ISDTP20 800W 35A LiPo Battery Balance Charger Discharger Duo 500WX2 Dual Channel 1-8S Li-ion Life NiCd NiMH LiHV PB Smart Battery (Power Supply is NOT Included！

Charges LiPo super fast and efficient

Es lo que esperaba y buen producto

Unable to return/replace unit with Amazon. Unit worked quite well initially. Decent high power charger for series and parallel charging. After about 20 charges and 7 months, now I get a consistent charge problem on Ch2. Self test reveals buck converter failure (adc fail). This brand comes well rated by others, but I would definitely be very hesitant to purchase it again. Manufacturer warranty repair lasts only 180 days (6 months). Bummer...

This is an excellent dual channel DC-DC charger that I use to interface my trailer Titan solar generator battery with an external LiFePo4 battery. The batteries have different chemistries and charge/voltage profiles, so using this DC-DC charger between them allows me to independently regulate the charge/discharge voltage on each battery bank. I thought the P20 had Bluetooth capability when I purchased it but it doesn't. That's "my bad" for making that assumption based on another vender's website description of the P20 (as it turns out only the P30 has Bluetooth). I like the user interface buttons on the P20 much better than the touch screen interface on the Q8 or the P30, so I decided to keep it for my application.The only reason I rated this charger at 4 stars instead of 5 is because ISDT is reportedly removing an already existing BattGo support feature from sold units in its future firmware upgrades for existing customers. Personally I don't use the BattGo feature and I understand that ISDT sold their BattGo technology to another company, but downgrading existing functionality on units which have already been sold is not a good move from a customer perspective.

Charger works great. Can parallel charge my (2) 4s 8000mah lipos on one port.

Update: The seller and I have worked together to come to a compromise that makes us both happy. ISDT is a well known brand used by lots of hobbyists, seems like the one I got was just a bad unit.Unit worked great initially. Good high power charger for parallel charging. After about 15 charges I now get a intermittent error. Self test reveals buck converter failure. This brand comes highly rated by the quad racing community, but I would be hesitant to purchase again. Update: charger has failed completely, won't even turn on. Amazon has opened a line of communication between myself and ISDT to try to resolve the problem.

Great changer so far, like the fact you can charge two batteries at once. You need your own power supply up to 32 volts. Charge can charge up to 20 amps.
