Drone / UAV / VTOL products in the market often leave customers unsatisfied with quality, durability, and performance. As such, Grepow’s Tattu has always been the first choice of rational consumers as the best drone battery. Here, we will summarize the features of Tattu to our potential customers to help them benefit from the best…
A jump starter is a must-have for every vehicle owner. Without it, you could potentially be stuck for hours waiting for someone to start up your vehicle. So, having a portable solution ready and raring to go is a wise investment. Portable jump starters can get your car up and running without needing another vehicle…
UAV is an actual aircraft that is being commanded via remote control or locally available computers. As part of the UAV system, the battery also needs to be selected according to our needs, such as low temperature, high voltage, high C-rate, etc. Drone batteries come in all sizes, going from hand-dispatched miniature UAVs to enormous…
One of the most sinking feelings any driver has is when they get into their car, switch on the ignition, and – the battery is dead. No matter what they do, they cannot get the ignition to work. The person knows they need to jumpstart their car, they know they should have bought that portable…
The energy density of batteries can be displayed in two different ways: gravimetric energy density and volumetric energy density. The gravimetric energy density is the measure of how much energy a battery contains in proportion to its weight. This measurement is typically presented in Watt-hours per kilogram (W-hr / kg). The volumetric energy density, on…
Battery technology has had to change and develop over the years to keep up with modern technology, such as drones. Semi solid battery, have been known as its high energy density, have been designed and developed to suit high technology appliances today. UAVs and VTOLS, such as those used in agricultural spraying, robotics, for rescue…

Who hasn’t faced the unfortunate situation where their car battery dies and there’s nobody to help. In such a difficult time you wonder why they haven’t invented a solution. The good news is that there’s a solution – a portable car jump starter. There was a time when car jump starters used to be heavy…
The world needs more electricity, preferably in a clean and renewable form. The energy storage market currently consists mainly of lithium-ion batteries. But what can we expect in the coming years? Let’s start with some battery basics. A battery pack consists of one or more cells, each with a positive electrode (cathode), a negative electrode…
The voltage of LiHV battery An L-i-H-V battery is a type of Lithium battery that allows for a higher than normal voltage. The “HV” stands for “high voltage” and it has a higher energy density than standard LiPo batteries. Ordinary LiPo batteries have a nominal voltage of 3.7V and a fully charged voltage of 4.2V….
