Charge Circuit / Battery management

[bestkeptsecret]

Hi guys.

I'm trying to build a custom mod which will have 6 Cells in parallel and I want to incorporate a safe charging circuit which will have cell monitoring and balancing, over current protection and voltage cut off.

I'd like to build a 9A circuit ideally to give me 1.5 A per cell and I want to ensure no cell can be hit with any more than 1.7A.

Has anyone got any circuit diagrams /resource's /guides that might help me put something like this together?

Thanks

BKS

What type of mod will this be?

I'm not sure how to answer that, in what context are you asking?

6 Cells parallel. I'm going for a hybrid design. I want to be sensible about it and stick a current bypass, and cut off if the current draw spikes to a level where there has to be a fault.

With this sort of parallel setup I'm thinking running it full voltage like a mech with 0.2ohm coils will work just fine, but I do like the idea of going further, putting in DC-DC stepdown and PWM circuits and giving it a Full power mode / restricted power mode and a PWM mode.
