Product InformationStore Part Number: TPRO-220-1


The TPro-220 is a sophisticated 20 amp, 2 bank battery charger. It can be configured in many different battery system setups, and used as either an onboard, portable, or wall mounted unit. Charging is controlled by an embedded microcontroller that contains software developed exclusively by ChargeTek Inc. This electronic brain insures that all batteries will be fully and properly recharged, regardless of the condition of any one of the batteries it is tasked to charge. The TPro-220 precisely controls charge voltage and current to insure a complete charge every time it is cycled. This charger may be left connected indefinitely to the batteries, maintaining full charge at all times. The TPro Utilizes state of the art high frequency power processing that converts the AC line power to 12 volt DC efficiently and safely. This charger is completely waterproof and sealed with UL approved 94VO flame retardant epoxy. This process provides extreme vibration and shock resistance, and ensures the toughest charger protection possible.

The TPro-220 will direct its current to the battery that requires the most charge. In other words, unlike most other 2 bank chargers, it can direct up to 20 amps to one battery, or 10 amps to each battery and so on. Yes, the charge banks are independent, but this power direction function automatically and efficiently cuts down on total charge time.

This charger is safe for all Flooded and AGM lead acid batteries.
