Just took delivery of an Iota DLS-30 M Series(no internal IQ module) and the plug-in IQ Lifepo charge controller. I connected the charger up to a new out-of-the box SOK 100AH 12V Lipo4 battery which measured 13VDC. No load the charger measured 14.8 VDC. Connected to the battery the Iota charger went into bulk charging at a measured 29 amps @13.65VDC for approximately 15 minutes and than switched to a 9 amp @ 13.32VDC float charge. I thought this was a bit strange so I unplugged the charger and disconnected the battery and then connected and repowered the charger. Same result: Bulk charge for 15minutes (IQ module flashing) then float charge of 9 amps with IQ module LED lit solid. The charger is switching to float mode after 15 minutes instead of staying in bulk mode until the high trigger voltage of 14.6 volts is reached. I plan to call Iota customer support Monday morning. I purchased the Iota charger as the Aims adjustable 75amp charger appears to be on back order at suppliers. I purchased on Amazon so I should be able to return. Any assistance or suggestions much appreciated.
