Its a few 0.5 or 1 ohm resistors and 2200uf caps, so expense is minimal.
But I guess I could make a little board that has the bridges, caps and a linear reg to make it easier to charge a bunch of batteries in series.
Still takes a fairly substantial battery investment though.

The 18650 type? Looks like about 1/2 the price of the bigger ones over here, with shipping.

Wow, that's a bargain for lifepo4 batteries. At that price I'd use them everywhere :)
