Anyone who has/ knows of good accurate watt meters that will let me know when my batteries are running low, post the links. Most of the ones I see on here people say fail after a short period of time or are not accurate. Would love to know who has decent ones and where I can get them.
 
Voltage range? Current range? Budget range?
 
The Watt-hours measurement on my GT meter from eBay is way off. The current and Amp-hours seem alright but the voltage isn't very accurate. There seems to be a few versions including some that can be calibrated. There's a thread with replacement firmware around somewhere.
