  • 7.2 V batteryholder for replacement

    posted by lasermanathome on 17:20:17 G9T 27/09/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Can be used in older 7.2 V rechargable electric tools and is small enouch to replace the NiCd or Ni MH 7.2v batterypack, the reason to buy them. They are small enough to builld them IN the batterypack but recharge is a bit more difficult or a balancer is needed. Two big advantages you will get, the batteries will remain recharged after even a year or more and the mAmps are about twice the original.

    Cons: For enough current, replace the wires of the 2X 18650 batteypack for 1mm^2 or better otherwise they will melt and use LiIoncells wich can draw at least 6A (often the protected cells will prohibit this, they can be removed but cells with high mAH can have pc's wich allow < 6A and will protect cells when they have to be recharged. Also the memory-effect of the old batterypacks are history. that is not a con;;;;;

    Other: Fron 4,8 to 9.6 V packs this solution will do fine, When 12-18 V packs are used you can take two of this batteryholders in serie but rewire them with thicker connectionwires. DO NOT TRIE TO RECHARGEV THE CELLS IN SERIE but remove them and charge them separately or use a balancer certainly when you use unprotected 18650 cells. IIt seems a lot of work but the Li Ion cells will surprise you in as well power as long lasting using one charge. Sometimes In use one protected cell wich has also the lowest mAH, this prohibits undercharging and destroyed cells. In my experience they will work better than the LiPo packs wich always demands a balancer and show a higher selve-discharge.

    Involvement Level: Expert (understands the inner workings)

    Pros: Good small size fits protected 18650 batteries without any problems. Love them and have ordered many of these type holders before very durable and long lasting. When full can provide up to 8.2V. Count 4.1Vx2 when fully loaded basic batteries.

    Cons: No problems to say for it is a rigid holder.

    Other: Cheap buy many good product to have to use in a lot of electric projects. Easy to remove batteries very happy for my purchase thanks very much.

  • 2 x 18650 Battery, very, very useful battery holder!!!

    posted by azmanovski on 16:00:59 G7T 02/07/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This battery holder is functioning as it supposed to. I ordered four pieces of it, so I can increase voltage connecting more batteries for my needs. The metal prongs are made from good quality metal,its a shiny metal and it looks like it will last long. I think that it doesn't rust easily. This battery holder has very good contacts. It fits 18650 batteries well and it maintain good contact even when the holder falls to the ground ( believe me I've tried that). Quality of the plastic is strong enough to hold the battery safely if they are not subjected to direct sunlight or other not suitable conditions for this holder.

    Cons: The red & black cables for the + & - terminals are very thin. You should be careful with the current in mA. The cable thickness and the way it was mounted to the + & - terminal should be improved further in every case!

    Other: Good product for the money.

  • Good battery holder case box

    posted by rpm4567 on 19:26:52 G6T 29/06/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a really good battery holder case box. I got it to hold two of my 18650 batteries for a DIY project to power a Raspberry Pi. Works just fine.

    Cons: I did try to put in some of my longer protected 18650 batteries (Panasonic NCR18650B) but they did not fit as they were too long. The TrustFire protected 18650 batteries fit just fine though.

    Other: Bottomline is that this does exactly what the description says for a good price.

  • item as expected

    posted by toninoooh on 21:21:38 G5T 22/05/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Item as expected,and as described in the ad,no much things can be said about it,it is just what expected,with the expected quality at a reasonable price

    Cons: No cons come to my mind. Connections and cables work,so no problems can be found,appart the quality of plastic,anyway this is not a thing to be shown,is for working,so,not really important or concerned about it

    Other: Best option I found,and a good buy. Would reccomend it,and would buy it again if needed it

    Pros: Pros: A great 18650 battery holder,holds two battery's at same time ,battery fits perfectly . What else to say it does what its suppose to do.Has 2 wires that come out of it so you can connect it where you want. Very simple product so there is not much to say about it......

    Cons: Cons: no have Switch is in the back, so if you fix this holder with glue or drill holes for screws, the switch will be against the wall. If the switch was at the end, fixing screw holew would be a nice addition.

    Other: Pros: A great 18650 battery holder,holds two battery's at same time ,battery fits perfectly

  • A good holder case for 18650 batteries

    posted by poteroa on 09:59:05 G2T 18/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very solid make, good plastic, wont crack easily. Other minus (-) spring was bent, but fixed easily. Ready drilled screw holes is a good plus.

    Cons: Leads are way too thin, but they are easily changed if any welding skills and equipment is available. If the battery is a "flat top" one, you might get some problems with the +-terminal sometimes.

    Other: I will buy more of these when needed, good price/quality ratio.

    posted by ilyakamb on 09:45:50 G2T 17/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I bought this cage because I need two batteries connected in series 18650, ie utilization voltage 8.2 Volts. It is used in the grips of electronic cigarettes that are adapted to two batteries. Design is more than enough and the battery is easily inserted into the cage and take out, which is important for charging. The big advantage is the very small dimensions of exactly replicating size batteries 18650

    Cons: The spring of negative pole is not strong enough to push the battery against the wall of the shell and achieve a balance contact of the positive pole. Electric cables are really thin. One of the welded joints between rivet and wire broke during assembling.

    Other: Overall, excellent quality for the price. Fits both protected and unprotected 18650 batteries.
