The iTECHBC40 is a smart multi-stage battery charger that uses the latest switch-mode battery charging technology. The iTECHBC40 will charge lead-acid batteries and LiFePO4 batteries the most effective way.

The multi-stage charging algorithm delivers a fast, efficient and consistent charge with no voltage drop. Using charge algorithms that are tailor-made for each battery type, the iTECHBC40 not only charges the battery but looks after it. The iTECHBC40 will prolong the longevity of the battery cells and prevents premature battery failure. 

The iTECHBC40 has an innovative boost-charge feature; this helps activate a battery with low voltage. The boost-charge function will "wake up" a weak or flat battery to a suitable recharging level. 

The iTECHBC40 allows you to set for different battery types: SLA/GEL/AGM/Flooded/Calcium lead-acid batteries and LiFePO4 batteries. The iTECHBC40 can be used as a constant power supply to run accessories that require a stable and clean DC voltage. 

The input and output of the charger are entirely isolated, with overcharge protection. The iTECHBC40 has a fan which is thermally cooled. It will switch on and off automatically to control the internal temperature of the charger.

Important note: The ITECHBC40 has two positive terminals and this is to charge two battery banks of the same type simultaneously. If one battery bank is used then both of the positive terminals must be connected to the single battery bank.
