Need Extra Power for Your Dynacraft Realtree UTV. Try These 10 Simple Upgrades

Check the Condition of Your Existing 24v Battery

As any avid off-roader knows, having enough power is crucial for getting the most out of your UTV. And when it comes to power, it all starts with your battery. The factory-installed batteries on most recreational utility task vehicles like the popular Dynacraft Realtree are decent, but rarely robust enough for hardcore use or heavy modifications.

So if your Realtree UTV seems underpowered, sluggish, or unable to hold a charge, it’s probably time to upgrade that 24v battery. But before rushing out and buying a shiny new lithium upgrade, it’s worth checking the health of your existing lead-acid battery first. Here’s a quick DIY guide for testing battery voltage and condition on your Dynacraft:

  • Make sure the battery is fully charged, either by running the engine for at least 30 mins or using a trickle charger overnight.
  • With the engine off, use a multimeter to test the open circuit voltage. It should read at least 12.6V (25.2V for the full 24v system). Much less could indicate a bad cell.
  • Check the voltage again with headlights, accessories on to simulate a load. A healthy battery should stay above 12V per 12v battery under load.
  • Inspect battery physically for any cracks, leaks, swollen caps which are signs it needs replacement.
  • Use a hydrometer to test the charge level of individual cells. All should be at or above 75% state of charge.
  • Consider having your battery load tested at an auto parts shop to be sure it still has adequate CCA.

If your stock battery checks out fine, then other upgrades like a new alternator or wiring improvements may give you the added oomph you’re looking for. But if testing reveals your current batteries are on their last legs, then it’s time to swap in an upgraded model.

High-Capacity and Lithium Batteries for More Runtime

The simplest upgrade is to replace the existing flooded lead-acid batteries with higher capacity AGM or gel models, such as a 24v 7Ah battery. Going with the maximum amp hours your UTV can handle will provide more runtime before needing a recharge.

For even greater weight savings and 3-4x the lifespan, lithium batteries are ideal. High performance models from EarthX can deliver huge cranking power in compact sizes. Though more expensive upfront, their extended service life pays off in the long run.

Just be sure to select a true deep cycle lithium battery, not a starter battery which isn’t made for repeated deep discharges. And use a lithium-compatible charger to get the most longevity.

Alternator, Wiring, and Voltage Regulator Upgrades

To keep those upgraded 24v batteries charged up, consider upgrading your Dynacraft’s stock alternator and wiring. The small factory alternators usually only put out around 40-60 amps, which may not be enough for high-drain accessories.

Bolting on a high-output 100A+ aftermarket alternator can significantly speed up recharging. Just be sure your voltage regulator can handle the extra output without overcooking your new alternator. An adjustable regulator like the Painless 30102 allows fine tuning voltage to 14.7v for optimal charging.

Upgrading the gauge of your wiring and terminals can also help maximize power flow from the alternator to the batteries. Old corroded wires cause resistance and voltage drops. Replacing with 4AWG welding cable and copper lugs will improve charging efficiency.

Dual Batteries, LEDs, and Other Tips

For the ultimate in electrical capacity, consider adding a second auxiliary battery wired in parallel with the starter battery. This doubles your amp hours for double the run time of high power electronics and accessories. Just be sure both batteries are of the same voltage and chemistry.

Replacing old fashioned incandescent bulbs with LED headlights, utility lights, and interior lighting can greatly reduce power draw. LEDs consume far less wattage while outperforming old filament bulbs.

And don’t forget regular battery maintenance for maximum performance and longevity. Keep connections clean, make sure batteries are properly mounted to avoid vibration damage, and try not to let them sit in a fully discharged state whenever possible.

With these upgrades and proper care, your Dynacraft Realtree will have the electrical brute force to handle any UTV adventure while keeping you powered up longer. Just take it slow and easy on the throttle until you get used to the instantaneous torque of that new lithium battery!

Consider Upgrading to a High-Capacity 24v Battery

Once you’ve tested your stock batteries and determined it’s time for an upgrade, the next step is choosing the right replacement. While you can go with another standard flooded lead-acid model, opting for a high-capacity AGM or gel battery can provide some nice benefits for your UTV.

Compared to old-school wet cell batteries, absorbed glass mat (AGM) batteries offer superior vibration resistance, faster recharging, and reduced maintenance needs. The electrolyte is suspended in fine fiberglass for steady performance even on rough trails. And with no liquid to leak or spill, you can mount them in any orientation.

Popular AGM models like the Odyssey PC2400T can deliver up to 70% more starting power versus standard batteries in the same footprint. Their extreme cranking current provides instant power to spin your engine over, even after sitting idle for months during the off-season.

Gel cell batteries work similarly, substituting the fiberglass separator for a silica-based gel. They tolerate even deeper cycling than AGMs. Either battery type can prolong the time between charges, meaning you spend less time plugged into the wall and more time off-roading.

The Lightweight Lithium Advantage
