ExpertPower 12V 5Ah 锂铁磷酸盐深循环充电电池 

  • 更长的使用寿命: 我们的 LiFePO4 电池可提供 2500 - 7000 次循环和 10 年使用寿命,而典型铅酸化学电池可提供 200 - 500 次循环和 3 年寿命。
  • 高效动力: 我们的 LiFePO4 电池的平坦放电曲线在高达 90% 的容量使用情况下保持在 12V 以上,与铅酸电池的运行时间仅为 50% 相比,运行时间得到了天文数字的提升。
  • 无可挑剔的轻量级: 我们的 LiFePO4 电池的重量仅为铅酸电池的 1/3,这使得它成为房车、船舶和离网应用在考虑牵引或移动性时有争议的选择。
  • 完善的保护: 锂电池独特的内置电池管理系统(BMS)可防止过度充电、深度放电、过载、过热和短路以及过低的自放电率,确保长达 1 年的免维护存储。

Tests slightly under rated capacity

Slightly below rated capacity (2.5% less at 125 Wh). Charged using CC/CV up to 14.4V, no more than 2A during CC, and at the end of charging it was drawing just a few mA as expected. Let sit for a day. Resting OC voltage was 13.85V. Ran test at 0.15C rate using an Ohmite shunt and voltage measured at the battery terminals (not at the load!). Stopped when voltage dropped to 10V. 125Ah result. Can't complain too much about that, but most batteries I buy these days test at slightly over the rated capacity.

Good batteries for a steady discharge

Good batteries originally bought for an old 24V electric bike but these have an internal circuit breaker so they will cut out when throttle is engaged in the bike. I replaced them with some hi discharge batteries which worked great. I used these in a homemade power box and they are working just fine.

Good battery for QRP radio

Great little battery. Using it to power an FT-817ND amateur radio. It holds up for several days of active use. No problems with the battery at all to date. Good price and a good product.My bigger battery ran out for my FT-891 and this little battery stepped in for a while at 100w and lasted for over an hour, so it definitely punches well above its weight.
