Paul,
This is a recommendation for 900 ma (or less) chargers. The higher setting on the supplied charger, produces a lot of heat. I have had reports of teams attempting to use chargers of much higher current. Standard charge for these batteries is normally stated at 1/10 C to 1/3 C or 300 ma to 900 ma for a 5-10 hr charge cycle. Chargers have been reported at some events at currents in excess of 3000 ma. Without temperature feedback from the battery to charger, which is not provided by the Tetrix battery, these chargers can be dangerous as excess gas builds up and temperatures reach the point where burns may occur.

Adam,
The minibot battery can only be repaired with identical components as all other electrical devices.
