Decided On Batteries.

So I have decided to go with a different battery package.. Since the old one only had balancers for each single battery, and did not interfere with the charger or stopping one from receiving too much charge. Thus I am going to buy this package which includes bms too:http://elitepowersolutions.com/products/product_info.php?cPath=27_29&products_id=111

Mainly because they come with a proper bms. But also because they are around 7lbs lighter which is pretty crucial. Another advantage with these is that they have a 3c discharge rate continuous, compared to the others 2C. They have the same kwh and voltage ranges etc. The weight difference should really be helpful. I'll probably be doing some ordering and work on the bike this weekend. Need some wire etc.

The website says this:

Advantage of GBS 2nd Generation Li-ion Batteries Compared To Thunder Sky Batteries:

- 10% higher energy density by weight and by volume;
- Superior safety performance due to patented new safety valve and pressure cap designs;
- Batteries do not explode or catch fire when batteries are shorted or punctuated resulting in internal shorts;
- More robust connection due to new electrode terminal design using four rivets or four screws per terminal; Prevent loose connections caused by vibration;
- Reduced impedance due to improved electrode terminal design;
- Improved cycle life;
- New cell structure better facilitates BMS integration and battery pack formation, and improves air circulation.
