Megawatt 40-amp
Sixty-five bucks. Set to 14.8 volts. Use an ammeter and when charge rate drops to 12 amps shut off generator. Before storage let charge until all cells are bubbling vigorously. Maintain discoonected from all loads fed by a 20-watt solar panel regulated to 13.4 volts. Do not leave batteries unattended longer than 90-days.
BUT BUT IT WILL BURN MY BATTERIES UP!!
Started talking to a guy about our axle flips and we ended up on batteries. He said hes gone through 3 in the last 3 or 4 years. I got out my hydrometer and it was around 1.125. I showed him my battery set up and mega watt and told him that we could put it on his battery for a while. He said he was afraid of burning his battery up and didn't want to try anything like that. Ahhh ok.
As we did all this another guy next to him came over and starting asking questions. We checked his and the voltage was 12.6 and the sg was just above 1.125. They both complained about their refrigerators cutting out at night. Geez what voltage does that happen at? 9.5 or something?
He has a wfco and a 160 watt solar panel behind the truck cab pointed away from the sun. It's wired into the controller in the bedroom and the controller then goes out to the pinbox area to tap into the hot wire. Then of course it runs all the way back to the power center where it then travels back to the battery. His walmart group 27 was new in November. He returned it and they gave him a new one. He told me it's working great now, it was just the battery. WOOOOSH, talk about over the head. Wasted every minute of my time. Then that evening the wife points to a big DP and says I wonder why they walk around in there with flashlights and dont just turn on a light. I got up and went in and turned on every light in my rig and opened the blinds a little then went back out to the campfire. Life is good when you have the power.
