Xantrex and Bogart monitors. Those two are good. I ended up on the phone with both at one time or another looking for support. I'm not sure you can get that from GuangZhuo, China.
I'm not sure of this either.
There is a notable difference in accuracy between mono-directional counters Turnigy and Watts Up. There is difference in price too. Both are sold in numerous online stores.
The thing without name from GuangZhuo sells at an auction, not even Buy it Now. Most other items from this seller look very much like bottom-quality digital meters - you know, the kind that reads 12.4 or 12.8 when it's really 12.6. Take your chances if you like, with few hundred dollars worth of batteries.
