CREATE THE ULTIMATE POWER SYSTEM: Pair the PowerTop with the ultra lightweight and durable 180w BainTuff Foldable Solar Blanket, plug the blanket directly into the PowerTop and it will supply up to 10A of reliable power to keep the PowerTop’s 100Ah gel battery charged. While on the move, a DC-DC charging system like the CTEK D250SA will recharge, maintain, and extend the life of your auxiliary battery via your alternator, or utilise the solar input while set up at camp, giving you the freedom to live the good times for longer.  


Always charge before use. Correct charging will ensure you get the best life out of your 100ah GEL Battery. We don’t recommend deeply discharging the PowerTop, as this will reduce the life of the battery. It is recommended to use a charging source to keep the battery topped up – the perfect off-grid option is to utilize either method of solar or alternator charging.

Battery charge guide

Never store a battery in a discharged state. Sulphation can occur when the battery is left around for long periods in an unused state causing it to loose capacity. Letting the battery voltage fall lower than 50% or 12.4 should also be avoided.

An unused fully charged battery should sit on a reading of 12.8 volts for a couple of weeks before needing any further recharge. Store in a dry cool place, and always fully charge your PowerTop via the AC internal charger before each use.

It’s important to remember that although your battery may be rated at 100amphour, exceeding a depth-of-discharge beyond 50% won’t do it any good. For a 100 amp-hour battery, you should base your amp draw calculations off a 50 amp-hour of useable capacity. 50 amp-hours of usable capacity would mean that you could discharge 1 amp of current for 50 hours, or 10 amps for 5 hours, 6 amps for 8.3 hours – all depending on the amp draw of your accessories.
