just wondering If anyone "has" tested for IR of 5200 4s packs recently ?and found irregular high readings !
Ive tested with a Hyperion 720 duo ,and a thunder power TP820cd,and both show high ir and poor cell matching ..
Surprisingly however, they dont seem to be far out of ball cell voltage ,at end of a 12.5min run!
I've cycled both packs 5 times before using in the buggy ,and IR improved a little in the good pack (now at @ 12mh),and pack 2 now 14mh.but individual cell ir is not improved ! ie , pack1 (c1 to c4)is 3,2,3,2.mh pack2 is 3,1,5,3.mh.
As i mentioned earlier,both myself,and others localy,have been using these vant 5200 packs all year ,and i havent heard of a legit complaint about them ,and ive been singing theyr'e praises ,not only for great run time punch and all,but mainly because theyr'e so light weight 485gms !,in a MBX7 they ballance the the car perfectly ,compared to simmillar capacity batts .

I'me waiting to hear from the AU supplier as the outcome of my complaint/enquiry,will post any results
