A pair (the pic show only one) of Keeppower protected Panasonic 3400mAh for $21,82 with coupon SWIATELKAWB (expires end of Dec.) only $19,20 - I know, that unbranded protected Panasonics are cheaper, but the PCB of Keeppower is great PCB trip current 11,5A (HKJ review and he wrote "very good battery").
