Marko Posted April 28, 2008 Share Posted April 28, 2008 hi all Ive been to my local hobby stores to buy yet more stuff ! and i just happened to mention that my lipo batt i bought from them an impulse 3s showed a cell low after one charge and flight i asked about a balancer and was told "Ive never balanced any of my lipos and they have had loads of charges" as i think he might get a good staff discount on batts i bought one anyway , ther seams to be a lot of conflicting views from stores to club members as to how often lipos need balancing could you please advice cheers .....................mark Quote Link to comment Share on other sites More sharing options...

Tim Mackey Posted April 28, 2008 Share Posted April 28, 2008 Eric is correct in that it is" best practice " to balance each charge. However, there are some packs that I own from years ago that never had balance leads fitted and they are still going pretty strong ( Kokam 2000 )I also have a few 2s packs in IC models and Slopers where the discharge rate is so low ( radio only ) I confess to not bothering to balance more tghan about every 5 or 6 charges.

Erfolg Posted April 30, 2008 Share Posted April 30, 2008 Always balance, better safe than sorry.After fling there always seems to be an imbalance with my Lipos (7 batteries)Erfolg Quote Link to comment Share on other sites More sharing options...

Michael Lank Posted May 2, 2008 Share Posted May 2, 2008 I use an inline charger, that is plugged in between the charger and the battery. This makes it very easy to balance the battery with every charge. Quote Link to comment Share on other sites More sharing options...
Flash1 Posted May 2, 2008 Share Posted May 2, 2008 Buy a charger/balancer.You dont even have to think about balancingI bought mine from BRC Hobbies Quote Link to comment Share on other sites More sharing options...
Mike Johnson Posted May 2, 2008 Share Posted May 2, 2008 Buy the Tenergy charger it is in fact four chargers built into the same case and microprosessor controlled to ballance each cell as they charge individually, as far as I can make out it is the only ballance charger available, the rest seem to be chargers with ballancers attached, you can tell them by the fact they charge through the main power lead from the battery and the ballance lead attached to ballance the unit, the Tenergy only has the ballance lead attached and charges each cell individually whilst monotoring the chage rate and voltage, its very clever the way it reduces the charge rate on one cell to allow the others to catch up or visa versa. Shame its only available for up too four cells, they have a bigger one on the way, but not available yet. Mike Quote Link to comment Share on other sites More sharing options...
Brian Dickenson Posted May 2, 2008 Share Posted May 2, 2008 I always use a balance charger. Up to now have not had any problems.A question not related to flying. Why do some contributors not run the spell check? Quote Link to comment Share on other sites More sharing options...

Anyone else? also does anyone know of one that does more than four cells, preferably 10 cells at 5 amps, this would have to be a 300watt charger the only ones available are below 200 watts at this amperage and voltage and are not true ballance chargers, anyone know any different?

Edmund Comber Posted May 2, 2008 Share Posted May 2, 2008 I balance every charge. Bantam eStation BC8 with built in balancer. Most such chargers do not charge via balancing leads - they only discharge to achieve balance and the balance leads cannot carry sufficient current for bigger (most) batteries and the charge is via the main + - leads which are beefy. Charger warns in big letters (as do others) to connect balancer lead AND main charge output leads.Thinking of adding the Hyperion EOS 0610 6s Dual Charger with 2 Built in Balancers or the new Bantam BC610 Quote Link to comment Share on other sites More sharing options...
Eric Smyth Posted May 3, 2008 Share Posted May 3, 2008 Has anyone had a crash that they can definitely attribute to unbalanced cells? I wonder!Personally I balance my cells when a check shows a difference of more than 0.03v.No special reason for this it just seemed reasonable to me at the time!

Mike Johnson Posted May 3, 2008 Share Posted May 3, 2008 I have the Bantam 902 with the interlink to ballance my 12S packs, but as the BC8 this is not a true ballance charger, as Edmond says it just discharges as it is charging to ballance the cells, with a ballance charger which charges through the ballance leads you are only charging one cell with the smaller cable, admittedly the interface cable between two cells is taking twice the charge of the single cable on the outside cell, but in any case the charge input is divided by the number of cells in the pack, so a 3S pack charging at 10amps is only taking 3.3amps per cable to the outside cells and a possible maximum of 6.6amps to the internal - + connection, the Tenergy ballance charger is only rated for 6amp charging so the current taken by the ballance lead is even less, I have not seen a ballance lead yet that would not be capable of taking that load.

Erfolg Posted May 3, 2008 Share Posted May 3, 2008 EricI have practiced balancing my lipos for the last few days now. At first it was not easy due to the radius-ed ends to the battery, although it is easy if laid on their side (no need to balance). I have found that after a prolonged session of flinging, that the packs can get quite flat ends, which makes balancing on end much easier.I will shortly be going to Aberdeen to visit my daughter via M6 etc., (running the tax raising speed trap gauntlet of varying speeds, there is one section that is 50mph for about 1/4 mile, with two cameras, then back to 70). I will practice my Highland fling there. Although it is technically not the Highlands, except for deliveries, when it is.I no ow our fiend feels abart pour spellin, as uffers is to lasy to use spell checker. As I dont need need it, nar worry.Erfolg Quote Link to comment Share on other sites More sharing options...

Matt Hackers Posted May 3, 2008 Share Posted May 3, 2008 I have a CELLPRO charger that automatically balances and charges up to 4 cells and in some cases it can restore over discharged cells. Quote Link to comment Share on other sites More sharing options...
