It's now looking as if Hatchet might not make it to GSL, i fully charged the batteries last night ready for a test this morning, plugged everything in as usual and started getting smoke from one of the batteries, i unplugged the link and the batteries, waited for the smoke to stop and tried again, this time no smoke but the robot seemed underpowered and the batteries seemd to drain very quickly. At this point i'm fully discharging and recharging the batteries and trying again but if it happens again Hatchet's out as i have no spare time or money to get any new batteries.
