This is the latest version of ParaBoard with self-resettable fuse protection. The PCB board is made of three ounce copper and the main circuit supports up to 40A current. All the balance ports are protected by resettable fuses (also known as polyfuse).

ParaBoard - XH can be used for batteries with JST-XH balance connectors, such as Align, Blue, E-flight, Turnigy, and our Glacier LiPo packs.

This device is to be used with a balance charger to simultaneously charge multiple lithium batteries in parallel. By this method you can significantly save time on battery charge process.

Principles and practices of parallel charging lithium batteries have been well discussed in the forums on RC Groups. This method has been proved to be a safe and efficient way to charge LiPo batteries, and is being widely accepted by more and more RC hobbiests all over the world.

Parallel charge can save your time significantly. If you charge four batteries at the same time, the charge current is four times of that you used for a single pack, and you need only approximately 1/4 of the charge time to charge every battery separately. Similarly, if you charge six batteries at the same time, the charge current is six times and time is only 1/6.

Multiple safe ParaBoards (V3) can be connected directly in order to charge more than four batteries at a time.

ParaBoard XH can be used for the following brands of LiPo batteries that have JST-XH balance connectors:

Air Thunder
Beyond Power
Blue Batteries
Common Sense RC V1 (reversed polarity)
Common Sense RC V2
DN Power (reversed polarity)

USPS First Class Mail and Priority Mail, Express Mail, and UPS services can be used for domestic addresses. Tracking number and delivery confirmation will be provided to the customer when they are available. If you have not received a tracking information E-mail, please log into your account and click the "view order" link, then click "Track your order" link to find out the tracking number and ship method.

USPS Priority Mail is typically delivered in 3 working days. But very occasionally a priority mail package may be delayed for several days in the mailing system. If delivery time is extremely critical to your order, we would recommend Priority Mail Express or other couriers.

Domestic First Class Mail is only 1-2 days slower than Priority Mail in delivery. We suggest domestic customers choose First Class Mail for an order under 15 oz to save shipping cost.

Real shipping cost is calculated according to package weight and distance, and can be found in the checkout page after delivery address is specified in the fields.

Any order of $200 and above requires addressee's signature confirmation upon receipt of the package. Please contact us in advance or leave a comment in the message box if you want to waive signature confirmation.

We always check the legality of potential fraudulent orders. This procedure may lead to 1-2 working days delay in shipping in some rare cases.

We do not ship products to shipping forwarding companies. Any order shows this kind of address will be cancelled and refunded without notification.


DHL, DHL Express, US Postal Service (USPS) First Class Mail, Priority Mail, and Express Mail (EMS), and UPS services can be selected for international addresses. Shipping cost is calculated according to package weight and distance, and can be found in the check out process. A package usually takes around 7-10 days to be delivered, or occasionally up to 45 days depending on the processing speed in your country, especially in some countries such as Brazil and Russia.

USPS First Class Mail is a budget shipping method. As soon as a First Class Mail package left USPS Chicago hub there will be no tracking information available. If you need detailed tracking information and timely delivery please do not use this shipping method.

Presently we cannot ship lithium batteries internationally by US Post Service or any other air shipping method. Please select UPS Ground if your order contains LiPo or LiFe battery.

We do not ship products to shipping forwarding companies. Any order shows this kind of address will be cancelled and refunded without notification.

Follow the instructions and it works great!

I bought a V3 ParaBoard with Deans connectors, and one with EC3 connectors, however, I'll probably eventually standardize all my LiPo packs with Anderson Power Poles, so the Anderson Power Pole ParaBoard is next on my list.

Using the ParaBoard is easy:

1) All battery packs MUST have the same number of cells (eg. All 2S, or all 3S, or all 6S etc).

2) Each LiPo pack can have the same, or different capacities (eg. 2200mAh, 3300mAh, 5000mAh, etc)

3) Each LiPo pack's overall voltage MUST be within 0.1V of every other LiPo pack that will be parallel charged. Check with a LiPo voltage tester.

4) No individual cell in any of the LiPo packs to be parallel charged should be more than 0.2V different from any other cell in any other pack. This is easily checked with a LiPo voltage tester that shows the individual cell voltages. Several voltage testers show the difference between the cell with highest voltage and the cell with the lowest voltage in a pack, with a simple push of a button.

5) Add up the capacities of all the LiPo packs to be charged (eg. Charging three LiPo 3S packs.. Two 2200mAh, and one 2500mAh... total capacity is 6900mAh, or 6.9Ah).

6) If T = Total Capacity (in Ah), and C = Charge rate (LOWEST C rating for the packs, so as not to charge a low-rated pack too quickly), then:

Charging Current = T x C

eg. For the example in step 5 above, to charge all the packs at once, at 2C...

6.9Ah x 2C = 13.8 Amps

Set your charger to charge 3S LiPo packs at 13.8 Amps. All 3 packs will be charged in the same time it would normally take you to charge just one pack, at 2C!

Another example: To parallel charge four 1300mAh batteries at 3C:

4 x 1300mAh = 5.2Ah
5.2 x 3C = 15.6 Amps

A good video to watch is this one: https://www.youtube.com/watch?v=Qkb75ZKHCMU however, it advertises a competitor's, lower quality product. Ignore the competitor's knock-off product, but follow the directions, if you found the above hard to follow. Once you get the hang of parallel charging, it'll seem simple!

Wheres the Beef?

I finally ordered something else... they have been out of stock forever.

too bad for me / us
