I've placed this here to warn otherpower/forcefield users of a threat to their wallets. The first thing is if you detect ANY errors on the specifications of the intended purchase, they are sure to become contentious (you will lose) in the future. It might be "bait and switch" or the reverse, that is, the substitution of an inferior battery for the one expected (of course at the higher price). As I've said before NiFe was THE original Edison cell and the technology is not changing much so the advertised weight of a cell is extremely important. The guts of a cell can vary so the volume is not as important. If the seller/importer send you a lighter battery you've been gypped (sorry for the reference to gypsies, I know a few good ones). If they say the battery can provide 661 amps over 100 hours and the battery is 500 amp rated at a c5 discharge (over 5 hours) there is very high doubt that you will get a fair deal. If they suggest you should be happy with a reduced shipping rate because the cells are lighter, you are being conned. If you don't check the ripedoff site and the BBB in advance it's a mistake. Insist on independent references of satisfied customers unless you are a personal friend of the CEO.
On the plus side I believe Changhong and Changzhou NiFe cells are of high quality and reliability. These companies want to provide the world with good batteries after China gets theirs :-)(I've heard they are making over 20,000 NiFe wet cells a quarter). My purchase included chemicals, hydrometer, thermometer, apron, goggels, gloves, and a good multimeter I'd probably have to pay over a centibuck here in the US for. The crating/banding was good...no damage. Overall weight was about 2500 pounds in 5 crates (3 at 550 pounds-10 cells each). More to follow......
