RC CellMeter-7 Digital Battery Capacity Checker Controller Tester for LiPo LiFe Li-ion NiMH Nicd

Another on time delivery. Works well.

This may sound mushy but, I have an Ebike that uses battery packs of 10s x 4-5p configuration. (nothing to do with PlayStation). I’m into building my own packs and have tried and returned several charger and tester’s. All claims to balance packs. Non work with 18650 cells in parallel except this one. My packs are arranged in 5 cells series. I’ve used this tester for several weeks now with out a single error. I charge a pack then balance. This tester brings a 20 cell pack to within .30 volts every time and has auto shut off. Operation is simple, plug in pack, press “type” to select battery type, or press “type” again & hold till it beeps. Come back later it’s done. Easy. THIS IS IMPORTANT!!! NOTE! It seems there are 2 versions of this tester and they look exactly the same. Difference is V1 doesn’t balance V2 does balance. You must read the description. Scroll down to where it says Display and look for the instructions to “balance” For the price it’s priceless.

Very useful battery status reader. This reader helps me understand how much capacity is left for my lipo batteries. Very helpful yool

Light weight and has the features you need. Could be a little more accurate, but it's good enough to know how well batteries are balanced (and charged) in the field. It's become a must in my RC tool box.

I just wanted a voltage meter with 4 positions. This so far is within .02-.03 accurate compared to the Victron MPPT solar controller and battery remote sensor. So instead of guessing if 13.1 or 13.2 per se I can see clearly 13.17 vs my old 3 digit readout guessing if it is higher or lower. I am not relying on SOC readings. Also the unit I just got today 9/4/24 is NOT backlit. Which for me is fine. My wifi-camera reads it clearly when I am not there. So I can "tune in" and check my volts at least remotely. I also have the fridge and 5k BTU A/C units on remote wifi outlets with timers. But at least if I "tune in" and notice super low volts I can remote turn-off those items as well.

Small and inexpensive, it does it's job well.

For gliders this is a must have, it’s accurate, simple to use, and I never had any issues with it, until it just stopped working. Even though I took great care of it, never had it out in wet conditions, checking the voltage on a little receiver battery killed it instantly. It’s a shame though because other wise it was really great

A great tool to test the BALANCED charge on a LiOn battery .....Oustanding.
