PolyQuest Modular Balance Board

The latest revolution in parallel charging, our modular charge boards let you create the parallel board that you need. Mix and match any combination of main and balance connectors, and daisy-chain as many boards together as you need, with the added benefit of fuse protection for every connection.

This PolyQuest Modular Balance Board gives you two sets of PolyQuest 2S-8S balance ports wired in parallel, and is ready to attach to any of our modular charge boards to create a fully customized parallel charging system. Connect it directly to your charger to charge two packs in parallel, or combine it with other modular boards to create one larger parallel board. With connections rated for charge rates up to 40A, you'll never go back to charging single batteries again.

To connect this board to your charger, you'll need a balance adapter lead to connect the 8S connector on the board to the balance port of your charger. Or if you already have another modular board, just connect to the female balance port on that board to daisy-chain them together - no matter how many you connect together, you'll always need just one hookup to your charger.

Excellent constructionReview by Modular Balance Cables
High quality silicone wires & connectors. Solid construction. (Posted on 8/28/2017)
modular balance and charge boardsReview by Michael
I bought a whack of these at their November/early December sale prices and I think they will help to reduce the 'rube goldberg' improvised nature of my current setup.
Both the balance and charge boards are ruggedly constructed except for balance board exposed male input pins being vulnerable to getting bent. When I received them I pressed a small piece of 1/4" end grain balsa into these pins for protection from hanger rash. An alternative is to keep the balance adapter cable permanently attached to these pins for their protection.
I use the I-charger 308 duo and recommend buying several of these balance adapter cables - to fit the particular charger you are using - at the same time as Progressive seems to be the only retail outlet for them.

Communication was good and mailing cost to Canada was reasonable. (Posted on 1/13/2015)
