The STRIX Joshua Bardwell XT60 4s Parallel Charging Board builds upon the extremely popular 3s, 4s, 5s, and 6s versions by adding color changing paint rather than tape for a cleaner look, and a power switch for the LCD voltage meter to help avoid over discharging if accidentally left unattended. As with all of the STRIX parallel boards, this will allow you to safely charge up to ten batteries at once! The main power lead comes equipped with an XT60 connector which is handy for popular chargers like ISDT. It also comes with an adapter to go from XT60 to traditional 4mm banana style that many chargers still use. The included balance lead is 7 pin XH style and one tab may need to be trimmed to fit properly into the balance socket depending on your charger's needs.
Charge up to ten 4s batteries at once
Self resetting poly fuses between cells with color change paint to easily see any errors
Voltage display adds safety by making it easy to verify battery voltage before connecting multiple packs
On/Off switch allows user to turn off display in case batteries are accidentally left unattended on the board.
Both XT60 and Banana plugs are included for power input
XT60 and XH plugs are used for power and balance
Overall current rating of 70A
Safety is a major concern for any form of parallel charging. Checking each cell of every single battery before connecting them together is extremely important! If you see a cell's voltage that is not like the rest, do not charge it with the others in parallel! To help with this, a cell checker is found at the top of the board. You need to check them one at a time before plugging them all into the board, however. Additionally provided are replaceable fuses between the main power leads to aid in preventing surges from one pack to another. STRIX suggests only parallel charging packs that are within roughly 0.1 volts per cell, or 0.4 volts for a 4S pack. So a pack that is at 15.0 volts total would be safe to charge with another pack that was 15.4 volts or 14.6 volts.
