The CellMeter-8 has all of the features of the CellMeter-7, but also adds new features namely a ESC / Servo Tester, Storage Discharge Function and a Backlit Display.
The addition of the ESC / Servo Tester is really useful; for the drone builders you can use it to spin up your motors to check spin direction without havening to use a FC or receiver. For those into planes you can use it to check servo throws and set the neutral point.
The discharge function can be used to balance store LiPo batteries. Simply set your end voltage and leave your battery plugged in to storage charge it. The discharge rate is 1Amp.
As with the CellMeter-7, the CellMeter-8 can check all different battery types and will measure the voltage of both individual cells and full battery voltage. It can also indicate the highest voltage cell, lowest voltage cell and difference between, as well as display the percentage of battery capacity remaining.

- High visibility LCD display screen

Questions and answers of the customers

A LiPo alarm / tester is a must have piece of equipment for any flight box. LiPo batteries require careful management to maximise their life; they can be charged up to 4.20V and discharged down to 3.0V per cell. Any lower or higher in voltage and the cell will almost certainly be irreversibly damaged (reduced capacity or total inability to accept a charge). Furthermore, a damaged cell may become unstable which can be very dangerous (increased fire risk). A LiPo alarm / voltage tester is therefore an essential piece of kit to monitor the status of your individual cells and avoid damaging them.
Most pilots who fly without a telemetry feed use a LiPo Alarm on board their craft to alert them as to when it’s time to land – it’s recommended to set your alarm to 3.6V to give you enough time to land safely.
