I have a super brain 989 that I use for Lipo Charging that has worked well for me, for balancing I use a blinky balancer. Well, I have finally got into bigger lipos and now need to start charging 6s packs. The 6s packs that I got have two balance leads coming off them. When I read the voltage off each of these leads it looks like they have put 3 packs on one lead and three packs on the other lead with a yellow wire thrown into the mix on one of them. It's a Thunder Power 2850 6s 45C battery.... (If that helps)

My question is.... is there a separate balancer that I can get to help balance these packs?? Or do I need a new charger??

Thanks for the help!

I sold another one to Terrafirma...... wife wants to know where the money's at!!!!

You could buy a balancer that would work. Most of the separate balancers including the TP models will work as a stand alone balancer. That said you would very likely be better off just buying a new charger. That would give you a smaller, more modern unit with a balancer built in. It would also give you the opportunity to step up in output capability. The 989 is not weak but many of the newer chargers out there offer much more power. This will become a problem if you would like to charge larger packs, charge faster or charge multiple packs at once.

Here are the TP balancers. Remember that you will need a 210V for 6s balancing.

Now that balancer is nice but it costs $100. For only $20 more you could have a new and more powerful charger.

Just a thought.

I hear ya..... I just got my 989 a year ago, and I have about 4 other chargers just sitting around that I have a had to purchase over the years because of new battery technology..... the thought of purchasing a new charger again makes my skin crawl.... LOL

Thanks for the info.... I had no idea that TP made a stand alone ballancer.

Would something like this work??????

Also... does the battery get charged though the balance leads? I'm only familiar with the way you balance and charge from a blinky.

I also found this one..... which between the two would you suggest?

There are really 2 ways to use a balancer, passively like your blinky or actively like built-in balancers. Neither way charges through the balance leads. The TP balancer and others work both ways, actively if you have the right charger and interfaces or passively they work just like your blinky. I see two drawbacks for using balancers in "passive" mode and both stem from the fact that there is no connection between the balancer and charger. First there is no built in way to check the number of cells. You could set the charger to 4s, plug in a 3s pack, connect the 3s pack to the balancer and there is no way to stop the charger from overcharging the pack. The balancer will do its best to bleed off the extra voltage but it will loose and you could have a fire on your hands. Secondly you don't get to monitor the pack stats from your charger. You can't look at the cells to see how they are doing. Once you get an integrated balancer the charger gets safer, more informative and more useful. In short it is just the way to go in my book.

As for chargers aging, almost all of the newer models have upgradable firmware and that should future proof them some, allowing for new things to be added as they come up be it features or new battery types. There there is the cost of many of the new chargers. Gone is the day when a powerful and feature rich costs $300+. Now you can get everything you need for less that $200 and maybe even less than $125.

Here's the deal.... I'm a nitro guy. Pure and through.... I just happen to come up on 500 electric that I'm gonna give a shot for cheap. If I love electric...I'll get a new charger after some time. If not, I would rather start with a balancer.... so....

That one will foot the bill right??
