Smart Charger Comparison

I’m going to be using a top mounted battery (12s8p) without a BMS on my next build for easy swapping between a couple different boards.

I’m curious to hear if anyone has experience with either of these smart chargers, or anything similar.

I’ve been thinking about the cycle satiator for 5p, but 8p is gonna need lots of amps.

that second one looks pretty good.

To use a dual, usually you have to break the serial connection in your pack, as the grounds tend to be shared between the 2 sides.

For a huge pack, maybe something serious like this?

Yeah, it’s really going to be 2 6S packs connected in series. Though, I may borrow some elements of @michaelcpg’s pack design.

Yeah it’s pretty nice. Though it seems that you need to use DC to charge at high current on both channels at the same time.

I was using similar setup. For DC power supply grab some 24V or 48V ~1-2kW Server Power supplies for extra cheap on ebay europe has

But in the end I just grabbed simple 12S 8A charger and just bulk charging I got tired of disconnecting 12s to 6SP and other stories :slight_smile:

I’ll probably wind up doing that most of the time. I’ll have a battery monitor to make sure they don’t drift too far apart. Good idea on the server power supply. I’ll see what I can find in the states.

This charger will charge up to 12s and up to 25a It does require an external DC power supply though.


:+1: for the server power supply

wow never seen that before. and it has a balance plug inlet for a 12s? it looks like it. very nice.

I use two server power supplies. I followed the guide someone put up on an RC forum. Use them with isdt sc-620. Personally I balance each pack first then parallel together stopping at 4.15v just in case one cell is out of balance. Gonna get another sc620 to speed things up. I use my packs in a variety of projects too.15363884610932093052845

I have one. It comes with a breakout board for 12s. I tried to buy a 10s breakout board but they stopped responding. Will have to try making it myself if I want it badly enough.

It can do bulk charge (without balancing) at 12s, which is nice.

It needs a power supply too?

Yes. I think its usually separate on high power chargers for heat.
