Kawai Cat Repellent, Solar Power Ultrasonic Waterproof Pet Repeller, Battery Operated Pet Deterrent with Flashing Light for Cat, Dog, Animal (Black)

Coleman sont des produits ??? celui-ci charge deux batteries indépendamment de leurs chages respectives.

Easy install. Using it to split charge between my boat lift and boat battery. So far, it works well.

Works great for charging 2 batteries with a single solar panel. Had one on an RV and now a remote observatory

Works like a charm! Have it charging the starting battery and electric trolling motor battery in my boat. Once one or the other battery is topped off, it automatically sends the *extra* current to the remaining battery. Couldn't be happier. Great product.

I purchased this controller to upgrade our sailboat's solar-charged battery bank from one (starter) lead-acid battery to two (starter and "house" deep cycle type). The pre-programmed default settings met my needs for this application, sending 90% of the charging power to our #1 starter battery, 10% to the deep cycle battery until #1 is fully charged. Then the power is diverted to #2 until fully charged. Then there is trickle charge to both. It seems to be working as described. Two things I don't like: (1) The slotted screws that clamp the wires inserted by the installer are at the bottom of a very narrow aperture, such that I had to buy a special screwdriver with a narrow blade in order to tighten the connection. (2) The display is rudimentary. I knew this from the product description and image, and chose this product anyway to save money. I somewhat regret it because the Epever model it replaced (https://www.amazon.com/gp/product/B01BXRIRQC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) has a very informative LCD screen, and you don't need to memorize the secret code of blinking lights to tell how it is operating. All in all, I am satisfied that this will perform as we need for our unplugged boat, on a mooring, so that we will always be able to start the engine.
