This is more of a user experience than a
meaning I will not go into a huge amount of
technical detail and performance tests etc.
This is about
my latest experience with these Genesis
batteries from Banana Hobby ... and
that experiance has not been so great. Be
it noted that I've used theses batteries
before and I still have some 3300 mAh 55c's
that are still going strong after over 18 months
These current batch of batteries, after only about 3-4 cycles,
slight puffing after a flight (DJI F550 Hexa)
even though I am only pulling 71 amps at max
throttle (battery rated at 275 amps
continuous/550 burst). The 'copter is my
photo/video rig and it's not like I have
been hot rodding it around.... actually the
only time it has seen full throttle is on
the amp draw test. Even at take off I'm
about 3/4 throttle.
I've meticulously charged them, never
exceeding even 1.5 the C rating for a charge
(the max my charger does is 2.5 amps anyway)
and all the cells are balanced to within .02
per cell.... and most are .01 per cell.
At about the same time I also got a small
3cell 40C 1000mAh battery and after only two
used it also puffed. This was only used to
power my GoPro camera gimbal. It looks like
the current quality of these Genesis packs
are not what they were a year ago...
after a couple more cycles they are all
definitley puffed. No more airtime for these
2/6/2014 - I just received my
replacement batteries (Thank you Banana
Hobby) and I will see how the new
replacements work out, please stay tuned.
- Again after only 6-7 cycles thes batteries
are puffing just like they did before. I am
currently awaiting a response from Banana
Hobby (my second request). At this point I
would definitely not recommend these
batteries and would stay clear until this
problem has been resolved.
- After over 2 weeks waiting for a response
I finally posted up a complaint on the RC
Groups discussion board (Vendor section,
Banana Hobby). I got a response within 24
hours. After verifying I was not abusing
these batteries they agreed something was
amiss with these batteries... two days later
I received a full refund.
Stay clear of these batteries until this
issue is resolved!
