I purchased a pair of 7.4v sticks for my buffer tube from an online retailer. When I received them and plugged them in my charger declared them to be low voltage and wouldn't charge them. I spoke to the retailer and her recommended charging them at 0.1A on NiMH. I very carefully did this and they now have sufficient voltage to charge correctly. However they don't seem to hold a charge. I charged both to 8.4v and checked them a few hours later and they dropped to 8.15v.
Is this normal? I am planning to exchange them regardless (unless I am convinced otherwise) but I would like to know what voltage drop I should expect as I though Lipo's held there charge for a long duration.
