Xt30 Micro quad balance board for lipo battery charging

I recently bought a low-cost XT30 balance board that I would share here given it does the job I would expect at a low price: the ​XT30 1S-3S Plug Parallel Charging Board For IMAX B6 Charger. Although advertised as working with the Imax B6 charger, it will work with any 1-3s capable lipo balance charger that uses banana plugs.

The balance board can be used with 1,2,3,4 or 6 batteries with a XT30 connector and standard balance plugs for 1-3s batteries which will cover most micro builds. Each XT30 discharge lead is protected by a fuse if there is a large voltage differential on connection.

I also purchased this lead that I will modify to with an XT30 male plug from this set for input so that I can also use this balance board for my batteries with JST discharge plugs.

Below is a list of key rules for balance charging but certainly no exhaustive in terms of instructions:

1. Only charge batteries with the same amount of cells
2. Only charge batteries with capacity (mah) of within 10% of each other
3. Idividual battery cell voltage should be within approx 0.1v (check first)
4. Connection order: banana plug to charger, balance lead to charger, all of the XT30 discharge leads to the balance board and then all the balance leads to the balance board.
5. Set current as you standard charging current (I use 1c) multiplied by the number of batteries you are charging.
