Am i the only one who collects every possible chemistry of battery he can get his hands on?
@freemo I would if I had run into half those chemistries! I'm a HUGE fan of NiMh though. LiPo is amazing for it's unlimited form factors and unparalleled power density.
NiMh wins in the cold, it wins when it comes to overcharge (which lends to really flexible trickle charging options with tiny solar), it's form factor means you can add it to anything that would take 3 double A's and they are just neat overall.
LiFePo4 however is quickly becoming my new favourite!
