About this product

Model:  Tracer-BP2544
Part Number:  BP2544

Lithium power packs from Tracer offer a light weight, powerful alternative to traditional batteries. This model is the 12v 8Ah Lithium Polymer option weighing only 600g!

Lighter. Smaller. Better.

Just ¼ of the weight of a traditional sealed lead acid battery, this 8Ah. 12V lithium polymer battery pack weighs just 600 grams and will easily fit in a coat pocket or clip to your belt. Gone are the days of carrying heavy lead-acid batteries. You won't believe the difference!

Flat Discharge - Brighter for longer

Lithium polymer technology gives a very flat discharge curve which means sustained power to the end of the cycle. If you are powering lights they will remain brighter for longer, giving you sustained performance.

Built in Fuel Gauge

With the built in Tracer fuel gauge you can check the power level remaining in the battery. A touch of the button shows how much energy remains and whether you need to recharge.

High Efficiency Smart Charger

The compact 1.6A Smart Charger (included) will charge your battery quickly and is available in either UK or European configuration. (Please specify European when ordering).

Universal Connections Available

Tracer battery packs can power any 12V application. As standard we provide connectors to supply Tracer lighting products and also a 12V cigar socket adapter. (Ideal for mobile phone car chargers or portable DVDs).


The battery pack is protected against over charge and discharge, there is also short circuit protection.

Certified Safe

All Tracer lithium batteries conform to the standard UN 38.3 transportation test. Our battery packs have been through a rigorous testing procedure by UN certified inspectors. You should NEVER handle a non-certified lithium battery pack.

It's not heavy.

I use it to power the cooling fan on my Dobsonian telescope mirror. It's light weight and small size means I can mount it on the mirror box. It's high capacity means I don't need to recharge it frequently. Perfect for me.

Just the job!

Small, lightweight; this is featherweight by comparison to the Sealed Lead Acid versions! I've not been able to run it down as most sessions have been 4-5hours. It powers my goto Celestron 5SE . Charging is easy - the unit cannot be overcharged, and there is a power level indicator on the unit.

Q1. Does this come with a lead to attach to my mount?

It comes with a cigarette lighter socket adaptor - most mounts come with a lead that will plug straight into this.

Q2. How can I power multiple devices?

To power multiple devices we recommend a 4-Way Cigarette Lighter Adaptor.
