This is it. At $475, or whatever, easily $150 more than similar, it is quality. And you can mount it almost anywhere saving valuable protected space. Simple to install, virtually not setup and works as advertised. Smaller than the 50A Kisae and no fan. This is the 40A version but I'm reasonably sure the 50A is equally good. Review: REDARC BCDC1240 performs - Easy install and works great for both the solar and alternator charging. Love the product and would recommend to anyone thinking of buying. ## Features - Dual Input Charger for On-the-Go Power: This in-vehicle DC battery charger keeps your secondary battery fully charged while driving. Dual inputs let you charge from your vehicle alternator and solar panels at once for reliable off-grid energy - Solar Ready with MPPT Efficiency: Harness clean energy wherever you travel. Built-in Maximum Power Point Tracking (MPPT) optimizes solar output and Green Power Priority selects solar first, reducing alternator load and maximizing charging efficiency - Multi-Stage Charging for Any Battery: Portable and compatible with AGM, GEL, standard lead acid, calcium, and LiFePO4 lithium batteries.

You'd most likely want that functionality from a separate battery monitor anyway, though. As far as I understand, most chargers will only know when to float your battery. They won't know what percentage your battery is at between dead and full, or the calculated time to full discharge based on usage, or a handful of other useful stats/info. **Q: What is the maximum volts for the solar input?** A: Hi there, Thanks for your message and apologies for the late reply. The maximum open circuit voltage (VOC) that our chargers can accept is 32V. You are needing to use '12V nominal' type solar panels with our BCDC units. Best regards, REDARC **Q: On the lifepo4 set up,the redarc chart does not specify if that set up is for 1 or 2 lifepo4 batteries, does it mean is the same size wire regardless?** A: Hi there, Thanks for your question. Technically the BCDC can be used on either one, two or three batteries - we normally ensure that the amount of AH the unit is trying to charge isn't too large for it (eg around 200AH maximum). So yes the wire size chart is still applicable no matter how batteries you wire on the output side of the charger, just go by the length of the cable runs instead. We hope that's helpful! Best regards, REDARC **Q: Is this unit water tight? can it be mounted unter the travel trailer?** A: its water proof but you need to mount it: 1-As close as possible to the battery being charged (auxiliary battery) 2-Away from any direct engine heat. 3-For Caravan or camper, near or in the battery compartment is generally the best position. 4-Mount the BCDC to a metal surface if possible to ensure heat dissipation. So I guess the answer is no ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pricey, but worth it... *by K***R on October 15, 2022* I've installed 20 DC-to-DC converters. This is it.
