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.

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.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.

Love this Dress Shirt
These are my favorite white dress shirts. Unfortunately, not always in stock. Hard to find. Fits comfortably. Easy to wash and almost wrinkle free after each wash. I barely have to iron them. Fabric is thick, not transparent at all but still breathable. Price you pay was set perfectly according to the quality of the fabric.

Dressy Shirt, Casual Price
This slim fit Van Heusen has a fair price, but the feel of a fancy shirt. It's lightweight and has a bit of a glossy sheen. Despite all the negative reviews about the cut being too bulky in the middle, this fits me to a T. I'm pretty slim -- at 6' 140# -- and, while slightly generous in shoulder width and sleeve length, the shirt tapers at the waist very nicely. If tail length is the problem, SHIRT STAYS are a cheap, simple solution. Some reviews also complained about wrinkles. Well, DRY CLEAN -- because yeah, if you're tossing a cotton/poly shirt into a washer and dryer, it will get wrinkly. I pressed the shirt off using an IRON without any problem. In fact, this shirt seemed easier to press than others. Great shirt. Good deal.

Stain Shield Works, But Not Really a Slim Fit Shirt
Good quality for the price. Impressed with the stain shield which actually prevents sweat/wetness from showing... even in extreme heat. No joke. But this is not a slim fit shirt in my opinion. Too much material at the waist with not a lot of length to be able to assist in tucking it all in. Also, I imagine it's the stain shield, but there is definitely a chemical smell to the shirt that survived a few washings. If you're sensitive to that smell, it could be an issue.
