I was total newbie when I started with e-bikes an couple of years back..and went straight in with LiPo, it is do-able even for a newbie...just be careful, and read the newbie facts about LiPoviewtopic.php?f=14&t=26621
Battery protection and the octopus of wires just got a whole lot easier thank to Patrick (methods) and his parallel/protection kits.http://www.methtek.com/category/battery-protection/
if you were to get his kit boards and your pack was not above 14 series, (so max 58.8 volts) you could create a pack that you can balance charge without dis assembling the pack if you had a Hyperion charger
that does up to 14 series.
the boards from methods do LVC and HVC protection, so they cut out the bike if any cels goes below voltage ( 3 volts I think) The HVC cut out would not connect direct to the Hyperion,but it would cut the charge to the pack if any cell did go above while charging with the Hyperion, if you were not using it for balance charge at the time.
two of his 6s boards would allow you to build a 12s pack of up to 7 parallel, though I guess to start with, 2 or 3 parallel would be enough
4 of these for $45 each = $180, plus two of methods boards 2x $50, plus a bit of extra for wiring....$50 for the main harness would be plenty for cable and plugshttp://www.hobbyking.com/hobbyking/stor ... duct=16803
would give you a 10 Ah pack capable of 150 amps ( 15C ) ..another $90 for 3 parallel and 15 Ah
