Combo Special: Tenergy TB6-B Balance Charger for NiMH/NiCD/Li-PO/Li-Fe Battery Packs + Power Supply

This charger is great cause you can do a lot with it from quick charging, too balance charging it’s a great little unit for the price. It shows you how many volts per cell you have and how much is left to charge so you can keep track of the charging process better and it beeps really loudly when fully charged so you’ll never forget to unplug it when it’s done. The only problem I have is it’s not user friendly if you haven’t used a charger like this before. The instructions it comes with are really bad they can be hard to understand so I would recommend looking up the video instructions instead it’s a lot less complicated and they’re easy to follow along with. What took me an hour trying to understand through the paper instructions was broken down in a 5 minute video. Once you save the charge settings it gets even easier cause all you have to do is load up your settings and press start or you can use it as a baseline if you have batteries that are pretty similar but may have different capacities or voltages. Overall a great charger for the price but can be intimidating for first time users with the complexity of the paper instructions thankfully there’s a few videos out there so I’d suggest looking those up if your still confused about this charger after reading the instructions.

Intuitive to use and the balancing feature does a good job safely charging the batteries. It supports a wide range of battery types, but i have only used it with the lipo feature. The discharge feature doesnt heat up the charger too much and the completion beep is lound. The safety check is amazing, once the charing leads were reversed and it was able to detect the issue before charing the charge cycle. The only thing i dont like too much is that the wire provided with the balance charging port is a little short and hard to put my lipo batteries in the safety bag when charging.

Works great. Had to watch online videos to figure how to program and set up. Instructions could be better. No problem with product and charging. Recommended.

It does exactly what it advertises. I've charged probably two dozen batteries on it so far with no issues, ranging from small 1s 500 mAh batteries to large 6s 5500 mAh batteries; it's done the job with each of them. Comes with a balance board included and a charging harness that will cover pretty much everything, as well as 2 bare leads to solder whatever connector you want. Only thing it doesn't cover out of the box is XT90, EC5, and the JST-PH 3 pin that's used with batteries like the E-Flite 2s 280mAh or other similar batteries commonly used in micro/UMX. I threw an XT-90 on it myself and just use an XT90 to EC5 adapter for anything with an EC5 plug. You will need to buy a separate harness like Part# EFLA700UM or something similar to charge the E-Flite UMX batteries. Don't try to just solder a JST 3 pin on the battery and charge it because you need to balance anything with more than 1 cell. The unit doesn't come with a fan and is just heat-sinked to the aluminum case. I like it because there is no noise, and I've not had any issues with overheating, even when charging a 6s for ~2 hours, although I'm not a power user so maybe on some really hot summer day after charging several batteries back to back it may start to warm up. Obviously you can spend 2-4x as much on something like a large Venom charger, but for most people who aren't charging tons of batteries every day this charger should be more than enough to suit your needs and it won't break the bank doing it.I've seen a review or two talking about this thing being junk and batteries exploding, but there is never any information other than "this is crap, it's dangerous, it could have burnt my house down." I don't know the specifics of those types of accidents, and obviously equipment can be faulty, but more times than not it is user error and not equipment malfunction that causes an accident. I shouldn't have to say this but these types of batteries aren't toys and require the respect they deserve when dealing with them. For example, if you were charging a 2500mAh 3s battery, were in a hurry or didn't pay attention to your settings and accidentally selected 4s and charged your 3s at 14.8 volts, or you didn't use the balance board, or you used the "Charge" option or "fast charge" instead of the "Balance" option, or charged your battery at a rate greater than 1c, or you didn't check the battery and charged a damaged or "puffy" LiPo, you're inviting trouble and you could very well be looking at an exploding battery. Equipment can be faulty, and people can make mistakes. So never leave your charging batteries unattended and always be mindful of what you are doing. When charging powerful batteries like what this charger is meant for, always use a fireproof/explosion proof charging bag, and never leave your charging batteries unattended. If you are new to the hobby of RC, have never used lithium batteries, or are unsure of how to handle powerful batteries, read the manual, watch some videos, educate yourself on the basics. There's no need to be scared of them, just respect the power they have and you won't have issues, or you'll be prepared for one if it happens.

It does it's job properly. It shows cell voltages while charging. It's not crazy fast, but it works great so far. It is easy to use and looks pretty nice. I think the limit for charging is 1000mah. I am fine with that, as it isn't rough on the batteries and it has balanced every battery well.Maybe a little pricey, but it seems worth it as long as it will last a few years.
