These cells are mainly used for static applications of whichever energy storage systems where the maximum energy in minimum space is needed to be stored in very reliable and effective way.

Thanks to this feature the cells add minimum weight to any portable device. At 8 ampere, the voltage regulation seems to be much better, but the current regulation shows a slope. Kokqm the former test, current went up from 3. It might be gassing cells, but I found the weakest cell is actually 3.

A thermal runaway event is significantly less likely to occur in LTO cells. Compact High Energy Density cells are small size cells in industrial scale. With capacities upto 20 Ah these cells are suitable for many applications of portable electric and electronic devices in many professional areas IT, telecomunications, medical, military, aviation, navigation, radio comunication, instrumentation, laboratory devices etc.

I never made it to stop the tests before the hard 3. These cells are destinated for any application where an extreme power from very low weight battery is required they can supply upto 35C permanently and 50C in peak below 10s. Large High Power cells are the genuine Kokam products with amazing absolute power supply values. A key factor in maintaining optimum performance is to keep the cell temperature within the designed range.

Large High Energy Density cells with capacities from 20 Ah upto Ah are the genuine Kokam products with the maximum energy density per kilogram on the market.

Kokam Lithium Polymer 5S mAh 30C battery (WHL #30) – Wan Hung Lo Electronics

With such performance these cells are mainly suitable for applications in electric and hybrid vehicles of any size starting from electric bikes, scooters and motorbikes upto high performance electric cars or large scale transport vehicles trucks, busses trains etc.

Still, amps at 18 volts is more than 2kW, which is quite a thing for a g battery pack…. Have a look at the blue curves in the graph above, where the battery was tested with the upgraded version of the electronic load.

Wan Hung Lo Electronics. Yes, I double-checked colors — last time, there was a steady voltage but rising current. The performance of Kokam Lithium polymer battery surpasses the other existing batteries in the market today.
