Looking for more hill climbing power than I could get from my 10s2p with 26650 Lions(it works great on flat ground) This new project is a 10s1p using Turnigy 2s/5000mah/60c hard packs from Hobby King 5 Packs wired in series is smaller and 2lb lighter than the Lion pack! https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=52279 I used these jst extension wires to extent the balance wires to the bms: omitting the black ground wire and using only the pos wires from cell 1 and 2 of each pack. I did this instead of hard wiring to allow for easier testing and replacement of individual cells I attached the packs to the deck with servo tape.
Hard wired the packs in series for better power transfer and to reduce bulk. Using adhesive lined shrink tube and squeezed the ends to close it up.
I decided to keep the balance lead connectors for easier testing and replacement of individual packs.
I took it for a quick test ride with only 38v on the pack. Powering up a 12% grade the voltage sag was no more than 1 volt. More test results to follow…
