Parallel Connecting EXP PRO Batteries
Did you know that you can parallel connect EXP PRO batteries together to increase your capacity?
EXP PRO batteries can be parallel connected by using the provided DC charge cord that comes with each battery. Up to two EXP PRO batteries can be safely connected at one time.
The process is fairly simple. By using the provided DC charge cord plug the 5mm barrel shaped end into the charge port on the battery you intend to use for powering your device. Then plug the DC end (this looks like a cigarette style plug) into the main power port marked 12V/15A on the secondary battery. This will add more available capacity, and will allow a seamless draw of power from both batteries at one time.
Why would someone want to parallel connect two batteries together?
There are several reasons for parallel connecting batteries together. Here are a couple popular reasons we've found:
1. You're going on an airplane and need back up power where one battery won't be enough power for your adventure. Airlines have their own rules for safety. Luckily there are ways to work within these rules while still being able to bring enough power on trips. Up to two of the EXP48PRO batteries can be brought with you in your carry-on luggage. The FAA regulations state the limit is 160 watt hours (Wh), and the EXP48PRO only contains 153.6 Wh per battery. Unfortunately, the EXP96PRO battery currently exceeds this range and is not TSA compliant.

Kevin,
The USB-C or the 5.5×2.1 barrel port can be used to charge the battery with a solar panel. The battery can accept up to 20v @ 2.25 Amps through the USB-C port or 12-24v @ 2 Amps through the 5.5×2.1 barrel port. In addition, it’s possible to use dual charging through both of these ports simultaneously to charge the battery. Dual charging is capable of fully charging the battery in 1/3 the time compared to using a single charging method alone.
If a solar panel is to charge my EXP48Pro or my EXP96Pro, what input ports can I use? Can I use the Type C input/output port? Can I use the 5.5×2.1 barrel port? Can I use the 12V cigar ligheer DC port? And what is the fastest/greatest amount of power the battery can accept from a solar panel? I am looking at a variety of panels for canoe tripping where size of panel, output and versatility of panel is important, not to mention the cost of the panel. Your help with this would be much appreciated.
Kevin,
When using the parallel battery hook-up, the total power (or nights of sleep) would be equal to the two batteries added together.
When using the parallel battery hook-up, does the extended power equal the power of each battery added linearly (e.g. – 2 nights worth from an EXP48 Pro, plus 4 nights worth from the EXP96 Pro) or is there more of a multiplying effect?
Kevin,
Thanks for your question. Yes it is possible to use the parallel battery hook-up to charge two batteries at once.
