I've got a little problem here... I digimodded my UA-5 properly and it works fine when connected to the AC adapter or to RC battery packs... but I think my SLA might be fucked... it's been charging for a LONG time and the charge complete light hasn't come on... the UA-5 will power when connected to it, but the optical out light won't go on... Any ideas? I have the SureCharge Float Charger with 1A output from batterymart.com... any ideas? Thanks guys... you've been real helpful lately.
