looks too good to be true! Ill wait for some discharge results on the vaping forums :stuck_out_tongue:

Well apparently your beloved HG2 perform almost identical http://www.mountainprophet.de/forum/viewtopic.php?p=5955&sid=fa87c944b949823865a689d8c87a02f7#p5955

so no reason to switch - especially with the price difference

hELLO , I new to this thread I just bought 84 this type of battery But I hesitate about the originallity I buy this battery at local store…

1.When I buy from titan battery.com, the battery have “C” mark, but when I buy at Local store The Mark is “B”,

2.I Set with NIMH operation at the charger, discharge set to 2amp When The Charger begin, it show discharge at 1.4 amp, the voltage drop from 4.2 to 3.88 Volt , this is normal? this is good resistance? I have no graphic, I try with note,

when the voltage at 3.4 Volt, the “Mah” that I got is about 1100 Mah… when the voltage at 3.0 Volt, the “Mah” that I got is about 2300 Mah… when the voltage at 2.8 Volt, the “Mah” that I got is about 3205 Mah… everything is normal?

I did not try The “C” Mark Yet

Discharge with SKYRC balance charger, 2 amp discharge, until 2.8 Volt, I got about 3205 mah

thank YOU, I upload the Picture

It apear to be ok, for a better measurement take a resistor of about 10 ohms and measure the loaded and unloaded

With your numbers the internal resistance 228 mOhms, but the charger is taking into account the wires resistance

measure the 2nd cell too!

Compared to this, looks correct!

2amps - 3208mah

How big battery are you planning to build? It looks like, you could make about 2 batteries of decent size with so many cells… unless it is for ebike

84 / 2 = 42cells per pack… 6s6p (36cells) / 8s5p (40cells) OR go all the way and build 12s 7p…

@arij u might want to read this too:

Maximum recommended constant current = ~7A per cell.
