Vt133 inaccurate battery meter

Hi guys. I'm having a couple of issues with my vt133. My battery meter reads a max of 95% after a full charge on hg2 batteries. I've set up the on the watts hours calculator according to the battery and tried another fresh set of the same batteries. The mostly annoying thing is the mod reads 70% battery then I pick it up 5 mins later and it's showing 40% How can I remedy this? Really appreciate any advice.

the calculated wh value is always too high. you need to run battery analyzer for an ACTUAL WH capacity or find a csv battery curve for 2 HG2's. for example. 7.4v at 3000mah = 22.2 WH's (calculated) when in reality it's closer to 17-18 WH's the dna 133/200 actually can use. cell soft cutoff is also a determining factor on how much capacity (WH) you can get out of your batteries. 
maximum charge voltage is also dependent on whether you choose "max puffs" or "max recharges" (4.20 and 4.10 respectively)
basically, too high of a WH and the battery gauge will never show full (%100)
