OptiMate Lithium Battery Charger TM-271

Professional OptiMate battery charger for 12.8V and 16V Lithium batteries. (Plug type is USA 120V.) The Optimate TM-271 is perfect for high performance 12.8V (4s) and 16V (5s) LiFePO4 / LFP batteries that demand fully automatic, fast and accurate temperature controlled charging. Perfect for 12.8V / 16V LiFePO4 / LFP batteries sized from 2.5 to 200 Ah. Features a Power-Saving stand-by mode and Full electronic protection against errors. 3-year limited warranty.

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.

Cute but could use some pockets
Special Size: 6" Inseam Contrast Trim without Pockets, Size: Small, Color: Navy/White
Obsessed with these shorts. They are so cute and comfy. They fit true to size and I love that there is a matching top you can buy separately. I feel like the material is pretty thick and I don't have to worry about it being see through. My only complaint is that there are no pockets.

Nice fabric
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Taupe
These are well made. The fabric is perfect! Not thin. I was disappointed that I ordered a size that was too large. I had to return. I need to get updated body measurements before reordering.
