Due to the Constant Resistance rating and varying Voltage nature these capacity testers are ok for that your doing. You getting a fair reading at the end of the test. NOT Perfect but fair. As the Cell voltage goes down the Current goes down. These testers provide a in the ball park capacity reading. It would have been better if they provided a Resistor that centered on the Batteries NOMINAL voltage of 3.7v. That way the Upper and Lower Limits measured would be more equal. A 3.0 Ohm resistor would have balanced out much better on top and bottom of cell charge or SOC. Yes I will replace the resistor with a 3.0 Ohm type. The Current being used would stay much more constant.

As Advertised. Super Good Deal. Packaging could have been better for sure. Piston should have been at least rolled in some paper. Arrived a bit Scratched and Dinged. All Repairable but a sheet of paper would have prevented it. Will be buying a few more. PAPER PLEASE ?

I intend to use a few 18650 batteries to drive this outputting 5V required to operated the BIKIGHT 3000LM Waterproof T6 USB Power LED Bicycle Front Light... on my motorized bike. The T6 light requires 2A @ 5vdc. The LM2587S is limited to 5A output but will do this job nicely. Thank You !

Seems to do what I need done using the Red and Green settings. Purple BLOWS holes in 18650 cells. LOL Bet folks would be willing to pay a extra dollar for documented instructions ? I located the Cap on the underside.

Super good price on this hardware. Going into a CPU Cooling System. Originally receive this order in error. Only received the short Kit with one Heat Sink , one fan and water jacket . On Contacting Customer Service BangGood Corrected that issue by re-sending out a Whole New Full kit. as described. Thank You for the Rapid Customer Service Response and Services on this BangGood.

This kit is a super value for the price. My kit arrived missing one fan, one Heat Sink. CS Contacted. I'm quite sure CS will rectify the situation. BangGood is good with resolving issues.

Excellent for Small Solar Projects. Continuous Out Put Voltage, CC , CV with Battery Low Voltage Protection. Wish I could find a 20A or 30A unit performing the same tasks. These units perform some what as a Poor Mans MPPT. You do realize a bit of Current Gain via over Voltage Buck Down to Working Voltage ( Set Out Put Voltage ) . When Source Voltage is less then Working Voltage ( Set Out Put Voltage ) your able to obtain limited Charging current . Better then NOTHING, eaaaa? Again Looking for a 20-30A versions of same ?

200mA is not a boat load of power. Connected to our well head we are able to maintain a charged battery for a PIR light on the well. Just.

Q: How do you focus the thing? I can't figure it out.

gefragt von James auf 2021-01-09 02:09:46

Taner Please note. When inserting the battery, place the positive terminal of the battery toward the tail and the negative terminal toward the head

As usual BangGood provides. Ordered Three of these converters. Working building E-Bike batteries I needed a way to charge 18650 batteries prior to testing. These will do the job. After using them for a while I realized I needed to charge More Batteries faster then I can using this Item. Now ordering two of the 600W Boost Converters to allow me to charge more then a few 18650's at one time. It would have been nice if BangGood would have provided a basic informational document with these things. Took me a little while to figure out what all I could do with them. After this Battery Project is Complete I will employ them as Super Versatile Battery Chargers. If it's a battery and chargeable these can do it.

Listing describes a 35A 35A charging current. Units I receive (TWO) are 30A 15A charging. These units will work for the purpose I had intended but are NOT the units I order. What's with that BangGood ? It would had been nice if you contacted me prior to shipping ?

This CDI is much better then the one you receive with the Magneto / CDI pair available. Unlike the one that comes with the Magneto you can twist out the HV Lead and replace it if needed. Thank You BangGood.

Works. Works better if you replace the 12 AWG wire to the Probes. Works better then better if you replace the 10 AWG leads from Battery to the Unit. Use at least 8 AWG . Don't expect much from the Probes. Well worth the price. Have a second order in shipping. Yes I like this.
