I was looking at purchasing the Hyperion 1420 as I've read good things about them last year while on a search for charging solutions. I was just about to purchase when I decided to research to see if they were still the "ONE" or not.
I'm looking for charging solutions for my LiFePO4 batteries.
I purchased a lot of stock of 13.2v nom 4s4p and 4s3p (9.2 and 6.9ah) A123 to sell here and as Motorcycle/ATV/Snowmobile start batteries. Oh, and to experiment with electric vehicles too! lol
Each battery has JST-XH.
When putting 6 in series (24s) gives me 84v HOC (79.2v nom).
To charge, I have 2 taps at the first 3 in series (39.6v nom) and then the second 3 series.
I use a 12s LiFePO4 bulk charger (43.8v) with 3 Battery Medics on the JST-XH (one on each 4s4p battery)put into Discharge mode of 3.6v, so the minute that a cell group see's 3.6v, it starts to discharge that 4s group.
My chargers are isolated so I can charge both 12s 39.6v groups at the same time without breaking the pack down, but for extra safety while I charge, I only charge one 12s group at a time.
Doctor Bass is using the BC168. I believe it charges at the CELL level.
Nice charger, but do note that YOU MUST break your pack down if charging multiple batteries simultaneously. Packs CANNOT be in series if you want to charge more than one pack at a time. So, If I decide to charge in this manner, I must adopt a mind set of Pack Breakdown.
I'm sure that the RC guys would really like this charger. Because it charges at cell level, you can put different capacity batteries (up to 6s) into the paraboard simultaneously
