I recently purchased a 2019 Kodiak 700 EPS (replacing my 1987 Moto4 250) and intend to use it for heavy noxious weed spraying, light snow plowing (Warn 3500-lb winch), dragging larger fallen timber off ranch trails, and general running around over pretty rough terrain, mostly at slow speeds and low engine rpms. Some work will be done in cold temps - even sub-zero. I fear that the stock battery and charging system won't handle the loads, especially when winching myself out of a mess with no engine power. I've considered fabricating a suitable battery box and wiring an automotive battery in parallel with the stock battery. While easily done, would doing so be advisable or could it damage or ruin the machine's electronics and/or charging system? Would stock fuses guard against over-currents from a higher amperage auxiliary battery?
