C20 Adjustable Battery Charger 12V 24V 36V 48V, 12A Pulses of High-Voltage Battery Desulfator Maintainer with Smart Chip for Lead-Acid LiFePO4 Lithium Batteries BLB-C20

Using this 20amp charger to charge Lithium phosphate batteries. I really like the versatility of voltages and also battery types as Will also work on lead acid. I do wish the charger covered the battery types and settings better. No direction other than it’s a “smart Charger “ and will handle the issues for you. A leap of faith when worrying about expensive batteries. Unit works well and as described

Bought to charge Taylor-Dunn industrial cart, as OEM on board charger cost 9x what this c cost. Works great! Can use for other batteries as well. Worth the price!

Heavy duty unit. Can charge several voltages. Can pulse charge lead acids which helps give more life to an older lead acid with build up on the lead inside. I do recommend this unit.

Quality charger, but small/cheap terminals to attach leads to charger.

Works great!

I got this charger but didn’t have a chance to use it right away. When I did it wouldn’t show any amp readings. I tested it with a couple batteries none would charge. I was passed the 30 day refund point at this stage so I opened it up to see if anything was obvious. The transformer has an extra wire coming off that wasn’t hooked to anything. I couldn’t identify any location where it should go. It has a bare metal end that was contacting the metal housing. I put my meter on it, the wire is hot with 120v ac! This thing could have electrocuted me or my kids at any point while we tried to use it.

Have a 48V electric forklift and it’s been sitting for a year. The main charger is a 208v 3-phase and we don’t have that available anymore. I bought this hoping I could recharge the forklift with a trickle charger. Magically it worked! Went from 1 bar to 10 bars. Fully charged. Left it in for a week so I’m sure it regulated itself. Not sure how long it actually took. The instructions weren’t perfectly clear to me but it worked regardless so I’m pleased.

I have a 1996 36 volt Club Car. This is the best charger I've had. It takes a long time to charge but the charge lasts a long time. It shows the voltage and amps as it charges. It charges to 44.1 v at about 7 amps when set to medium then it slowly goes back down to 0 amps at which time it is fully charged. It took over 8 hours to charge my 6 6 volt batteries that were about 80% when started. That is no problem for me. The wait is worth it. I haven't tried it on high yet.
