We have purchased 2 of your 100ah Batteries and have been very pleased with them, they are in our 2022 Geo Pro 15tb camper. My question is on longer boondocking trips with a lot of cloudy weather the batteries get low, can I use jumper cables from my 2019 4Runner to partially charge the batteries? The 4Runner has dual battieries, I would use my accessory battery which is a AGM battery charged by a Redarc DC to DC charger.
