This new graphite adjustable battery holder is from Xray for use on their T4 chassis and allows for adjustment to eliminate battery play on the chassis. The battery position can be moved forward, rearward, inboard or outboard depending on the battery size used, allowing the battery to be positioned ideally for chassis balance and tuning needs. If heavy electronics are used, the battery can be positioned more outboard to achieve proper balance (or inboard for lighter electronics). The battery can also be moved forward for increased stability or to the rear for additional steering.
