The Smart BMS CL 12/100 is a Battery Management system for Victron lithium-iron-phosphate (LiFePO4) Smart Batteries. It has been specifically designed for 12V systems with a 12V alternator. The BMS CL 12/100 monitors and protects each individual battery cell within the battery (or battery bank) and will disconnect the alternator charge sources or DC loads in case of low battery voltage high battery voltage or over temperature.

The dedicated alternator input provides current limiting and one-way traffic from the alternator into the battery this so any size alternator (and start battery) can be safely connected to the Smart Lithium battery or batteries. The BMS is also equipped with a remote on off connector to turn the BMS (and the system) off via a remote switch and a pre-alarm contact to give a warning signal before the BMS will disconnect the batteries from the system.

Battery Management system - The BMS connects to 12 8V Victron LiFePO4 (LFP) batteries. Up to 5 batteries may be connected in parallel. Can be used as a system on/off switch.

Alternator and battery protection - The input current is electronically limited to approximately 90% of the fuse rating. A 100A fuse for example will therefore limit the input current to approximately 90A.

Choosing the right fuse will:

  1. Protect the LFP battery against excessive charge current (important in case of a low capacity LFP battery).
  2. Protect the alternator against overload in case of a high capacity LFP battery bank (most 12V alternators will overheat and fail if running at maximum output during more than 5 minutes).

Starter battery Protection - This function is similar to that of a Cyrix Battery Combiner or Argo FET Battery Isolator. Current can flow to the LFP battery only if the input voltage (= voltage on the starter battery) exceeds 13V. And current cannot flow back from the LFP battery to the starter battery thus preventing eventual damage to the LFP battery due to excessive discharge.

Li-ion battery protection - Excessive input voltage and transients are regulated down to a safe level. The Smart BMS CL will stop charging in case of cell over voltage or over temperature. It has three outputs similar to the miniBMS:

Load Disconnect output - The Load output is normally high and becomes free floating in case of imminent cell under voltage (default 2 8V/cell adjustable on the battery between 2 6V and 2 8V per cell). Maximum current: 10mA. The Load output can be used to control the remote on/off input of a Battery Protect inverter DC-DC converter or other loads.

Pre-Alarm output - The pre-alarm output can be used as warning when the battery voltage is low and it will trip shortly before the Load Disconnect output is disabled due to cell under voltage. The pre-alarm output may be used to drive a relay LED or Buzzer. It can be configured as continuous or intermittent signal. The pre-alarm output is normally free floating and becomes high in case of imminent cell under voltage (default 3 1V/cell adjustable on the battery between 2 85V and 3 15V per cell). Maximum current: 1A (not short circuit protected) The minimum delay between pre-alarm and load disconnect is 30 seconds.

Charge disconnect output - The Charger output is normally high and becomes free floating in case of imminent cell over voltage or over temperature. Maximum current: 10mA. The Charger output is not suitable to power an inductive load such as a relay coil. The Charger output can be used to control: The remote on/off of a charger a Cyrix-Li-Charge relay a Cyrix-Li-ct Battery Combiner. (Note: in some cases an interface cable will be needed please see the manual.)

Remote on/off input - The remote on/off input controls the charging via the alternator. When off charging via the alternator is disabled while the BMS functionality will remain active allowing any loads and chargers to continue working regardless of the state of the remote input. When "system on/off switch" is enabled via VictronConnect the BMS functionality will also be disabled. It consists of two terminals: Remote L and Remote H. A remote on-off switch or relay contact can be connected between H and L. Alternatively terminal H can be switched to battery plus or terminal L can be switched to battery minus

Ignition proof - No relays but MOSFET switches and therefore no sparks.

