Project Slash – LiPO and spring preload changes

The next step in the Slash project was to add a LiPO battery into the mix. The XL5 ESC is compatible with 7 cell NiMH batteries, or up to 2S LiPO batteries. The switch over is trivial: turn it on, then press and hold the power button for about 12 seconds and it will switch from red to green. This enables the low voltage cutoff (or LVC). Without the LVC, the LiPO battery can discharge too much, and that can ruin it (as in, it will no longer hold a charge), or even catastrophic failure (as in a fire – if you google “lipo fire” you will find some scary videos).

Plenty of instructions and guidance on the web for this, but I have some learning to do first. I never really had an electronics bug. Sure, I know the mathematics, and what the components do, but wiring shit up? Not really. Continue reading →
