ALLOSUN Battery Internal Resistance Meter/Voltage Tester/ Digital Battery Analyzer CECOMINOD062345 Review

The meter worked fine but the meter cables did not have sharp ends as shown in the pictures. They were flat waffle heads which didn't suit my needs.

A very good and precise way for me to control my Lipo batteries. However, the instruction manual was entirely in Chinese. I have emailed All-Sun asking for an English manual but have not received a reply. Instructions would be nice, as would an explanation of the working concept.

It is difficult to stabilize the measurement on the display screen, although battery terminals are constantly checked. I liked that it's affordable and built pretty well. So I'm sad I had to return it for another brand that's twice the price. However, it is an essential tool for any battery assembler.

Excellent value for money. The only downside is that the instructions weren't in English; However, the operation of the counter is intuitive. It uses a standard 1000 Hz signal to determine the internal impedance of the battery. Very easy to use and does not require calibration as the probes are double lead.

Although others claim poor performance, mine worked great. Think if you measure with a rope, mark with chalk, cut with an axe, and check the results with micrometers, you're going to be disappointed. Some shaking but calms down enough to be useful. Don't expect results of 0.00001%. I think it's great for the price and my use to get more information to customize 18650 cells for battery bank customization.

This is an excellent 4 wire Kelvin impedance meter for the money. Good LCD display. Works as advertised. I use the Lacrosse BC-700 to test charge and capacity and this meter to test the internal impedance of the battery. This allows you to sort and match AA flash batteries for the shortest flash recycle time. For more stable readings, place the battery in a good metal battery holder and measure the impedance across the battery holder terminals. The gauge will display 1 when out of range, which…

I agree with the other three reviewers. This counter is garbage. There was no quality control. The counter never worked, right out of the box. After a (tested good) battery is installed, the counter will run through random numbers for about 5 seconds and then lock and display either 1 or -1. This happens in all switch positions, both in volts and in ohms. Turning the meter off does not reset the electronics. The counter shows 1 or -1 immediately after switching on. I can reset the counter by…

Probably the cheapest internal battery ohmmeter on the market but its accuracy is amazing, better than I expected. My top-end iCharger DUO measures the internal resistance of all cells of multi-cell LiPo batteries perfectly, but Li-Ion has a result 10 times higher than normal. Also soldering the #8 caliber leads to the tabs on the battery holder didn't help either. This small pocket device makes it possible - 4-wire lines + 1 kHz measuring pulses are the best solution. The Samsung Li-Ion 18650…
