The innovative PST-BP200
uses a leakproof sealed lead acid
battery to create a 15 pound portable
power source. Includes both AC and car
chargers. Battery pack with cigarette
lighter output. Often we get calls from photographers, astronomers, field researchers, CPAP patients , campers and plain ordinary people like us who need a convenient source of portable power to power DC equipment in the field. The BP23 2.3 AH 12V accupack was developed for this purpose, and now the BP-200 extends this to almost 10 times the stored energy, weighing less than 15 pounds (with other configurations that store and weigh less). The charging can be done from an AC outlet or a car, and the output is a female cigarette lighter socket output for easy use. This is a package consisting of a 7.5AH to 22 amp-hour, 12 volt sealed lead acid rechargeable battery, a 12V cigarette lighter socket output and both an AC charger and a DC car charger. |

It consists of a tough padded nylon-canvas fabric bag that contains the battery and wiring for charging and discharging. The sealed lead acid battery can be charged or discharged in any position and is completely non-spillable. The charger is in a pouch and can be left home if you don't want to carry it with you. For example, when the portable battery is used with your cell-phone car charger attached the BP-200 can run a typical cell phone for 150 times longer than the battery in the phone, or charge the phone 100-150 times.

Specifications
Portable battery life table:
*Based on cell phone batteries of 1400 to 2800 mAH, 85% charger efficiency. Note: Cycle life predictions are based on 70% depth of discharge at 25°C. The battery is considered "dead" when 60% of intitial recoverable capacity remains (in other words when a 20AH battery can only supply 12AH when fully charged it is considered to be at its end-of-life for the purposes of this specification). For 100% depth of discharge (to 10.5 volts) the cycle life will be about half of that in the chart. To achieve these cycle lives the battery must be kept at full charge when not in use. The included battery charger is design to accurately and safely charge and maintain the battery and may be left connected to the battery continuously if desired for standby purposes.
