FAQs About OptiMate TM-271 Lithium Charger (12/16V)

Can the OptiMate TM-271 charge both 12V and 16V batteries?

Yes. This professional-grade charger is designed to handle both standard 12.8V (4s) and high-performance 16V (5s) LiFePO4 batteries commonly used in racing applications.

What type of battery chemistry is this charger compatible with?

The TM-271 is strictly for Lithium Iron Phosphate (LiFePO4 / LFP) batteries. It utilizes a specific charging algorithm that ensures safety and longevity for lithium cells, unlike standard lead-acid chargers.

What battery capacity range does this charger support?

It is extremely versatile, capable of maintaining small batteries starting at 2.5 Ah all the way up to large capacity race banks of 200 Ah.

Does this charger offer protection against connection errors?

Yes. It features full electronic protection against user errors. If you hook it up with reverse polarity, the charger will not activate, preventing sparks and damage to the battery or charger.

Is the charging process temperature controlled?

Yes. The Ampmatic microprocessor adjusts the charge current based on the battery's condition and temperature, ensuring a fast but safe charge that won't overheat delicate lithium components.

Special Features:

Battery SAVE mode with BMS reset: starts from 0.5V with continuous monitoring / testing of charge acceptance or bad / shorted cell condition. Unnecessary (and unsafe) charging of a bad battery is prevented.
SafeTº:Automatic charge rate adjustment to ambient temperature sensed at the charger. Reduced charging below freezing, no charging if temperature is below -20ºC/-4ºF (can damage lithium batteries).
Ampmatic: Microprocessor adjusts current to ideal LiFePO4 charge curve to match battery size / condition, for fastest and most complete charge.
Protection against incorrect voltage selection: With 16V selected and a 12.8V (4s) battery is connected OptiMate 7 LFP Select will immediately warn that a low voltage is sensed and then not proceed to charging. USER must confirm the nominal voltage of the connected battery is 16V (5s) before SAVE mode activates. During SAVE mode the charge curve is tracked, if the battery appears to be less than a 5-series 16V battery, it will stop charging.
SAFE: No risk of overcharging. Totally safe for vehicle electronics. Sparks suppressed. Safe for long-term battery maintenance. Automatic shut-down if short-circuited or battery disconnected.