Great sports/fitness watch
Color: Black/Yellow
I will start my review with an admission: I hate digital watches. I think 7-segment numbers look ugly, and I prefer the ability to see the 'distance' between times visually that you get with an analog face. But I needed the timer and lap counter for my job, and I have always wanted to do interval training to improve my speed and endurance while cycling. This watch had everything I needed and more. I was aware that Timex was a respected brand, and the T5E231 was the only watch in my price range with the ability to count 199 laps. I have to say, though, that after a week of use, I actually love this watch. Not only does it meet my needs functionally, but it actually brings me pleasure to wear it and operate it. The yellow trim around the inside of the bezel clearly identifies it as a sport watch, yet it seems to fit in well in formal settings. The interface is incredibly user-friendly and satisfying to operate. I never thought I would refer to a watch's "interface", but this watch actually has one. Pressing most of the buttons results in actual text being displayed on the screen telling you what the button did, or what will happen if you hold that button down just a little longer. In most modes there are even little labels that appear on the screen by the buttons telling you what they do in that mode. Figuring out how to use almost all of the functions only required five minutes of random experimentation. The only thing I had to consult the manual about was how to switch the chronograph into lap counter mode. I just wish there instructions explaining how to fold the manual back into a size that fits inside the watch stand. There are so many little touches that make it clear the designers at Timex really take pride in their work. Here are my favorites: -When turning night mode on, the Indiglo lingers for another few seconds after releasing the button. But when turning it off, the light extinguishes immediately! It should, since if you are turning night mode off, it's probably daytime and you don't need the Indiglo anymore. -Being able to scroll numbers backwards and forwards while setting times. On other watches it is so frustrating to 'miss' the number you want and have to press the button 60 more times. -Little icons appear on the home screen letting you know if the timer, chronograph, or alarm is running in the background. Most watches only have an icon for the alarm. -The speaker plays a different sound for the alarm and the timer, so you know which one is going off without looking at the screen. Also the Indiglo light flashes. -The Indiglo system is clearly a masterwork of engineering. It looks evenly lit and is very easy to read, yet it doesn't illuminate anything other than the display (unlike the backlight on a phone, for example). This must save a lot of battery power, since lighting up other objects around the watch is a waste of electricity. Besides, you have your phone for that! -In timer mode, you can see what time the timer was originally set for on another line below the countdown. -The AM and PM appear in the same place on the display; there is just one little segment that lights up to turn the P into an A. -Many of the buttons that perform an irreversible or potentially unwanted function (such as resetting the chrono or clearing workout data) require being held down for several seconds so you don't trigger them accidentally. -The watch tells you how much memory is free for storing workouts. There is only one problematic thing about this watch (and it may actually be a problematic thing about myself). In order to activate the FLIX system I am required to wrench my arm so hard I nearly dislocate it. It is painful, and takes way more effort than just pressing the Indiglo button. This doesn't bother me, because I didn't buy this watch with the intention to ever use FLIX, but it is somewhat frustrating that it is so hard to use. However, it is possible that my technique is flawed, and there is an easier movement that will activate it. But I don't really want to experiment; I like my arm in its current uninjured state. In all, I am very satisfied with my purchase. I love everything it does, and the only 'negative' probably says more about me than it does about the watch. Considering my abhorrence of digital watches, I am surprised that I like this one so much. I don't plan to wear it any other time than while at work or working out, but for those times it is not only tolerable, but actually enjoyable. I highly recommend this watch!

Decent watch for the price and very easy to read
Color: Black/Blue, Color: Black/Blue
I would consider this equal to the Timex Easy Reader except without Indiglo and less expensive. It is a nice size with quoted average water resistance. It has a press-down back and mine has a gunmetal color sort of sand blasted finish case. I don't know if it's coated or the actual metal color. The strap which came with it is of the NATO type and of decent quality. In the pic it is wearing the rubber strap from my Vaer watch which is a quick release rubber one. NATO straps are fine if you don't mind the double thickness of strap between the watch back and your skin. The spring pins aren't the typical ones which have the raised parts which allow you to use a removal tool. They are quite difficult to remove but I did it using a box cutter and by applying pressure I was able to eventually work them out and put normal ones on. The strap width is 20mm. I have a bunch of other straps which I can use with this watch. The full face lume is quite bright but I don't know how long it lasts just yet. If in a couple of years it needs a new battery, don't use a kitchen knife to snap off the back, use the proper tool which you can find on Amazon and follow the online tutorials on how to get it back on. All in all it was a good purchase.

Good watch
Color: Silver/Green
This actually a good watch for the price. It glows in the dark due to solar exposure during the day. The wrist band was a little long for my first.

No complaints, attractive, good work horse of a timepiece.
Color: Black/Green
Works great. I gave the luminous face a couple hours under a table lamp. When I went for my nightly half hour walk it glowed green the entire trip. Did not dim out like other watches with luminous hands/digits. So I know it glows for more than half an hour. My 2nd watch from this manufacturer. The other is an infantry watch OD green. Had it for 4 years daily use and still runs great. Changed the batt once. Could not see it in the dark at all. So, this new purchase for nights. I recommend it.
