CellPro Adapters

These Cellpro adapters provide interconnectivity between FMA Direct’s Cellpro 4s or Cellpro 10s cell balancing chargers and many currently-available lithium polymer battery packs. The Cellpro 4s adapters will interconnect 2s to 4s battery packs. The Cellpro 10S adapters will interconnect 2s to 6s battery packs. The Cellpro 4s adapters listed on this page may be used with the Cellpro 10s charger by connecting to the 5s-to-4s adapters that come standard with every Cellpro 10s charger. The Cellpro 10s adapters listed on this page will not interconnect with the Cellpro 4s charger.

Currently, FMA manufactures adapters that will interconnect up to 6s battery packs. In order to charge packs larger than 6s using the Cellpro 10S charger, you are required to adapt FMA’s Cellpro balancing tap connectors to your packs. See the attached link for instructions on wiring 2s to 10s packs using FMA’s balancing tap pigtails, PN’s CPBP7 and CPBP6P-10, http://www.helistore.ch/pdf-files/FMA-Pigtail-Cables.pdf

Alternately, on battery packs larger than 6s that implement the wiring scheme used on Thunder Power packs, you may use two adapters (PN:CP10S-TP/PQ6S) from FMA to charge one pack. One adapter must be plugged into channel one on the Cellpro 10s charger, while the second adapter must be plugged into channel two. Each of the two balancing tap connectors on the pack will then plug into the separate FMA adapters based on the number of series cells in the pack. Example: You have a 10s Thunder Power pack wired as (2) 5s packs in series. The balancing tap connector from the first 5s pack will plug into the 5s port on the adapter and channel one on the CP10s. The balancing tap from the second 5s series pack will plug into the 5s port on the second adapter on channel two of the CP10s. In this example, the second pigtail coming off of each of the CP10S-TP/PQ6S adapters does not get connected to anything. This second pigtail, labeled “Connect for 6s Only” is required only when a single, 6s pack is connected to the Cellpro 10s charger.
