Hi everyone. I am new here, but I read a lot of topics here before. I have DIY e bike. I have been used Turnigy Li-po batteries, but they start to be weak. I am thinking about change. I would like to use 26650 5000 mAh instead Li-po. But, no Li-ion is so hard as lipo, as we know, and cut off voltage for Li-ion is around 2.7 V per cell... It is to deep for me, because the speed of bike. But, I would like to order some Multistar battery packs from HobbyKing. But, during last at least half year, there is no sale of this batteries, moreover, they did not offer any Multistar packs for EU market. It looks like, that it finished. Do you have some other verified source of Li-pol cells, which are by quality and price comparable to Multistar? Thank you very much... Sorry for my weak English.
