Custom Vtwin Facts & Tips!

The custom Vtwin motorcycle requires 2 ½ times more starting power than the stock Harley-Davidson ® engines. These bikes have the same stock 32 amp charging system and often come with the same size battery. Many owners of the Vtwin bikes have noticed soon after purchase that the bike has no or reduced starting power and believe the Harley battery has prematurely failed. To their dismay, when the battery is sent in for testing it is determined that the battery has no factory defects and was simply at a low charge level!

East Penn Manufacturing was the first motorcyle battery manufacturer to try and solve this frustrating issue! Using the Deka Magna Power brand, they created the ETX series battery for engines that require more starting power. Magna Power's high performance AGM batteries were one of the first brands to rollout this technology. Not only did they increase the available starting power, East Penn engineered the battery design to have flush mounting terminals—that’s right no more annoying spacers! These are great relatively inexpensive options, but they still leave some custom builds starving for power.

MotoBatt Hybrid: The Harley Battery Power Solution You Have Been Looking For

The MotoBatt Hybrid is designed specifically to address the known industry challenges with lithium and lead-acid only powersport batteries. The long stroke larger twin cylinder motorcycles from Harley Davidson, Ducati and BMW, for example, have high compression engines that are extremely tough on the battery. MotoBatt Hybrid combines the best aspects of lithium with the best aspects of sealed AGM allowing the battery to handle the huge inrush currents required to spin the larger starter motors and turn the crankshaft. No other lithium only or AGM only battery on the market comes even close to Hybrids power and steadfast performance!

To help keep your new Vtwin or Sealed battery fresh and in pristine working condition we recommend you use a three stage automatic smart battery charger. The MotoBatt MBRC35 selectable 12V / 6V 3.5A lead-acid / lithium smart charger comes with alligator and ring quick disconnect leads for easy plug-n-play operation.
