yopappamon,

The no charge for shipping only applies when you buy a battery "package," i.e., battery and charger. If you only ordered batteries, you'll get an e-mail indicating what you owe for shipping (it's reasonable--my shipping fee was only $15). I would suggest that you get the CellLog 8 to monitor discharge and charging (in lieu of a BMS). I have one and it's amazing how much information it provides. http://epbuddy.com/index.php?main_pa...5vqe6vl4v2jdn2 (Clearly, if you have more than a 24V (8 cell) battery you may need more than 1 CellLog since it can only monitor 8 cells.) You can get a pre-made connector off ebay for $14. http://cgi.ebay.com/Chargery-Power-D...item3ef9488a10
With the Chargery cable, you could actually use an iCharger 1010B or 208B to charge your battery since the Charger cable is 100% compatible with those Lithium smart chargers.
