In the past they charged fine no issues. Now, I can''t get them to charge or even put any power out. I''m using a Spektrum smart charger. The balance lead on both doesn''t seem to work. The charger asks if I want to charge without balance lead (even though it''s connected) so I click yes then it states battery abnormal condition.
