[NSRCA-discussion] 10s LiPo Charger Recommendation

Thu Oct 8 15:59:58 AKDT 2015

I find it interesting that Thunder Power would not recommend parallel charging,  when the TP pack I took apart for a friend recently was wired 5S 2P.

For some reason TP does not recommend parallel charging.  Probably because it is difficult to keep track of each cell and values are averaged.   Is this really an important factor?  At this point I just following instructions.  This factor could be important to decide what charger to buy.

Parallel charging 5 flight packs in one session while having a couple cold ones!

Hard to beat the iChargers. The CellPros taught me that a fuse between the pack & charger is a good investment! No issues with 3010b iChargers  (about

3000 charges over 5 years or so). They  will report cell IR / voltage and charge a 10S pack at 2C with a 24v supply without breaking a sweat. The newer 4010 can handle 2x10S and displays data from both packs simultaneously. They don't meet your criteria of charging through the balance leads, but haven't really found that to an issue as the balancing system works fine. Can't really comment on service, haven't needed any (that should jinx me).

Hi all, I m in need of some advice/suggestions for a new LiPo charger for 10s packs.

For the past several years I ve used CellPro-10S chargers with good results..

However recently one of my CellPro-10s' emitted the dreaded  magic smoke  when I connected a 10s pack for charging.  This also happened at the Nats 3 years ago, fortunately Mike M. from F3AU was there with inventory and I was able to purchase a replacement charger and press on.  However, after having a second one give up the ghost a few weeks ago (and after not many charge cycles - I don t fly very much), I m interested in exploring other options.

To try to add some focus to this here s my search constraints:

1.  It must be able to charge each cell individually through the balance connector, and give me a relative readout of each cell s condition compared to the other 9 cells.

2.  I m not interested in chargers that have separate balancers from the charger (e.g. like the TP1010C).

3.  Reliability and value are important, as is ease of use.

4.  Cost no more than a replacement CellPro 10XP (<$180), unless a single charger can charge two 10s packs simultaneously, then I d consider spending a bit more.

5.  Customer service matters, if I can buy it through F3A Unlimited, that would be a PLUS.

With this in mind does anyone have a suggestion for what chargers I should

consider?

I don t get out much these days so it s difficult to see what everyone s

using that works well.  So I really do appreciate everyone s help with this.

Thx, Jerry
