We got your RFQ for the wheelchair battery packs, and the 100Ah or 200Ah LiFePO4 units we have in stock should fit your needs pretty well — they're built around a 12V nominal votage with a BMS that handles over-charge, over-discharge, and cell balancing automatically, so you don't have to worry about thermal runaway in the medical equiment.
Cycle life is over 3000 cycles at 100% depth of discharge, which basically means you'll get years of daily use before capasity drops off — most buyers go with teh 200Ah for electric wheelchairs since it gives them a full day of operation without recharging, but the 100Ah works fine for lighter backup roles.
ABS enclosure is rated IP56, so it's water and dust resistant — we've had these sit in outdoor solar setups for months without issues, though they're not meant for submersion or anything like that.
Weight runs about 12kg for the 100Ah version, give or take a bit depending on the exact dimensions you need — our company can customize the casing size to fit your wheelchair battery compartment, but lead time on custom shapes is usually 20 days or so.
Operating temperature range is 0°C to 45°C for charging and -20°C to 60°C for discharge, so it handles cold storage fine, but don't try charging below freezing without low-temp cutoff — that's a common mistake with LiFePO4 chemistry.
Anyway, our company have the 100Ah and 200Ah ready to ship, MOQ is 10 units, and we include a COA with each batch — just confirm the terminal type you need and we'll get a quote out by tomorrow.
MOQ is 100 units for standard models, but we can start with 50 if you need a sample. Lead time is about 15-20 working days for the 200Ah; 100Ah can be ready in 10-15 days.
Yes, we provide UN38.3, CE, and RoHS reports with every order. For medical equipment compliance, we can also furnish IEC 62133 if required.
Absolutely, dimensions are fully customizable. Just send us the exact space you have, and we'll adjust the enclosure size while keeping the 12V 100Ah or 200Ah specs.
It stores well for up to 12 months at 50% charge in a cool, dry place. Keep it between -10°C and 35°C for best results, and avoid full discharge during storage.
Yes, the built-in BMS includes over-temperature protection on both charge and discharge. It will cut off if the battery exceeds 60°C, so it's safe for continuous medical device use.
